Abstract
An adjustable ratcheting wheel hub comprising a reversing pawl driven wheel hub, an axle containing a plurality of pin receiving apertures, a bearing cover assembly, and a hub tube. The hub tube operationally connects the axle to the pawl driver and contains a pin receiving aperture such that the hub tube slidably engages the axle and is secured to the axle by means of a locking pin through the hub tube and axle. The axle contains a plurality of pin receiving apertures and the width between the wheels is varied by selecting the pin receiving axle aperture that corresponds to the desired width.

An improved ratcheting wheel hub having a pawl driven wheel hub, a pawl carrier housing a double end reversing pawl for rotational engagement with said wheel hub, means for reversing rotation of said pawl and said wheel hub, a bearing cover to cover said pawl carrier, and an axle operationally connected to said pawl carrier, wherein the improvement comprises means for selectively detachably mounting said pawl carrier at a plurality of positions on said axle so as to selectively vary the axial distance betwen two wheels, and means for maintaining said bearing cover in a stationary non-rotational position against said pawl carrier.
The combination of a wheeled tractor comprising a frame, a drive axle rotatably secured to said frame, a power means on said frame operatively secured to said drive axle, wheel drive hubs mounted to the ends of said axle, and wheels secured to said axle, the invention comprising:
- first means for slidably mounting said drive hub on said axle, second means for selectively locking said drive hubs at
- predetermined positions on said axle, said drive hub including a bearing cover and a rotatable drive assembly,
- and means for slidably connecting said bearing cover to said frame and for holding said bearing cover against rotation with said drive assembly.
