GENERAL OPERATION
Operation - 23
depends on attachments, ground conditions, and
operator preference. A lightweight attachment (e.g.
LA162 Power Blower) will not go down with full weight
transfer on. With full weight transfer on and mowing
in the fl oat position, the mower may not come down
quickly enough when going through dips. Weight
transfer must be reduced or speed must be lowered.

Pulley
Pulley
If the attachment requires a drive belt, then release
the tension from the attachment drive belt and
loop the belt around the drive pulley at the location
shown in the fi gure above. When belt is in place
around the bottom drive pulley, tension the belt of
the attachment.
Engage the PTO by pulling up on the PTO switch on
the control panel. Note: PTO will engage only if the
operator is present on the seat.
Front Auxiliary Couplers
If the attachment requires auxiliary hydraulics, couple
the attachment hoses with the front auxiliary couplers.
This is done by sliding the collar of the coupler rear-
ward, inserting the end of the attachment hose into
the coupler and releasing the collar. If the collar will
not snap forward on its own, pull it forward manually.
Dirt and other debris in the hydraulic system can
cause damage to the system. Wipe clean the
mating parts of the couplers before coupling. Use
protective rubber plugs over power unit couplers
when not in use.
If equipped, connect the hoses and quick couplers
so the red indicators are paired together and the
yellow indicators are paired together. If the power
unit or attachment is not equipped with red and
yellow indicators, connect the hoses and quick
couplers and test the action of the attachment. If the
action is not the desired motion, switch the hoses
that the couplers are attached to. Auxiliary valves
are controlled by moving the secondary S.D.L.A.
lever left or right.
NOTE: pressure buildup in the attachment hose
and on the power unit couplers may occur causing
diffi cult installation of hoses. If hoses do not easily
connect, try one or both of the following steps.
1. To release the pressure from the power unit cou-
plers, turn off engine and move the secondary
S.D.L.A. lever right and left to release pressure
in the power unit hydraulic circuit.
2. To release pressure in the attachment hose,
loosen one of the hose ends and retighten after
the pressure is released.
12 Volt Auxiliary Outlets
(Optional Equipment)
Optional kit # 70.3016. Certain attachments require
a 12 volt auxiliary outlet. Plug the attachment’s 12
volt power cord into the 12 volt 4-pin socket located
in front of the main control panel. Two switches are
used to control the actions of the 12 volt plug. A
momentary on/off/of switch is used for controlling
movement that is only used for a brief time. An on/off
switch is used to activate equipment or select differ-
ent functions.
