I have not posted for a while. I have a 42" hydraulic tiller on my 316. I would like to be able to reverse rotation once in a while to clear debris etc. I'm wondering if anyone has installed some mechanism to do that. I was looking on line at hydraulic directional control valves and wonder if that might be a possibility. Any information on the subject would be appreciated. A belated Merry Xmas to all. Bob Levin
