I have a Ford model 951 brush hog (5ft). I am wanting to change the gear lubricant. The manual calls for any of the following: Sunoco 850AEP, Gulf Mining HD Lube, Mobile EP023 or NLGI grade 000 EP grease. I aven't really found anything other than large drums or pails. I really only need a few quarts. I would appreciate anyone's input as to what an equivalent would be?

You can get "corn head grease" at local John Deere dealer or by the case at shoup.
It is oo or ooo.

I've used Napa Premium 80w-90 gear oil for decades in my '82 Covington Cutter and 2004 Land Pride rotary cutters and never had a problem with the gear box in either mower. You can get it in quart bottles. I think that Tractor Supply has their version but you have to buy it in a 6-pack.

I think 80-w-90 is too thin for my gearbox.

Is your gearbox leaking?

Right now,no. I have a feeling it might after puting 80w-90 in it which is much thinner than what is in the gearbox now.

What weight gear oil is in there now?

Whatever was put in there originally. Manual says NLGI HD 000 grease. That's thicker but I cannot find it.

Then I would take Dean's suggestion to get the John Deere Corn Head grease. Many Ford N tractor owners have used that in leaky steering gear boxes with success.

Thanks, that is what I will get.
