GENERAL OPERATION

• Read, understand, and follow all instructions in the
manual and on the unit before starting.

• Only allow responsible adults, who are familiar with
the instructions, to operate the unit.

• Clear the area of objects such as rocks, toys, wire,
etc., which could be picked up and thrown by the
blade(s).

• Be sure the area is clear of other people before mow­ing. Stop unit if anyone enters the area.

• Never carry passengers.

• Do not mow in reverse unless absolutely necessary.
Always look down and behind before and while trav­elling in reverse.

• Be aware of the mower discharge direction and do
not point it at anyone. Do not operate the mower
without either the entire grass catcher or the deflector
in place.

• Slow down before turning.

• Never leave a running unit unattended. Always
disengage the PTO, set parking brake, stop engine,
and remove keys before dismounting.

• Turn off the PTO switch to disengage the blades
when not mowing.

• Stop engine before removing grass catcher or
unclogging chute.

• Mow only in daylight or good artificial light.

• Do not operate the unit while under the influence of
alcohol or drugs.

• Watch for traffic when operating near or crossing
roadways.

• Use extra care when loading or unloading the unit
into a trailer or truck.

SLOPE OPERATION

Slopes are a major factor related to loss-of-control and
tip-over accidents, which can result in severe injury or
death. All slopes require extra caution. If you cannot
back up the slope or if you feel uneasy on it, do not mow it.

Do

• See your authorized dealer for recommendations of
wheel weights or counterweights to improve stability.

• Mow up and down slopes, not across.

• Remove obstacles such as rocks, tree limbs, etc.

• Watch for holes, ruts, or bumps. Uneven terrain could
overturn the unit. Tall grass can hide obstacles.

• Use slow speed. Choose a low gear so that you will
not have to stop or shift while on the slope.

• Use extra care with grass catchers or other attach­ments. These can change the stability of the unit.

• Keep all movement on the slopes slow and gradual.
Do not make sudden changes in speed or direction.

Do Not

•

Do not

start or stop on a slope. If tires lose traction,
disengage the blade(s) and proceed slowly straight
down the slope.

•

Do not

turn on slopes unless necessary, and then,
turn slowly and gradually downhill, if possible.

•

Do not

mow near drop-offs, ditches, or embank­ments. The mower could suddenly turn over if a
wheel is over the edge of a cliff or ditch, or if an edge
caves in.

•

Do not

mow on wet grass. Reduced traction could
cause sliding.

•

Do not

try to stabilize the unit by putting your foot on
the ground.

•

Do not

use grass catcher on steep slopes.

Safety Rules

Read these safety rules and follow them closely. Failure to obey these rules could result in loss of control of
rider, severe personal injury or death to you, or bystanders, or damage to property or equipment. This
mowing deck is capable of amputating hands and feet and throwing objects. The triangle in text
signifies important cautions or warnings which must be followed.

WARNING - SLOPE OPERATION
Never operate on slopes greater than 30 percent
(16.7°) which is a rise of three feet vertically in 10 feet
horizontally. When operating on slopes that are
greater than 15 percent (8.5°) but less than 30 percent
use front counterweights and rear wheel weights (see
your dealer). Select slow ground speed before driving
onto slope. In addition to front and rear weights, use
extra caution when operating on slopes with rear­mounted grass catcher. Mow UP and DOWN the slope,
never across the face, use caution when changing
directions and DO NOT START OR STOP ON SLOPE.

4

CHILDREN

Tragic accidents can occur if the operator is not alert to
the presence of children. Children are often attracted to
the unit and the mowing activity. Never assume that chil­dren will remain where you last saw them.

• Keep children out of the mowing area and under the
watchful care of another responsible adult.

• Be alert and turn unit off if children enter the area.

• Before and when backing, look behind and down for
small children.

• Never carry children. They may fall off and be seri­ously injured or interfere with safe unit operation.

• Never allow children to operate the unit.

