I received them yesterday, gave them a quick try, and it's not looking good. As far as fit, they were tight until I ground down a couple of small weld tits on the tractor that were sticking up higher than the rest of the lift arms. They fit really sloppy. Then I took them off and inserted the schedule 80 1.5"? 3/8" of pvc pipe like it says in the instructions. This would be the piece of PVC they DON'T don't show on the ebay ad! Then they don't swivel like the ball would.
Now to actually try them, well my lift arms don't go down as far as I'd like to use these so I had to put another brick under the tounge of the york rake for them to line up. Still, I should have known I'd need a "stabilizer bar" across to hold the arms apart, so they still needed me to go help them into place.
Since they sit taller, I drove the rear wheels onto bricks and the rake still went low enough. It was late so before I take it off to mow the lawn today, I'll try to lower the rake at more of a tractor angle (down in front and up in the rear.
After I'm finished typing this, I'm going to send a note to the seller asking if I can return them even though they are already all scratched up. He takes returns but I don't know if he returns his shipping charge of $20.
I'd like to see pics of the various stabilizer bars any of you use to hold the arms apart. Although it sounds like these are two small piles of manure, a bar like that could make these worthwhile if the rest works out.
