2. The engine should be run with the throttle
control in the “FAST” position to obtain the
maximum efficiency. The sound you may hear
when you accelerate is the normal operating
sound of the hydrostatic transmission. The
faster you push the control lever forward or
backward, the louder the sound.
3. Release the brake and move the control lever
into either the forward (F) or reverse (R) posi­
tion.
4. The brake pedal is used for emergency stop­
ping only. Normal stopping is done by using
the control lever. When the brake pedal is
depressed the control lever will return close
to the neutral position so the tractor brake will
stop the tractor, however, the tractor may
creep either forward or backward when the
brake pedal is released.
Maintenance and adjustments for the engine are
covered in the Engine Operating and Maintenance
Instructions manual.

FULL mark on the dipstick. Check the oil level
every 8 hours of operation.
Use 20 weight oil with a zinc additive package
of .07% minimum. The following list of oils