SAFETY INTERLOCK SYSTEM

Your tractor is equipped with a seat switch safety system
that will automatically shut the engine off when the oper­ator leaves the seat with the ground speed control lever
in gear or with the PTO engaged. Once the engine has
stopped, the electric PTO switch must be turned off after
operator returns to the seat in order to start the engine.

Check operation of dash safety lights. With operator in
seat and ignition switch turned to ON (engine not run­ning):

A. Neutral Indicator Light (G, figure 2) should go on with

ground speed control lever in neutral gate and should
go out when lever is moved to either the forward or
reverse gate.

B. Front PTO Indicator Light (K, figure 2) should go on

and off with operation of PTO switch.

C. Oil Pressure Indicator Light (F, figure 2) should be on

and should go out immediately after engine starts.

D. Operator Seated Indicator Light (L, figure 2) should

go on when operator is present in the seat and
should go off as operator rises out of the seat.

Check the seat switch (A, figure 3) every fall and spring
with the following four tests:

Test 1 - Engine should NOT crank if:

A. seat is not occupied or
B. ground speed control lever out of neutral or

C. PTO switch engaged.

Test 2 - Engine should crank if:

A. seat is occupied and
B. ground speed control lever is in neutral and

C. PTO switch is disengaged.

Test 3 - Engine should shut off if:

A. operator rises off seat with ground speed control

lever in gear

.

B. operator rised off seat with PTO engaged.

NOTE: If operator returns to seat before engine stops,
the engine will re-start and PTO clutch will re-engage.

Test 4 - PTO will disengage if:

A. operator rises off seat with engine running.

NOTE: If operator returns to seat before engine stops,
the engine will re-start and PTO clutch will re-engage.

Mowing Patterns & Tips

For the first use of the mower, choose a smooth level
area. Cut long straight strips overlapping slightly.

The size and type of area to be mowed determines the
best mowing pattern to use. Obstructions such as trees,
fences and buildings must also be considered. Where
possible, make one or two passes in a counterclockwise
direction around the outside of the area to keep the cut
grass off fences and walks. The remainder of the mow­ing should be done in a clockwise direction so the clip­pings are dispersed on the cut area.

Keep in mind the following lawn care and mowing tips:

• Too much maintenance is as detrimental to your lawn
as neglect.

• Mow when grass is 3-5 inches tall. Don’t cut shorter
than 2 to 2-1/2 inches. Cut only the top one-third of the
grass blade. Cutting below this level can lead to thatch
problems. Your mower has a cutting height adjustment
that can help you maintain a proper length.

• For extremely tall grass, set the cutting height at
maximum for the first pass, and then reset to the
desired height and mow again.

• Mow often. Short clippings of an inch or less decom­pose more quickly than longer blades.

• Keep the blades on your mower sharp for finer clip­pings.

• Let grass grow a bit longer when it is hot to reduce
heat build-up and protect grass from heat damage.

• Use slow-release fertilizer for slow, even growth.

• Don’t cover grass surface with a heavy layer of clip­pings. Consider using a grass collection system and
starting a compost pile.

• Aerate lawn in spring, consider renting an aerator
which removes cores of soil from the lawn. This
increases the speed of clipping decomposition and
deep root growth by opening up the soil and permitting
greater movement of water, fertilizer and air.

• Don’t over-water. Too much water can encourage
disease development.

• Mow when the grass is dry, preferably in the late
afternoon when the temperatures are cooler.

• Where possible, change patterns occasionally to
eliminate matting, graining or a corrugated appear­ance.

• For wet grasses, grasses prone to wheel tracking and
for collecting clippings:

a. Use sharp blades.
b. Raise deck 1/4” higher in front than in rear.

c. Run at maximum engine speed but slow ground

speed.
d. Clean deck of built-up material/caked-on grass.
e. Check for free movement of mower idler pulley.

• For dry conditions where grass blow-out is a problem:
a. Use sharp blades.

b. Raise deck so the front is even with, or 1/8” lower

than, rear.

c. Use 3/4 engine speed.

d. Clean deck of built-up material/caked-on grass.

