Hello, just bought my first lawn tractor (john deere 185 hydro) ran across this site while reserching this mower which helped convince me to buy this mower. I have looked at the other post regarding the j.d. 185 and found out I have the eaton trans. and maybe the peerless diff. My question is how in the world do you fill the diff.? I cant find a fill hole anywhere. Please Help

Not sure, but maybe it's like some of the lower end trannys of today where you drain/fill through a vent cap located on the top.

I'll let Herd help you, but the Hydro is filled from the tall black tube behind the seat on the 175 Hydro !! ?? If that helps

Thanks for all the help so far. I have already changed the trans. fluid it deffinitly fills under the seat and has a vent drain as well. The differetal or transaxle is a different unit and has a square headed drain plug on the bottom right of housing I pulled it out when changing all the fluids (thought it was the trans. drain at first) but nothing came out which concerned me. John Deere dealer told me 30w oil would work and said the fill was on top , but cant find it

Look for another square head plug further up on the differential, I think its on the rear of the housing IIRC. That is the fill/level hole. I think you can use 10W-30 in the transmission but not sure that's what the differential uses.

Ditto on the comment by H.O.D. Mine has another square head plug above the drain plug. The last time I changed it, I used a small funnel, some clear plastic tubing ran through the tranny tube opening, two beers, six Marlboros, and about 1/16 of my remaining patience. The Peerless Differential uses 90wt. The Kanzaki dif uses 10w30.

Not to hijack but I was under the impression that the trans on the 185 was not serviceable. The manual that I HAD said not to change it?? Is that not the case??

I guess it couldn't hurt me to change the diff fluid. 30 weight though? No 80/90???

Great to hear this, amazing what a little work and some fluid changing will do :fing32:.

Many dealers will tell you not to change it although its not clear if there's any other reason than they can be a beach to purge. The dealer was pretty emphatic about recommending I not change the trans fluid on the 175 and my service manual also says not to change it (but I think recommends a service interval elsewhere). The differential fluid may be 10W-30 or 85W-140 depending on the transaxlw typas Cat385B posted. As to how to check I don't know, maybe look for tags on the transaxle or maybe someone knows a date or S/N cutoff.

So what, is it like changing power steering fluid....have to let it run and all the bubbles come out over time??

Basschaser, how did the fluid change operation go?? Simple drain and replace?? How did the fluid look?
