Abstract
An undercarriage for an agricultural machine includes a hollow axle, and a stub axle slidably received within the hollow axle. A lock arrangement locks a longitudinal position of the stub axle relative to the hollow axle. At least one shim is positioned at an outboard end of the hollow axle to adjust the distance between said stub axle and said hollow axle.
Claims21
An undercarriage for an agricultural machine, said undercarriage comprising:
- a hollow axle having an outboard end and an inboard end;
- a stub axle slidably received within said hollow axle and configured for extending to an extended position which determines an extended wheel stance of the undercarriage;
- a lock arrangement for locking a longitudinal position of said stub axle relative to said hollow axle;
- a plate permanently mounted to an interior, bottom surface of said hollow axle and located at a distance away from the outboard end of said hollow axle which corresponds to said extended wheel stance, and proximate to the inboard end of the stub axle;
- and
- at least one adjustment device positioned at a top face of said stub axle and at the outboard end of said hollow axle to adjust a distance between said stub axle and said hollow axle such that said stub axle tilts about said plate.

An agricultural machine, comprising:
- a chassis;
- and
- an undercarriage mounted to said chassis, said undercarriage including:
- a hollow axle having an outboard end and an inboard end;
- a stub axle slidably received within said hollow axle and configured for extending to an extended position which determines an extended wheel stance of the undercarriage;
- a lock arrangement for locking a longitudinal position of said stub axle relative to said hollow axle;
- and
- a plate permanently mounted to an interior, bottom surface of said hollow axle and located at a distance away from the outboard end of said hollow axle which corresponds to said extended wheel stance, and proximate to the inboard end of the stub axle;
- and
- at least one adjustment device positioned at a top face of said stub axle and at the outboard end of said hollow axle to adjust a distance between said stub axle and said hollow axle such that said stub axle tilts about said plate.

A method of adjusting an angular orientation of a wheel on an agricultural machine, comprising the steps of:
- providing an undercarriage configured for mounting to the agricultural machine, said undercarriage including a hollow axle having an outboard end and an inboard end, a stub axle slidably received within said hollow axle and configured for extending to an extended position which determines an extended wheel stance of the undercarriage, a lock arrangement for locking a longitudinal position of said stub axle relative to said hollow axle, and a plate permanently mounted to an interior, bottom surface of said hollow axle and located at a distance away from the outboard end of said hollow axle which corresponds to said extended wheel stance, and proximate to the inboard end of the stub axle;
- sliding the stub axle within the hollow axle to a desired wheel stance;
- adjusting a longitudinal spacing between the stub axle and the hollow axle;
- adjusting a lateral spacing between the stub axle and the hollow axle with an adjustment device located at a top face of said stub axle and at the outboard end of the hollow axle such that said stub axle tilts about said plate and an angle of said stub axle is adjusted to adjust said angular orientation of the wheel;
- and
- fixing the stub axle relative to the hollow axle at the adjusted longitudinal spacing by locking the longitudinal position of the stub axle relative to the hollow axle, using the lock arrangement, said lock arrangement includes at least one bolt extending through aligned holes in each of the hollow axle and the stub axle.
