Oscillation stop mechanism for compact tractors

摘要

The mechanism comprises a pair of laterally spaced upper brackets affixed to the chassis, a pair of laterally spaced lower brackets affixed to the front axle and corresponding, respectively, to the upper brackets. The lower brackets are movable relative to the upper brackets in both a generally vertical direction and along an arcuate fore-and-aft direction centred on the steering axis. There are a pair of laterally spaced stop links interengaged with the respective corresponding upper and lower brackets, each 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 stop link restricts the pivotal movement of the front axle about the oscillation axis whenever the linear distance between corresponding upper and lower brackets is equal to the linear distance between the corresponding upper and lower stop limits. At least one of the stop limits is adjustable for selectively varying the linear distance between the upper stop limit and the corresponding lower stop limit.
