CHECK DAILY
Operator Presence Interlock System - Start Operation
For the engine to crank, the parking brake must be ON, the PTO (blades) OFF. Stand on the operator plat-
form and check, one by one, if the engine will crank with the parking brake OFF or the PTO (Blades) ON.
Operator Presence Interlock System - Run Operation
In order for the engine to run, the operator must either be standing on the platform, or walking behind the unit
with the platform up, the parking brake in the OFF position and the LH control handle held down out of the
neutral position.
The engine may also run if the parking brake is in the ON position, the LH control handle is in the NEUTRAL
position rotated up, and the PTO (blades) are OFF.
To check:
1. Start the engine and run at 1/2 throttle.
2. With the LH control handle in the NEUTRAL position rotated up, move the parking brake lever to OFF
and turn the PTO (Blades) ON. Each check should kill the engine after 1/2 second delay. ( A 1/2 second
delay is built into the system to prevent engine cut-out when traversing rough terrain.)
Repair machine before using if the Operator Presence Interlock System does not operate correctly in start or
run. Contact your authorized BOB-CAT dealer.
Hardware
Tighten any nuts and bolts found loose. Replace any broken or missing cotter pins. Repair any other
problems before operating.
Tire pressure
Rear Tires should be kept inated at 12 lbs/in2(.84kg/cm2). Improper tire ination can cause rapid tire wear
and poor traction. Uneven ination can cause uneven cutting. Front tires should be 15p.s.i. (1.05 kg/cm²)
BATTERY-AGM TYPE BATTERY SUPPLIED
Battery acid is caustic and fumes
are explosive and can cause serious injury or death.

ENGINE OIL
Do not perform engine maintenance without the
engine off, spark plug wires disconnected and PTO
disengaged.
AFTER FIRST FIVE (5) HOURS
While the engine is warm:
1. Release the oil drain hose assembly from the
engine clip J. Lay hose assembly over the frame
edge.
2. Remove the rubber cap Dfrom the tip of the
hose assembly and turn the drain valve to allow
oil to drain from the engine. Dispose of used oil
in accordance with local requirements.
3. Clean drain valve and tighten the plastic portion
of the drain valve back into the metal portion of
the valve. Replace rubber cap over the tip of the
valve. Replace hose assembly back into engine
clip.
4. Change oil lter.
5. Fill the crankcase with fresh oil to the full mark.
Do not overll. See engine manual for oil
specications.
DAILY
1. Check oil level with the dipstick.
2. If oil is needed, add fresh oil of proper
viscosity and grade. See engine manual for oil
specications. Do not overll.
3. Replace dipstick before starting engine.
PERIODIC OIL CHANGES
1. See engine manual for oil and lter change inter-
vals after the break-in period.
2. Follow instructions for rst oil change, above.
SPARK PLUGS
Remove each plug and check condition.
– Good operating conditions are indicated if the plug has a light coating of grey or tan deposit.
– A white blistered coating indicates overheating. A black coating indicates an “over rich” fuel mixture. Both
may be caused by a clogged air cleaner or improper carburetor adjustment.
– Do not sandblast, wire brush or otherwise attempt to repair a plug in poor condition. Best results are
obtained with a new plug.
– Set plug gap as specied in engine manual.
FUEL FILTER
An in line fuel lter is located in the fuel supply line. Inspect at every oil change to make sure it is clean and
unobstructed. Replace if dirty.

MAINTENANCE
TRANSAXLES
Inattention to proper safety, operation, or
maintenance procedures could result in personal
injury, or damage to the equipment. Schiller
Grounds Care, Inc. recommends returning the
machine to your authorized Schiller Grounds
Care, Inc. dealer for service or repair.
Perform transaxle maintenance with the engine off,
spark plug wires disconnected and PTO disengaged.
TRANSAXLE FLUID CHANGE
Change the transaxle uid every 200 hours of
operation. It is essential that the exterior of the
transaxle be free of debris, prior to uid maintenance.
1. Remove the three 1/4" lter guard screws and
lter guard A. Remove the oil lter Bfrom the
transaxle and discard. Dispose of used oil in ac-
cordance with local requirements.
2. Wipe the lter base surface off and apply a lm
of new oil to the gasket of the new replacement
lter. Install the new lter by hand, turn 3/4 to
one full turn after the lter gasket contacts the
lter base surface.
3. Re-install the lter guard and torque the three
screws to 65 in. lbs. each.
4. Remove cap C, ll the transaxles through the
expansion tank Dwith approximately 2 quarts of
SAE 20W-50 engine oil PER TRANSAXLE.
Do not overll! If you overll the transaxle while the unit
is "cold", it may overow as it reaches normal operating
temperatures. The oil level should not be above the
manufacturer's suggestions. The oil level should be lled
to the full cold line on the overow tank. This will allow
the space needed for the oil to expand as it warms up.
5. After starting engine, check the uid level and
continue to add oil to overow tank D to ll line
on tank.
6. Purge the transaxles, following the purging pro-
cedures.

