The PCW4000 Pulling Winch has a quick release automatic anti rollback mechanism (ARM) that allows the user to control and hold a load flawlessly while winching. As soon as the rope is pulled that goes through the ARM, the centrifugal clutch activates and the winch begins to pull. As soon as the rope is released, the drum stops rotating and the automatic mechanism does its job by holding the load in position! Disengage the rope in one simple movement! The Honda 4-Stroke GX50 360° inclinable engine offers high output and light weight with excellent fuel efficiency. It is the first Honda four-stroke model in the two-horsepower class that is 360-degrees inclinable during operation and storage. The PCW4000 develops a remarkable pulling force of 2,200 lb. without mechanical advantage. By adding a pulley system, you can go up to five times (5x) the pulling force.
