FINAL DRIVES

The front final drives transmit power to the front wheels through bevel gear pairs. This kind of final drives gives a high clearance from the ground, ideal for low crops.The final drives are water and dust tight.

High ground clearance - Perfectly dust and water tight front axle.

FRONT MUDGUARDS (option)

Front turnable mudguards are available on request, so that the steering radius is not reduced when handling the trac-tor in tight spaces.

STEERING STOPS

When adopting minimum tracks, the front wheels may interfere with the tractor engine housing and thus two fixed stops are provided as a limitation to the maximum steering angle.

HYDRAULIC CIRCUITS

Two hydraulic gear pumps powered directly by the gears of the timing system with 1 paper filter on the common intake.

The two pumps feed 2 separate circuits:

1st pump: Flow rate 18.7 litres/min with engine at top rated speed.It supplies:• The power steering circuit, max. operating pressure 110 +/-5 bar.• Low pressure circuit (17-18 bar) of differential lock.

2nd pump: Flow rate 27 litres/min with engine at top rated speed.It supplies:• The auxiliary control valves, max. operating pressure 180 +/- 5 bar.• The hydraulic power lift, max. operating pressure 180 +/- 10 bar.

Two independent circuits with two hydraulic pumps giving the max. possible flow rate to handle the tractor and the connected implements.

The externally mounted pumps (1) and filter(2) allow a quick service.

Only one type of oil: less costs and easy service.

Independent circuits: top performances.Shorter machine down times for service.

AUXILIARY CONTROL VALVES

Open-center auxiliary control valves with rear quick 'Push-Pull' attachments.

The control levers (A+B+C) are places at the right of the driver's seat and have the same colour as the rear hydrau-lic taps (1+2+3) to make identification easier for coupling and controlling the hydraulic implements.

Available versions:• Basic version: 4 rear ways controlled by two standard control valves convertible from single to double acting.

• Optional version: rear 6-ways controlled by two standard control valves and 1 floating control valve convertible from single to double acting.

The auxiliary control valves use the hydraulic power lift pump: the max. operating pressure is thus 180 bar like the power lift.

Top flexibility to suit the tractor to different ap-plications.

Basic version: 4 rear ways (only A+B)

Optional version: 6 rear ways (A+B+C)

MECHANICALLY CONTROLLED POWER LIFT

Controls on the right-hand side of the driver's seat, in a suitable position for work control.

By the two levers, the following operation modes can be selected:

- position control,for implements operating over ground

- draft control, for tillage implements (the lugging power is maintained at a constant level varying the work depth).

- mixed position and draft control. The Intermix mode (mixed position-draft control) is useful on irregular soil. With this control mode, the power lift operates in the draft control mode, but meanwhile prevents the imple-ment from digging excessively into softer soil and pro-ducing an uneven job.

- float mode (used with implements that rest on the ground).

Each of these modes must be chosen according to the type of work in hand, the type of implement and the con-sistency of the soil.

In the above mentioned operation modes, further adjust-ments of sensitivity and lowering speed of the implements improve the work carried out.

Lever functions:1. Position control lever.2. Draft control lever.3. Lever position stops.

Excellent and complete system to control power lift functions.

User friendly, easy to adjust.
