Abstract

The bowl assembly of a tractor scraper comprises a pair of laterally spaced sidewalls having a movable bowl portion pivotally mounted thereon to normally close an opening defined through a bottom of the bowl assembly. A double-acting cylinder, pivotally interconnected between one of the sidewalls and the bowl portion, is adapted to pivot the bowl portion to an open position. The cylinder is confined within the sidewall and is pivotally connected to the bowl portion via an arcuate slot formed through the sidewall. A sidewall of the bowl portion and a plate secured thereto function to continuously mask the slot during pivotal movement of the bowl portion between its open and closed positions.
