WainRoy
I bought my JD 310c with the WainRoy backhoe bucket already on it, it's great for easy on easy off if you needed to drop the weight on the back for certain jobs, I don't have any other buckets but I'm sure its a great system to have if you are always swapping out buckets... but the thing that happen over a few thousand hours is right where the bucket hinges on when setting it into place has worn down on the ends, and now the bucket moves side to side real sloppy like... I don't know if its my fault because I should have kept it greased? but I think it can't be an area to have kept grease on it, because it's not like its a moving part...
I have a post some where showing pictures of it when I was talking about the teeth on it. if anybody wants to see pics here let me know....
I've never seen any other fast connect buckets to compare, but if I was going to get more WainRoy product, first I'd look into why my WainRoy hoe bucket now has a lot of side to side slop on it and if its my fault...
