SAFETY INFORMATION
Read This Manual Carefully and Thoroughly Before Operating Your Mower!
1. Carefully and thoroughly read the owner's manual. Allow adequate time to fully understand the
controls and operation of the equipment. Never allow anyone to operate the mower that has not read
and fully understood the owner's manual.
2. Never allow anyone to operate the mower who is not old enough, large enough, and strong enough to
safely handle the machine.
3. Do not carry passengers. Avoid mowing while people, especially children, and pets, are nearby since
rotating blades can throw rocks and other items with enough force to cause serious injury.
BEFORE USING EQUIPMENT
OPERATOR
Wear protective clothing while mowing. Long trousers and safety glasses will help reduce the risk of
injury from thrown objects. It is recommended that steel toe shoes with aggressive soles or some other
type of substantial footwear be worn to help protect your feet and maintain traction on slopes or uneven
ground.
MOWING AREA
Thoroughly inspect the area where the equipment is to be used. Look for items such as stones, sticks,
bones, wire, and other objects. When struck by the mower, these and other objects may become
projectiles that could lead to serious injury and/or death.
MOWER
For your safety and the long life of your mower, always inspect the mower before each use. Before
inspection, make sure the mower is on a flat and level surface, the blades are disengaged, the ignition
switch off with the key removed, and the spark plug wire is off of the spark plug(s) and hidden so that
accidental contact cannot be made.
GENERAL CONDITION
Walk around the mower looking for any fluid spills or leaks on or underneath the mower.
Remove any and all excessive debris, dirt, and/or fluids.
Look for signs of damage or excessive wear. Check the tightness of all nuts, bolts, pins, and
screws. Tighten any that may be loose and replace any that may have been lost during use.
Be sure the safety interlock controls are operating properly so that the engine cannot be started
unless the ground speed control lever is in neutral and the blades disengaged.
Check the mower blades for any damage or abnormal wear and replace in sets so that they are
balanced.
Check the mower cutting height to assure a high quality and even cut.
Check the tire pressure on all four (4) tires.
Check all belts for proper wear and correct tension.
Check engine oil and air filter as recommended in the engine manufacturer's operators manual.

OPERATION OF EQUIPMENT
1. DANGER: Gasoline is highly flammable and explosive. Do not add fuel while engine is running or is
hot. Keep open flames,sparks,and heat away from the fuel and store fuel in containers specifically
designed for that purpose.Add fuel outdoors only and if the fuel is spilled, Do not start the engine.
Manually push the mower away from the spill and immediately wipe up.
2. DANGER: Gases emitted by a charging battery are explosive.Keep heat,sparks and open flames
away from a charging battery.
3. Do not operate the engine in a confined space where dangerous carbon monoxide fumes can
collect. Carbon monoxide is odorless, tasteless, and can be fatal.
4. Mow only in daylight.
5. Make sure the mower is in neutral and the blades are disengaged before attempting to start the
engine.
6. Do not stop or start suddenly when going uphill. Never use riding attachments on slopes since
there is an increased risk that they might roll over.
7. Avoid steep slopes and use extreme caution when changing directions or speed when operating on
a slope.
8. Be extremely careful when operating on a slope or when the grass is damp or wet. Reduced traction
could cause sliding. Never mow by pulling the mower back towards you as you might slip.
9. Watch for traffic when crossing surfaces other than grass (i.e. transporting), loading a trailer or
vehicle, or when the mower is not in use.
10. Never operate the mower with defective guards, shields, or without the safety devices securely
mounted in place.
11. Never direct discharge of material toward bystanders or allow anyone near the mower while in
operation.
12. Do not change the engine governor settings or over-speed the engine.
13. Always stop the engine whenever you leave the mower, even for a moment.
14. To help reduce the risk of a fire hazard, keep the engine and the area around the engine free of grass,
leaves, or any other type of foreign material.
15. Beware of cutting edges. Always wear gloves for safety when performing blade maintenance
activities. Beware on multiple blade units since the rotation of one blade may cause the rotation of
the other blades.
16. Keep body and hands away from pin holes or nozzles that eject hydraulic fluid since fluid escaping
under pressure may have sufficient force to penetrate skin and cause serious injury. If foreign fluid is
injected into the skin, it must be surgically removed within a few hours by a doctor familiar with this
form of injury. Always use paper or cardboard and not hands to search for leaks.

