A nose construction spanningly connects the front ends of a pair of generally parallel linearly extending vehicle frame members. The construction comprises a tube extending from the front end of one to the front end of the other of the frame members and a pair of gusset structures unitarily formed of the tube, one adjacent each end thereof, each extending along the frame members towards a rear end thereof. The tube is affixed to the frame members. The gusset structure is also affixed to the frame members.

A scraping apparatus is provided for a track-type vehicle which has a track with a chain and shoes. The scraping apparatus has first and second scraping elements each having first and second opposed cutting edges. The first scraping element removes foreign material from the chain and the second scraping element removes foreign material from the shoes. The scraping apparatus removes foreign material during forward and rearward movement of the track.

Scraping apparatus for track-type vehicles

A drive mechanism having a steering clutch assembly, a brake assembly, and a final drive assembly housed within a unitary housing defined by separable steering clutch assembly, brake assembly and final drive assembly housings removably secured together. The individual housings define flanges which may be secured together to form the unitary housing. The secured flanges may, in turn, be secured to another support structure of the drive mechanism.

Drive mechanism having separable housing

A resilient push dozer arrangement includes a push dozer transversely disposed at one end of a vehicle and a push arm rigidly secured to and extended from the dozer in juxtaposition to a longitudinally extending mounting frame of the vehicle. The distal end of the push arm is attached to the mounting frame through a device which permits limited longitudinal movement of the dozer relative to the mounting frame. An apparatus for cushioning the longitudinal movement of the push dozer toward the vehicle is provided so that the shock loads applied to the dozer are cushioned thereby and transmitted to the mounting frame at a point widely spaced from the attachment device.

Cushioned push dozer device

Structure for mounting a bulldozer assembly to a vehicle, such as a tractor. The mounting structure includes lift jacks connected to a radiator guard extending about the vehicle engine coolant radiator. The mounting structure includes a portion connected to the lift jacks and a portion received in a socket provided in a corner portion of the radiator guard. The mounting structure includes structure for removably securing the same to the radiator guard.
