This shock absorber controls the damping rate of the three-point linkage on the host tractor. It is mounted on the chassis and connects the lift arms to the tractor frame, absorbing oscillations from the implement load during transport and field work. A worn or leaking shock absorber allows uncontrolled bouncing of the linkage, which reduces hitch stability and can cause uneven depth control of the attached implement. The part is manufactured to the original spring and damping curve specifications, so it maintains the same compression and rebound characteristics as the factory assembly. No shimming or bracket modification is needed during replacement.
