C. Foot Throttle
The foot throttle is interlocked with the hand throttle.
Depressing the foot throttle increases the engine
speed. Full engine speed control can be obtained
with the foot throttle if the hand throttle is in the full
rearward (slow) position. The foot throttle may also be
used to temporarily increase the engine speed above
the hand throttle setting.
D. Main Shift Lever
WARNING: Never shift the main shift
lever without first disengaging the
tractor’s clutch by depressing the clutch
pedal. Failure to do so will result in
severe damage to the transmission.
The main shift lever allows you to shift the tractor’s
transmission into any of four gear sets. Each gear set
represents a change in tractor speed, with 1 being the
slowest speed and 4 the fastest. The synchromesh
type gearbox allows you to change gears without
stopping by just fully depressing the clutch pedal.
The shift pattern is in the form of an "H" with the cen-
ter position being neutral. See Figure 13.

E. Hi-Lo Range Shift Lever
WARNING: Never shift the Hi-Lo range
shift lever without first disengaging the
tractor’s clutch by depressing the clutch
pedal. Failure to do so will result in
severe damage to the transmission.
The Hi-Lo range shift lever allows you to shift the trac-
tor’s transmission into any of three speed ranges (See
Figure 14).
To shift into the High, Middle, or Low range, com-
pletely stop the tractor and fully depress the clutch
pedal.
Move the lever to the left and forward to shift into
the High (faster) range.
Move the lever to the left and rearward to shift
into the Middle (medium) range.
Move the lever to the right and rearward to shift
into the Low (slower) range.
Move the lever to the center position to place in
neutral.
Figure 14
Use in combination with the main shift lever and the
forward/reverse lever to obtain twelve speeds in for-
ward and twelve speeds in reverse
F. Auxiliary Hydraulics Lever
Use this lever to control the cylinder positions of
optional implements attached to the remote hydraulic
outlets of the tractor.
IMPORTANT: Do not hold the lever in the "Pull" or
"Push" position once the remote cylinder has reached
the end of its stroke. Doing so will force oil through
the relief valve, and over a prolonged period cause
the hydraulic oil to overheat.
