One Aftermarket Add on Rotary Cutter Slip Clutch Easily Add a Slip Clutch to Your Splined PTO.

This listing is for one aftermarket independent adjustable slip clutch with a 1-3/8" by 6 spline male shaft and a 1-3/8" by 6 spline female end, Do you have a piece of equipment that is direct drive and wish it had a slip clutch to protect it or your tractor? Have you had to replace your gearbox or repair the PTO on your tractor because the direct drive PTO shaft between your tractor and equipment was overloaded and broke a shaft, damaged your gearbox or tractor? Have you found a good used mower, but it does not have a slip clutch and you wish is did? Are you running a piece of equipment designed for a lower horsepower tractor with a high horsepower tractor! Here is an easy way to add an adjustable slip clutch to your tractor or equipment without having to purchase a complete expensive PTO shaft! Just install this adjustable slip clutch directly on your tractor or implement, install your PTO onto the slip clutch, adjust the springs to match your protection needs and check to make sure that the PTO shaft has enough clearance as you slowly raise and lower your 3-point hitch with your tractors hydraulics and make sure the shaft doesn't bottom out causing the shaft to bend. If you need to shorten the shaft slightly to allow for proper clearance remove the shaft from the adjustable slip clutch, slide the two sides of the PTO apart and cut an equal a off each side as needed, reinstall the PTO shaft to the adjustable clutch and recheck for necessary clearance. Now just adjust the slip clutch to match your horsepower requirements making sure to consider both the horsepower rating of the mower and tractor and adjust the overall length of the clutch springs to match the corresponding rating on the provided clutch adjustment table. If you have a rotary cutter with a 40hp gearbox and you have it ed on a 30hp tractor you would want to set the clutch to slip at 30hp to protect the tractor as it has the lower horsepower rating of the two. If you set it to match the rotary cutters gearbox you could potentially damage the PTO drive shaft and components of the tractor, should you hit something hard enough.
