Abstract
A bulldozer assembly comprises a pair of laterally spaced push arms pivotally interconnected between a blade thereof and a vehicle. A pair of lift cylinders are also pivotally connected between the vehicle and the blade for selectively raising or lowering the blade relative to the vehicle. A tilt mechanism for selectively tilting the normally upright blade in a vertical plane comprises first and second members each pivotally interconnected between the vehicle and the blade on an outboard side thereof. A double-acting cylinder is pivotally interconnected between inboard sides of the members for selectively pivoting the members relative to each other to tilt the blade.
