Eatons are top notch. You really need to ID the trans. 11s were multigrade- 10W30 or 40. The 10's were type f ATF.

WHen I looked up H14- it showed 10W40 for what it's worth.

Ok then. I was hoping the hydro was a good one. I do a lot of tilling, and snowblowing with them. I think I saw ATF F type somewhere too! Thank you guys, vary helpful! OHHH! I almost forgot! Anybody know how well those hydro lifts work for attatchments? I didnt know if it would pick up a heavy tiller or snowblower, Thanks! Mike.

I would think it will do real fine.

Not sure which Bolens you have.

I've got mid-80's H14-XL and my manual is dated 1990. Manual says SAE 20 or SAE 20-20W Type SC or higher. If subject to heavy use manual recommends SAE 30 in hot weather.

Charge pump also powers accessories. I only have mower, and is more than sufficient for deck lift.

Ok thanks a lot guys. I sure do like th help!

I have a nice old Bolens H14. I successfully use multi-purpose tractor fluid for its combined transmission/hydrostatic pump setup. There is no definitive answer of what to use exactly. Eaton itself suggests a high-quality transmission fluid or multi-purpose fluid, the hydraulics do better with lower viscosity fluid, like 10 or 20wt max, but as you have read, other people have used multiweight just fine. If you are in cold areas, the hydraulics might become fussy with the heavier multiweight.

My H14 manages heavy attachments just fine - that is what it was designed for. I have a tiller and a front snowcaster, and it handles them a treat. The H14's Eaton hydrostatic can also manage a front loader bucket very nicely. Those Eatons are sweet, on any brand of tractor

Change the filter - they work better with good maintenance [grin]. Your H14 may have that goofy in-line filter like mine did, which are no longer made. I had to fashion a new setup to accept a screw-on filter.

When you say multipurpous, what do you mean? Multi purpore tranny fluid? Hydrolic fluid? Does it hae a brand name?
Thanks soo vary much! Great advise!

What you are seeing is how specs have really changed over the years. Straights were replaced by multi-grades. I've seen where people go to full synthetic to do the best they can do in their minds. There are generic tractor hydraulic oils that fit the bill of a multi purpose oil. I personally don't know of better than JD Hygard.

When you say multipurpous, what do you mean?

go to the Tractor Supply Company site and search for Traveller Universal Tractor Trans/Hydraulic Fluid
and their description should help. Or just search the web for Universal Tractor Fluid.

There are other brands of combined tranmission and hydraulic fluid, all are a compromise between tranny and hydraulic fluid with lots of additives, and it is kept inexpensive because farmers have to watch their costs. Even the little H14 uses two gallons. I got 5 gallons for $30 (prices are $30-$50, depending on brand and store).

Tomplum recommends Hy-gard, I have no strong opinion. I know others have run tranny fluid and universal fluid for years without problems. Synthetic is usually better and always much more expensive. I would not fill it with expensive synthetic fluid until I fixed all seals and leaks.
