Abstract: A method for mitigating powertrain abuse on a grade can include determining the grade a machine is on, the machine including an impeller clutch located between an engine and a powertrain so as to connect and disconnect engine power from the powertrain; and if the grade is over a threshold, a controller ignores any operator input to the impeller clutch such that machine speed retarding is utilized to keep the machine at a proper speed.

Abstract: A differential assembly is disclosed, including a housing forming an interior space, and a shaft may extend into a portion of the interior space of the housing. A side gear including an aperture may be arranged within the interior space and an end portion of the shaft is aligned and extends through the aperture. The differential assembly may further include a sliding sleeve configured with a flat flange portion, the sliding sleeve may extend through the aperture and slide over the end portion of the shaft. Furthermore, a pinion gear may be configured with a flat face portion and a pinion gear cam portion may be configured to extend axially away from the flat face portion of the pinion gear. An actuator may actuate the sliding sleeve between a sleeve first position and a sleeve second position and the flat flange portion may interact with the pinion gear cam portion.

Abstract: A differential assembly for a drive train having a first axle shaft and a second axle shaft is provided. The differential assembly includes a differential gear set, a first pinion gear disposed on the first axle shaft, a second pinion gear disposed on the second axle shaft, each of the first pinion gear and the second pinion gear being in meshing engagement with the differential gear set, and a differential locking arrangement mounted on at least one of the first axle shaft and the second axle shaft. The differential locking arrangement is adapted to selectively lock the first axle shaft with the second axle shaft.
