General safety tips for using the
trailer

Tips for travelling with the trailer

The handling of the tractor is influenced by the trailer
coupled to it.

• Danger of tipping exists when working on slopes.

• The driving must be adapted

to the corresponding terrain
and ground conditions.

• The towing vehicle is to be
sufficiently equiped with
weights at the front or at the
rear in order to guarantee the
steering and braking capacity
(a minimum of 20% of the
vehicle's tare weight on the
front axle).

• The transport of persons on the machine is not permitted.

Tips for coupling and uncoupling the trailer

• Danger of injury exists when coupling the implement to the
tractor!

• As long as the tractor is moving backwards, do not step
between it and the trailer when coupling.

• Nobody is to stand between the tractor and trailer without
the vehicles being secured against
rolling with the parking brake and/or
wheel chocks.

• Drive shaft connection or
disconnection is only to be undertaken
when the motor has stopped.

Parking the implement

• When the implement ist parked, either
remove the driveshaft and store it, or
secure it with a chain.

Do not use retaining chain (H) for this.

Only use the trailer according to regulations!

Regulations for Use: See chapter "Technical Data".

• The trailer's load limits (permitted axle load, support load,
total weight) may not be exceeded. The relevant details
are located on the right side of the trailer.

• In addition, observe the power limits of the tractor being
used.

Travelling on roads

• Observe the road rules.

• The tailgate must be closed when travelling on public

roads. Lighting devices must be fitted vertically to the road.

PIVOTING DRAWBAR

GB

Adjusting drawbar to tractor’s towing coupler

To allow pick-up to work perfectly, the height (M) of coupled trailer must be correctly set
(pick-up pivoting area).

Height (M) = 43 cm
Note: Where the floor is uneven, reduce the measurement by 1 cm (M = 42 cm).

- Park unloaded trailer on even ground
and on jockey wheel.

- Attach trailer coupler (A) to tractor so that
on towed vehicle adequate distance exists
between drive shaft and drawbar.

- Set height (M) from ground to centre of
feeler coupling point by adjusting jockey
wheel.

Drawbar adjustment when equipped with adjusting spindle:

- Loosen lock-nuts (K).

- Twist turnbuckle barrel (V) correspondingly.

- Check height (M) of trailer coupled to tractor.

Observe following when equipped with

hydraulic cylinder:

- Couple trailer to tractor.

- The hydraulic cylinder piston must be
completely inserted.

- Twist nut (51) until clamp frame (52) is at
rightangles (about 90°) to slip rod (G). The
clamp can then be raised.

A slot is located in the fork of the regulating spindle.

- The fastening bolt (56) must make contact with the
inside of the slot.

- Loosen lock-nut (K) on the threaded spindle.

- By twisting the cylinder piston (50), screw the threaded
spindle in or out until the height (M) is achieved.

Slip rod (G) must be able to move in the casing during
the adjustment process (adjust with nut 51).

- Retighten lock-nut (K).

- Twist nut (51) until clamp frame (52) is at rightangles (90°) to slip rod (G).

Pivoting drawbar safety device check

Function of the automatic clamping device:

It prevents the trailer from tipping up during the return trip.

- Adjust by twisting the nut (51) until the clamp frame (52) prevents the trailer from
tipping up through a slight inclination of the slip rod (G).

Maintenance:

Grease pivoting drawbar safety device frequently!

Initial operation

With initial operation install accompanying catch bracket (12) onto mudguard so that
it is within reach and can be seen.

Insert moveable hand break lever (13) onto tractor for every run.

- Carry out brake test.

Attention!
If brake fault occurs, immediately stop tractor and clear fault.

Should the adjustment action on the hand
brake lever no longer be adequate, then with
the help of the notches on the brake cam axle
lever, alter the position of the lever (19)
correspondingly.

The lever adjustment (19) must be
carried out on both sides
simultaneously.

Adaption to tractor

- Loosen cable clamps (1) and unthread the cable through the support (2).

- Shorten bowden cable covering (see diagram) to a point where trouble-free cornering is still is possible.

