A traction wheel for a track roller unit of an agricultural working machine has at least one drive wheel for driving an elastic track belt of the track roller unit. The at least one drive wheel comprises supporting arms which extend from an axis of rotation of the drive wheel in the radial direction in the manner of spokes and a gap is formed radially on the outside, at least between two adjacent supporting arms in each case. At least one friction element is situated, in particular detachably, radially outwardly on a supporting arm for non-positive interaction with the track belt.

A sprocket wheel, which is an example of the machine component, includes a base made of a first metal, and an overlay disposed in contact with the base to cover at least a part of a surface of the base. The overlay includes a matrix made of a second metal, and hard particles dispersed in the matrix. The surface of the overlay is a forged surface. The hard particles located in an overlay surface region within an average particle diameter of the hard particles from the surface of the overlay are arranged side by side while being embedded in the overlay.

A track support member and drive assembly are disclosed. The drive assembly includes the track support member, an axle housing, driveshaft, hub, drive wheel, track drive frame, rollers and track. The driveshaft extends through the axle housing. The track support member is connected to the axle housing, and the driveshaft extends through the track support member. The hub rotates with the driveshaft, and the drive wheel. The drive frame is connected to the track support member, and the rollers are connected to the drive frame. The track is connected to the drive wheel and rollers. Rotation of the driveshaft rotates the hub and drive wheel which rotates the track about the drive wheel and rollers. The track support member can be a single integrated piece including an attachment ring for connecting to the axle housing, and undercarriage support arm(s) for connecting to the track drive frame.

A work machine includes a frame including an axle and an arm, a track undercarriage assembly including an undercarriage assembly connected to the arm, a drive assembly operably attached to the axle, and a track belt mounted on the drive assembly. The undercarriage assembly and the drive assembly are each configured for lateral adjustment relative to a longitudinal centerline of the frame from a first position to a second position. The drive assembly includes a drive sprocket that is assembled with the axle in a first configuration to laterally adjust the drive assembly towards the first position and a second configuration to laterally adjust the drive assembly towards the second position. The undercarriage assembly includes an undercarriage frame attached to the arm, wherein the undercarriage frame and the arm are adjustably coupled to allow the undercarriage frame to be movably adjusted between the first and the second positions.

A lug is configured to be attached to a projection of a sprocket using a retaining mechanism, the lug comprising an enclosure including a bottom surface defining an aperture configured to receive the projection, and a side surface defining an aperture configured to receive a retaining mechanism.

A track drive for outdoor power equipment has a support frame with a centerline and a hub bearing attached to the support frame. A drive sprocket having a nesting interior half and exterior half is attached to the hub bearing, which enables the drive sprocket to rotate relative to the support frame. The drive sprocket is attached to an associated drive hub of a piece of outdoor power equipment. Drive sprocket teeth are spaced radially about the drive sprocket, with a first set of drive teeth attached to the interior half sprocket and located on an interior side of the support frame. A second set of drive teeth are attached to the exterior half sprocket and located on an exterior side of the support frame. The drive sprocket transmits a rotational force to an endless track to rotate the endless track and propel the outdoor power equipment.
