frozen hydraulics!

Ya may have to undo some fittings. Refill it keep it tarp covered out of the rain and it will probably be fine. Any milky looking oil has water in it. I found the hard way yellow bottle gas antifreeze may stop a carb freeze up but to remove water you NEED red and a hypodermic sucker into the tank to get the water first if its bad. The yellow will NOT make the water go away. Both are available at Walmart, probably Tractor Supply, and AutoZone. I prefer the heat brand and been through this a million times running generators 24 hrs in the rain.

Also If you have air in the system and it is low it may do the same thing till the tractor runs a while and foams up enough pressure for everything to work. Give everything a check levels etc and start there. If oil is creamy you know you got water. Depending on if your on the rear pump or a front pump a rear pump can be sluggish when only slightly low. Like a quart or 2 On my tractor 311 B the front oil fill on the rockshaft is the back lift pump and the pipe plug on the front of the triple range shifter cover has the dip stick to check it.. The front pump runs with hydraulic tank of the loader. My 3 point lift (back pump) was slow as I lost a qt or 2 from the auxiliary hydraulic fitting leaking. Its usually uses 10w40 this time of year 10w-30 even 5-20 or 10-20 when its this cold, or if is just low add something thin like 10 wt toll it warms up. I try to just change all oils in spring or at least drain strain and refill clean. Hope this helps Cheers Rob Sandera
