Operating Instruction

Reversible Ploughs

Raven (Shearbolt) Raven (Hydro)Avant (Auto-reset)

For Your Own Safety

In this enclosure to the operating instructions you will find some general rules of conduct explaining how to operate the implement correctly - and some safety advice which we advise you to observe for your own safety! The list is very extensive, and some of the advice does not specifically relate to the implement supplied. However, the summary of advice is to remind you of safety guidelines which are often unconsciously ignored when operating the machines and implements on a daily basis.

1. Authorized Use

The implement has been specifically built to perform standard operations pertaining to agricultural work (authorized use).

Any type of usage outside of these parameters is deemed to be improper usage. The manufacturer accepts no responsibility for damage resulting from such usage, and the risks are to be borne solely by the user.

Within the bounds of authorized usage it is also necessary to adhere to the manufacturer’s prescribed operational, maintenance and service conditions.

The implement may only be used, maintained or serviced by people who are familiar with such an implement and aware of the risks involved. Please also ensure that all safety instructions are passed on to other users.

It is important that any and all relevant accident prevention regulations and any other generally recognized safety, industrial hygiene and road traffic regulations be observed.

Modifications to the implement made by the user will void any liability on the part of the manufacturer for any resulting damage.

2. General Safety Advice and Accident Prevention Regulations

• Before starting up your implement and tractor, please check that it is roadworthy and

operatively safe.

• Please observe all generally valid safety and accident prevention regulations.

• The warnings and signs found on the implement are there to provide essential data needed to

operate the unit safely. Please observe these for your own safety.

• When using public roads always follow the relevant traffic regulations.

• Before commencing work, ensure that you are familiar with all devices and operating controls

as well as with the functions these perform. It is too late to do so once the implement is in operation!

• Operators should wear tight-fitting clothing. Try to avoid wearing loose clothing wherever

possible!

• The machine should be kept clean to prevent the risk of fire!

• Check the immediate surroundings before driving off and putting the machine into operation!

(Beware of children!) Ensure that you have sufficient visibility!

• Riding on the equipment during work or transportation is not allowed!

• Implements should be correctly coupled and only secured to the specified appliances.

• Special care is to be taken when coupling and uncoupling implements to or from the tractor.

• When coupling and uncoupling supports, always position them correctly. (Stability)

• Always ensure that weights are only added correctly to the specified mounting points.

• Observe all permissible axle loads, total weights and transportation dimensions.

• Check and mount transportation equipment such as lighting, warning devices, and guards, if

necessary.

• Ensure that the release ropes used for rapid coupling and uncoupling hang loose and do not

automatically release when in a low position.

• Never leave the operating platform when in transit.

• Road, steering and braking performance will be influenced by mounted or attached

implements and ballast. Therefore make sure that you have sufficient steering and brake capability.

• Account for the width of the implement and its working load when taking corners.

• Only operate implements once all the safety devices/guards have been mounted and are in

protection mode.

• Keep clear of working areas at all times.

• Keep clear of rotating and swinging parts on the implement.

• Ensure the swinging parts are clear of bystanders before operating any hydraulic folding

frames.

• Power-steered parts (e.g. hydraulics) can cause crushing or amputation!

• On high-speed implements with ground-driven implements beware of after-running swinging

parts! Only approach once the implement is at a complete standstill!

• Before leaving the tractor, lower the implement to the ground, switch off the engine and

remove the ignition key!

• Do not allow anyone to stand between the tractor and the implement without first having

secured the vehicle against running away by putting on the handbrake and/or using wheel chocks.

• Ensure that the folded-in frames and lifting equipment are securely in transportation position.

• Fold in and lock the packer catching arms before transporting on roads.

• Lock the marker arms to transportation position.

2.1 Coupled Implements

• Before coupling or uncoupling an implement to the three-point linkage, position the operating

device in such a way as to prevent unintentional lifting or lowering.

• When using the three-point linkage it is vital that the coupling configurations of the tractor

and implement correspond or are co-ordinated.

