***My chipper's hydraulics are acting up again, can't seem to figure it out, slide box getting stuck open and the feed wheels are stopping when a branch hits them. I'm afraid to take it to bandit and get an arse rapping again with nothing getting fix. I'd think I'd have better luck taking it to a lawn mower repair man.***
Buddy of mines 250xp is doing the same thing I think, infeed rollers stop feeding once a branch touches them. Are you running a Bandit? And the "side rails", are those the rails the rollers are guided by on the outsides of the machine. Its driving him nuts. The down pressure assist is working,( opening the rollers) but they won't work on their own once closed.
