oldiron 0 #1 Posted January 12, 2009 Hi folks. First time here. C160 automatic After many years of dependable service, one of the two wheel horses let me down. after 5 inches of snow last night I started the horse with the snowblower attached and found the hydro lift will not operate. It does nothing at all. The tractor will go front and back OK. Is there anyone that knows what the culprit is? Thanks in advance Share this post Link to post Share on other sites
kpinnc 10,733 #2 Posted January 12, 2009 If it's not leaking, it could simply be an O-ring failure in the cylinder. that would allow fluid to bypass right back into the return line. Otherwise, there is a fairly thorough but simple procedure in the Sundstrand (Auto Transmission) manual for troubleshooting. Good luck! Kevin Share this post Link to post Share on other sites
refracman 166 #3 Posted January 12, 2009 Hers a link to the trans manual https://homeownersolutions.toro.com/portal/...nualsResultPage Like Kevin stated it could be the cylinder, or the trans, Make sure it full of fluid too Share this post Link to post Share on other sites
.5racer 14 #4 Posted January 12, 2009 Could it be possible it is hooked up wrong or come aprt at the lift ? possibly unhooked from vibration. Have had cotter pins come out and links fall off on me before .Even have forgot toput the da#m pin in and come apart later during plowing. Share this post Link to post Share on other sites

Buzz 502 #6 Posted January 12, 2009 Here's a direct link to the manual if you need it. I like the idea of starting with the simple stuff and looking to see if the linkages somehow came unhooked. Good luck. https://lookup3.toro.com/request/filechek.c...=Toro&PubType=9 Share this post Link to post Share on other sites
oldiron 0 #7 Posted March 1, 2009 Well I was looking for the problem and thought it might be in the implement valve so I gently tapped the housing with a hammer and the lift started working again. I don't know if there is dirt or moisture in the oil. The weather was below freezing for a few weeks during the time the lift was dead but it is now warmer so moisture in the oil is suspected. I will do a full oil and filter change and hope the problem does not return. Thanks for the sugestions. Share this post Link to post Share on other sites
Sparky-(Admin) 19,550 #8 Posted March 1, 2009 Gotta love a story with a happy ending. Glad to hear you got it working and I'm sure someone on here will be "gently tapping" their valve. Good info , I would have never suspected that. Mike........ Share this post Link to post Share on other sites
Operator 7 #9 Posted March 1, 2009 Back in my commercial plowing days we would add "Heet" to our out front plow pumps because of moisture freezing them. It worked, but I wouldn't suggest that for hydros on tractors. Randy Share this post Link to post Share on other sites
