Case 1840 Skid loader

Has anyone ever run across this problem: When it gets much below 45 degrees, our Case 1840 skid loader one hydrostatic drive side won"t drive until the machine warms up a few minutes. It"s either go or no go - it doesn"t slip at all once it decides to go (you can stall it when digging into a pile). Once it is warmed up, you can use it all day with no problems, and if it"s above 50 it works even when cold.

Any ideas? Thanks!
 
I relize 45 isnt that cold that being said.. I will usually let mine warm up a couple minutes even at that temp. Winter warm up times is longer.. mine is kept inside shed most of the time also with a block heater BUT that doesnt warm up the hydrolics.
 
It seems to be stumping the best so far. We've had it since new for 10,000 hours, and it just started acting up towards the end of last spring on cold mornings. Then it worked all summer. Now it's back to acting up until warmed up. The fact that one side works when cold seems to be odd, and that once the "cold effected" side gets warmed up, it works perfectly (no weakness at all).

Thanks for the ideas so far.
 

My Ford NAA was like that, no hydralics untill warmed up, then good as gold.
Replaced the seals and a bearing in the pump. No more sucking air on a cold day.
Might be something like that.
 
Just had same problem. under the floorboard there are two park pins the go into chain case(one on each side)they are controlled by cables hooked to safety levers that fold down in front of operator. Ours had a build up of water/dirt around the pins and froze warmed it up in the shop cleaned out dirt problem solved.