TRANSAXLES
WARNING
Inattention to proper safety, operation, or maintena-
nce procedures could result in personal injury, or
damage to the equipment.
Perform transaxle maintenance with the engine
off, spark plug wires disconnected and PTO
disengaged .
TRANSAXLE FLUID CHANGE
Change the transaxle fluid every 200 hours of oper-
ation. It is essential that the exterior of the transaxle
be free of debris, prior to fluid maintenance.
1. Remove the three 1/4" filter guard screws and
filter guard A. Remove the oil filter Bfrom the
transaxle and discard. Dispose of used oiI in
accordance with local requirements.
2. Wipe the filter base surface off and apply a
film of new oil to the gasket of the new
replacement filter. Install the new filter by
hand, turn 3/4 to one full turn after the filter
gasket contacts the filter base surface.
3. Re-install the filter guard and torque the three
screws to 65 in. lbs. each.
4. Remove cap C, fill the transaxles through the
expansion tank Dwith approximately 2 quarts
of SAE 20W-50 engine oil PER TRANSAXLE .
CAUTION
Do not overfill! If you overfill the transaxle while
the unit is "cold", it may overflow as it reaches
normal operating temperatures. The oil level should
not be above the manufacturer's suggestions. The
oil level should be filled to the full cold line on the
overflow tank. This will allow the space needed for
the oil to expand as it warms up.
5. After starting engine, check the fluid level and
continue to add oil to overflow tank Dto fill line
on tank.
6. Purge the transaxles, following the purging
procedures.

PURGING TRANSAXLES
Due to the effects air has on efficiency in hydrosta-
tic 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
facilitate maintenance or any additional fluid 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 fluid, fill to proper level, if
required. Should be to the FuII 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 C
through 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 fluid level,
add fluid 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.
HEAVY DUTY CYCLONIC AIR CLEANER
Clean and replace the air cleaner element as
specified 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. Remove end cover Xand remove existing
cleaner elements.
2. Insert new elements Yand replace cover.
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 fins beneath
blower housing Hwith reference to inform-
ation in the engine manufacturer's manual.

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
reduces the risk of fire due to accumulation of
combustible debris and chaff.
Brush or blow clippings and debris off the cutter-
deck and engine deck. Clippings and debris should
be kept from accumulating around the exhaust
system and under the exhaust guards. This can be
done 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
electrical components.

long pipe or thick-walled tube over breaker
bar or wrench.
2. Clamping the spindle with a wrench as
shown, 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 filing or grinding.
Inspect blades before sharpening.
Replace bent or cracked blades.
Replace blades when the lift portion has worn
thin.
Maintain cut angle at 30°.
Do not overheat blades when sharpening.
Always use Bradley blades. Use of another
manufacturer’s blades may be dangerous.

BLADE BALANCE
Blade balance must be maintained at 5/8 oz-in
(1 9.4 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 first.
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 Iight end.
This should make the light end the heavy
end :
If it does, the blade is balanced .
If does not, file 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
spring washer (cup side toward the blade,
as shown), the plain washer, the blade, and
the blade spacer.
3. Install assembly on the blade spindle.
4. Torque the blade bolt to 110 ft-lbs.

BELTS
All belts are tensioned by spring loaded idlers. No adjustment is required.
DECK LEVELING
The deck roller needs to be installed at the top hole
1. Park the machine on a smooth, level surface, pull the
cut lever E to the highest slot.
2. Place two 1-3/16" block under the rear deck and a
1-1/16" blocks under the front deck .
3. Remove the pin B to the lowest cutting height, and
then lower the deck onto the blocks.
So that the deck top is pitches forward 1/8".
4. Loosen nuts on bolts G. Move bolts in slot to remove
slack in chain.
5. Tighten nuts on bolts G.
NOTE: The front and rear of the deck are at different
heights.
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.
CUTTING HEIGHT
The cutting height 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 inflation pressure.
For best results, adjust the deck rollers for the height
of cut to be used (see below).
