Driving on slopes

iving on slopes is one of the operations where the risk of the driver losing control of the machine or of it overturning is the greatest; this can result in serious injury or death. All slopes demand extra care. If you cannot reverse up a slope or if you feel unsure, do not mow it.

IMPORTANT INFORMATION

Do not drive down slopes with the unit raised.

• Do not make any sudden changes in speed or direction.

• Avoid unnecessary turns on slopes, if necessary, turn slowly and gradually downwards if possible. Drive slowly. Do not turn the wheel sharply.

• Watch out for and avoid driving over furrows, holes and bumps. It is easier for the machine to overturn on uneven ground. Tall grass can hide obstacles.

• Do not mow too close to edges, ditches or banks. The machine can suddenly overturn if one wheel comes over the edge of a steep slope or a ditch, or if an edge gives way.

• Do not mow wet grass. It is slippery, and tyres can lose their grip so that the machine skids.

• Do not try to stabilize the machine by putting your foot on the ground.

• When cleaning the chassis, the machine may never be driven near verges or ditches.

• When mowing, keep away from bushes and other objects.

• Follow the manufacturer’s recommendations regarding wheel weights or counterbalance weights to increase machine stability.

PRESENTATION

Presentation

Congratulations on your choice of an excellent quality product that will give you great pleasure for many years. This operator’s manual describes P 520D and P 525D.

P 520D and P 525D are equipped with hydraulic steering and an equipment hoist.

The machines are equipped with four wheel drive.

The power transmission from the engine is handled by a hydrostatic transmission, which allows variable variation of the speed by using the pedals. One pedal for driving forward and one for reverse.

Counter

The chronometer shows how many hours the engine has been running.

Any time when the engine is not running but the ignition is switched on is not registered. The last digit shows tenths of an hour (6 minutes).

Parking brake

Operate the parking brake by moving the handle forwards.

Throttle trigger

The throttle control regulates the engine speed, and thereby also the rotation speed of the blades.

To increase or reduce the engine speed the control is moved forwards or backwards.

When driving the throttle control must be in the position for maximum engine speed, work mode.

Speed limiter

The speed of the machine is steplessly regulated with two pedals. Pedal (1) is used to drive forwards, and pedal (2) to drive backwards.

Cutting unit

P 520D and P 525D can be equipped with two different cutting units.

• Combi 132

• Combi 155

The Combi-unit, equipped with a BioClip-plug, ﬁnely chops the cuttings to fertiliser. Without the BioClip-plug the unit works in the same way as a rear ejection unit. The rear ejector ejects the clippings behind the unit without ﬁnely chopping them.

12 – English

WARNING! Make sure that branches do not obstruct the pedals when mowing under bushes. Otherwise there is a risk you may lose control.

PRESENTATION

Adjusting the cutting height

The cutting height can be adjusted to seven different positions.

Select the required cutting height (1-7) using the cutting height adjusters. Set the knobs horizontally so that they do not snag on bushes and the like.

Lever for hydraulic lift of attachments

The lifting lever is used to put the cutting unit in either the transport or mowing position when hydraulic pressure is available.

The lever has four different positions.

Pull the lever backwards to engage the transport position. The unit is then raised.

The cutting unit can be raised slightly with the blades rotating. This is to facilitate the mowing of extremely tall grass or uneven surfaces.

Lowering the Unit (Mowing Position)

Move the hydraulic lifting lever forwards to engage the cutting position.

When cutting the lever should be set directly to the ﬂoating position (3).

• Position 1 is the neutral position.

• Position 2 lowers the cutting unit with spring return to the neutral position

• Position 3 is ﬂoating where the lever stops. The unit is lowered to the automatically ﬂoating position, which means that the cutting unit follows the contours of the ground.

• Position 4 raises the cutting unit with spring return to neutral position.

When cutting the lever should be set directly to the ﬂoating position (3).

Lifting the Cutting Unit (Transport Position)

Stop the blades by pressing the stop button.

Controls for operating the cutting unit blades

The cutting unit can be started only when the driver is sitting in the seat.

• Pull out the lever to engage the drive of the blades.

• Push in the lever to disengage the blades.

When the safety circuit has stopped the drive to the cutting unit, the control must be pushed and pulled out again to start the blades.

The safety circuit is triggered and the cutting unit is stopped in the following cases:

• When the driver leaves the seat with the blades engaged. There is a short delay to prevent stopping if the driver bounces on the seat.

Starting and driving when cold

If the engine fails to start due to the cold, repeat ignition and attempt to re-start. Start gas or ether must not be used.

IMPORTANT! At temperatures below 0 ° C, the machine must be warmed up for at least 10 minutes for the hydraulic oil and transmission to get hot. Otherwise there is a risk of the transmission breaking down thereby reducing the service life of the transmission.

Winter fuel

When driving in very cold weather operating problems due to parafﬁn precipitation can occur if you run on standard fuel. To counteract this, winter fuel is sold in the climate areas affected. In some regions, different fuel is sold in summer and winter. Ask your fuel supplier and use only winter fuel below 0°C (+32°F).
