ABSTRACT:
A prop assembly including an elongated prop leg is provided having one end pivotally mounted to an associated vehicle dump bed for swinging movement between a first generally horizontal retracted position when the dump bed is in its lowered position and a second depending operative position with one end of the leg inclined downwardly when the load bed is in a raised inclined dumping position. Structure is provided for limiting swinging movement of the leg toward its lowered operative position with the leg angularly displaced relative to the bed less than that angular displacement from the retracted position of the leg which would allow the leg to depend vertically downwardly from the bed. The lower end of the leg is positioned, when the bed is lowered from the raised limit position thereof to an intermediate position between the raised and lowered limit positions and the leg is in its lowered operative limit position, for automatic engagement with a leg locating and seat structure provided on the frame of the associated vehicle to establish a partially raised position of the load bed in which the latter is propped through utilization of the prop leg.
