Operation Description

NOTE
：
1. For safety, the seat should not be adjusted when the tractor is in motion.
2. Making the seat too soft can make running the tractor on uneven surfaces particularly challenging and cause a
loss of sight lines.
2.15 Hydraulic Suspension, PTO, and Electrical System Operation
The Series 70XTC tractor uses a semi-separate hydraulic lifting system with two types of adjustment 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 adjustments to reach the maximum raising position and 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.