Storage

TEMPORARY STORAGE
(30 Days Or Less)

Remember, the fuel tank will still contain some gasoline,
so never store the tractor indoors or in any other area
where fuel vapor could travel to any ignition source. Fuel
vapor is also toxic if inhaled, so never store the tractor in
any structure used for human or animal habitation.

Here is a checklist of things to do when storing your trac­tor temporarily or in between uses:

• Keep the tractor in an area away from where children
may come into contact with it. If there’s any chance of
unauthorized use, remove the spark plug (s) and put
in a safe place. Be sure the spark plug opening is
protected from foreign objects with a suitable cover.

• If the tractor can’t be stored on a reasonable level
surface, chock the wheels.

• Clean all grass and dirt from the mower.

NOTE: If storing your tractor between winter snow
removal jobs in a cold area, we suggest that you fill the
fuel tank at the completion of each job to prevent water
condensation in the fuel tank. Wait for engine to cool
before filling tank.

LONG TERM STORAGE
(Longer Than 30 Days)

Before you store your tractor for the off-season, read the
Maintenance and Storage instructions in the Safety
Rules section, then perform the following steps:

1. Drain crankcase oil while engine is hot and refill with
a grade of oil that will be required when tractor is
used again.

2. Prepare the mower deck for storage as follows:

a. Remove mower deck from the tractor.

b. Clean underside of mower deck.

c. Coat all bare metal surfaces with paint or light coat

of oil to prevent rusting.

3. Clean external surfaces and engine.

4. Prepare engine for storage. See engine owner’s
manual.

5. Clean any dirt or grass from cylinder head cooling
fins,engine housing and air cleaner element.

6. Cover air cleaner and exhaust outlet tightly with plas­tic or other waterproof material to keep out moisture,
dirt and insects.

7. Completely grease and oil tractor as outlined in the
Normal Care section.

8. Clean up tractor and apply paint or rust preventative
to any areas where paint is chipped or damaged.

9. Be sure the battery is filled to the proper level with
water and is fully charged. Battery life will be
increased if it is removed, put in a cool, dry place and
fully charged about once a month. If battery is left in
tractor, disconnect the negative cable.

10.Drain fuel system completely or add a gasoline stabi­lizer to the fuel system. If you have chosen to use a
fuel stabilizer and have not drained the fuel system,
follow all safety instructions and storage precautions
in this manual to prevent the possibility of fire from
the ignition of gasoline fumes. Remember, gasoline
fumes can travel to distant sources of ignition and
ignite, causing risk of explosion and fire.

NOTE: Gasoline, if permitted to stand unused for extend­ed periods (30 days or more), may develop gummy
deposits which can adversely affect the engine carbure­tor and cause engine malfunction. To avoid this condi­tion, add a gasoline stabilizer to the fuel tank or drain all
fuel from the system before placing unit in storage.

WARNING

Never store the tractor, with gasoline in engine or fuel tank, in a heated shelter or in enclosed, poorly
ventilated enclosures. Gasoline fumes may reach an open flame, spark or pilot light (such as a furnace,
water heater, clothes dryer, etc.) and cause an explosion.

Handle gasoline carefully. It is highly flammable and careless use could result in serious fire damage to
your person or property.

Drain fuel into an approved container outdoors away from open flame or sparks.

19

11.Transport the tractor to a suitable, dry, indoor loca­tion. If the tractor is to be stored 6 months or longer,
block the tractor up off the wheels to relieve weight
and also to keep the tires off a damp floor. Protect
tires from prolonged exposure to direct sunlight.

STARTING AFTER
LONG TERM STORAGE

Before starting the tractor after it has been stored for a
long period of time, perform the following steps.

1. Remove the blocks from under the tractor.

2. Install the battery if it was removed.

3. Unplug the exhaust outlet and air cleaner.

4. Fill the fuel tank with fresh gasoline. See engine
manual for recommendations.

5. Check crankcase oil level and add proper oil if
necessary.

6. Inflate tires to proper pressure. Check fluid levels.

7. Start the engine and let it run slowly. DO NOT run at
high speed immediately after starting. Be sure to run
engine only outdoors or in well ventilated area.