- Rethread cable and secure with cable clamps.

- Check lever action (B) and adjust with
hexagonal nut (3) if necessary.

Shortening the bowden cable

The extra long brake cable is manufactured to suit
the various designs of different tractor types.

In order to guarantee optimal function of brake
unit, the cable (A) should run in a straight line if
possible.

Brake adjustment

- If brake linings are worn out then brake shoes must be adjusted. This is carried out by turning adjusting nut (3) on hand brake lever.

HYDRAULIC OPERATION

537 / HYDR.KAB.BED. 9501 GB

GB

Standard position: with an open hydraulic

system

• e.g. a standard tractor with a gear pump.

- The standard basic setting for the shut-off valve (position A)
applies to this type. In this position the shut-off valve is open.

Tip! If the tractor has a closed hydraulic system and the unit

is operating in this position, then the hydraulic oil will heat up
(particularly due to the constant pumping of the maximum
amount of oil).

Remedy: Modify the system on the trailer or decrease the

amount of oil being pumped at the tractor as written below.

Take care! with tractors with a closed hydraulic

system

• JOHN-DEERE, FORD Serie 40 SLE
CASE-MAGNUM, CASE-MAXXUM,

1. Close the shut-off valve (position B).

2. Dismount lever (7) and fit onto the shut-off valve (11).

Hydraulic connection

Single-action control unit

Should the tractor only have a single-action servo-valve,
then it is absolutely necessary to have an oil-return pipe (T)
fitted by a specialist.

- Connect pressure hose (1) to the single-action control unit.
Couple the oil-return hose (2) (with the greater diameter) to
the tractor’s oil-return system.

Double-action control unit

Please take particular care when the operating
elements on the trailer and the tractor are to be used
simultaneously by more than one person. A
conscientious arrangement should be made by those
concerned before operation.

An example:

Danger of injury arises if a person stands at the rear of the
trailer and somebody in the tractor cabin activates a switching
function (opening the tailgate, switch on the driving gear, ...).

Mounting bracket

• The accompanying bracket (L) is for mounting the hydraulic
switching element in the cabin and is to be installed on the
tractor's mud guard.

Operating elements

• Depending on the trailer's fittings, the order of the operating
elements can differ slightly to the representation shown. For
example, the lever with positions "E1-A-E2" can only be
used on trailers with all extras (e.g. hydraulic drawbar,
hydraulic dry forage extension, tailgate).

The following operating instructions refer to trailers
with all extras

• Shift lever "6" serves to reverse the hydraulic flow between
the the oil cycle of the hydraulic scraper floor drive and the
oil cycle of the preselection levers for the Pick-up lift,
drawbar, etc..

ST = Control valve
0 = 0-position

I + A = Pick-up (9), hydraulic drawbar (10)

II = Hydraulic scraper floor drive
I + E2 = Tail gate
I + E1 = Dry forage extension

P = Pressure hose

T = Runback hose

Obstructions when swivelling

- Remove foreign body from swivel range.

• If the cutter bars do not swivel in properly, then a pressure
loss in the cutter unit hydraulic could be the cause.

Remedy by hydraulically filling the reservoir

1. Move lever to position "E" on 3-way valve.

2. Actuate servo-valve. The cutter bar is swivelled out
hydraulically.

3. Leave servo-valve (ST) in the press position for a few
seconds while moving the lever on the 3-way valve to
position "0".

• If obstruction cannot be removed then check gas fill pressure
(100 bar nitrogen) in hydroreservoir.

Alteration of gas container pressure

• This work may only be carried out by customer service or a

specialist.

• In order to reduce or increase the pressure in the gas

container a special filling and checking device is necessary.

Note

• According to manufacturer's information all gas containers

have a slight pressure drop after a certain amount of time.

• The gas loss (nitrogen) amounts to 2-3 % per year.

• After 4-5 years it is recommended that container pressure be

checked and if necessary corrected.

Maintenance

Beware!
No welding, soldering or mechanical works of any
kind may be carried out on the container.

