Hey Wen & the rest of you restless tractor fanatics of varying colors,
Will you allow me a late comment on what you said about part-time 4wd, etc? Full-time 4WD may not be as rare as you think. Over many years I have gained some experience on the subject with many wheels bought and maintained at great expense. Sigh.
Starting completely off topic, we have a 911 (Carrara 4) & a MB wagon (4-matic), both purchased 10 years ago. Each has what is referred to as ALL-WHEEL drive. It stays active ALL the time, no option, and the % split between the front and rear wheel pairs is controlled by a computer reacting to slippage that the ABS detects. Sometimes that is referred to as full time 4WD, but not by purists.
I take one point back, we can lock the wagon's 4-matic in for low speeds only, if conditions are bad.
Most fun I had up to the time I did it: dropping the clutch on the Porsche in our gravel parking lot and marveling at the way it clawed its way forward barely spinning ANY wheel! Scared my wife. ;-).
The Chevy 2500 (3/4 ton, Silverado, 2000 model) has 4WD with what Chev/GMC calls its ACTIVE transfer case option. Means I can leave it in 4WD high all the time since like the aforementioned Euros, it comes in on demand, only. I have however noted a shuddering on turns on dry hard pavement, which I intend to ask the dealer about, but I suspect it is an imperfection in the design. The Benz has that too, but its guilt (with 177K miles) is established--it needs a new transfer case, at many Deutche Marks.
And now for the topic the new guy has been waiting for--the damn tractor...
Ole New Blue, my TN90F, has "traction management". Best I can describe it, it is like the truck--the Italian Delight flicks on 4WD when the rears slip. The option is there to lock it in or out of 4WD, too, but why? I can also electronically lock the differential. Under TM, 4WD also comes in when I apply the brakes and on certain other actions. It cuts OUT when you turn sharply to avoid crab-scuffing or whatever you call it. Works.
Don't the Boomers have this option, also? Sorry to be so wind-dee, but Wen got me thinking, and the smell of wood burning was overpowering the Mac, so I figured to put out the fire with words that will hopefully have traction....
Some "friend" once called me "Mr Toad". Not sure if he was referring to the wind in my willows or the (many) vends for my wheels....
BTW, 2 more stinkweeds bit the dust Saturday.

PS: There is actually a www site devoted to explaining the technical differences between the various all/4 WD systems, I just cannot find it at the moment. Complex? You got that right!
