Implement tillage depth can be adjusted in two ways: force adjustment and position adjustment:
a) Draft adjustment
Draft adjustment is also known as resistance adjustment. The tillage depth is automatically controlled by variation
in implement resistance. Generally, force adjustment is used for tillage. Set the draft adjustment lever to the
Maximum Lift position. Move forward the force adjustment lever. The implement stops lowering at a proper tillage
depth due to the adjustment mechanism. The required tillage depth can be selected while the tractor is moving. The
more the force adjustment lever is moved forward, the more the implement lowers. The less the force adjustment
lever is moved forward, the less the implement lowers. After selecting the required tillage depth, move the force
adjustment lever locating device in place so that the force adjustment lever can always be moved to the same location
to ensure consistent tillage depth. In case of uneven terrain or considerable variation in soil resistance, the implement
tillage depth can be adjusted automatically.
If soil resistance increases, the implement slightly lifts to reduce tillage depth. If soil resistance decreases, the
implement lowers to increase tillage depth.
b) Position adjustment
Position adjustment refers to adjusting the position of implement relative to the tractor. Generally, position
adjustment is mainly used for rotary tillage, harvesting, sowing, and bulldozing. Position adjustment can be used
for tillage across even terrain.
When using the position adjustment work force adjustment handle in the first end of the raised position, the position
adjustment lever forward and drop implements. Each position of the position adjustment lever corresponds to a
position of the implement relative to the tractor. The more the position adjustment lever is moved forward, the more
the implement lowers. The required tillage depth can be selected while the tractor is moving. When the implement
reaches the required tillage depth, move the position adjustment lever locating device in place so that the position
adjustment lever can always be moved to the same location to ensure consistent tillage depth.
Adjusting the lowering speed of the implement
According to weight and type of the implement and hardness
of the ground, select a proper lowering speed of the implement
to avoid damage to the implement. By turning the lowering
speed adjusting handle

of the lifter in clockwise direction,
the lowering speed of the implement decreases; otherwise, the
lowering speed of the implement increases.
