ABSTRACT:
A loader comprises a pair of lift arms pivotally mounted on a frame, and a bucket pivotally mounted on the forward end of the lift arms. A bucket tilt linkage, including at least one double-acting hydraulic tilt cylinder is operatively connected between the lift arms and the bucket to selectively position the bucket for various earth-working operations. The tilt linkage further includes improved linkage means for mechanically coupling sensed positions of an extensible rod of the cylinder across the pivot axis of the cylinder for enabling control means to respond to this condition independently of cylinder angular position.