QUICKCAT
MOWERS
®
PURGING TRANSAXLES
Due to the effects air has on efciency in hydrostatic
drive applications, it is critical that it be purged from
the system.
These purge procedures should be implemented any
time a hydrostatic system has been opened to fa-
cilitate maintenance or any additional uid has been
added to the system.
Purging may be required if the unit shows any of the
following symptoms:
- Noisy operation.
- Lack of power or drive after short term use.
- High operation temperature, excessive oil
expansion.
1. Check the transaxle uid, ll to proper level, if
required. Should be to the Full Cold Line.
2. Raise the drive wheels off the ground. Support
unit with jack stands or other suitable means.
3. Open bypass valves. To open the bypass valves,
move the parking brake to any OFF position,
then lift and pull bypass control rod Cthrough the
large opening D, until the control rod stop is past
the opening. Drop rod Cinto the small opening
to lock in place. Repeat for the other bypass
control rod. Start engine, slowly move the control
levers in both forward and reverse directions 5
to 6 times. As air is purged from the unit, the oil
level will drop.
4. With the bypass valve closed, and the engine
running, slowly move the control levers in both
forward and reverse directions 5 to 6 times.
5. Stop engine. Check the transaxle uid level, add
uid as required.
6. It may be necessary to repeat steps 3-5 until all
the air is completely purged from the system.
When the transaxle moves forward and reverse
at normal speed, purging is complete.
MAINTENANCE
ENGINE COOLING
Continued operation with a clogged cooling system
will cause severe overheating and can result in en-
gine damage.
- Daily: Clean air intake screen Son air cooled
engines.
- Every 100 hours: Clean cooling ns beneath
blower housing Hwith reference to information in
the engine manufacturer's manual.
HEAVY DUTY CYCLONIC AIR CLEANER
Clean and replace the air cleaner element as
specied in the service chart. Uneven running, lack
of power or black exhaust fumes may indicate a dirty
air cleaner.
To replace air cleaner elements:
1. Unclamp end cover X and remove existing
cleaner elements.
2. Insert new elements Y and Zand replace cover.
Ensure the breathing port Ais pointing down and
towards the front of the tractor.

MAINTENANCE
CLEANING MACHINE
Clean the machine after use. Compressed air is
recommended. Do not use a pressure washer. The
machine will run cooler and last longer if kept free of
clippings and other debris. A clean machine also re-
duces the risk of re due to accumulation of combus-
tible debris and chaff.
Brush or blow clippings and debris off the cutterdeck
and engine deck. Clippings and debris should be
kept from accumulating around the exhaust system
and under the exhaust guards. This can be doen
by using compressed air. DO NOT use a pressure
washer.
WASHING MACHINE
CAUTION: Improperly washing a machine can cause
water to enter bearings and other components. This
can greatly reduce component life.
– Do not use a pressure washer. Do not direct
water at bearings or seals. High pressure water
can blow past seals and enter sealed bearings.
– Allow the machine to cool down before washing.
Water on a warm machine can be sucked into
sealed bearings as they cool.
– Avoid getting electrical connections wet. Water
can cause electrical faults and corrosion of elec-
trical components.

