This hitch is being used on a Jonh Deere 420. The hitch is very nicely made and made of a good thick steel. The only problem I had, was that one of the predrilled holes on the bottom square pads mounted to the under part of the axle was off by about 1/2â€. After I redrilled the hole it all line up.
When I received the hitch, I noticed that the mounting plates were on the wrong arms, according to your picture. Otherwise everything was okay. I'll soon use it
