The Cummins-powered Case 921C features electronic control of its torque-sensing "autoshift" transmission and uses hydraulically actuated, maintenance-free, multiple-wet-disc brakes (with an accumulator) at all four wheels.

Number of models: 1

New models: 921C

Product-line features: The 921C uses a tandem vane-type hydraulic pump that delivers 68 gpm at 2,850 psi to the loader implement hydraulic system. The open-center control valve can be equipped with up to four spools, including those for auxiliary functions. Electromagnetic detents are used in the float, raise and rollback circuits.
