any choking. If the engine does not start after about 10 sec¬
onds of cranking it may be receiving too rich a fuel mixture.
Push the choke in and try again. The engine may not need to
be choked when starting it in warm weather or if it has been
operated recently.
7. Release the clutch-brake pedal as soon as the engine is
running smoothly.
STOPPING THE ENGINE
1. Move the engine speed control lever to the SLOW posi¬
tion.
2. If the tractor has been operating under full load, allow
the engine to idle for about a minute to reduce the engine
temperature. Stopping a hot engine too suddenly can dam¬
age engine parts.
3. Turn the ignition key counterclockwise to the vertical
position to stop the engine.
4 Set the parking brake.
5. Remove the ignition key to prevent unauthorized use of
the tractor.
CONTROLLING TRACTOR GROUND SPEED
Tractor ground speed can be controlled by the position of
the hydrostatic transmission control lever and/or the engine
speed control lever.
ENGINE SPEED
Most power take off driven attachments operate best at a
particular speed. Since the speed of the power take off drive
is direedy related to the engine speed it is desirable to ad'
just the engine speed to control attachment speed and use
the hydrostatic lever to control ground speed. For pulling
light loads or transporting the tractor and attachments from
one area to another, adjusting the engine speed is one meth¬
od of controlling tractor ground speed.
HYDROSTATIC TRANSMISSION CONTROL
The hydrostatic equipped tractor is designed so that for¬
ward and reverse movement can be completely controlled
without the use of the clutch. Simply squeeze the control
handle and move it forward to start the tractor moving
ahead. To slow the tractor move the control to the rear. As
the control is moved further away from neutral the tractor
ground speed will increase. The clutch and brake pedal may
be depressed to stop the tractor at any time. It is very handy
to use the clutch to slow down for turns or when mowing
in confined areas when both hands are needed for steering.
STARTING TRACTOR TRAVEL
Assure yourself that the area in which you are going to drive
the tractor is free of obstructions. Release the parking brake
and look around to insure there are no obstructions in your
path- To start the tractor in motion T squeeze the trigger of
the hydrostatic control lever with your right hand, and move
it forward or back from the neutral position slowly until you
have reached the desired speed. Always move the hydrostatic
control lever slowly to prevent abrupt and dangerous speed
changes. CAUTION: DO NOT STOP OR START SUDDEN¬
LY WHEN GOING UP OR DOWN HILL. MOW UP AND
DOWN THE FACE OF STEEP SLOPES; NEVER ACROSS
THE FACE. REDUCE SPEEDONSLOPES AND IN SHARP
TURNS TO PREVENT TIPPING OR LOSS OF CONTROL.
EXERCISE EXTREME CAUTION WHEN CHANGING DI¬
RECTION ON SLOPES.
STOPPING TRACTOR TRAVEL
To stop the tractor squeeze the trigger toward the hydrosta¬
tic transmission control lever and move the lever slowly to¬
ward the NEUTRAL position. In emergencies or if both
hands are required on the steering wheel, you may depress
the clutch and brake pedal to stop the tractor. Before leaving
the tractor seat, shut off the engine, set the parking brake,
and remove the ignition key.
HOT WEATHER OPERATION
When operating the tractor at temperatures above 75*F pay
particular attention to the following items to prevent dam¬
age.
1. Keep the engine cooling fins dean and free of obstruction
which would decrease air flow to and from the engine. See
page 15 for cleaning instructions.
2. Keep the transmission oil (fluid) cooler clean and free of
dirt and chaff which would restrict air flow. Also keep the
cooler free of oil. An oil film on the outside of the cooler
greatly reduces its cooling ability. See page 15 for instruc¬
tions on cleaning the oil cooler.
3. Insure that you are using the proper grade and weight of
oil in the engine for the temperature where the tractor is be*
mg used. Check the oil level each time you fill the fuel tank.
DO NOT OVERFILL THE CRANKCASE - ENGINE
OVERHEATING MAY RESULT.
4. Check the battery water level more frequently than every
25 hours which is recommended under normal conditions.
High temperatures cause faster evaporation of water from
the battery.
5. Remove the carburetor heat deflector used with the snow
thrower or dozer blade.
COLD WEATHER OPERATION
When the tractor is being used in temperatures below 30° F,
check the following items closely:
1. Use the correct grade and weight of oil for the tempera¬
ture conditions. Change the oil only when the engine is warm.
If an unexpected temperature drop occurs when the engine
is filled with summer oil, before starting the engine, move
the tractor to a warm location until the oil will flow freely.
2. Use fresh ftiel. Fill the fuel tank after each days use to
protect against moisture condensation.
3. Disengage the clutch when starting the engine.
4. Install the heat deflector furnished with the snow thrower
or dozer blade if these attachments are to be used.
DUSTY OPERATING CONDITIONS
When the tractor is operated in dusty or dirty conditions
check the following items closely:
1. Keep the engine and transmission oil cooler fins dean and
free of materials which will decrease air flow.
2- Service the air cleaner more frequently- Clean or replace
it as often as necessary to allow air to flow to the carburetor
freely.
3- Change the engine oil more frequently. The oil should be
