Bushing removal adapter

A seat support prop for use with a retractable seat assembly. The prop is arranged to support the seat in a retracted position such as for providing access to the space normally below the seat. The prop includes a latch pin received in a guide slot of a mounting element of the retractable seat assembly. The slot includes an intermediate transfer portion obliquely related to a guide portion thereof in which the pin is received when the seat is in the seating position. The slot is generally U-shaped with the transfer portion defining the bight thereof and extending at a substantial angle to the horizontal when the seat is in the seating position. The guide portion extends at a small angle to the horizontal when the seat is in the seating position. The latching portion extends generally perpendicular to the transfer portion. The prop structure requires that the seat assembly be moved beyond the retracted position both to effect the latching thereof and the release thereof in the selective positioning of the seat assembly.

Seat support prop

A track-type vehicle comprises a plurality of articulated track shoes each comprising a pair of downwardly converging sidewalls terminating at a grouser extending the full width thereof. The sidewalls define a V-shaped trough-like configuration and a track link is releasably attached thereto. A pair of parallel lugs are formed on the upper ends of the sidewalls.

Low ground pressure track shoe

A track-type vehicle, such as a crawler tractor, comprises a pair of endless track assemblies mounted on either side thereof. Each track assembly is entrained over a sprocket and a striker bar is secured on a frame of the vehicle and extends outwardly in close proximity to the sprocket and track assembly for breaking-up material carried by the track assembly thereby.
