This model is a lightweight, reliable winch that stands out with a new feature that provides added control over the movement of loads - the quick release automatic anti-rollback mechanism, or ARM. Equipped with a centrifugal clutch, the drum does not immediately start turning at the start of the engine. After wrapping the rope on the drum a few times, insert it in the cam cleat, pass it on the exit guide and pull on it when the time comes. This engages the clutch and the winch starts pulling. Once the tension is released, the drum stops turning and the anti-rollback mechanism holds the load in position. Note: the ARM rope grabbing system cannot be installed on other pulling winches.
