ABSTRACT:
Tilt linkage and lift arm systems by way of which implements including buckets, backhoes, grapples and forks and the like are mounted with respect to conventional load lifting vehicles including tractors, loaders, forklifts, bulldozers and the like wherein the tilt linkage members form at least two parallelograms having a common link through the lift arm(s) whereby the systems continuously and automatically level the implement as it is raised or lowered unless the tilt linkage is activated to change the pitch of the implement relative to the vehicle. In some embodiments more than one set of two or more parallel tilt linkages may be connected in end to end relationship between the vehicle and the implement.
