I'VE HAD IT!!! Today i called DLL who i have the tractor leased through to get them involved. This ReGen BS started in September of 2015 when the tractor was 14 months old and 192 hours. I have 554 hours on it now. Area rep won't return calls, Dealer don't want to see it in his yard again and of course no satisfaction from corporate. If the leasing co. can't help i either dump it on a Mahindra and take it in the shorts or find a mechanical pump and pull all the emissions bull$hit off. OH, New issue too boot, Rough gear noise in midrange. Quiet in low or high......
