I use Amsoil Severe Gear 75/140 in my Kubota mower. Takes about 1 qt. Buy a couple of qts to be sure that you have enough. You can save the leftover oil for the next time.
Have you figured out how to get the oil out yet? I used a small hand pump to suck the oil out…. I change it every even year.
You could measure what you get out and simply put the same amount back in.

I prefer John Deere corn head grease or "0" grease for gear boxes. It is what I have/use in ALL my gear boxes.

In my new (last year) flail mower, I used 75/140 full synthetic. It came in a "bag" with a spout that was easy to install. It took one quart. I use 75/140 because it's typically hotter here than anywhere else in world except maybe the Sahara Desert. :rolleyes: The 75W allows full lubrication for the early season cool mornings too.

Should be a drain plug on the bottom of the gearbox. If it'e leaking, the Corn head grease. If it's not, any gear oil, brand irrevelant.

Any grease vs no grease. Any grease wins. :)

Only if it's leaking. Regular grease won't liquify and will cause the bearings to fail from lack of lubrication. Corn head grease on the other hand liquifies as it warms up and provides lubrication to the bearings.

The first thing I do is drain the oil and replace it with 00 picker grease. Low enough viscosity to lube the nooks and cranny’s but stiff enough not to drip out of the seals
