SOFT-RIDE LOADER SUSPENSION
SYSTEM (OPTION)
CAUTION
Always lower the loader to the ground before
activating/deactivating the “Soft-Ride” function.
Description
This option dampens the vertical movements of the
loader when driving on uneven ground. It consists of
one or two accumulators, depending on loader
model.
Soft-Ride can be engaged during most tasks, but can
be disengaged when precision operation with exact
control of the loader is required.
NOTE: The accumulators, 1, used with the Soft-Ride
system are pre-charged and can not be re-charged.
Contact your dealer for service.
Soft-Ride function can be shut off completely or
engaged in two working modes with a knob (2) as
desired.
Position I = Shut Off
Position II = Accumulators open to the lift side of the
cylinders (+).
Position III = Accumulators open to the lift side of the
cylinder (+) and the rod side of the cylinder (--).
In position III, there is an internal relief port from the
(--) rod side to the (+) side of the lift cylinder. When in
position III you cannot maintain down pressure on
the cylinders with the joystick in its neutral position.
Positions I, II, III can only be selected when the
pressure has been relieved from the system. Lower
the loader to the ground and shut off tractor engine.
Move the joystick control lever to all control positions
and return to neutral.
NOTE: When using attachments which require a
double acting cylinder function, use positions I or II.
