Abstract
A steering cylinder for a tractor with internal, adjustable steering stops that do not occupy packaging space beyond the cylinder itself. End caps of the cylinder, between the piston rod and the cylinder, serve as the stops. The end caps are threadably mounted in the cylinder to enable adjustment. The stops can be rotated relative to the cylinder to thread the stops in or out, thereby changing the stroke of the steering cylinder. Once the stops are set to the desired location, they are held in place by a retainer that is bolted to the cylinder. The retainers can be selectively removed from the cylinder and then used as a wrench to rotate the stops to adjust the cylinder stroke. Adjustment is needed when different wheel and tire combinations are mounted on the tractor or when the tread width is changed. A travel limiter is mounted to the cylinder to prevent complete withdrawal of the stops and the resulting loss of hydraulic oil.
