Top Link Adjustment; Hydraulic Power Lift (Hpl) Drop Rate Control Valve - New Holland Boomer 45 Operator's Manual

Top link adjustment

The three point hitch top link attachment point (1) has two
holes for attaching the upper link. Attach the link using the
lower hole for 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 raise to maximum
height but cannot lower.
NOTE: Adjust the drop rate control valve needs accord-
ingly to the amount of weight being carried on the rear
hitch arms.