• There is a risk of injury through crushing or amputation near the three-point linkage.

• When using the external controls to operate the three-point linkage, keep clear of the area

between the tractor and the implement.

• When the implement is in transportation position, always ensure that the tractor’s three-point

linkage is sufficiently locked at the side.

• When transporting a raised implement on public roads ensure the control lever is locked in

place to prevent accidental lowering.

2.2 Mounted Implements

• Secure the implement to prevent it from running away.

• Observe the max. permissible bearing loads for the trailer coupling, swinging drawbar or

hitch.

• If a drawbar trailer is used, ensure that there is sufficient manoeuvrability at the towing point.

2.3 PTO Drive (applies only to PTO-driven implements)

• Only use the drive shafts specified by the manufacturer.

• A pipe shield and protective bell must be mounted on the drive shaft as well as a PTO guard –

also possible on the implement - and must be in perfect working order.

• Ensure the specified pipe covers are used on the drive shafts when in transportation and

working position.

• Only couple and uncouple the drive shaft once the PTO has been disengaged, the engine

switched off and the ignition key removed.

• Ensure that the drive shaft is mounted and secured correctly at all times.

• Secure the drive shaft guard by locking the chains in place to prevent them from turning.

• Before engaging the PTO make sure that the PTO speed chosen on the tractor complies with

the permissible speed of the implement.

• When using ground speed power take-off ensure that the speed is regulated by the travel

speed and that the direction of rotation changes when reversing.

• Before engaging the PTO make sure that the area of danger around the implement is free of

bystanders.

• Never engage the PTO when the engine is switched off.

• When working with the PTO, keep the area around the rotating PTO and drive shaft clear of

any bystanders.

• Always disengage the PTO where the bends are too big and it is not needed.

• Caution! Beware of after-running gyrating loads after disengaging the PTO! Do not stand too

close to the implement during this time. Only begin working on it once it has come to a complete standstill. It is essential that you switch off the engine and remove the ignition key.

• Before cleaning, greasing or adjusting a PTO-driven implement or its drive shaft, always

disengage the PTO, switch off the engine and remove the ignition key.

• Place the uncoupled drive shaft on the specified support.

• Cover the stump of the PTO with a protective cover after dismounting the drive shaft.

• Any damage which may arise should be repaired immediately. Never work with a damaged

implement.

2.4 Hydraulic Equipment

• Hydraulic equipment is under very high pressure.

• When connecting hydraulic cylinders and motors ensure that the hydraulic hoses are

connected as specified.

• When connecting hydraulic hoses to the tractor’s hydraulics ensure that the hydraulics are

depressurized on the tractor and the implement.

• Where it is necessary to connect hydraulic functions between the tractor and the implement,

the coupling sockets and plugs should be marked to prevent faulty operation. Mixing up the connections will reverse the functions (e.g. lift/lower) - Risk of injury!

• Check the hydraulic hose connections at regular intervals and replace if damaged or aged. The

replacement hydraulic hoses must comply with the technical requirements stipulated by the implement manufacturer.

• When looking for leaks, use suitable aids and resources to prevent injury.

• Liquids that leak at high pressure (hydraulic oil) can penetrate the skin and cause serious

injury! In the event of injury, consult a doctor immediately. Risk of infection!

• Before working on hydraulic units, lower the implement, depressurize the system, switch off

the engine and remove the ignition key.

2.5 Brakes and Tyres

• Check that the brakes are functional before every journey.

• Thorough checks are to be performed on the brake systems at regular intervals.

• Adjustments or repairs to the brake system may only be performed by qualified staff or

recognized brake service centres. Only use the prescribed brake fluid and replace as specified.

• When working on the tyres please ensure that the implement has been securely parked and

cannot run away (wheel chocks).

• Fitting tyres requires having sufficient training and the correct fitting tools.

• Wheel and tyre repairs may only be performed by qualified staff using the correct fitting

tools.

• Check the air pressure at regular intervals observing the prescribed air pressures given.

