DRIVE OF AGRICULTURAL MACHINERY

Engaging Rear Pto Shaft

The number of PTO shaft revolutions is dependent on the number of engine revolutions

With engine running:

1. Select applicable operation mode by standard and economic PTO shaft revolutions preselection lever.

2. Select applicable revolutions by switch of selection of rear PTO shaft (2) revolutions

3. Rear PTO shaft is set into operation by switching the switch of rear PTO shaft (3)

If the aggregated machine allows it, engage the rear PTO shaft with minimum revolutions of 1500 rpm.

Front Pto Shaft

Front PTO shaft is equipped with a solid six or twenty-one splined end point and it comes only in design of 1000 revolutions.

Tractor may be equipped with front PTO shaft with varied direction of spinning: a - In compliance with the direction of engine revolutions (standard) b - Against the direction of engine revolutions (∗ on request)

Front Pto Shaft Control

Engagement and disengagement of front PTO shaft is done by a switch (1) placed on the right column of the cabin. The switch is equipped with a mechanical lock (2) against unwanted switch. When switching the switch depress the lock in the downward direction.

If the aggregated machine permits, engage front PTO shaft with min. engine revolutions of 1500 rpm.

DRIVE OF MACHINES WITH GREATER INERTIA MASSES (CRUSHERS, ROTARY HARROWS, REAPING MACHINES.)

Cardan shaft for drive of these machines must be equipped with the so called freewheel clutch which ensures disconnection of torque transfer with retroaction from the machine on the tractor.

HYDRAULIC SYSTEM

The system consists of the inner and outer circuit.

The source of pressurized oil is a gear pump.

Oil is drawn from the common filling of the gearbox and final drive housing.
