Safety Checks
Safety Interlock System
Tests
WARNING
This unit is equipped with safety interlock switches and other
safety devices. These safety systems are present for your
safety: do not attempt to bypass safety switches, and never
tamper with safety devices. Check their operation regularly.
Disengage the PTO, stop the engine, set the parking
brake, and wait for moving parts to stop before
leaving operator's position for any reason.
If the tractor does not pass the test, do not
operate tractor. Under no circumstance should
you attempt to defeat the purpose of the safety
system.
Operational SAFETY Checks
Your unit is equipped with a seat switch safety system.
Check the seat switch operation every fall and spring with the
following tests.
Functional Tests
Test 1 — Engine should NOT crank if:
• PTO switch is ON, OR
1. Check the tractor for loose bolts, screws, nuts, etc.
2. Start the engine and check all controls for proper
operation: ground speed control pedals, clutch/brake
pedal, parking brake, throttle and choke cables, electric
PTO clutch, headlight switch, steering, attachment lift,
etc.
• Brake pedal is NOT fully depressed (parking brake OFF),
Test 2 — Engine SHOULD crank if:
• PTO switch is OFF, AND
• Brake pedal is fully depressed (parking brake ON)
Test 3 — Engine should SHUT OFF if:
• Operator rises off seat with PTO engaged, OR
3. Stop the engine and check for fluid leaks: oil, gasoline,
or transmission oil.
4. If any control fails to operate properly during testing or
seems to be out of adjustment, check and readjust it
according to the following Adjustments section.
• Operator rises off seat with brake pedal NOT fully
depressed (parking brake OFF).
Test 4 — Blade Brake Check
Mower Blade Stopping Check
Mower blades and mower drive belt should come to a
complete stop within five seconds after electric PTO switch is
turned OFF (or operator rises off seat). If mower drive belt
does not stop within five seconds, re-adjust the PTO clutch
as described in the ADJUSTMENTS section or see your
dealer.
Mower blades and mower drive belt should come to a
complete stop within five seconds after the electric clutch
switch is turned off.
With the tractor in neutral, the electric clutch switch
disengaged, and an operator in the seat, start the tractor
engine. Run the engine at full throttle. Engage the electric
PTO clutch switch and wait several seconds. Disengage
electric clutch switch and check the time it takes for the
mower drive belt to stop. If the mower drive belt does not
stop within five seconds, adjust the PTO clutch according to
the instructions in the Electric Clutch Adjustment section.
Test 5 — Reverse Mow Option (RMO) Check
• Engine should shut off if: PTO is engaged AND RMO is
not activated AND reverse pedal is depressed.
• RMO light should illuminate if: RMO is engaged AND
PTO switch is activated.
NOTE: Once the engine has stopped, the PTO switch must
be turned off after the operator returns to the seat in order to
start the engine.
Seat Switch Connection
Check that the seat switch (A, Figure 4) is connected to
the seat switch wire harness (B).
WARNING
A
B
If the unit does not pass a safety test, do not
operate it. See RMO Switch Adjustment. Under
no circumstance should you attempt to defeat
the purpose of the safety interlock system.

WARNING
For your personal safety, blade mounting
capscrews must each be installed with two spring
washers or a hex washer and spring washer, then
securely tightened. Torque blade mounting
capscrew to 45 - 55 ft. lbs. (61 - 75 Nm).

prevent blade rotation while tightening the blade bolt
(D) to 45-55 ft. lbs. (61-75 Nm).
Reduce & Check Tire
Pressures
The tires are over-inflated for shipping purposes. Inflate
to the pressures shown. Note that these pressures may
differ slightly from the “Max Inflation” stamped on the
side-wall of the tires. The pressures shown provide
proper traction, improve cut quality, and extend tire life.

WARNING
Before checking mower, shut off PTO and engine,
remove the key, and allow all moving parts to
stop.
Leveling The Mower
A
If the cut is uneven, the mower may need leveling.
Unequal or improper tire pressure may also cause an
uneven cut. Make sure tire pressure is correct as
specified in Checking Tire Pressure.
SIDE-TO-SIDE LEVELING
1. With the mower installed, place the tractor on a
smooth, level surface such as a concrete floor. Turn
the front wheels straight forward.
B
2. Check for bent blades and replace if necessary.
3. Place the mower in mid-cut position. Arrange the
outside mower blades so that they are pointing from
side-to-side.
Figure 15. Leveling The Mower Side-to-Side
A. Lift Rod
B. Locknut
4. Measure the distance between the outside tips of
each blade and the ground. If there is more than 1/8”
(3mm) difference between the measurements on
each side, proceed to step 5. If the difference is 1/8”
(3mm) or less, proceed to step 6.
5. Turn the locknut (B, Figure 15) to raise or lower that
side of the mower.
FRONT-TO-BACK LEVELING
6. Arrange the blades so they face front-to-back.
7. Measure the distance from the ground to the front tip
of the center blade, and from the ground to rear tips
of left-hand and right-hand blades.
Note: Front tip of the center blade should be 1/4" (6mm)
higher than rear tips of left-hand and right-hand blades.
If not, proceed with step 8.
B
A
8. To raise front of mower deck, tighten locknuts (A,
Figure 16) and against spacers (B). To lower front of
mower deck, loosen locknuts (A). Locknuts must be
turned evenly on both sides to keep deck level.

Adjustment
Check the PTO clutch adjustment after 250 hours of
operation. Also perform the following procedure if the
clutch is slipping or will not engage.
A
B
1. Remove key from ignition switch and disconnect
spark plug wires to prevent the possibility of
accidental starting while the PTO is being adjusted.
2. See Figure 20. Note the position of the 3 adjustment
windows (A) in the side of the brake plate and the
nylock adjustment nuts (B).
B
3. Insert a .012” feeler gauge through each window,
positioning the gauge between the rotor face and the
armature face as shown in Figure 20.
B
4. Alternately tighten the adjustment nuts (B, Figure 19)
until the rotor face and armature face just contacts the
gauge.
5. Check the windows for an equal amount of tension
when the gauge is inserted and removed, and make
any necessary adjustments by tightening or loosening
the adjustment nuts.

new belt. However, for easier access mower can be
removed. See Mower Removal in the Operation section.
B
C
1. Park the tractor on a smooth, level surface such as a
concrete floor. Disengage the PTO, turn off the
FRONT
engine and lock the parking brake. Remove the key.
2. If mower is not removed, lower the mower lift and
place the mower in the lowest cutting position.

5. Remove the old belt and replace with a new belt.
Make sure V-side of belt runs in arbor pulley grooves
and the flat backside runs against the idler pulley.
6. Some Models: Position the belt stop bracket(s) (C,
Figure 21) in their original positions. There must be
1/8” clearance between the belt stop and the pulleys.
7. Position the idler pulley belt guide (D) in its original
position up against arm (A) so that there is a 1/8" gap
between the pulley and belt guide.