2.6 Maintenance

• Service, maintenance and cleaning work as well as the elimination of malfunctions should

only be carried out once the drive unit has been switched off and the engine has come to a standstill. Remove the ignition key.

• Check that the nuts and bolts are snug, and tighten as necessary.

• When carrying out maintenance work on a raised implement always secure using suitable

support elements.

• When replacing bladed working tools use the appropriate tools and gloves.

• Dispose of all oils, grease and filters in a due and proper manner.

• Always disconnect the power supply before working on electrical equipment.

• When performing electrical welding work on a tractor with a mounted implement disconnect

any cables connected to the generator and the battery.

• Gas tanks must only be filled using nitrogen to avoid risk of explosion.!

• Spare parts must at a minimum comply with the technical requirements given by the

manufacturer of the implement. We therefore recommend that for your own safety you use original parts only!

2.7 Additional Hints and Tips: Mechanical Seed Drills

• Danger! Beware of rotating and oscillating machine parts when performing a calibration test.

• Only use the tread plates for filling purposes. Riding on the machine during operation is

prohibited.

• When transporting on public roads protect or remove the thrust collars on the pre-emergence

marking.

• When filling the seed hopper, observe the information provided by the implement

manufacturer.

• Lock row markers in transportation position.

• Do not place any foreign parts in the seed hopper – the agitating shaft also rotates during

manoeuvring.

• Observe the permissible filling quantities.

Safety precautions

Prevent injuries. Do not allow anyone to remain between the tractor and

the unit while it is being coupled or uncoupled. Likewise, do not stand between the tractor and the plough when operating the hydraulic external controls.

Before coupling or uncoupling, set the tractor’s hydraulic lifting system to ”Position Control”.

Ensure before starting up at the beginning of each shift that the tractor and plough are both in safe operating condition. The user is responsible for safety.

Ensure that there is sufficient space to manoeuvre, and attach suitable and sufficient weights to the front of the tractor to preserve steering stability and prevent the tractor from rearing.

There is a danger of suffering crush injuries or amputation in the area of the three-point linkage/plough head stock, and also when carrying out width adjustments or turning.

Ensure each time the plough is used, and while it is being towed, that no one is standing nearby.

Never allow anyone to climb onto or ride on the plough, or remain in the danger area (swing-out zone).

Do not carry out adjustment or maintenance tasks before first lowering the unit on the ground.

Use the correct tools and wear suitable protective gloves when fitting parts with cutting edges.

When working along the contour line of a steep slope, take into account the centre of gravity when the plough is raised.

Lock the hydraulic controls fitted to the tractor when transporting the unit. This is to prevent accidental activation.

Never leave the tractor unattended without first lowering the plough, cutting off the engine and removing the ignition key.

Before starting up for the first time - and after any prolonged period without use - check all screws and bolts for tightness, ensure all bearings are sufficiently greased, check the hydraulic system for leaks and ensure the tyres are inflated to the correct pressure.

Warning notices (pictograms) Warning notices are used to indicate possible

hazards; their purpose is to help ensure the safety of all those involved in operating the plough.

Please refer to the appendix entitled ”Pictogram symbols” for an explanation of the warning notices.

1 2 3 5

See Fig.1 (e.g. 3 = numbered series in the explanation) for details of their locations.

Replace any missing warning notices. These items can be ordered from RABE as spare parts.

Set-up

Ensure that couplings on the three-point linkages are compatible (Cat.: Tractor/Plough).

Check tractor tyre pressures and measure the inner

clearance between the tyres. This distance should be approximately the same for the front and rear wheels, and the inner walls of the tyres should align (2/1).

Set the lower link arms to the same height. Set the lower link pins (3/1) to a height where the

plough can be raised sufficiently, and/or the lower link arms are in the correct position during operation. (See tractor operating manual).

Set the top link on the plough head stock so that it lifts slightly relative to the plough during operation. (Secure the top link pin to prevent it turning (4/1); Fit on the opposite side a washer and lynch pin.

