SPECIFICATIONS
Hydrostatic Drive System
Type Front-wheel drive. (14.769:1 planetary)
Transmission Axial piston variable rate high torque
hydrostatic pump directly coupled to
engine; variable rate hydraulic motor drives
axle through 2-speed transfer case. This
transmission is controlled using automotive
control, (using an electronic foot pedal, as you
depress the pedal the engine RPM increases,
the node 3 computer is monitoring the engine
RPM as it is increasing, the computer will start
to stroke the hydrostatic pump causing the
chip spread to move, the higher the engine
RPM the more the hydrostatic pump is stroked
for higher speeds. Once the Hydrostatic
pump reach full stroke, the pump controller
continues to increase in pressure which than
starts to de-stroke the hydrostatic motor for
more speed eventually reaching full speed of
1675FPM (510MPM) / 19MPH (30KPH). Also
the automotive control has HP / anti-stall
control; if the chip spreader encounters is high
load and the engine RPM’s drop more than
300RPM from what the computer thinks they
should be, the computer will start to de-stroke
the hydraulic pump so as not to stall the diesel
engine, this system allows the chip spreader
to operate at 95% plus engine torque. NOTE:
the automotive control system is measuring
engine RPM off the tachometer signal on the
alternator, if you chip spread slows down you
may have belt slippage, inspect and replace
belt as needed.
Transfer Case 2-Speed, high (1.613:1) and low range (4.14:1),
air shift.
Operating Mode LOW Range (0-600 FPM) (Low-Lock engaged,
0-300 FPM).
HIGH Range (0-1600 FPM) (18 MPH) (Low-Lock
engaged, 0-700 FPM).
NOTE: In low range the unit will pull a fully
loaded 15 cubic yard dump truck up a 15%
grade from a dead stop.
Diesel Engine Cumins QSB 6.7 liter, Tier-3, 275 HP @ 2300