CHECKING THE BATTERY

The voltmeter can be used to determine condition of bat­tery. When engine is off, the voltmeter shows battery
voltage, which should be 12 volts. When engine is run­ning, the voltmeter shows voltage of charging circuit
which normally is 13 to 14 volts.

A dead battery or one too weak to start the engine may
not mean the battery needs to be replaced. It may, as an
example, mean that the alternator is not charging the

battery properly. If there is any doubt about the cause of
the problem, see your dealer. If you need to replace the
battery, follow the steps under Cleaning the Battery &
Cables in the Normal Care Section.

CHARGING A COMPLETELY
DISCHARGED BATTERY

1. Be aware of all the safety precautions you should
observe during the charging operation. If you are
unfamiliar with the use of a battery charger and
hydrometer, have the battery serviced by your dealer.

2. Add water sufficient to cover the plate (fill to the prop­er level near the end of the charge). If the battery is
extremely cold, allow it to warm before adding water
because the water level will rise as it warms. Also, an
extremely cold battery will not accept a normal
charge until it becomes warm.

3. Always unplug or turn the charger off before attach­ing or removing the clamp connections.

4. Carefully attach the clamps to the battery in proper
polarity (usually red to [+] positive and black to [-]
negative).

5. While charging, periodically measure the temperature
of the electrolyte. If the temperature exceeds 125° F
(51.6° C), or if violent gassing or spewing of elec­trolyte occurs, the charging rate must be reduced or
temporarily halted to prevent battery damage.

6. Charge the battery until fully charged (i.e. until the
specific gravity of the electrolyte is 1.250 or higher
and the electrolyte temperature is at least 60° F). The
best method of making certain a battery is fully
charged, but not over charged, is to measure the
specific gravity of a cell once per hour. The battery is
fully charged when the cells are gassing freely at low
charging rate and less than 0.003 change in specific
gravity occurs over a three hour period.

JUMP STARTING WITH AUXILIARY
(BOOSTER) BATTERY

Jump starting is not recommended. However, if it must
be done, follow these directions. Both booster and dis­charged batteries should be treated carefully when using
jumper cables. Follow the steps below EXACTLY, being
careful not to cause sparks. Refer to figure 24.

1. Both batteries must be of the same voltage (6, 12,
etc.).

2. Position the vehicle with the booster battery adjacent
to the vehicle with the discharged battery so that
booster cables can be connected easily to the batter­ies in both vehicles. Make certain vehicles do not
touch each other.

3. Wear safety glasses and shield eyes and face from
batteries at all times. Be sure vent caps are tight.
Place damp cloth over vent caps on both batteries.

4. Connect positive (+) cable to positive post of dis­charged battery (wired to starter or solenoid).

5. Connect the other end of same cable to same post
marked positive (+) on booster battery.

6. Connect the second cable negative (-) to other post
of booster battery.

7. Make final connection on engine block of stalled vehi­cle away from battery. Do not lean over batteries.

8. Start the engine of the vehicle with the booster bat­tery. Wait a few minutes, then attempt to start the
engine of the vehicle with the discharged battery.

9. If the vehicle does not start after cranking for thirty
seconds, STOP PROCEDURE. More than thirty sec­onds seldom starts the engine unless some mechani­cal adjustment is made.

10.After starting, allow the engine to return to idle speed.
Remove the cable connection at the engine or frame.
Then remove the other end of the same cable from
the booster battery.

11.Remove the other cable by disconnecting at the dis­charged battery first and then disconnect the oppo­site end from the booster battery.

12.Discard the damp cloths that were placed over the
battery vent caps.

Troubleshooting & Repair

WARNING

For your personal safety, use extreme care when
jump starting. Never expose battery to open
flame or electric spark – battery action generates
hydrogen gas which is flammable and explosive.
Do not allow battery acid to contact skin, eyes,
fabrics, or painted surfaces. Batteries contain a
sulfuric acid solution which can cause serious
personal injury or property damage.

