An oscillation stop mechanism for use in conjunction with a compound steering mechanism adapted for use on a compact tractor is disclosed wherein an elongated stop link is positioned on opposing sides of the steering axis about which the pivoted axle rotates to effect a compound steering action as a function of the amount of steering movement of the steerable wheels. The elongated stop links are provided with upper and lower cupped flanges that are engageable with corresponding upper and lower brackets affixed, respectively, to the chassis and the front axle to stop the pivotal movement of the front axle about its oscillation axis. The upper flange on each stop link is positionally adjustable along the length of the stop link for selectively varying the linear distance between the upper and lower flanges and, thereby, vary the amount of permissible oscillation of the front axle relative to the chassis.

An oscillation stop apparatus for a tractor having a chassis; a front axle pivotally connected to said chassis for pivotal movement about a generally vertically extending steering axis, said front axle having laterally spaced steerable wheels pivotally mounted on the opposing ends thereof, said front axle also being pivotable about an oscillation axis to permit one of said steerable wheels to be positioned at a higher elevation than the other steerable wheel; and a steering mechanism operatively coupled with said steerable wheels to control the pivotal movement thereof and to effect a pivotal movement of said front axle about said steering axis, comprising: a pair of laterally spaced upper brackets affixed to said chassis; a pair of laterally spaced lower brackets affixed to said front axle and corresponding, respectively, to said upper brackets, said lower brackets being movable relative to said upper brackets in both a generally vertical direction and along an arcuate fore-and-aft direction centered on said steering axis; and a pair of laterally spaced stop links interengaged with the respective corresponding upper and lower brackets, each said stop link having an upper stop limit engageable with the corresponding upper bracket and a lower stop limit engageable with the corresponding lower bracket, each said stop link restricting the pivotal movement of said front axle about said oscillation axis whenever the linear distance between corresponding upper and lower brackets is equal to the linear distance between the corresponding said upper and lower stop limits, at least one of said stop limits being adjustable for selectively varying the linear distance between said upper stop limit and the corresponding said lower stop limit.
