3 - CONTROLS AND INSTRUMENTS
Rearward controls
Hydraulic Power Lift (HPL) drop rate control valve
The location of the three-point hitch drop rate control valve
(1) is below the operator’s seat.
The drop rate control valve (1) provides an adjustment to
regulate the flow of oil from the lift cylinder. This allows the
operator to slow or increase the rate of drop of the lower
links.
Turn the drop rate control valve clockwise to decrease the
rate of drop. Turn the valve counterclockwise to increase
the rate of drop.
The drop rate control valve must be opened before the
hydraulic lift control will lower. If the valve is turned all the
way clockwise, the lower links raise to maximum height
but cannot lower.
For most operations using a heavy mounted implement
the drop rate control valve should be closed slightly to
maintain better control when lowering the implement.
For three-point hitch operating instructions see page 6-9 .
