Avoid operatinq tractor on hi!ls:des and slopes. To mini-
mize the possibility of accidenis r',trile ooerating on hills
and/or rough terrain, obey a comb;nailon of rules, prac-
tices and good common sense.
These include:
1. Reading, understanding, and obeying ail rvritten safety
messages appearing on decais on the machine and in
operator's manuals.
2. Learning from your operator's rnanual and carefully
f rom EXPERIENCE holv io operaie your tractor cor-
rectly. Know your tractor's limiiations.
3. Knowing the terrain on which you are operating your
tractor. There are terrain conditions on which yor.rr
tractor cannot be operated!
4. Learning to expect changes in operating conditions.
Adding or removing attachments or weight to your
tractor will make your tractor perform differently.
Rain, snow, loose gravel, wet grass, etc., change the
tractive conditions of the terra:n recuiring changes in
your operating technique oi- no: io ope!'ate on that
ter ra i n.
The following paragraphs rvill cover Jrese practices one at
a time. Read and study 'rhem. The examples provided are
not all inclusive but vrill g:ve yo,; a firm understanding of
the requirements for avo;d ng accidents while operating
your tractor.
Case lawn and garden tractors are designed and built to
comply with the Voluntary Standard ANSI 871.1 1980
(American National Standards lnstitute).
THE OPERATOR IS THE SOLE JUDGE AS TO THE
DEGBEE OF SLOPE ON WHICH THIS TRACTOR CAN
BE SAFELY OPERATED. IF IN DOUBT THAT THIS
TRACTOR CAN BE SAFELY OPERATED ON A PAR-
TICULAR SLOPE, DO NOT OPERATE ON THAT
SLOPE! COMMON SENSE MUST PREVAIL.
Read, Understand, @y'
Safety messages are found on the tractor and in the op-
erator's manuals. Theseq! be understood by the 114-
tor operator to be of value. Be sure that these messages
are studied before starting and/or operating the tractor by
an operator not familiar with this particular tractor.
HI LLSIDE (SLOPE) OPERATION
Learn to Opgg3.1S
Learn your tractors controls from decals on the tractor
and from instructions in the operator's manual. Practice
how to properly manipulate these controls. Practice must
be done in a flat area, clear of obstacles and bystanders.
Learn your tractors operating characteristics and limita-
tions. These include:
a, amount of engine power available
b. engine governor response
c. tractive ability
d, steering characteristics
e. braking characteristics
f. movement of travel lever
g. forward and reverse ground speeds
h. speed of attachment lift
i. and others
Attempting any operation which approaches or exceeds
the tractor's limitation is risking an accident.
Know the Terrain:
Know the terrain on which you are working. Find hidden
obstacles by walking through and inspecting the area
prior to operating your tractor on it. Mark obstacles, such
as, rocks, ruts or holes with a 6 ft. long pole and red flag
and ggy well clear of these obstacles when ope3!!S.
Operate your tractor at a ground speed slow enough to in-
sure complete control at all times.
Place the transmission in low range and regulate the travel
control lever slowly and smoothly to maintain this safe
speed.
Always drive in a forward direction when proceeding
downhill. Never drive up a hill. lf necessary, back up a
hill to the desired position. Always back up loading ramps
and tilt bed trailers. lf necessary to turn while on a hill,
always turn downward.
Your judgement, based on operating experience is the
final word in deciding if you should negotiate any given
hill or slope. lf you are in doubt about safety - g-I1\!
OFF THE SLOPE.
Under no circumstances should an inexperienced operator
attempt to use your tractor on slopes or hillsides.

move freely to cut level and even.
2. fhe gauge wheels must not contact the ground while
the lawnmower is in the transport position.

LAWNMOWER FRONTTO REAR LEVEL
Smooth cutting and minimum horsepower consumption
are a result of a level rotary mower.
BEFORE STARTING THE PROCEDURE:
1. Put the tractor and rotary mower on a level surface,
like a concrete floor.
2. Put the height selector lever in the "M" position.
3. Lower the lawnmower to the cutting position.
TO RAISE THE FRONT OF THE LAWNMOWER:
1. Loosen the rear nuts that hold the leveler links.
2. Turn the two front nuts rearward an equal number of
turns.
TO LOWER THE FRONT OF THE LAWNMOWER:
1. Loosen the front nuts that hold the leveler links.
2. Turn the two rear nuts forward an equal number of
tu rns.
TO CHECK FOR LEVEL:
1. Rotate the blades until they are parallel to the trac-
tor frame from front to rear.
2. Make sure the nuts on the leveler links are tight.

