Adjustable track suspension

A tracked vehicle comprising:

• a frame having a longitudinal axis;
• at least one track suspension, the track suspension including:
• an endless track;
• a rotatable drive wheel engaged with the endless track and configured for driving the endless track;
• a nonrotatable wheel support configured for supporting the drive wheel;
• a rotatable drive wheel shaft having a length, rotationally engaged with the drive wheel, and configured for driving the drive wheel in rotation;
• and
• a nonrotatable drive wheel shaft support configured for supporting the drive wheel shaft in rotation and steerably coupled to the frame;
• wherein the wheel support is adjustably securable to the drive wheel shaft support in a plurality of laterally disposed positions and the drive wheel is slidingly positionable with respect to the length of the drive wheel shaft in correspondence with the adjusted position of the wheel support, the laterally disposed position of the track suspension with respect to the longitudinal axis being thereby adjustable.

A method of adjusting the track width of a tracked vehicle, the method including the steps of:

• unfixing a wheel support of a track suspension from a drive wheel shaft support of the vehicle;
• adjusting the lateral location of the wheel support, and thereby of the track suspension, from a first position to a second position with respect to the drive wheel shaft support;
• and
• affixing the wheel support of the track suspension to the drive wheel shaft support.
