It was so much fun I installed it 3 times! The first time I just mounted it to the tractor and had to drop it again to put the connection for manual pushing, the second time I had to drop it so I could put the arm for forward and reverse because I couldn't put the cotter pin in place under the fan blades. After that, I spent two days trying to figure out why the forward and reverse control would not move. After I talked with Darrick in support chat (who tried his very best to help, but had no access to instructions or there are none in existence), I came out to the garage and loosened the bolt on the transaxel where forward reverse connects and it solved the problem. I thought, the very first moment when I discovered forward and reverse would not move about adjusting that bolt but talked myself out of it because I didn't think that it would come delivered out of adjustment. So I just kept trying to figure out what I had done wrong. With that being said, I learned a lot and could do it again in an hour if I ever have to do it again. Let's hope not!
