How Four-Speed Winches Work

They look innocent enough—in fact they look almost identical to other two-speed winches. But that’s where the similarity ends. Pontos four-speed winches revolutionize the winch operation by use of a clutch and trigger mechanism that allows seamless—and intuitive, with a simple change of direction in the winch handle--engagement of two extra gears. The patented trigger mechanism moves up and down in the drum housing to engage the clutch; as load decreases the clutch automatically moves back down. This clutch system provides two additional speeds. In the Grinder those speeds are put to use to provide faster line handling; in the Trimmer those gears are used to provide more power for the same winch size when handling lines.
