Thought I'd share my EZ Hitch experience.
I didn't want to spend a lot of money, so the EZ Hitch was appealing. Found out about it on this site and ended up buying it from Jerome on Ebay. The one I bought was the design which had round posts (2pc design). Had it just a couple of weeks and it made things easier for mounting my implements. Unfortunately this round post (2pc) design was flawed and the small hitch posts were bent using my KK tiller.
I contacted Jerome about this problem and he sent me a complete new set which do not have the round posts. I used them all fall and winter and am very pleased with them as the new ones are a much better (1pc) design. Jerome sent the new ones free including shipping, so I must admit he has kept his word on making the customers satisfaction his #1 priority.
On the old ones, I have successfully bent the small post back and weld the it back in place so now I have 2 sets of them. Anyway, the key to using this hitch is having the implement on level ground. It makes all the difference in the world.
Jerome, if you are listening, Thanks for sticking by your product & good luck.
