Abstract: A support frame for supporting a blade on a machine is provided. The support frame includes a lower frame section including a first leg, a second leg and a transverse portion that extends between the first leg and the second leg. Each of the first and second legs has a respective end portion and the transverse portion carries a lower connecting element configured to connect to a blade. An upper frame section includes a first leg, a second leg and a transverse portion that extends between the first leg and the second leg, each of the first and second legs having a respective end portion. The end portions of the respective first legs of the lower frame section and the upper frame section are connected together and the respective transverse portions of the lower frame section and the upper frame section are spaced from each other.

Abstract: A differential assembly for a machine includes a ring gear, first and second differential side gears and a plurality of pinions configured to mesh with the first and second side gears, and mounted on at least one pinion support pin. An inner differential housing is rotatably supported by an outer differential housing, and includes a torque transmitting hub configured to couple the ring gear with the first and second side gears via at least two pinions. The hub including a plurality of radial spokes and an outer rim portion having pinion support pin bores therein.

Abstract: A drive sprocket assembly for driving an endless chain assembly for propelling a machine has a hub portion and flexible cantilever teeth in which each tooth is separately deflectable upon impact by a bushing of the endless chain assembly. The flexibility of each tooth will absorb a portion of the kinetic energy of the impact to reduce noise in the structure. The drive sprocket assembly includes a plurality of segments each having the cantilever teeth. Each segment has a first end portion and a second end portion having an end relief which prevents wear between the segment and the hub as the end portion is deflected by the impact.
