I know there are not a lot of C-62's out there, but I have 4 of them. We use them in a lot of grass seed and some wheat. The main problem I am having is premature failure of the conveyor belt that runs underneath the straw walkers. It begins to split out where the belt seal rubs on the conveyor belt as the belt turns. The is wear spot eventually breaks through and the belt starts to go to pieces. I think it is just a poor design, but I am not sure how to remedy it. I wondered if anyone else who has a C-62 has had this same trouble? Any Ideas, and no I don't want an R-series for all of our grass seed! Thanks..
