light draft loads, such as mowers. Attach the link to the
top hole for heavier draft loads, such as ground engaging
equipment.

Hydraulic Power Lift (HPL) drop rate control valve
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 "IN" (clockwise) to de-
crease the rate of drop. Turn the valve "OUT" (counter-
clockwise) 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 "IN" (clockwise), the lower links can be raised to
maximum height but cannot be lowered.
NOTE: The drop rate control valve needs to be adjusted
accordingly to the amount of weight being carried on the
rear hitch arms.
