2.16.1 Operation of hydraulic raiser
Raiser of this series of tractor is of push-in-soil type, has the advantages of simple structure
and strong practicability. The multi-way valve handle at the right side of the driver is the operation
handle of the raiser.

When the operation handle is turned to the forepart
from the 'neutral' position (obviously feel that the
operation handle is orientated), the suspension
mechanism starts to rise; when it rise to the terminal,
the operation handle automatically resets (go back
to the neutral position);

When the operation handle is held and turned
backward from the 'neutral' position (at this time the
operation is not at the final position), the suspension
mechanism start to drop, at this time, if the operation
handle is loosen, the operation handle will timely
rebound to 'neutral' position, and the dropping will
stop.

When the operation handle is turned from the 'neutral' position to the final position
(obviously feel the operation handle is orientated), the suspension mechanism is at 'float'
condition after dropping to the final position.
2.16.2 Operation and use of hydraulic output device
One group of hydraulic output can be selected for this series of tractors according to the
necessity. The hydraulic output is provided with two quick-change coupler male connectors; when
it is not used, it shall be covered well by sealed cap. When using, connect the backup female
connector (put in the spare part case) and the male connector of the quick-change coupler and
then communicate it with the oil inlet and oil outlet of the oil cylinder of hydraulic agricultural
machinery. The hydraulic operation handle (on the multi-way valve assembly which is at the right
side of the driver and is close to the right splash guard) controls the hydraulic output. The hydraulic
output valve can achieve single action hydraulic output and double action hydraulic output through
squashing in and squashing out the single action and double action transforming bolt which is
arranged on the multi-way valve. Withershins twist to looser and exit the bolt can achieve hydraulic
output of single action; on the contrary, to totally twist the bolt in can achieve double action
