HYDROSTATIC DRIVE
POWER & SPEED CONTROL
The POSI-TRACK transmits the power from
the engine to the tracks using a hydrostatic
transmission. The hydrostatic transmission
sends oil under pressure to two individual hy-
draulic motors, one for each track. The hydro-
static transmission consists of two individual
hydrostatic pumps. One pump for each motor.
Track speed is increased by sending more oil to
the hydraulic motors, and power is increased by
sending less oil to the hydraulic motors. With a
mechanical transmission the operator must shift
down to increase power. With hydrostatic drive
the operator can simply pull back on the drive
controls, reducing speed and increasing power
at the same time.
ARE THERE GEARS?
No, not in the traditional sense. Hydro-
static drive offers an infinite amount of
gears
from 0 to full speed. The closer the
levers are to the neutral position the lower
the
gear
the vehicle is in.
ADVANTAGES
With hydrostatic drive there aren't any
clutches, brakes, or shift sticks to mess
with. Hydrostatic drive enables the opera-
tor to always find the right speed, and also
turn, counter-rotate and stop with ease and
precision.
GENERAL OPERATION
1 = MOST POWER and least speed
2 = LESS POWER and more speed
3 = MORE SPEED and less power
4 = MOST SPEED and least power
