The hydraulic lift system provides accurate,
smooth, and instant hydraulic power for raising a
variety of compatible equipment whenever the
engine is running. The system’s position control
feature maintains the selected height or depth of
three-point linkage equipment in relation to the
tractor. When the hydraulic lift control lever is
moved to a higher or lower setting in the
quadrant, the system repositions the equipment
to a higher or lower position and maintains the
selected position.
The hydraulic lift system is equipped with draft
control.
WARNING
Make sure the area is clear of people before
lowering equipment.
POSITION CONTROL
Position control provides easy, accurate control
of three-point linkage equipment which operates
above the ground, such as sprayers, rakes,
mowers, etc. It also provides uniform depth when
using a blade or similar equipment on ground
level.
When operating in position control, there is a
definite relationship between the position of the
control lever in the quadrant and the position of
the equipment. The lever
① , must be moved to
change the position of the equipment relative to
the tractor. The system will automatically
maintain the equipment in the selected position.
