HYDRAULIC LIFT ROCKER
The hydraulic lift rocker has two holes for
attaching the upper link. Attach the link using the
lower hole
①
for light draft loads, such as
mowers. Attach the link to the top hole
②
for
heavier draft loads, such as ground engaging
equipment.
NOTE:
Remove the lock pin
③
, for the draft
control linkage to be operative.
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 decrease 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.
