I have been browsing the past posts and found this post ( http://www.tractorbynet.com/forums/oil-fuel-lubricants/94858-grease-please-educate-me.html ) very educational - thanks for all your patience and knowledge.. I was CLUELESS that all greases are NOT created equal.. It has been an eye opening experience so far..

As a followup I have a couple more questions that werent answered in the previous post:

My JD manual calls for the "Polyurea" grease in the loader - Do you know which polyurea it is OR how compatable it is with other greases?

How compatible are synthetic greases - What TSC did not list what base it used...

TSC has 'green grease' www.greengrease.net - any comments on it? It is a 'mixed complex" grease - What does that mean, and how compatible it is with other greases. I looked at your compatibility chart, but wasnt sure which 'mixed complex' was.

Here is the green grease specs

Thickener ............................................................Mixed Complex
NLGI .........................................................................................2
Unworked Penetration 25°C (77°F) D217...................... 280 / 310
Worked Penetration 25°C (77°F) D217 ......................... 285 / 315
Dropping Point 290°C (554°F) D566.................................. 554°F
Water Washout Test D1264.................................................Pass
Rust Test D1743 ............................................................Pass #1
Corrosion Test D130............................................................Pass
Timken OK Load lbs D2509.....................................................80
Four Ball EP Test Weld Load kg D2956........................... 800kg+
Four Ball Wear Scar mm D2266 ......................................0.0 mm

Hmm, mixed complex. Sounds like they don't want to divulge what the thickner type is for their grease. The spec's look prety good but I'm a little leary about it since they don't tell you what the thickner type is. Can't say I have ever run across the Green Grease before so I don't have any first hand experience with it.

I'm not a big fan of Poly Urea thickened greases due to it's poor compatibility with other grease types. For general tractor use and chassis lubrication I like either Calcium 12-Hydroxy Sterate or Lithium Complex greases. They are the two most compatible thickener types that are readily available with the Lithium being the most common and easy to find.

As far as synthetic, the only thing that is really truely synthetic in them is the base oil (and sometimes a couple of the additives in them), and even that is often a blend of conventional and synthetic base oils. Unless your operating at the North Pole or on the surface of Mercury you probably really don't need a synthetic grease.

If you have either a BH or FEL I would suggest a Moly fortified grease. In this type of low movement high load applications the Moly can really help to reduce frictional wear in boundry lubrication situations. One reason Caterpillar spec's a minimum 3% Moly fortified grease in their equipment.

thanks for the advise.. I sent green grease a message asking for the base type and compatibility.. Green Grease was at TSC for about $8 a tube - Not that higher cost makes it better, but that is what caught my eye...

Looking at walmart/tsc/autozone (my best available sources) - its hard to find a good grease because most dont list the specs (specifically the timken rating).

thanks

WOW.. someone at Green Grease is working this morning.. I just got a reply back from them..

DieselPower - Based on what the reply - what is your take on its compatibility?

===============
Green Grease reply:

Hi Brian,

Green Grease will work great in your mower as we are the only grease in
the world that is fertilizer resistant. Tractor Supply had us put that fact
right on the front of the tube. Our mixed complex base means that is
compatible with all lithium complex greases - just pump it in right over the top of what you are using now. The base is mixed because we put synthetic polymers in Green Grease so it sticks to metal and will not wash out. Hope this answers your question. You can buy Green Grease at all Advance Auto Parts and Tractor Supply COmpany stores or on-line at our secure web site Green Grease Home Page.

What is your opinion of Chevron Ultra Duty 2 EP ? I use it on my truck and Kubota L4400 and loader. ?

DieselPower · Jul 5, 2007

They still completly dodged the question by not telling you what the thickner type is. That's great that it's compatible with all lithium complex greases but what about the other types. The only grease in the world that is fertilizer resistant. Oky-Doky if they say so. Most high quality greases perform well in fertilizer spreader applications.

jsborn - I don't have the Chevron Ultra Duty 2 EP spec sheet at hand so I'm not sure how it rates.

DieselPower - here is the reply I got back from Green Grease - Would you recommend using it based on the specs with this additional information?

Green grease reply =========
It is a lithium complex but we add state of the art synthetic polymers
so this is why we call it a mixed complex. We also add Extreme Pressure
agents, Rust and Corrosion inhibitors, anti-wear additives, and lots of other
goodies to make it the absolute grease money can buy. We have been in the grease business since 1977 and our bread and butter business is industrial, mining, marine, construction and farming applications around the world. We sell to Fortune 500 companies like steel mills with $20 million pieces of capital equipment that is flooded with cooling water 24hrs a day and they have found Green Grease is the only product that works. Try a tube and you be a loyal customer for years to come.

thanks for the education DieselPower

They seem quite proud of their product! At $8/tube I guess they should be. Sounds over the top to me. I can't see how one tube of use would tell you anything about the grease unless it was so terrible that your equipment failed after using only one tube. I think it would take 1000's of hours use to tell the difference between a good grease and a wonderful grease.

DP has posted his favorite greases on several other threads. I have nowhere near the expertise he does. My only 2 cents is that John Deere sells several kinds of grease that, at the worst, should be perfectly adequate for anything that 99% of us are doing, and which usually run $2.30 a tube at my local dealer. Their options include three lithium-complex based greases, one of which is moly fortified (and I would recommend either that one, which is gray, or the non-moly HD grease which is tan). I'm not saying that JD grease is necessarily the best you would ever find, but I think it would be much more than adequate and is easy to find and inexpensive.
