M7040su?

[Riverhawk]

Hello everyone.

I am shopping for an M series tractor in the 60hp + range. I found a clean 2014 7040SU. I am not sure what the SU means? I saw the article here saying it means "special utility"... but what does that mean? Tractordata.com says "economy model"... The seller is saying this is one of the last "non-emission" tractors. Is that true if it a 2014?

What does the economy part mean?

Is the SU a good thing or is it unnecessary complexity?

I want the simplest, yet most recent motor/tractor possible under 1000hrs.

I currently use my father-in-laws 2013 6040D, and love it.

Riverhawk, welcome to the forum. The SU at the end of the model number usually indicates it is a special unit. As you know it's a "simplified" model, meaning no bells or whistles. And the important part is it's two wheel drive.

The "number" with SUD was 4x4. The "D" is the key letter, indicating four wheel drive.

A M7040SU just won't have all the fancy / finer controls and functions.

This info some else posted previously might be of some help.
Looks like a 2 wheel drive model

Thank you for the tips guys.

I have learned more about the SUD designation.

I am currently considering buying a 2014 7040SUD (4x4)... but I am nervous about the transmission being "partially synchronized" with only 3rd and 4th gears synchro'ed in high range.

The other "economy features" I don't think I mind.

Maybe I am wrong but suspect the synchro's would exist in both ranges not just hi.

Regardless and even with full synchro's , you will not find the shifting of the transmission like shifting a manual transmission car.

I often just start in the gear I want because, by the time I complete the shift, the tractor has slowed so much it is like starting all over anyway.

Unless you are hauling heavy loads at speed in hilly terrain it should not be an issue.

Thanks Dave, thats helpful. I am beginning to realize why the H3 and H4 would be synchro'd because it makes more sense to start in those gears and shift up and down in them, and not down to H1 and H2. Having Low range synchro'd makes sense since it likely you will have shift a lot in those gears... like when plowing or pulling a large disc harrow.

I am so used to clutching and shifting other vehicles, I run through the tractors gears more than I need/should.

What year 7040 do you have?