Secure the three-point linkage in accordance with safety regulations.

Connect the hydraulic hoses according to protective cap colour.

Turnover: Connect the two hoses with the double acting control unit on the tractor (red); The hose marked ‘P’ on the hydraulic turnover cylinder should be used for the ”UP” function. For single acting turnover use the hose from ”T” direct into the oil reservoir of the tractor lift and the second hose to the single acting spool valve. In this case an additional single-action spool valve is required for a hydraulically operated pick- up arm for furrow press operation.

Hydraulic front furrow adjustment: Connect the two hoses with a double acting spool valve on the tractor (blue).

HydroAvant models: Connect the one hose for the hydraulic auto reset system with a single-action spool valve (white).

Turnover test

Raise plough. Release parking prop. Activate the hydraulic control from ”Neutral” into ”UP”

position until the plough has rotated compl. and is flush with the vertical adjuster screw (3/2),

or - in the case of a an hydraulic angling device – until the re-angling sequence is also completed. Then put the control back into ”Neutral”.

After about eight seconds, a new turnover sequence or immediately if the hydraulic control is operated briefly in ”Down” position.

If, when reversing, it emerges that the plough is not sufficiently raised (despite the lower link pins being fitted in the bottom position), the lifting rods of the three-point linkage will need to be shortened. If this is also not sufficient, attach the top link at a higher point on the plough.

Beware of the raised plough colliding with other objects, e.g. the open rear window of the tractor cab, including when turning.

Preliminary adjustment

: from centre turnover shaft to land side of first body

The ”Point of draft” (6/Z) and the front furrow width can be already pre-adjusted before setting out to work. Final adjustment is then carried out on-site during work.

In the RABE adjusting centre, both settings are clearly configured and separately adjusted.

Draft: using the turnbuckle (8/1) or adj. sleeve on angling cylinder (7/1) to align the landsides in a parallel line to the central turnover shaft (axis of rotation). The following table indicates the approx. length of the turnbuckle or angling cylinder (6/D) depending to the

working width (cm) of the plough model:

hydraulically to adjust dimension (C) which is the horizontal distance from centre turnover shaft to the land side of the first body. Supposition is that the plough is in a correct vertical alignment.

Dimension (C) depends, along with other items, on the inner clearance between the tyres (A ) and furrow width per body (B). If no model-specific furrow width is shown in the table, dimension (C) should be regarded as an intermediate value– see example ”b”.

Do not carry out hydraulic front furrow width

adaptation under load or when the plough is lifted.

Use during operation The lower link arms of the tractor must be able

to move sideways during operation. Check chains or stabilisers should be slack. However, they should be laterally rigid when the unit is raised, insofar as this is permitted by the design of the tractor.

Working depth: Select ”Draft” or ”Mixed Control” on

the hydraulic system and choose desired working depth.

Adjust the top link so that the plough beam is parallel to the ground surface.

With bottom link sensing on the tractor the top link can be fitted to the slotted hole position on the plough head stock for improved draft control and relieve of strain on the hydraulic three-point system. The top link pin should rest against the forward shoulder allowing some play during work. This improves also faster penetration of the plough at the start of a furrow.

90°

Depth wheel: If the plough is fitted with a depth

wheel or transport/ depth wheel (combi- wheel), this is not brought into contact with the ground until the ploughing depth adjustment has been carried out – Do not exert to much load on the wheel.

Depth setting using spindle (10/1 or 11/1): Using the eccentric collar (10/2 or 11/2) differences

in depth between the left and right hand ploughing side can be equalised.

Plough inclination / tilt: Each side of the plough is adjusted separately. Ground surface and plough beam should be at approximately right angles (90°) to each other. (See Fig.12).

Spindle (9/1) for the right-hand bodies Spindle (9/2) for the left-hand bodies

The inclination control can also be used to carry out a depth alignment of the front bodies. If the front furrow of one side is too shallow, it should be aligned by inclining it more steeply relative to the ploughed side.

