The rate-of-drop/lock valve controls the rate of rockshaft drop when rockshaft control lever is operated. This valve provides direct rate-of-drop control for 3-point hitch mounted implements. the valve can be used to hydraulically lock rockshaft from lowering (3-point hitch) in a desired position. The tractor can be operated with rate-of-drop/lock valve closed. The rockshaft can be raised with the rate-of-drop/lock valve closed.

Increase Rate-of-Drop: Rotate rate-of-drop/lock valve knob (A) counterclockwise to make drop faster.

Decrease Rate-of-Drop: Rotate rate-of-drop/lock valve knob (A) clockwise to make drop slower.
