Got a dual 250 loader on a H with a pto pump. the loader doesn"t like to work when it"s below 10 degrees. It takes about 20min for the hydraulics to warm up. Is there a tank heater I could plumb into the hydraulic system? Or should I switch to a different hydraulic oil?

Get away from the petroleum-based oils in cold weather. They thicken significantly. Even the Hy Trans is only rated down to -20 (useless at -10).
My suggestion to you is to switch to a "pure" synthetic like Amsoil (Group 4 synthetic), as opposed to a para-synthetic (Group 3 synthetic). The group 3's are still petroleum based. Try the Amsoil ATH Synthetic tractor/transmission oil. This stuff is liquid down to -47F, not to mention that its got a great additive package for long life.

Red,

Mowr has it. At the left upright, take the hose off at the bottom. You should find a screen in there. Probably has never been cleand.

Drain all the oil out of 'er and replace with any good hydraulic oil. If the PTO pump is any good at all, it should then work fine down to about 30 below.

The loader works, it just makes that old H work really hard to strecth those loader arms, when it's really cold. I checked for a screen this past summer when I changed the supply hose to the pto pump. No luck.

Just thought I could add a tank heater of some sort to make things easier on my dad when he's using the tractor to clear the driveway. I'm going to try to add some powersteering and steps on it for xmas. That should make pushing snow more fun.

I"m sure it"s got fresh oil, most of it leaked out when the main supply hose got torn off.... good thing we were on the gravel drive. What a mess. I just replaced it with your standard hydraulic oil from TSC. I suppose I could go try the hytran stuff but I think I would have leaks every where if I used it.

Could the screen or filter be getting clogged causing the oil to need to warm up enough to flow through the restricted area faster?

dont put gasoline in,put some diesel fuel in instead we used to do this in our 930 case.. it doesnt take much but you will have to use your judgment according to the total volume and this will have to be drained when the weather gets warmer..

You should be able to get a lighter weight oil for winter. As far as a heater goes, magnetic might be enough but from what I've read, a water heater used at half it's voltage is good for hydraulic oil. ie/ 220 volt hooked up on 110. They do make oil heaters though. My skid steer has one. Kind of like a block heater. Dave

Look for an oil with a low Pour point

pour a 1/2 gallon of gas in the loader tank.

If the reservoir is steel, use a magnetic heater. But first I'd find the right oil, according to ambient temp.

The tank is built into the loader frame- I wasn't sure if a magnetic heater would work well. The tractor already has a external tank heater for the coolant. Suppose I could get some more heater hose and wrap it around the hydraulic tank and plumb it into the system...

I'll try different oil and a magnetic heater first...

You might try an oil-to-water oil cooler plumbed into the system, the only problem might be circulation. They do have hydraulic oil heaters they use in the construction industry for cranes, excavators, etc. You might try this site; Link
