on the mowerdeck or contactthe engine exhaust

presentinga potentialfire hazard.

2. SLOPE OPERATION

Slopesare a majorfactor relatedtolossof controland tip-
over accidentswhichcan resultin severe injuryor death.

Allslopesrequireextracaution.If you cannotback upthe
slopeor ifyoufeel uneasyon it,do notmowit.
For yoursafety, use the slope gauge included as part of
thismanualtomeasureslopesbeforeoperatingthisuniton
a slopedor hillyarea. If the slope is greaterthan 15° as
shownon the slopegauge,do notoperatethisunitonthat
area orseriousinjurycouldresult.

DO:

• Mowupand downslopes,notacross.

• Removeobstaclessuchas rocks,limbs,etc.

• Watch for holes, ruts or bumps. Uneven terrain

could overturn the machine. Tall grass can hide
obstacles.

• Use slow speed. Always keep machine in gear

when going down slopes to take advantage of

enginebrakingaction.

• Follow the manufacturer's recommendationsfor

wheel weights or counterweights to improve

stability.

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

• Keep all movement on the slopes slow and
gradual.Do notmake suddenchangesin speedor

direction. Rapid engagement or braking could
causethe front ofthe machineto liftand rapidlyflip
overbackwardswhichcouldcause seriousinjury.

• Avoid starting or stopping on a slope. If tires lose
traction, disengage the blade(s) and proceed slowly
straight down the slope.

DO NOT:

• Do not turn on slopes unless necessary; 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 machine by putting your

foot on the ground.

• Do net use grass catcher on steep slopes.

DRIVING ON SLOPES

Refer to the SLOPE GAUGE on page 6 to help

determine slopes where you may not operate safely:

WARNING: Do not mow on inclines with

a slope in excess of 15 degrees (a rise of
approximately 2-1/2 feet every 10 feet).
The tractor could overturn and cause

serious injury.

Operate the tractor up and down slopes, never

across slopes. Do not drive so that the tractor may

tip over sideways.

Before operating the tractor on any slope, walk the
slope to look for possible hazards such as rocks.

mounds, ruts, stumps or other surface irregularities
which could cause the tractor to be upset.
Avoid turns when driving on a slope, if a turn must
be made, tum down the slope. Tuming up a slope
greatly increases the chance of a roll over.
Avoid stopping when driving up a slope. If it is
necessary to stop while driving up a slope, start up
smoothly and carefully to reduce the possibility of

flipping the tractor over backward.

OPERATING THE HEADLIGHTS

To turn the tractor's headlights on:

• Start the engine following the instructions
earlier in this section.

• Turn the key one notch counterclockwise into
the On/Lights position of the ignition switch.

Refer to Figure 4.

To turn the tractor's headlights off:

• Turn the key either into the On position (to
leave the engine running) or the Oft position

(to shut the engine off). Refer to Figure 4.

IMPORTANT: Never move the key into the Start

position while the engine is running. Doing so may

cause damage to your engine's starter.

STOPPING THE ENGINE

• Place the PTO switch in the disengaged

(OFF) position.

• Move the throttle control into the SLOW

position and allow the engine to "idle down"
for ten seconds, then turn the ignition key
counterclockwise to the OFF position.

• Remove the key from the ignition switch to

prevent accidental starting.

IMPORTANT: If you think you've struck a foreign

object, stop the engine immediately. Remove the
wire(s) from the spark plug(s), thoroughly inspect the
unit for any damage, and repair the damage before

restarting and operating the mower.

USING THE LIFT LEVER

To raise the cutting deck, move the lift lever to the

Refer to SAFETY INTERLOCK SWITCHES in this
section.

MOWING

This tractor is equipped with one of MTLTs high

quality cutting decks. The following information will
be helpful when using the cutting deck with your
tractor.

,_ WARNING: To avoid possible injury, do

not allow anyone in the area of the tractor
while mowing. Even if the area to be

mowed has been cleared of foreign
objects, small objects may be picked up
and discharged by the mower.

WARNING: Never direct the discharge

of material toward bystanders or allow
anyone near the machine while in
operation.

• For best results it is recommended that the
first two laps be cut with the discharge thrown

towards the center. After the first two laps,
reverse the direction to throw the discharge to
the outside for the balance of cutting. This will
give a better appearance to the lawn.

