4x4 Question

[N80]

I've had that happen! I've got some deeply rutted roads and was going up one of them with the mower the other day and the back right tire was on a high spot and the left front was on a high spot with the right front and left rear dangling over a deep rut. I was kind of teetering there for a moment (the mower sort of stabilized things and there was no danger since each of the free tires where only an inch or two above the bottom of the rut). But for a moment forward motion stopped and the free wheels just spun. A quick touch of the diff lock got things going again.

If there are not any 4 wheel drive tractors..................Why did this thread run for 22 pages?

I believe the proper named is Mechanical Front Wheel Drive.

Forgot to answer your question! It's because people like you and I come back and post

Kubota uses the terms "4WD", "Bevel Gear 4WD" or "4WD Front Axle".

John Deere uses the terms "Four-Wheel-Drive". Four-Wheel-Drive Front Axle", and "4WD".

New Holland uses the term "FWD", I'm not sure if this means four wheel drive or front wheel drive.

John Deere uses the term Mechanical Front Wheel Drive or MFWD for short.

I don't know about the rest.

You are correct. In their spec sheets they use MFWD. However, in the brochures and web site they use the terms I listed above as well for both UTs and CUTs.

The spec sheets also have a area for "4WD Dimensions" as well as "MFWD Dimensions". On the UTs and CUTS the "4WD Dimensions" is blank and I think it refers to their line of huge Ag tractors (9020) that they call "Four Wheel Drive Tractors."

I've operated several tractors that had a locking front differential as well as the standard locking rear differential. They would have to be considered 4wd. They pull really well that way, but sure won't turn worth a darn!

I've deffinately operated some larger tractors and equipment that were like that as well. In fact.. some o fthe equipment, if you locked the frontdiff, you had to lock in stabilizer bars that swung out and pinned, to prevent you from turning.. thus you could only go straight.. etc... ( i didn't really like that.. )

The real check would be say an L2500 2wd like mine and a L2500 4wd.

Actually, the 4wd L4400 has a tighter turning radius than the 2wd L4400 by nearly a foot according to specs. But, that is based on one rear wheel being locked.
