HYDROSTATIC TRANSMISSION
The hydrostatic transmission gives the operator a choice of
infinitely variable speeds from 0 to 8 mph forward, and 0
to 4 mph in reverse. Avoid excessive H I G H travel speed
whenever possible. Lower travel speeds are best for most
jobs such as snow casting or mowing.
It is required that the tractor operate at F U L L
T H R O T T L E . While operating under heavy load conditions,
listen to the engine R P M . If the engine begins to labor, d o
n o t a d v a n c e t h e t r a v e l p e d a l . By letting up on the travel
pedal, the ground speed will decrease and the engine speed
will increase, thereby allowing engine to maintain constant
P T . O . speed.

The travel (control) pedal is generally used for dynamic
braking. T o slow down or stop the tractor while it is in
forward motion, gradually apply pressure to the travel
control pedal with heel of right foot until tractor comes
to a full stop. T o slow down or stop the tractor while it
is in reverse motion, apply pressure to travel control pedal
with toe of right foot until tractor comes to a full stop.
If transmission " H O T L I G H T " comes on reduce draw bar
loading. D o n o t o v e r c r o w d t r a c t o r .
To move about manually, turn " F r e e Wheeling V a l v e " on
Hydrostatic about one half turn counterclockwise to open.
See Figure 12. Tractor can then be pushed. Push on the
Right side of tractor so foot brake pedal can be used to
stop tractor.
