A dual seat arrangement for an earthworking vehicle consists of a first seat including a seat cushion fixed to the vehicle body and a backrest pivotally supported on the vehicle body about a generally horizontal first pivot axis. A second rearwardly facing seat is pivoted on the vehicle body about a second parallel horizontal axis and the backrest and second seat are interconnected by a rigid link so that the two move as a unit between generally horizontal and generally vertical positions which respectively define the operative position for the rearwardly facing seat and the operative position for the forwardly facing backrest. A single releasable latch means is utilized for defining the upright position while the generally horizontal position is defined by supporting the seat directly on the vehicle frame structure.

Dual seat for material handling equipment

A combination low ground pressure, low turning resistance, and self-cleaning shoe for an articulated endless track used on track-type vehicles is disclosed. The shoe is formed as a rigid body having a sloping forward planar surface and a sloping rearward surface which each run the length of the shoe and which substantially converge toward each other. Projecting from between the forward and rearward surfaces is a third surface, or traction lug. High-floatation planar bearing surfaces are located on each end of the body and each have a portion adjacent to, and of the same width as the traction lug but increase in width with increasing distance from the lug.