Draft alignment and front furrow width

Adjustments should be carried out in the following order: Draft adjustment first and then the front furrow width. Future adjustments to the front furrow width subject to changing working depths or ploughing on a slope– do not greatly influence the draft setting.

Draft: (Position of the lower link arms): The tractor should run along the furrow without any

lateral draft. If the laterally mobile lower link arms are not

approximately centred relative to the tractor, causing lateral draft, correction should be made at the turnbuckle (15/1) or angling cylinder (14/1). Turn cylinder limit stop sleeve (14/2) with the spanner provided (14/3).

Secure with screw (14/4) in groove. Shorten turnbuckle / cylinder – Three-point

linkage creeps towards ploughed side Extend turnbuckle / cylinder – Three-point linkage

creeps towards unploughed side Example: If the tractor is pulled at the front end

towards the ploughed side, shorten the turnbuckle or the cylinder somewhat. After adjustments do not forget to extend the cylinder fully against the limit stop.

Front furrow width: This must be adapted to the working width of the other bodies.

Using the spindle (14/5) – or the hydraulic system – to shift the plough beam parallel:

Beam displaced towards ploughed side – front furrow narrower

Beam displaced towards unploughed side – front furrow wider

Do not carry out hydraulic front furrow width adaptation under load or when the plough is lifted.

Working width adjustment

The working width for each body is adjustable in four steps. Use locating pin (17/1) for adjusting and fit washer under both sides.

Slacken the pivot bolt (17/2) only slightly if the console needs to be swivelled.

All bodies must be set to the same working width.

Torque tension of locating pins and pivot bolts (17/1 & 17/2)

110 & 120 mm beam - 410 Nm 140 mm beam - 710 Nm

For your owm safety: Use gloves and only suitable

tools and spanners (25/3) as provided ! ( RABE part no. 4798.00.99).

It is important to observe the torque tensions

stated in this manual ( see pages 8, 10 & 12)

Skimmers and disc coulters are adjusted at the same time.

When changing the working width, the wheel bracket must be shifted as well (17 & 18) at the same pattern.

Every time the working width is changed realignment of the draft and front furrow width is absolutely necessary. Refer to ”Preliminary adjustment” page 5 (6D & 6E).

Pick- up arm for furrow presses

Transport position: Fix the connecting rod (19/1) at the main arm (19/2). On AVANT – models swing the outer end of the arm (20/1) forward.

Working position: Fix the connecting rod (19/1) so, that the pick- up arm is in an rectangular position to the travelling direction.

On the arm of the hydraulic disconnecting device there is a set of holding pins (19/3) provided which can be fitted on both ends of the hook, to pull the

furrow press around obstacles with the plough in lifted position.

To operate the disconnecting device when the device is connected to the turnover ram (marked T on ram), the hydraulic control must be activated in opposite direction as when reversing the plough.

Skim coulters

There are three ways to adjust the skimmers. Lateral to the plough body by turning the cranked stalk. The clearance in front of the bodies by turning the guide plate around (21/4) and by turning the cranked stalk. The working depth by shifting the skimmer on the stalk up or down.

The red markings on the toothed segments (21/3) denote the standard basic adjustment.

When fitting the toothed segment at the bottom (21/

1) and the thrust piece (21/2) make sure that the numbers stamped on are facing upwards.

Trash boards

The trash boards are supported from the rear by adjustable bolts (22/1) which should be resting against the plough leg. The front of the trash board should be resting on the mould board. There are slotted holes provided at the holder bracket for height adjustment.

ca. 5 cm

ca. 2-4 cm

Subsoilers

Due to stability problems it is not permitted to store the plough resting on the subsoiler units. Remove shear bolts (22/3) and turn subsoiler rearwards out of way. The shear bolts are provided as overload protection. In stony conditions the use of subsoilers is not permitted. Depth adjustment is by means of

Disc coulters

The depth is adjusted on the notched segments (23/1).

There should be a minimum clearance between the disc bearing housing and the ground of apprx. 5 cm (2 ”) to avoid excessive wear on the housing.

