mobil 1 15w50 in hydro

[wesk]

Good Morning fellow tractor nuts;
Changed transmission fluid this morning with cub filter and mobil 1 15w50.
Tractor runs quiet and strong. Wanted synthetic for winter use.

Good deal wesk. I assume this is on your late model 2550 where Cub Cadet Drive System Fluid Plus is specd? I too bucked the system ~4yrs ago and swapped out to Shell Rotella-T 15w40 for the trans on my 2544. I dunno that I would have gone to a 50wt variant for winter use, but it should be fine for you.

I have to jump in here, I have been using Mobil 1 for several years in my motorcycles (Gold wings), and have not had any problems year round. Here in New England it gets kind of brisk during the winter, and when I was a working stiff I rode year round except when there was ice or snow on the road. I did have to question my sanity a couple of times while suiting up when the temp was hoovering around 18 deg. The 15-50 did not give a problem. I started using it in a 1200CC Kawasaki Voyager, and the first thing I noticed is that I could shift it without hearing the gears clash. I used to pull a camper with the wings, and never had a problem. I used the 15-50 in my old Rears, and Throwback (Sears) riding lawn mower, however I did not use that in the winter. I will be using it in my CC in another week or 2 as I almost have 50 hours on it........

Right, but your average TuffTorq holds 2-4qts where the Hydrogear driven rears on our Cubs hold 6qts. I've never known overheating to be an issue with them, where (although a great trans) TuffTorqs will overheat given their small capacity. I'd go heavy and synthetic on a TT fo sho.
