– Never tow the tractor faster than following

speed.

Towing speed

10 km/h
(6.2 mph)

5. Directions for use of the power

steering

• The power steering is activated only while the

engine is running. While the engine is stopped, the
tractor functions in the same manner as tractors
without power steering.

• Turning the steering wheel all the way to the stop

activates the relief valve. Do not hold the steering
wheel in the stop for a long period of time.

• Avoid turning the steering wheel while the tractor is

stopped, or tires may wear out sooner.

• The power-steering-mechanism makes the steering

easier. Be careful when driving on a road at high
speeds.
