POWER STEERING
• Pay attention to the steering wheel while
driving, because it can be very lightly ma-
nipulated when the engine is running.
• Power steering will run only when engine
is running. When engine is idling, power
steering may feel a little heavy.
• If the wheel is steered to the maximum,
the relief valve is opened and a warn-
ing sound will be made. Do not continue
to operate the tractor with the warning
sound.
• Do not steer the wheel unnecessarily,
because steering the wheel without mov-
ing will attribute to early wear of tires and
rims.