CAUTION

To avoid engine damage, do not disconnect bat­tery while engine is running. Be sure terminal
connections are tight before starting.

WARNING

Keep open flames and sparks away from the bat­tery; the gasses coming from it are highly explo­sive. Ventilate the battery well during charging.

23

Troubleshooting & Repair

WARNING

Any procedure other than the preceding could
result in: (1) personal injury caused by elec­trolyte squirting out the battery vents, (2) per­sonal injury or property damage due to battery
explosion, (3) damage to the charging system of
the booster vehicle or of the immobilized vehicle.

Do not attempt to jump start a vehicle having a
frozen battery because the battery may rupture
or explode. If a frozen battery is suspected,
examine all fill vents on the battery. If ice can be
seen or if the electrolyte fluid cannot be seen, do
not attempt to start with jumper cables as long
as the battery remains frozen.

FRONT CLUTCH ADJUSTMENT

Burnishing The Clutch

Before the front clutch is used for the first time, it should
be burnished as follows. Also, if mower cut is rough look­ing, the clutch may require burnishing. To burnish the
clutch, the mower must be installed.

1. Start the engine and set at full throttle.

2. Pull the front PTO switch out to the on position, leave
for 15 seconds, then push in to the off position.

3. Repeat ten times to burnish the clutch.

Clutch Adjustment

1. Remove the tractor hood by disconnecting the head­light coupler and then removing two pins and clip.

2. Use a 0.010” - 0.012” feeler gauge to check front
clutch at three slots (A, figure 28). There should be a
slight resistance as gauge is moved in and out of slot.
If tight or loose, proceed to step 3.

3. Loosen or tighten one of the nuts (B, figure 28) to
achieve slight drag on feeler gauge. Check the other
two slots and adjust accordingly.

NOTE: Adjustment at one location will change adjust­ment at the two other slots. Make sure all three locations

have proper adjustment.

LEVELING THE MOWER

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.

1. With the mower installed, place the tractor on a
smooth, level surface such as a concrete floor. Turn
the front wheels straight forward.

2. Check for bent blades and replace if necessary.

3. Disengage the PTO. Place the mower in mid-cut
position.

4. Arrange the mower blades so that they are pointing
from side-to-side. Measure the distance from the out­side tips of the blades to the ground. If the difference
between the two measurements is less than 1/8” (3
mm), the mower is level side-to-side and you can
skip step 5.

ADJUSTMENTS FOR THE 60” MOWER

Idler Bracket

1. When the belt is installed, the bracket (B, figure 30)
should touch the stop (C, figure 30). The bracket has a
slot (D) so it can be adjusted. If necessary, loosen the
fasteners and move the bracket (B) toward the stop.

2. If the bracket cannot be moved far enough to touch the
stop (C), the idler pulley (A) can be repositioned.
Remove the mounting hardware, noting the position.
Reinstall the pulley in the hole in the mower deck which
is slightly farther away from center of mower.

Roller Bracket

The anti-scalping rollers (A, figure 31) can be adjusted for
different cutting heights by positioning roller brackets on the
mower baffle (B, figure 31).

1. Remove bolts, lockwashers and nuts securing roller
bracket to baffle.

2. For the lowest two cutting heights, roller brackets should
be positioned in the upper set of holes.

3. Use the lower set of holes if mowing is usually done at
higher cutting heights, or if scalping occurs at lower cut­ting heights due to uneven terrain.

BLADE BRAKE ADJUSTMENT

Mower blades and mower drive belt should come to a
complete stop within five seconds after front PTO switch
is turned off.

1. With tractor in neutral, PTO disengaged and operator
in seat, start the tractor engine.

2. Look over the left-hand footrest at the mower drive
belt. Engage the front PTO and wait several sec­onds. Disengage the front PTO and check the
amount of time it takes for the mower drive belt to
stop.

3. If mower drive belt does not stop within five seconds,
perform the steps described under Front Clutch
Adjustment. Repeat steps 1 and 2. If belt still does
not stop within 5 seconds, see your dealer.
