This overrun coupler or clutch attaches to your tractor's PTO shaft and to the drive shaft of the implement that is being hauled.
This PTO coupler has a 1-3/8 inch diameter 6-spline male end and a 1-3/8 inch diameter 6-spline female end.
This overrunning clutch allows the PTO shaft to rotate in one direction, but also to spin freely the opposite way. This works to
control the speed of the implement that is being hauled behind the tractor. By doing so, the implement does not exceed the
tractor's speed when the tractor is slowing down. This PTO overrun clutch has a male and female end, each with 6 splines.
