HTG Series

Heavy Duty Integrated Transmission for Off-Highway Vehicles Up To 2500 LB. Gross Vehicle Weight (GVW), Consisting Of A Hydrostatic Pump, A Hydraulic Motor With Displacement Range of 238 to 310 CC/Rev, Oil, Filter, Reservoir, And Valving. Torque to 8180 lb-in, Side-Load to 4000 LB, Shaft 1.25 Inch.

The HTG Series Hydrostatic Transmission is manufactured with a 14 cc or 16cc pump and motor displacements up to 310 cc. These HT transmissions reduce the number of parts on a zero turn mower propulsion system from 72 to 2 parts requiring less installation and procurement labor, which provides increased customer efficiency.

The Integrated Hydrostatic Transmissions provide a compact, economical solution for the propulsion systems of off-highway vehicles up to 2500 pounds gross vehicle weight.

One integrated package contains the hydrostatic variable displacement pump, reservoir, filter and standard of the industry low speed, high torque motor eliminating dozens of additional parts reducing associated inventory and labor costs. The integrated Hydrostatic Transmissions perform with up to 10% more overall efficiency than competitive offerings. This means more horsepower to the mowing deck or other functions and more hill-climbing capability.

The HTG series transmission is a compact integrated product offering torques to 8180 lb-in, side load to 4000 lb., shaft size 1.25 inch, integrated pump/motor assembly featuring the industry-leading Torqmotor™ TG gerotor motor, integral charge pump, easy-to-service filter, fan and pulley included, integral reservoir (approx. 0.8 gal), easy fluid change and integral shock valves standard.

NOTE: Remote expansion tank required.