• Hydraulic oil change according to tractor manual.

Dry forage extension

1. Lever (W) in position "DA".

2. Lever on control panel in position "E1".

3. Engage servo-control (ST) on tractor.
Folding extension up or back gradually.

Swivelling cutter unit

Caution!
Do not reach into swivel range of cutter bar

when swivelling in / out.

1. Lever (W) in position "SW".

2. Lever on control panel in position "E1".

3. Engage servo-control (ST) on tractor.
Both cutter bars swivel in resp. out.

• When only one cutter bar is needed for mowing, the lower
cutter bar can be swivelled out using the accompanying
lever (H).

Operation errors

In the operation errors which follow, a problem can arise with the coupling and/
or uncoupling of the hydraulic hoses.

Operation error no. 1

- Pressure hose (P) and runback hose (T) coupled. CORRECT !

- Selector valve (9) open for pick-up operation. CORRECT !

- Lever switch (6) into position I. CORRECT !

- Pick-up in raised condition. WRONG !!!

Result:

Due to the dead weight of the pick-up, pressure builds up in the hydraulic hose
(P). To uncouple the pressure hose is only possible with great effort.

Solution:

Put lever switch (6) into the "0"-position for reoperation. The pressure in the
hydraulic hose can be eased by opening a screw connection.

Caution!
Close the selector valve (9) for pick-up operation before uncoupling and
bring the control valve (S) into "lower" or "float" position.

Operation error no. 2

The wagon with hydraulic drawbar is coupled to the tractor and the jockey
wheel is cranked up.

- Pressure hose (P) and runback hose (T) coupled. CORRECT !

- Selector valve (10) opened for hydraulic drawbar operation. CORRECT !

- Lever switch (6) to pick-up operation (position I). CORRECT !

- The hydraulic drawbar cylinder is not quite retracted

before garaging the wagon. WRONG !!!

Result:

Because of the load resting on the cylinders, excess pressure builds up in the
hydraulic hose (P). Uncoupling of the hose is not possible.

Solution:

Completely retract the hydraulic drawbar cylinder or garage the wagon on the
jockey wheel so that the load on the cylinder is eased.

Caution!
Do not operate the hydraulic drawbar while the wagon is supported on the
jockey wheel.

Hydraulic connection

Single-action control unit

Should the tractor only have a single-action servo-valve,
then it is absolutely necessary to have an oil-return pipe (T)
fitted by a specialist.

- Connect pressure hose (1)

to the single-action control
unit.

- Couple the oil-return hose

(2) (with the greater
diameter) to the tractor’s
oil-return system.

Double-action control unit

- Connect pressure line (1) and oil-return pipe (2) (pipe with

the greater diameter is the oil-return pipe).

Note:

If oil should become warm during operation then a single­action control unit should be connected (see above).

Power supply

• Power (8) 12V is supplied via relay (9) connected to the

ignition (10).

• Lead diameter 2,5 mm2, fuse 16A (11).

• Power for the trailer is supplied via socket "54g" (+pole) and

"31" (-pole).

This modification is to be carried out only by
specialized workshops.

• Don’t connect directly to ignition (danger of fire and/or
damage of electrical equipment).

Establishing electric connection

- After completing above mentionnned work connect 7-pole
plug from trailer with socket.

- Check lights.

Standard position: with an open hydraulic

system

• e.g. a standard tractor with a gear pump.

- The standard basic setting for the shut-off valve (position A)
applies to this type. In this position the shut-off valve is open.

Tip! If the tractor has a closed hydraulic system and the unit

is operating in this position, then the hydraulic oil will heat up
(particularly due to the constant pumping of the maximum
amount of oil).

Remedy: Modify the system on the trailer or decrease the

amount of oil being pumped at the tractor as written below.

Take care! with tractors with a closed hydraulic

system

• JOHN-DEERE, FORD Serie 40 SLE
CASE-MAGNUM, CASE-MAXXUM,

- Close the shut-off valve (position B).

- Dismount lever (7) and fit onto the shut-off valve (11).
