This is the coolest M I have ever seen. This picture was hanging on the wall at the Farmall Land Museum in Avoca IA.
Very nice museum and very nice collection.
I want to buil one of these M's

I think I'll check into modifying a truck axle to do this as they would be easier to get.

I have that same picture.M is 1939,axle was made by 'Elwood',used a chain drive mechanisim from the belt pulley gears to drive the thing.'Elwood' made axles to fit many tractors into the '60s.If you were to build one,that would be waycool!good luck
 
That's a very cool M, thanks for sharing. I do have one question, though. Wouldn't the MFWD bog the tractor down if, say, stuck in the mud? I wouldn't think an M engine would have enough umph to keep all those tires going & pull a good size load through. I have been wrong before. Once. ;v)
 
So you're saying that a brand new, compact tractor with 30 horsepower and mfwd does not have enough power to utilize the mfwd?

The whole concept of mfwd is to get more work done with less horsepower.
 
Its all about percent slip and efficiency. If the rears slip under load on a 2 wheel drive tractor the answer was always add ballast/weight. More weight equaled more power necessary to move it. The front wheel assist is an efficient way to reduce slip without adding as much extra weight resulting in increased efficiency "more work with less power"
 
Ah, that does make sense. Added tractve effort through the same amount of power. I like that bit of info quite a bit. So, I should be able to put a live front axle on a Farmall Cub & not lose any power, yes?
 
Delta,

You can't use the belt pulley drive gear. Power has to come from the main shaft, ring gear, bull pinion shafts, bull gears, or axles. Elwood obtained their power from the 4th/5th slider when it was not engaged. I have an early Elwood. I don't think that gear is functional in 4 wheel drive. It is slid back and won't make contact with the Elwood gear. R, 1, 2, 3, and 5 are OK. TA should be alright but someone welded up the planetary gears on my 660 so I can't test it. My Elwood will fit all the M, W-6, 400, 450, 560 with minor modifications.

Here is one shot of the transfer case. I got a whole lot more.

Looks like someone squashed that picture. The tractor doesn't look any higher than a H. But you couldn't get an Elwood kit for a H.

The easiest way to get 4wd is to tap into the brake covers and pull power from the bull pinion shafts. I use the plural form because you would then run two driveshafts to the double pumpkin front axle. I think Chevy built Army trucks like that in WW2. Or run one driveshaft and find a way to lock the IH axle. I have already thought about the latter setup and may get around to it. I have done some preliminary work as shown below.

Wardner,

Explaine more about the Chev Army Truck (double Punkin) axle. I have never seen one with two differential chunks.

Harold,

You are putting me on a spot here. It's been at least 20 years since I saw that truck at some show.

It wouldn't be hard to take two Dana 60 axles and use the short sides connected by a empty pipe section. The splined side gears in the differentials would be locked to the carrier.

I am not considering this option so I haven't thought it out carefully. It also seems possible that if the two pumpkins were locked together with a dog clutch or a sliding splined coupling, you could have power to all four wheels with no slippage on any corner. Of course, you wouldn't be able to steer either. I have a Ford F350 with ARB air lockers on both ends of the truck. It won't steer worth a damn when compressed air is sent to both axles. Might take a football field to turn 90 degrees.
 
Here's a picture of a County Ford (made in England) with two driveshafts. County also converted IH tractors to 4wd but I think they only used one driveshaft.

By the way Dan,

That axle on the M is a WW2 Deuce-and-a-Half front axle. Elwood only had to drive down the road a bit to the Rock Island Army Supply Depot to get them.
 
I bought it new in a wooden crate at an IH parts and service dealer. They had bought it at auction from another IH dealer that went out of business in MA. Can't remember what I paid but it was probably around $100.

IH made several different right angle PTO adaptors. They all use the same housing. They were first seen on 300 Utilities. The input spline and ratios differ. One recently came up on eBay. I wanted it, but the owner refused to ship, so I couldn't bid. I have seen them go for $50 to $700.

The picture below shows it mounted to my 660.

hi, I have seen this tractor at a tractor show located at Lagrange Indiana. If I can remember it"s from Goshen Indiana. It was real nice to see up close

There is one in Tipton or Kempton, IN, can't remember. Don't know if that is near Goshen. The owner is a member of the Indiana Chapter. I would think it will be at the RPRU this week.
