GENERAL OPERATION
Operation - 37
Front Auxiliary Couplers
CAUTION
Dirt and other debris in the hydraulic system can
cause damage to the system. Wipe the mating parts
of the couplers clean before attaching the hoses to
the hydraulic couplers. Install the dust plugs in the
hydraulic couplers when not in use.
If the attachment requires auxiliary hydraulics, couple
the attachment hoses with the front auxiliary cou-
plers. This is done by sliding the collar on the coupler
rearward, inserting the male coupler of the attach-
ment hose into the coupler, and then releasing the
collar. If the collar will not snap forward on its own,
pull it forward manually.
The couplers that the hoses are attached to will aect
the direction the secondary SDLA lever is moved to
control the action of the attachment. If the attach-
ment is equipped with colored indicators, connect the
hoses to the quick couplers so the colored indicators
are paired together.
The auxiliary couplers are controlled by moving the
secondary SDLA lever to the left or right.
NOTE: pressure build-up in the attachment hoses and
the power unit couplers may occur, causing dicult
installation of the hoses. If the hoses do not easily
connect, try one or both of the following steps.
1. To release pressure from the power unit couplers,
shut o the engine and move the secondary SDLA
lever to the left and right to release pressure in
the power unit’s hydraulic circuit.
2. To release pressure in the attachment hose,
loosen the hose end and retighten after the pres-
sure is released.
WARNING
Hydraulic uid is under high pressure and can pen-
etrate skin causing injury. Keep your hands, face,
and body away from pinholes or nozzles that can
eject hydraulic uid under high pressure.
Weight Transfer
The weight transfer system transfers weight from
the attachment to the front wheels of the power unit
when the front hitch is in oat or assists in lifting the
attachment. The operator can select dierent weight
transfer rates using the weight transfer select lever.
To set the weight transfer, raise the front hitch to its
maximum height and move the weight transfer select
lever to the desired position.
Selecting the proper amount of weight to transfer de-
pends on the attachment, the ground conditions, and
operator preference. A lightweight attachment (e.g.
KA160 power blower) will not operate in oat with
full weight transfer on. With full weight transfer on
and mowing in the oat position, the mower may not
lower quickly enough when mowing through uneven
terrain. The power unit speed or the weight transfer
rate must be reduced.