• Do not cut the grass too short. Short grass

invites weed growth and yellows quickly in dry

weather.

Mowing should always be done with the
engine at full throttle.

Do not mow at high ground speed, especially
ifa mulch kit or grass collector is installed.

Under heavier conditions it may be necessary
to go back over the cut area a second time to
get a clean cut.

Do NOT attempt to mow heavy brush and
weeds and extremely tall grass. Your tractor is

designed to mow lawns, NOT clear brush.
Keep the blades sharp and replace the blades

when worn. Refer to the MAINTENANCE
section of this manual for proper blade
sharpening instructions.

SECTION 9: ADJUSTMENTS

LEVELING THE DECK

WARNING: Cutting blades are sharp.

Always protect hands by wearing heavy

leather work gloves to grasp blades.

NOTE: Check the tractor's tire pressure before

performing any deck leveling adjustments. Refer to

TIRES in the maintenance section of this manual for

further information regarding tirepressure.

Front to Rear

The front of the cutting deck is supported by a stabi-

lizer bar that can adjusted to level the deck from front
to rear. The front of the deck should be 1/4" to 3/8"

lower than the rear of the deck. Adjust if necessary
as follows:

WARNING: Turn the tractor's engine

off, remove the key from the ignitionswitch
and apply the tractor's parking brake before

making any adjustments to the cutting

deck.

With the tractor parked on a firm, level
surface, place the lift lever in the top notch

(highest position) and rotate the blade nearest
the discharge chute so that it is parallel with

the tractor.

Measure the distance from the front of the
blade tip to the ground and the rear of the

blade tip to the ground. The first measurement

taken should be between 1/4" and 3/8" less
than the second measurement. Determine the

approximate distance necessary for proper
adjustment and proceed, if necessary, to the
next step.

Loosen the two jam nuts on the rear side of
the deck stabilizer bracket. See Figure 8A.

Locate the two lock nuts on the opposite side
of the stabilizer bracket. See Figure 8A.

Tighten the lock nuts to raise the front of the
deck; loosen the lock nuts to lower the front of
the deck.

Retighten the two jam nuts loosened earlier

when proper adjustment is achieved.

Side to Side

If the cutting deck appears to be mowing unevenly, a side to side adjustment can be performed. Adjust if
necessary as follows:

WARNING: Turn the tractor's engine off, remove the key from the ignition switch and apply the

tractor's parking brake before making any adjustments to the cutting deck.

• With the tractor parked on a firm, level surface, place the liftlever in the top notch (highest position) and
rotate the both blades so that they are perpendicular with the tractor.

• Measure the distance from the outside of the left blade tip to the ground and the distance from the
outside of the right blade tip to the ground. Both measurements taken should be equal. If they're not,

proceed to the next step.

• Loosen, but do NOT remove, the hex cap screw on the left deck hanger bracket. See Figure 8B.

• Balance the deck so that both blade tip measurements taken earlier are equal.

after charging. Charge battery in a well
ventilated area and do not allow a spark or
an open flame near the battery.

TIRES

The recommended operating tire pressure is
approximately 10 psi for the rear tires and 14 psi for

the front tires. Refer to the tire sidewall for exact tire

manufacturer's recommended psi. Do not
overinflate. Uneven tire pressure could cause the
cutting deck to mow unevenly.

FUSE

A fuse is installed in your tractor's wiring harness to
protect the tractor's electrical system from damage
caused by excessive amperage. Always use the
same capacity fuse for replacement. If the electrical
system does not function, or your tractor's engine

will not crank, first check to be certain that the fuse

has not blown. It can be found under the hood
mounted behind the top of dash panel on the

corrected. Check for loose connections in the fuse holder. Replace fuse holder if nec-
essary. A dead short may be in the cranking or charging circuit where the insulation
may have rubbed through and exposed the bare wire. Replace the wire or repair with
electrician's tape if the wire strands have not been damaged.
Note: Look for a wire pinched between body panels, burned by the exhaust pipe or
muffler or rubbed against a moving part.
Refer to the OPERATION section ofthis manual for the correct position of the throttle
control and choke for starting.
