NOTE
：
For safety, the seat should not be adjusted while the tractor is in motion.
Never adjust the rigidity of seat so that it is too soft. This can cause problems when running the tractor on
uneven surfaces resulting in a possible accident.

Hydraulic Suspension, PTO, and Electrical System Operation
The Series 40XT and 50XT tractors use a semi-separate hydraulic lifting system with two types ofadjustment
modes: position adjustment and height adjustment. The control handle of the control distributor valve is used to
raise and lower farm implements. Push the handle forward to lower an implement; and pull it back to raise an
implement. See ―Hydraulic Lifting System Adjustment‖ for the adjusting to reach the maximum raising position
and for reaching the minimum lowering position.
2.16.1 Implement Position/Height Adjustment
When the tractor is pulling a cultivator or a plow, a 3-point lift is used to adjust the tilling depth. The tilling
depth is determined by the position of the lowering stopper in the reset push rod, which adjusts the height from
the ground level to the plow bottom. When adjusting the stop on the 3-point lift, set the stop to the lower limit,
and put the 3-point lift control handle in the low position. When the farm implement is lowered to the required
depth (the adjustment method is shown in the
Adjustment on the Hydraulic Lift System
section), it will
operate at the tilling depth.
NOTE
:
Adjust tilling depth (draft) control according to implement specifications.
2.16.2 Farm Implement Lowering Speed Adjustment
Select a suitable lowering speed for the farm implement to keep it from being damaged by heavy impact
when it contacts the ground. Before delivery of the tractor, the descending speed regulating valve was adjusted.
The owner/operator can readjust the valve according to the weight of farm implement and ground hardness.
To
decrease
the lowering speed of the farm implement, turn the adjustment valve (A) clockwise.
To increase the lowering speed of the farm implement turn the adjustment valve (A) counterclockwise.
