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.

Provided is a track drive for outdoor power equipment including a support frame and a drive axle configured to attach to an associated drive hub. A hub bearing is mounted on the drive axle and the support frame enabling the drive axle to rotate relative to the support frame. A drive sprocket is attached to the drive axle and includes an interior half sprocket and an exterior half sprocket. The half sprockets are located on either side of the support frame. Drive teeth are spaced radially about the drive sprocket. The drive sprocket is movably engaged with an endless track to transmit force to rotate the endless track and propel the outdoor power equipment. A kit for adding or replacing a track drive of outdoor power equipment is also provided.

A crawler traveling device includes a sprocket and a rubber crawler. The sprocket is provided with a wheel portion that is mounted to a driving axle and tooth portions. The tooth portions are provided at side portions of the wheel portion, spaced apart in a sprocket circumferential direction. The rubber crawler is provided with a rubber body that is wrapped round the sprocket, a wheel portion support face that is provided at an inner periphery portion of the rubber body, and engaging recess portions. The engaging recess portions are provided, spaced apart in a crawler peripheral direction, at each of two crawler width direction side portions of the inner periphery portion to sandwich the wheel portion support face. The engaging recess portions are recessed toward the crawler outer side and the tooth portions can be inserted into and engaged with the engaging recess portions.

A vehicle track system and assembly for outfitting vehicles for mobility in off-road conditions. Snow, mud, muck, soil, sand, ice, and other fickle conditions are more readily traversed. In an implementation, a spindle, a first driver, a drive sleeve, a second driver, and a single track are all part of the vehicle track assembly. Multiple of these components of the vehicle track assembly are furnished with one or more clocking indicia. The clocking indicia serves to provide rotational alignment indications amid assemblage procedures of the components of the vehicle track assembly. Proper timing of the drivers with respect to each other and attendant engagement with the single track is hence facilitated. Binding or other shortcomings observed with improperly-timed drivers is more readily resolved.
