mattd860 161 #1 Posted January 11, 2011 My father just picked up a nice mid 70s Case 444 Hydro tractor with snow cab, snow plow, mower deck, and snow thrower. I think there may be a problem with the Hydro though. When the tractor is moving forward or reverse, if I move the "drive lever" to the "neutral" position too quickly, the rear wheels will completely lock up causing the tractor to skid to a stop. Is that normal? It's very touchy meaning that even if the lever is slowly put into "neutral" the wheels will still skid since the tractor is kinda large and has a lot of momentum when moving. PS. I know there is technically no neutral on a hydro rear end but you all know what I'm talking about :banghead: Share this post Link to post Share on other sites

I know there is technically no neutral on a hydro rear end but you all know what I'm talking about The Case & Ingersol tractors are not hydrostatic, they are hydraulic drive. Sounds like a problem with the direction control linkage at the drive control valve? Or could be one side of the control valve itself is sticking. They use a hydraulic system like a front end loader. Only instead of lift cylinders your valve controls the speed of the wheel motor. Share this post Link to post Share on other sites
stevebo-(Moderator) 8,059 #5 Posted January 12, 2011 Matt, That is a great machine-a real workhorse. BEFORE you try driving it down any hills you may want to find out if it has a "holding valve". If it does not, that machine ill free wheel and that is NOT fun. Share this post Link to post Share on other sites