To obtain clean work the slacken bolts (24/2 & 24/3) must be set, so that the cut is apprx. 2 – 4 cm away from the furrow wall (fig. 23).

Lateral movement of the disc is restricted by the collar (23/2). Make sure that the collars are always properly tightened.

Shear bolt overload protection

All plough models are fitted with shear bolts (25/1). Also the AVANT auto- reset models. The bolt head should always be on the plough leg side.

After fitting a new shear bolt, ensure that the other leg pivot bolt is tightened.

There is a danger of crush injuries when the ”activated” plough body swivels back.

Always approach the plough bottom from behind only– the affected side of the plough faces downwards.

If the swivelled bottom is ”blocked”, slightly slacken the plough leg pivot bolt. Use suitable tools. There is a special spanner provided (25/3) part no. 4798.00.99.

Also to be used for the console bolts (see page 8). Wear protective gloves.

It is important to observe the torque tensions

1 mm

stated in this manual ( see pages 8, 10 & 12) ”HydroAvant” & "Avant" auto reset devices:

The reset force on both systems is adjustable. The HydroAvant system can be adjusted from the tractor seat.

"HydroAvant" hydraulic auto reset system: Connect with single acting spool valve. To alter oil pressure open the shut-off valve (27/1).

The minimum oil pressure should be 110 bar and the maximum apprx. 200 bar.

After carrying out pressure adjustment shut valve (27/1) again.

Adjust the reset force (oil pressure) so that the plough bodies are kept firmly in the ground, but can easily release when encountering obstructions. Adjust the clearance between the angle lever (28/2) and limit stop (28/3) to about 3 mm – using the adjustment screw (28/1). To do so reduce hydraulic pressure.

”Avant” mechanical auto reset system

Turn screw (29/1) clockwise – less reset force Turn screw anticlockwise – more reset force

Important: leave a minimum clearance of 1 mm between the angle lever (29/2) and limit stop (29/3).

In extremely heavy but stone-free ground, the ”Avant” reset device can be blocked with a special locking device (29/4) available as accessory.

Caution: the ”Avant” mechanical auto reset device works under strong spring tension. The built-in compression spring is highly pre – tensioned by the factory.

It is very dangerous to dismantle the compression spring without special tools provided by the manufacturer.

The spring must only be dismantled by properly qualified technicians using the special tools.

On the ”HydroAvant” unit, release system pressure before dismantling.

The clockwise-turning plough side (r. h. bodies) faces downwards.

If a hydraulic angling device or hydraulic width adjustment system is fitted, locate the plough in ”narrow” mode behind the tractor.

Swivel pick - up arm for furrow press in and secure with pin.

Immobilise the tractor lower link arms sideways. Set hydraulic spool valves on tractor inactive.

Observe transporting precautions on page 14.

Transporting with Combi – wheel (combination of depth and transport wheel):

Raise plough slightly, Withdraw pin (30/1), turn wheel slightly along the vertical axis and secure by inserting in hole (30/3).

Fix in place using locking pin (30/2). Insert pin (30/5) in hole (30/6, 31/6).

Engage the centring lock under the plough head stock (32/1) and rotate the plough slowly until it will lock automatically in the centre position.

Important: Release top link on plough.

Changing to operating position: Attach top link

and raise plough. Release centring lock (32/1) and rotate plough into

operating position. Withdraw pin (30/1), turn wheel slightly and secure by inserting in hole (31/4). Insert pin (30/5) in operating position into hole (30/7).

Parking the plough

Park on level ground on the clockwise-turning bodies (r. h. bodies) with the parking stand down.

Adjust stand length accordingly. Release pressure before uncoupling hydraulic hoses.

Protect hydraulic hose plugs from dirt. Grease all wearing surfaces. If subsoilers are fitted, loosen the shear bolt (22/3) and

swivel the subsoilers towards the rear.

Maintenance

Before starting work on the plough attached to the tractor, shut off the engine and remove the ignition key.

