proceeding.
CONTROLS AND FEATURES
See Figure 5 for controls and features locations.
OPERATION
The blades MUST stop whenever the operator removes both
hands from controls while the PTO is engaged. To test:
1. Start engine and engage PTO.
2. Release operator presence control lever(s). Blades
must stop.
NOTE: All motion must stop whenever operator releases
control levers.
SAFETY INTERLOCK SYSTEM
DANGER: SAFETY INTERLOCK SYSTEM
FAILURE and improper operation of unit can
result in death or serious injury. ALWAYS know
the safety interlock system is operating
properly. See Check Safety Interlock System on
page 10 for testing instructions.
Check Safety Interlock System
Test the safety interlock system at each operation. If the
system does not function properly, do not operate the unit
until repairs are made.
The engine will only start with the PTO disengaged. Pistol
grip models must have the shift lever in neutral for engine to
start.
988100, 102, 103, 110, 112
Engine must not start unless PTO is disengaged and the
shift lever is in neutral. To test:
1. With engine off, engage PTO.
2. Turn e lectr ic st art mode l ign ition switch to Start. Engine
must not crank.
Turn recoil start model ignition switch to On. Pull recoil
start handle. Engine must not start.
3. Disengage PTO.
The engine MUST stop whenever the operator removes
both hands from controls while the PTO or transmission is
engaged. To test:
1. Start engine and engage PTO.
2. Release operator presence control lever(s). Engine
must stop.
3. Disengage PTO.
4. Restart engine.
5. Place shift lever in Forward.
6. Release operator presence control lever. Engine must
stop.
Operator Presence Control (988100, 102, 103, 110,
112)
The operator presence control lever must be depressed to
operate the PTO or traction drive. When the shift lever or
PTO is engaged, releasing the operator presence contr ol
lever stops the engine.
Operator Presence Control
(988114, 1 15, 118 , 119, 313)
The operator presence control levers must be depressed to
operate the PTO. When the PTO is engaged, releasing the
operator presence control levers stops the mower blades.
CAUTION: AVOID INJURY. Operate only when
operator presence control is functioning
correctly. See Check Safety Interlock System on
page 10 for testing instructions.
Steering Levers (988100, 102, 103, 110, 112)
WARNING: A VOID INJURY. When the engine is
running and the shift lever is engaged, releasing
only one steering latch causes the unit to circle
around one drive wheel.
ALWAYS hold both steering levers in the neutral
position when releasing the steering lever
latches.
ALWAYS release l evers slowly.
The steering levers are used to steer, operate in forward and
reverse, and stop the unit. When held in neutral, the brakes
are engaged.
Steering Lever Latches (988100, 102, 103, 110, 112)
The steering lever latches hold the steering levers in neutral
and apply the brakes.
988114, 1 15, 11 8, 119, 313
Blades must not rotate unless the operator presence control
levers and PTO are engaged. To Test:
1. With engine on, release operator presence controls
and engage PTO.
2. Blades must not rotate.
3. Disengage PTO.
GB-10
Control Levers (988114, 115, 11 8, 119, 313)
WARNING: AVOID INJURY. When the engine is
running and the shift lever is engaged, moving
only one lever causes the unit to circle around
one drive wheel.
ALWAYS move levers slowly.
The control levers are used to steer, operate in forward and
reverse, and stop the unit. Push forward to move forward.
Shift into reverse and pull up on the lower control levers to
move in reverse. When held in neutral, the brakes are
engaged.
Ignition Switch (988100, 102, 103, 110, 112, 114,
115, 118, 119, 313)

prematurely. Align the shift lever and detent as carefully as
possible. The .030 in. (.8mm) clearance helps prevent
premature wear of the detent plate and shift lever.
The transmission shift lever is attached to the transmission
shift arm with two 5/16-18 bolts (Figure 12).
Loosen hardware
and adjust detent
plate, if necessary.

2. Remove mower drive belt from mower clutch sheave.
Refer to Belt Replacement for your deck.
3. Remove transmission belt idler spring
(Figure 14).
WARNING: AVOID INJURY. An extension
spring, when extended, stores energy and
can be dangerous. Always use tools
specifically designed for installing or
removing an extension spring. Always
compress or extend springs slowly.

9. Reposition clutch bracket, replace engine bolt, and
torque both engine bolts to 17 lbf-ft (23 N•m).
2. Measure the air gap between the armature and the
rotor.
Minimum: A .005" feeler gauge should slide between
armature and rotor with slight contact.
Maximum: A .023" feeler gauge should slide between
armature and rotor with slight contact.
3. Repeat for each inspection slot.
To adjust:
1. If necessary, loosen gap adjustment nuts until a .005"
feeler gauge fits between armature and rotor.
2. Slide a .012" feeler gauge between armature and rotor.
3. Tighten gap adjustment nut until there is slight contact
on feeler gauge.
4. Repeat steps 1 – 3 at each inspection slot.
NOTE: Adjust air gap as evenly as possible.
5. Start unit, engage and disengage PTO.
6. Shut off unit.
7. Recheck air gap and adjust if needed.
