Features of the WETHERELL TOP LINK include: Ability to tilt your quick hitch back and forth from the tractor cab when hooking up to unleveled implements. Increase or decrease implement angle when cultivating, as soil type varies from one end of the field to the other. The TOP LINK hydraulically locks cylinder in place with the check & counter balance valve, designed to avoid drifting in or out even in the event of a ruptured hydraulic hose. Make adjustments ON THE GO with easy to read ruler type cylinder stroke gauge for accurate adjustment from the tractor seat.
