Good, if you can figure out what size pin to useI've had this for about 10 years, came back to the site to see if I could figure out what size pin to use to pin it to the tractor PTO. Of course it doesn't say. this is the 2nd time in 10 years I've sheared the pin, last time I just bought an assortment of various sizes and found one that fit. I use this on a Farmall M with a 6' bush hog and a 6' finish mower.

Not bad, not goodI've had two. First one broke the pin and it got smashed when it got pulled off the tractor side of the pto. I'm on number two and it keeps breaking pins. I'm sure it's the inferior pins, but I wish this said what size it needs so I knew if I had the right ones. Just broke another about 10 mins ago and the pto shaft hit me in the side. Had a good one on this tractor for 20+ years, wish I had another one of them now.

Confusing informationHeader description says "MALE SPLINE 1-1/8 IN. X 6" but details say "1-3/8 x 6." It can't be both. The header needs to be fixed. This unit has 1-3/8" male and won't work if you're attaching to an old Dearborn or Ford implement with 1-1/8" female spline.

Make sure you get the pin with the unit!!There is a pin that will need to accompany the unit. The pin is inserted through the grease zerts holes. the pin prevents the unit from falling off the tractor PTO shaft. Mine did not come with a pin! Therefore I will have to make a return trip to the store to locate a pin!