MAINTENANCE
BLADE REMOVAL
Follow these instructions to prevent injury during
blade removal:
1. Loosen with a box wrench or a socket and long
breaker bar. To gain additional leverage, slip a
long pipe or thick-walled tube over breaker bar or
wrench.
2. Insert wood block Aas shown, with grain
perpendicular to blade, to prevent blade from
turning when loosening.
3. Wear thickly padded gloves. Keep hands clear
of blade path. Blades may rotate when bolt
releases.
SHARPENING
Blades may be sharpened by ling or grinding.
- Inspect blades before sharpening.
- Replace bent or cracked blades.
- Replace blades when the lift portion has worn
thin.
-Maintain cut angle at 30o.
-Do not overheat blades when sharpening.
- Always use BOB-CAT blades. Use of another
manufacturer’s blades may be dangerous.
BLADE BALANCE
Blade balance must be maintained at 5/8 oz-in
(19.4 g-cm) or less. Failure to keep blades balanced
causes excess vibration, wear, and shortened life of
most components of the machine.
To balance a blade:
1. Sharpen blade rst.
2. Balance the blade at the center.
3. Attach a 1/8 oz (3.9 g) weight at a distance 5”
(127 mm) from center on the light end. This
should make the light end the heavy end:
- If it does, the blade is balanced.
- If does not, le or grind the heavy end until
the addition of the weight makes the light end
the heavy end.
BLADE INSTALLATION
1. Wear thickly padded gloves to prevent cuts from
the sharp blade.
2. Insert the blade bolt, in order, through the conical
washer (cup side toward the blade, as shown),
the blade, and the blade spacer.
3. Install assembly on the blade spindle.
4. Torque the blade bolt to 70 ft-lbs.

ADJUSTMENTS
DECK LEVELING
1. Park the machine on a smooth, level surface.
Raise the deck to the transport position.
2. Lower the deck onto a set of equal height blocks
Aunder the rear corners of the deck. Place
another set of blocks under the front of the deck
so that the deck top is pitched forward 1/8".
NOTE: The front and rear of the deck are at different
heights.
3. Measure the height of the blade cutting edge
above the ground. Remove pin Band set the
height of cut lever Eto that height
4. Loosen nuts on bolts G. Move bolts in slot to
remove slack in chain. Tighten nuts on bolts G.
A 1/8" forward pitched deck provides the best horsepower.
A level deck provides the best quality of cut.
A 1/8" rearward pitched deck provides the best striping.
Certain grass types and conditions may vary.
HEIGHT OF CUT
The height of cut is set by moving height of cut pin B
to the hole designated for the height of cut desired.
To change the height of cut:
1. Lift the deck to the highest position using the lift
handle E.
2. Move pin Bto the selected hole.
3. Lower the deck until the lift handle Eis stopped
by the pin.
NOTES:
– Height of cut may vary due to the amount of
tread on the tires, tire diameter or ination pres-
sure.
– For best results, adjust the deck rollers for the
height of cut to be used (see below).

15
QUICKCAT
MOWERS
®ADJUSTMENTS
DECK ROLLERS
The rear outside deck rollers are adjustable up and
down to provide improved deck otation and scalp-
ing protection at various heights of cut. They are not
intended to ride continuously on the ground. Adjust
no closer than 3/8” (10mm) to the ground.
Height of cut ranges for roller adjustment
FRONT DECK LIP
Adjustable front deck lips have been provided on
48in. 52 in. and 61" cutterdecks for various grass
types and cutting conditions.
To revise per conditions:
1. Loosen the front bolts S.
2. Adjust height of H.
3. Retighten Sonce you have desired height.
Suggested heights for grass types:
(Factory setting is all the way down.)
-Southern season grasses generally will work with
the lip down. When cutting Bahia grass or other
grasses where seed pods grow higher then the
actual grass blade, you will want to adjust the lip all
the way up.
-Northern season grasses generally require the lip
all of the way down.

2. Set the cutterdeck in a middle height-of-cut posi-
tion.
3. Loosen bolt on belt guide so belt guide can be
moved to remove the belt.
4. Insert 3/8" ratchet extension in hole A on the
idler arm to back tensioning idler off to remove
belt from idler. Remove belt from cutterdeck
pulleys.
5. Remove belt from clutch pulley.
6. Install the new belt by performing these steps in
reverse order.
7. Cutterdeck spring will require tension adjustment
after belt installation. Adjust eyebolt so the dis-
tance between the inside of the eyebolt and the
inside of the hook is 6-3/4 ± 1/8".
TRANSAXLE DRIVE BELT
