Overviews
This tractor has the full hydraulic, non-load reaction
type steering system.
The full hydraulic type completely relies on the hydrau-
lic oil for transferring the power between the steering
unit and the steering cylinder. It is not equipped with
any mechanical transferring system, such as a drag
link, pitman arm, rack or pinion. Therefore, the angles
of the steering wheel and the front wheels are not xed
each other.

The connection of the section (A) distinguishes the load
reaction and the non-load reaction.
For the load reaction type, when one steering cylinder
is compressed by the outer force applied to the front
wheel while driving, the returned oil turns the gerotor of
the steering unit which then turns the steering wheel.
Then, the oil ows to the other cylinder.

Therefore, when releasing the steering wheel after cor-
nering, the steering wheel is automatically returned to
the center position and the tractor moves straight for-
ward or backward. This is convenient for the high-speed
driving, but the steering wheel should be held to keep
the steering angle and the noise and vibration is severe
than the non-load reaction type. Therefore, this tractor
is equipped with the non-load reaction type to enhance
the operational convenience and minimize the noise
and vibration.
