Which oil weight is best for a Bush hog

 

[Sawyer Rob]

80- 90 gear oil is used mostly, any decent brand will be just fine.

If the output shaft is leaking you can also use corn head grease which is basically a #0 or #00 semi-fluid grease.

Running 80-90 gear oil Oreilly store brand in mine. Zero problems , changed maybe every 5 years with 50hrs/yr.

I think you'll need to search for Spindle Grease or Flowable Grease, but 2nd this is the seals are old.

I run 80w-90 gear oil in mine. It's got all the right additives for that type of friction & seals.

That's what I run in the Ford 917L flail mower. Even 120 weight gear oil runs out, the seals are so bad.

Corn head, Spindle, 00 grease is known by several names and is fast becoming the lubricant of choice for gear boxes (especially old ones) since it will flow and keep everything lubricated. But most importantly will not leak as readily as regular gear oil. I use it in all my gear boxes old and new.

What I am hearing is there are two options. Pack it with grease if the seals are bad; use gear oil if the seals are good. Downsides are oil leaks and greases cavitate. Does anyone use a mixture?
