A debris deflector includes an at least partially annular body defining a central axis, a radial direction, and a circumferential direction about the central axis. The at least partially annular body includes an outer radial extremity defining surface, an inner radial extremity defining surface, a first circumferential extremity defining surface, and a second circumferential extremity defining surface. A first deflection surface extends from the first circumferential extremity defining surface, and defines a first surface normal that points away from the central axis.

A seal assembly for sealing a lubricant space that is formed between a pin, a track shoe pressed-on onto one end of the pin, and a sleeve of a track. The sleeve is pushed onto the pin and is swivelable on the pin. The track further includes at least one second track shoe pressed onto one end of the sleeve. The seal assembly provides a first seal ring for sealing the lubricant space between the sleeve and the first track shoe, and an elastic ring for applying pressure to the first seal ring. The seal assembly further provides a second seal ring for sealing the lubricant space between the sleeve and the first track shoe and/or the pin.

The present invention is related to a track unit for a vehicle, such as an agricultural harvesting combine. The track unit according to a first embodiment of the invention comprises one or more bogies arranged between front and rear guide wheels. The bogies are provided with wheel pairs that are rotatably arranged about a longitudinal axis of the bogie itself, and are thereby capable of adapting individually to transversal oscillations caused by the terrain. Preferably, the bogies are furthermore equipped to adapt to longitudinal oscillations as well, by the longitudinal portion of the bogie being rotatable about a transversal axis. According to a second embodiment, the track unit of the invention is equipped with a cutter, non-rotatably mounted on one or both outer faces of the rear guide wheel, in a position where said wheel is in direct contact with the track, the cutter being configured to cut crop material that is transported upwards between the rear guide wheel and the track when the track unit moves forward.

The present invention relates to a drive sprocket member for a drive wheel member of a tracked vehicle. The drive wheel member is rotatable about a centre axis for rotating an endless track. Said drive sprocket member comprises a set of tooth members arranged around the circumference of said drive sprocket member, and a ring-shaped support member for said tooth members. Said tooth members are, in an operation position, configured to project from the ring-shaped support member in a main direction essentially parallel to the axial direction of said centre axis. Said tooth members are arranged in connection to said ring-shaped support member and shaped so as to provide resilient properties in the radial direction such that, if a tooth member is subjected to a radial force exceeding a certain threshold, said tooth member is configured to deform relative to its operation position.

A greasable axle and hub kit assembly and method of installing the greasable axle and hub kit assembly in the frame of a continuous tread machine is provided. The greasable axle and hub kit assembly utilizes at least an inner seal, greased bearing, an anti-spin washer, a fastener, an outer dust cap, an inner seal protector, and an outer seal protection cap to provide for an axle and hub kit assembly with an improved lifetime and a reduced chance of blowouts. The greasable axle and hub kit may further comprise a coupled grease zerk for applying grease to the interior of the hub portion, providing lubrication to the interior components. The greasable axle and hub kit may even further comprise a pilot flange for attaching wheels of varying sizes and materials to the greasable axle and hub kit.

A ground-engaging track system includes a track roller having a roller shell with an outer tread surface, and a roller shaft supporting the roller shell for rotation and cantilevering the track roller to a track roller frame. The track roller is positionable in the track system to contact only one of a first track rail or a second rail in a ground-engaging track.

A tracked undercarriage roller assembly including a roller body having a through cavity delimited by a radially inner surface, a shaft in the through cavity, a bushing extending from a first axial end to a second axial end and radially interposed between the roller body and the shaft, an annular chamber at least partially filled with a lubricant and radially interposed between the shaft and the bushing, a housing seat in the shaft including an inlet portion facing an axial end surface of the shaft and a measuring portion inside the shaft in an axial position between the first and second axial ends of the bushing, wherein the inlet portion and the measuring portion are aligned along an axial direction. A temperature transducer is inside the housing seat at the measuring portion, wherein the measuring portion is at a radial distance from the bushing between 8 millimetres and 50 millimetres.
