Hydraulic Power Lift (Hpl) - Roll Over Protective Structure (Rops) - New Holland Boomer 45 Operator's Manual

Hydraulic Power Lift (HPL) - Roll Over Protective Structure (ROPS)

The HPL lever (1) is located on the right-hand control pod.
The lever controls the position of the two lift arms.
DANGER
Crushing hazard!
Make sure area is clear of all persons before
lowering equipment.
Failure to comply will result in death or serious
injury.
To lower the lift arms, first make sure the drop rate con-
trol valve (2) is open, and then move the HPL lever (1)
forward. To raise the lift arms, move the lever rearward.
An adjustable lower stop (3) is located in this quadrant
for returning the lever to a preset lowering position of the
hitch. An adjustable upper HPL control lever height stop
(4) prevents the control lever from exceeding the lift limit
and causing the tractor hydraulic system to go over the
relief valve setting.
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 operator moves the hydraulic lift con-
trol lever to a higher or lower setting in the quadrant, the
system repositions the equipment to a higher or lower po-
sition and maintains the selected position.
Position control
Position control provides easy, accurate control of the
three-point linkage equipment, which is operated 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 re-
lationship between the position of the control lever in the
quadrant and the position of the equipment. Move the
lever to change the position of the equipment relative to
the tractor. The system will automatically maintain the
equipment in the selected position.
