    Hey guys, we recently purchased a kubota kx121-3 brand new. it has 35 hours on it now, and since we bought it, i was just using the generic tractor supply grease i had laying around. after finishing off my second tube, i realized im gonna need more.

    i go online to buy a case, it turns out there are a ton of varieties of grease.

    seems like a lot of guys like schaeffer's #2 238 grease. is this ok for our kubota? what is best for the pins, hinges, etc on the machine? what is the difference between #1,#2,#3 greases?

    We use Lucas Xtra heavy duty grease for everything. You can buy it at Advance for $4.99 or so.

    Looks like it's a high pressure/high speed moly which is what your manual probably recommends. There should be a page or two in there has graphics showing what lubes to use in certain temperature ranges. The grades are sorta like oil weights. Lower numbers have better low temp performance. I've never used anything but #2 greases.

    I like hi-temp grease. It gets a little messy no matter what grease you use but the high temp grease "seems" to hold up a little better in the summer. There are so many grease fittings that I'd rather not pay $4.99 tube but I often end up paying that.
    I've used the Lucas and I like it but generally use the red, high-temp grease in both my skids, mulcher, and mini ex

    I'm in the same boat.

    I bought five cases of the Tractor Supply grease on a close out sale at $8 a case. I know its not the best grease out there so I've been greasing my ctl at lunch too just to make sure things are lubed.

    I used a rental once that had some kind of gummy light blue grease in the fittings that stuck around all day pretty well. Anyone know what that might be?

    Schaeffer's. #238 That's all I use. And I use a lot of it. It works well.

    Some grease is better than no grease at least!

    Nothing bad about moly, just don't put it in roller bearings, it can build up in races and cause problems. Anything else is better with moly.
