Abstract
A sheet-feed tractor is provided with raised land portions adjacent its drive and idler wheels. The raised land portions are positioned on the chassis of the tractor and shaped to form wall surfaces that are in radial registration with borders on a drive belt trained around the drive and idler wheels. The wall surfaces provide a positive means for preventing outward movement of the drive belt off the drive wheel and therefore prevent their disengagement.
