Synthetic 90w in mower deck gear box

Tims A · Apr 24, 2013

Seeking wisdom of using Synthetic 90w in mower deck gear box. I mow about 4.5 acres so when I mow this gets some work. With so little oil in there I thought Syn. might help.
Thanks,
Tim

I have seen great results using Mobil 1 75-90 synthetic gear lube in gear boxes that tend to run hot or are of limited durability in a given application.(White 8800 cylinder gear box)

Also, the operators manual says to use only Mobil 1 75-90 synthetic gear lube in the gear boxes on my Shelbourne Reynolds stripper header.

I don't use anything but synthetic, engine oil, gear oil and grease.

Tim use of Synthetic 90w in mower gear boxes(that we service) cut box failure more than 80 % . At our dealership that is all we encourage our customers to use.

All other factors identical. A thicker oil will run hotter than a thinner oil.
Try the thinnest extreme pressure trans-hydraulic oil. A synthetic version of Hy-Gard or the stuff that IH uses should work.

The stuff that IH uses is called Hytran, much better than the stuff JD uses.
