Drive
Transaxle
SF45 two-speed powershift transaxle is a single unitized driveline designed for reliability under medium load and severe operating conditions. The transaxle features electric shift control that provides smooth engagement on start-up and on-the-fly shifts between low and high range. Electric shift control eliminates linkage wear and adjustment. A transmission oil cooler located in the engine radiator extends transaxle life. Full-floating drive axle design adds durability as only torsional forces, not truck loads, are transmitted through the axle shafts. Service is enhanced by a readily accessible transaxle control cover and spin-on, full-flow lubricant filter.
Brakes
Hydraulic-operated wet disc brakes provide excellent brake performance and extended brake life. Brakes can be actuated from either left or right foot pedals. Left foot pedal also provides inching control. Disc/caliper-type parking brake on transmission is left hand-operated, and operator adjustable. Brake system reservoir is easily accessed on the front cowl.
Steering
Heavy fabricated steer axle incorporates an integral double-acting steer cylinder providing equal steering rate. Single-piece steer knuckles supported by tapered roller bearings provide high durability with low maintenance requirements. Full hydrostatic operation reduces mechanical links and eliminates kick-back. The axle is mounted in "silent block" cushion mounts that absorb shock and improve comfort. They require no maintenance.
Hydraulic System
The main hydraulic pump is direct driven by the engine crankshaft, providing reliability and separation from engine heat. Full-flow filter is located in the hydraulic tank providing continuous filtration. Hydraulic tank cover incorporates return line fittings, dipstick, and breather filter connection. Adjustable hydraulic valve eliminates unnecessary oil flow, energy loss and heat generation. Integral twin-frame hydraulic tank dissipates hydraulic oil heat. Fluid capacity 17.1 U.S. gals. (65 L).
