I'd like to understand grease better.

Here is a good compatibility chart:

The Skinny on Grease Compatibility

You will notice the newer type of polyurea (shear stable) and lithium complex soap based are widely agreeable others. There is little, of any need, to worry about it so long as you use one or the other of these consistently. Now, you guys with that green John Deere;s best multi purpose shear stable polyurea can celebrate your good choice. If you are using your grease in high speed bearings, then there is some concern that moly is inappropriate. Moly is an extreme pressure additive that almost always listed as moly, other EP additives are typically listed on the product label as "EP" ir extreme pressure. I am now using John Deere's best multipurpose green myself. It is easy to obtain at dealer or AMAZON and reasonably priced when buying the carton of tubes.

Thank you for sharing this information !! Made me recall the time my dad was adding oil to his 1954 Chevy (and this was about 1964) and I asked him if it mattered what he put in. Know what my dad told me: "Oil is oil...." :laughing:

My last carton of grease is winding down so I have been reading grease threads lately as a refresher in case there's a better solution. As usual on TBN, one thread leads to another, and I found this one from a couple years ago regarding polyurea grease. http://www.tractorbynet.com/forums/...ing/301409-recommended-john-deere-grease.html
I think I will be changing to the JD PU grease after reading Sixdogs' research. I just wish it wasn't green.

I have been using the John Deere SD Polyurea Grease for years with great success. I use it in everything, even in the loader, one grease for everything.

Then how about BLUE! Kubota's version of the SAME modern type polyurea grease is dyed blue, the color of the dye is of no consequence. The Kubota site's description of the product is more informative than Deere's. I have no idea of the price, but I imagine it is competative.

I have had excellent results with Schaeffer grease over the years. Aluminum complex with moly. I am not worried about any compatibility issues as one grease for everything from my semi truck to my zero turn mower.

You could spend a week reading and learning about all the different types of greases.

To greatly simplify it for pins and bushings and anything else where there is metal on metal rubbing like ball joints, tie rod ends, etc a grease with moly is the best choice in my opinion. The moly bonds to the metal and protects it even if the grease is gone. It won't protect it forever but is a good safety net. This is especially important in pins and bushings like in a loader or backhoe. Moly greases are usually the black nasty greases that get on stuff and won't come off.

You don't want to put a moly grease in any type of bearing. From what I understand the moly can build up and interfere with the bearing operation.

I use two greases. Deere moly for everything but bearings and Mystic JT6 for bearings. Works for me on our dozen or so vehicles/machines. Never had a failure on anything I could attribute to the grease.

I didn't always use moly grease and originally used JT6 on everything but I noticed a huge difference when I switched to moly on our loaders. When digging all day we grease our skid steer daily. Before the switch to moly the pins would start screeching mid day and we had to grease twice a day. This is heavy use though nonstop digging and loading all day.

Grease seems like such an innocent simple thing . . yet I get the feeling even its frequency of use varies greatly from user to user. //.
Also . . though my career has strayed far away from my early training as a machinist and apprentice tool and die person . . I'm ever aware of lubrication factors in most everything we touch . . yet grease seems so overlooked by many . . or at least relegated to the "someday when I get time" perspective.

When the U.S. Army first deployed the M1 Garand rifle to the Pacific in October 1942, it was the first time in a humid area with heavy rainfall. Luckily the Army had switched to Lubriplate 130A so they continued to function.

The Army regiment was put into line with the Marines (who'd arrived in August) and were quickly attacked by the Japanese, seeking to take advantage of a "green" unit. The soldiers repulsed the attack with losses of 26 men KIA and 150 wounded. The Japanese soon reported that new units were on the island "In which every man has a machine gun." An Army platoon could sustain the same rate of fire as a Marine Corps Company using the M1903 Springfield.

And so, the tide of battle in the Pacific was turned by - grease! Lubriplate 130A is still available today, though no longer the lubricant of choice for M1's and M14's.

I'm no expert, but I use the cheap multipurpose lithium EP on everything but wheel bearings (the red high temp) and the boat/boat trailer (marine blend), and things seem to work fine. I have read about compatibility issues between the grease types, so I have never changed the practices, and haven't had any lubrication related trouble. As mentioned, I think about the applications in terms of high speed vs. high pressure vs. corrosive environment. Some of the "wrong" type is much better than none of the "right".

I noticed quite a few people say the use "Mystic JT6" and swear by it. Mystic makes at least 10 different greases with the JT6 name, including moly, multi purpose, lithium, synthetic, etc. And then they also make all those in high temp EP blends. I'm just saying this to point out that some more details are needed rather than saying "I don't believe in xyz blend, I use JT6 instead". JT6 probably makes that xyz blend too.

Just what kind of lubricant are we talking about:laughing:
