kamsdad97 0 #1 Posted September 28, 2009 I own a 1979 C-141 auto with hydro lift. When I lift my mower deck up( or snow blade, or snow thrower) it will slowly fall back down. The other day when i first started it I lifted the deck up and it stayed up. I could eaven stand on it and it would'nt fall but after moving it up and down a few times it started falling down on its own again. Is this because the lift cylinder is not holding or maybe there is some other problem I should adress first? One hose does seem to leak a little but only a few small drops after an hour of use like plowing snow. Thanks in advance Share this post Link to post Share on other sites

tgranthamfd 29 #3 Posted September 29, 2009 I know absolutly nothing about hydros, but it sounds like a leak or fluid bypassing a seal or vale sticking internally. Like I said, only a guess. Good luck. Someone will see it and have the correct answer for ya. Share this post Link to post Share on other sites