DO NOT work on a raised plough. ALWAYS lower the plough and release hydraulic

pressure before carrying out work on the hydraulic system.

Always dispose of used oil as required by law.

After the initial hours of work (approx. 8 h), retighten all screws and bolts, and check regularly for tightness thereafter.

On the configuration with trash boards, ensure that the supporting bolts are fitted. (22/1).

Lubricate all bearings regularly using multi-purpose lithium-based grease:

E.g. on turnover cylinder, turnover shaft, vertical adjustment screws (3/13), guide rails (33/2), spindle bearings (33/3), centre pin (33/4), pivot pins on angling ram (33/5), hydraulic furrow press arm, disc coulters and depth / combi – wheel.

When used on very stony soil, lubricate the bearings on the auto reset system daily . (Avant / HydroAvant models).

Check tapered roller bearings on depth wheel, disc coulters and turnover shaft and readjust if necessary.

The swivelling speed on the Combi - wheel during turnover can be in- or decreased by means of tightening or slackening the castellated nut (34/1).

Apply oil to linkages, ensure spindles can move freely. Carry out regular inspections of the hydraulic supply

hoses and replace them at the first sign of wear or brittleness.

Pressure hoses have a fixed natural working life and should not be used for more than 5 - 6 years.

When hosing down the plough (especially when using a high-pressure cleaner), do not point the jet of water directly at the bearings.

Whenever the plough is parked up, apply an anticorrosion product to all wearing surfaces and smear the piston rods with acid-free grease to preserve them.

Touch up damaged paint work.

Replace wearing parts on time. Shares and land sides before the frog of the plough body begins to wear away.

When using shares with bolt – on points reverse the tip first and then move forward.

Use ONLY original RABE parts and components and new original bolts and nuts.

Tyre pressure: Depth wheel – 2.50 bar Combi – wheel – 3.75 bar

Precautions when transporting

Transfer to your national law if necessary.

Place unit in ”transporting position”; check that it is ready to move.

DO NOT ride on the unit while it is being moved. DO NOT remain in the danger area near the machine.

Observe road traffic legislation with respect to speed limits when transporting the unit; when transporting with jockey wheel, do not exceed 25 km/h (= semimounted unit). Take care on curves: the mounted implement (or semimounted unit) swings out when turning.

Follow your local traffic regulations.

Road traffic legislation normally make the user liable for insuring the combination of tractor and towed unit for the purposes of transportation on public highways.

Attached implements must not affect the safe movement of the tractor and trailer unit. Ensure that attached implements do not lead to loads in excess of those permitted on the tractor axles, or the permitted maximum total weight, or the maximum weight-bearing specifications of the tyres (depending on speed and inflation pressure). The front axle load should amount to at least 20 % of the total tare weight of the vehicle, to enable it to be steered safely.

Maximum transporting width is 3 m. Excessively wide loads require official permission.

No part may protrude from the machine in such a way as to endanger traffic more than that which is unavoidable (§ 32 German Road Traffic Act). If the protrusion of components cannot be avoided, they are to be covered up and clearly identified. Safety devices must also be attached to identify the dimensions of the vehicle and load and also to give due warning to other vehicles approaching from the rear – e.g. red-and-white striped warning signs 423 x 423 mm (DIN 11030; each stripe 100 mm wide, at an angle of 45° running from outside edge downwards).

Extra lighting must also be employed if the load being towed blocks the rear lights of the tractor, or if required by weather conditions: e.g. at front and back if the implement protrudes laterally more than 40 cm relative to the tractor’s own lighting; or rear warning lights in the case of an overhang of more than 1 m between the tractor tail lights and the end of the load being towed. Implements with transport wheel (jockey wheel – ”semi-mounted implement”) must be fitted with rear red lights and amber side position lights, which must always be available for use - even by day. (Additional warning lights are required if the load overhang is more than 400 mm relative to the tractor’s own lighting.)

We recommend you to order the required warning notices and lighting systems directly.

RABE can also supply bolt-on fixing brackets for DIN 11 027 lighting units.
