Abstract
A small loader has a central body that is formed as a unitary frame that has spaced apart side walls. The body is supported on drive and support units that are independently assembled, and have mounting plates that bolt to the exterior of the respective side walls of the body when the loader is to be assembled. The mounting plates support a framework for mounting spaced rotatable members, as shown members that mount a drive track for propelling and supporting the body. In one form a separate track drive sprocket is positioned above a slidably mounted track idler that creates a tension in the drive track.
