摘要： A guard for off road vehicles to protect the final drive area from debris which otherwise causes destructive abrasion and seal failure and particularly suited for the final drive of a track chain sprocket on a crawler. The guard encloses the space surrounding the final drive spindle housing and seal between the housing and a hub on which the sprocket is mounted. The guard can be safely installed on existing machines without disassembly of major parts of the final drive.

摘要： A final drive seal guard for a track-type tractor comprising a base component adapted to be stationarily fixed to the tractor and to surround a portion of a spindle housing of the final drive, a sprocket component adapted to be carried on and surround a portion of a sprocket hub of the final drive that rotates about an axis, and an intermediate component adapted to be bolted over the exterior of one of said base and sprocket components and surround portions of both of said base and sprocket components, the intermediate component and another of said base or sprocket components being mutually arranged to form a radially extending sealing gap at a potential path of debris into the guard at a location free of a relatively long axial gap upstream in said potential path.

摘要： Several embodiments of yieldable cutter blades are disclosed for use on a land vehicle to reduce the tendency of debris from being entrained and wrapped on rotary parts and their supports such as on wheels and axles or drive sprocket hubs and associated support housings. The blades yield in response to an excessive cutting force which could potentially damage support bearings for the rotary part in extraordinary conditions. In the various embodiments, a yieldable blade is retained in its operating position by a set of bolts of predetermined strength. When an excessive cutting force occurs, the bolts break away and permit the blade to yield away from its operative cutting position.

摘要： In a track-driven tractor, stationary cutter blades are fixed to a chassis of the tractor and cooperating rotating cutter blades are fixed to a sprocket hub of the tractor. The cutting blades are operable to cut refuse entrained between the sprocket and the chassis, which tends to wrap around the associated hub, so as to avoid the build-up of refuse on the hub which otherwise can lead to unnecessary wear of the sprocket, the hub, and an assembly forming a seal between the hub and the chassis, as well as unnecessary fuel consumption.

摘要： A cleat for compacting refuse at a landfill by use on the wheels of a compactor or on the shoes of a crawler-type tractor. The cleat has a prismatic modified Z or S configuration that affords superior compaction performance by increasing traction and thereby reducing churning of already compacted material. The flanges of the cleat create traction pockets on opposite sides so that the cleat is effective in either direction of the compactor or tractor.

摘要： A track pad for a crawler, especially operating in a landfill, having a generally rectangular base plate with holes for attachment to a track chain link, the base plate having front, rear and side edges, a high rise grouser on the base plate, the grouser projecting from the base plate a distance substantially greater than conventional grousers, the grouser having a central portion with the general configuration of a plate with an edge distal from the base plate, the central portion being generally laterally centered on the base plate, the grouser being devoid of areas projecting significantly from the base plate adjacent the side edges of the base plate.