3. Measure the distance from the blade ends to the level
surface. Make sure you measure as near the blade end
as possible.
The lawn mower is level when both front and rear blade YJ
measurements are the same. The front end may be 1 '8"
(3 mm) lower than the rear end. Never permit the rear
end to be lower than the front end. This will cause more
than normal power consumption.
LAWN I\4OWER SIDE TO SIDE LEVEL
Make sure the problem is not the air pressure in the tires.
The air pressure in both tires must be correct and equal.
Lawn mower side to side level is adjusted at the factory.
lf additional adjustment is necessary:
1. make sure the lawn mower is level "front to rear"
2. move the tractor and lawn mower to a level surface
3. move the height selector lever to the "M" position
4. lower the lawn mower to the cutting position
5. loosen the two bolts that fasten the guage wheel car-
rier to the lawn mower

MAINTENANCE
. /
BLADE BOLTS
Before you operate the lalvn mower for the first time.
check the bolts holding the blades. The bolts must be
tight. After the first eight hours of operation, check the
bolts again. Each time the blades are removed, install new
lock washers under the bolt heads. Tighten the bolts and
check again after 8 hours of operation.
BENT BLADES
CNreck for a bent blade before you install the lawn mower
on the tractor. Check the blades for damage after you hit
foreign material.
The ends of the blades must be aligned horizontally. A
118" (3 mm) difference is acceptable.
Align two blades as shown in Figure 7. Check all six ends
in a similar way. Replace all bent blades.
Bent blades will leave strips of grass not cut.
MOWER GAUGE WHEELS
Two acceptable methods of lubrication:
a. Lubricate the gauge wheels every eight hours of use.
Remove the gauge wheels to apply grease to the
bushi ngs.
b. Apply oil every four hours to the bolts and bushings of
the gauge wheels. You do not need to remove the
gauge wheels to apply oil. Tilt the lawn mower deck
Let the oil flow into the bushings.

1. Remove the deck belt guard.
2. Release the idler pulley tension. Put a 9/16" wrench
on the nut which holds the idler pulley. Rotate the
wrench towards the front of the deck.
3. Remove the old belt.
Put the new belt around the three spindle pulleys and
idler pulley.
Manually rotate the belt. Check for free movement of
the belt. Make sure the idler pulley has tension.

SHARP BLADES
Stop the engine. Wait for all motion to stop. Be careful
while you check the lawn mower blades. After each job
check for damage or blade wear.
A blade that is worn can give a rough cut and brown areas
of grass can result.
See Figure 9 for the correct angle of the cutting edge.
The cutting edge must be at least 3'1 12" (90 mm) long'

NOTE: The K46 and L46 lawn mower blades have dif-

shorter than the outside blades'
Make sure the shorter blade is installed on the
center sPindle.
Manually rotate the blades after installation'
Check for correct clearance through one com-
plete turn.
After grinding a blade. check for balance. Use a balance
tool as shown. A balanced blade will stay in a horizontal
posi ti on.
CLEANING THE LAWN MOWER CHASSIS
Large amounts of grass in the mower deck will:
1. cause more than normal horsepower consumption
2. cause an obstruction
3. cause a bad cutting job
4. cause corrosion
5. damage bearings or seals
Stop the engine. Wait for all motion to stop. Use caution
rntren you check the lawn mower deck. Periodically check
and clean the deck. Remove the grass wound between the
blade mounting plates and spindle housings.
TRACTOR AND ENGINE MAINTENANCE
Complete instructions for tractor and engine mainten-
ance are in your tractor operator's manual.
CHECK AND CLEAN DAILY:
1. Fins of the heat exchanger.
2. Air intake screen of the engine.
3. Air cleaner element.
During dusty or dry conditions use a precleaner. The pre'
cleaner fits over the air cleaner element and gives the ele'
ment a longer life.
The precleaner can be washed with detergent and water.
