Mountfield 4155H, 4135H, 4155 H 4WD manual Description

ENGLISHEN

The seat can be folded. If the machine is parked outside when it is raining, fold the seat forward to protect the seat cushion from getting wet.

The seat is locked. To fold the seat up or down, re- lease the catch (S).

4.5 Steering wheel

See fig. 7. In order to minimise the axial play in the steering column, the shim washers (D) and/or (E) must be installed on the steering column between the steering column jacket and the bracket as fol- lows.

1.Install the steering column jacket on the steer- ing column and secure by knocking in the ten- sion pin (C) approximately 1/3 of its length.

2.Pull the steering column jacket and the steering column up.

3.From the outside, check whether no washers, the 0.5 mm washer, the 1.0 mm washer or both washers can be inserted into the gap. The wash- er/washers must not be forced in, as there must be a little axial play.

4.Pull out the cotter pin and dismantle the steering wheel jacket.

5.Install the washer/washers in accordance with point 3 above.

6.Install the steering column jacket on the steer- ing column and secure by knocking in the ten- sion pin fully. Use a counterhold.

4.6 Towing hitch

See fig. 8. Screw the towing hitch (J) into the two holes on the underside of the rear axle using screws (L+K). Tighten the screws properly.

Tightening torque: 22 Nm.

4.7 Deck mounts

This only describes installation on the right-hand axle. Same procedure must be carried out on the left-hand axle.

1.Lubricate the axle ends and the deck mount’s bearing surface with oil before installation.

2.Install the deck mounts to the machine accord- ing to fig. 9.

3.Install the locking pin (9:Q) in the hole in the axle.

5.1Transmission

5.1.1 HST

The machine is rear wheel drive.

The rear axle is equipped with a hydrostatic trans- mission with infinitely variable forward and re- verse gear ratios.

The rear axle is also equipped with a differential to facilitate turning.

Front mounted tools are driven by drive belts.

5.1.2 4WD

The machine has 4-wheel drive. The power from the engine to the drive wheels is transferred hy- draulically. The engine drives an oil pump, which pumps oil through the rear and front axle drives. The front axle and rear axle are connected in se- ries, which means that the front wheels and rear wheels are forced to rotate at the same speed.

To make turning easier, both axles are equipped with differential.

Front-mounted implements are powered via drive belts.

5.2Steering

The machine is articulated. This means that the chassis is divided into a front and a rear section, which can be turned in relation to each other.

The articulated steering means that the machine can turn around trees and other obstacles with an extremely small turning radius.

5.3Safety system

The machine is equipped with an electrical safety system. The safety system interrupts certain activ- ities that can entail a danger of incorrect manoeu- vres. For example, the engine cannot be started if the clutch-parking brake pedal is depressed.

The operation of the safety system must always be checked every time before use.

4.8 Tyre pressure

Check the air pressure in the tyres. Correct air pressure:

Front: 0.6 bar (9 psi)

Rear: 0.4 bar (6 psi)

4.9 Accessories

For the installation of accessories, see separate in- stallation guide supplied with each accessory. Note: The cutting deck is regarded as an accessory here.

5.4 Controls

5.4.1 Implement lifter, mechanical (12:A)

To switch between working position and transport position:

1.Depress the pedal fully.

2.Release the pedal slowly.
