JD Hydo 185 Slipping

Jimjones · Jul 26, 2008

My JD 185 Hydro tranny slips.Worse when hot, almost stops.Pulls ok when cold.
Any ideas on possible problem?

Its groaning because it needs replaced! Its tired, and seeking a good place to set and relax. Ya might as well bite the bullet, and either buy a new tractor, or buy a new tranny!
A friend had me haul his JD to a place where they said they could fix the groaning. I had told him it was a rip-off, but he didn't think i knew anything, so he told them to fix it, but no new tranny! I knew it wouldn't be any better, because his yard is hilly, and steep, and his tractor was 11 years old.
So, they took his cash, and i hauled it back home for him. The fix lasted one month, and it was off to the repair shop for a new tranny!

Its time for a new tranny
Deere offers rebuilt ones that are cheaper
There are 2 styles Eaton an Sunstrand used on 185s
Way to tell them apart is Eaton has cooling fan on side an Sunstrand is on top
A tractor junk yard may be considered for a replacement tranny
Good luck Gary

This is only a quick fix,but might get you going for a while. Drain some of the transmission oil, and replace it with STP oil treatment. I've done this several times and it lasted for a while.

I've been successful in buying some time for worn out hydros such as yours sounds to be by draining and refilling with a heavier weight oil. I think a multi-vis oil may even be a good idea. It takes a bit of patients to refill one, but it can be done. Rememeber to keep everything cleaner than your dinner plate!

I don't think Multi Weight oil belongs in anything short of a car ! In order for multi Weight to become thicker than 0 wt, it must be heated, and pressurized. A higher vicosity oil may do the trick [ for awhile ] I don't understand why so many people insist on using multi weight Oil in small engines. May be OK in pressurized engines like the B+S Vanguard, but [ to me ] are death in splash lube engines. I've asked a lot of Motorcycle riders what they use, and they tell me, either the manufacturers oil or Castrol 30 WT. Most of the ' shot rods ' [ broken con rod ] engines that come here have thin oil. I personally killed a snowblower engine when I had the Brainstorm of filling it with Mobil 1. For snowblowers I use Non Detergent 20 Wt, and a PTFE additive. At the end of the season, I drain, refill with HD 30 wt, run engine a bit, than change back to my 20 Wt / PTFE mix. This flushes out dirt buildup. I use Mobil 1 in my car, with excellent results, but will * never * put it in a small engine again !
