Claim:
1. A rigid implement frame comprising: at least one rigid lateral beam having an inner beam end rigidly attached to an inner portion of the implement frame, the at least one lateral beam extending from the inner beam end outward to an outer beam end; a hydraulic cylinder having a first end connected to a front inner portion of the implement frame forward of the inner beam end, and a second end connected to an outer portion of the lateral beam; a hydraulic source operative to supply hydraulic fluid to the hydraulic cylinder at a bias pressure such that the hydraulic cylinder exerts a bias force urging the outer portion of the lateral beam toward the front inner portion of the implement frame, and the hydraulic source operative to allow hydraulic fluid to flow out of the hydraulic cylinder when a force is exerted on the hydraulic cylinder that is greater than the bias force.
