OPERATION Figure 2. To stop or slow down, gradually pull the control
lever toward the neutral (N) position or depress the
neutralizing pedal.
PRE-STARTING INSPECTION
Prior to starting the engine for each day's operation, the
following checks and services should be performed:
a. Check oil in engine crankcase. Add oil as required to
maintain proper level.
b. Check fuel supply. Use regular gasoline only.
c. Check air filter for excessive dirt. Clean as required.
d. Make visual check with regards to safety precautions,
obstructions, lubrication, and maintenance.
STARTING THE ENGINE
Use the following procedure to start the engine:
1. Place the hydrostatic control lever in the "Park-Start"
position, shown in Figure 2.
NOTE: This is a safety feature. The engine wiii not start
unless the control lever is pulled all the way to the rear of
the "Park-Start" slot
2. Be sure the Implement Power Control Switch(T)Figure
1,.is pushed in (OFF).
NOTE: This is a safety feature. The engine will not start un­
less the switch is off (pushed in).
3. Raise throttle lever ©Figure 1, to approximately 1/3
fast position.
4. Pull choke control ©Figure 1, all the way out if engine
is cold. If engine is warm, little or no choke may b''
required.
5. Turn ignition key ©Figure 1, clockwise all the way.
Release key as soon as the engine starts and push choke
button in. In cold weather it may be necessary to push choke
in gradually until engine warms up. If engine fails to start
on the first attempt, turn key to off, wait a few minutes and
try again. Do not operate the starting motor continuously
for more than 30 seconds at a time.
Always allow engine to warm up before applying load.
In below freezing weather, allow engine to run at a fast idle
for a period of at least 5 minutes before using the tractor.
Serious internal damage to the engine and hydrostatic trans­
mission could result if this procedure is not followed.
NOTE: The lines next to the forward slot do not indicate
a given speed and serve as guide lines only.
To move the tractor backward and increase reverse travel
speed, gradually pull the hydrostatic control lever back In
the reverse (R) slot from the neutral (N) position, shown in
Figure 2. To stop or slow down, gradually push the control
lever toward the neutral (N) position or depress neutralizing
pedal slowly with foot.
To stop the tractor, return the control lever to neutral
either by hand or with the neutralizing pedal and then step
on the brake to stop tractor from rolling.

CONTROL LEVER
When the hand control lever is placed in the "Park-
Start" position as shown in Figure 2, a pin engages in the
teeth on the reduction gear inside the rear axle housing. This
mechanically locks the rear wheels and prevents them from
turning. When the control lever is moved into the neutral
(N) position. Figure 2, the pin is disengaged; however, the
hydrostatic transmission will not allow the rear wheels to
turn provided there is sufficient oil in the transmission and
the free-wheeling valves are not depressed.
To move the tractor forward and to increase forward
travel speed, gradually push the hand control lever for­
ward in the slot from the neutral (N) position, shown in
Because of the dynamic braking characteristics of the
hydrostatic transmission the control lever is extremely
sensitive to the slightest movement when in the forward or
reverse slots. Always move lever slowly when in these slots.
When the tractor is stopped on a hill or grade and the
control in neutral, a slight amount of tractor movement is
considered normal, if wheel brakes are not applied after
neutralizing transmission speed control.
The forward travel speed of the tractor is infinitely
variable from 0 to 6.8 mph. The reverse travel speed is
infinitely variable from 0 to 3.2 mph with the engine running
full throttle.
