Farmall M Duals.

eye4iron · Mar 28, 2012

Has anyone tried to add another set of cast spokes to the M axles and then mount rims and tires? Would this work for a dual set up? Or would there be an interferance problem.

They work inside dished in outside dished out. An M does not need duals unless you ar in very sovt soil, but they do work. Jim

You forget about the looks factor. :lol: I plan on running a landside dual this fall, but I admit it is mostly for looks.

For many years we ran a pair of Super M's with dual 14.9 x 38's mounted on cast centers.

Like Jim N says mount the inner wheels dish side in; the outers dished out. Works great....and it looks kinda cool too!

Years ago i did it with my 200 and it worked very well as it is better to float over the ground than go through it! Later in the summer and fall you can where wheels fit the ground and thats why Quad Trac's are so popular!Float,don't burrow! Bud.

we ran duals on our SMTA when doing spring tillage for many years. Mostly fall plowed but some spring plowed. I would disagree that an M didn't need duals, you could see where the rear wheels went behind the disc or field cultivator with singles but not when you ran duals. We had M&W dual hubs and the duals were stamped center rims.

Obviously you have never put up hay in the sandhills of Nebraska, nor have you ever put much time on any of these old work horses.

Janicholson · Mar 28, 2012

With respect, do not assume you know me well enough to comment on my time on top of Farmalls. If you read my comment, I indicated flotation (soft ground issues) and take to the bank that a loaded set of duals on a M can allow you to pull things in first that tear up the finals. Jim.

yea it works my grandpas 44 m has a set of duals made from cut off steel wheels (spoke rims) but you have to have the inside wheels dished in and set narrow to have enough axle to put on the second set of wheels and then a long socket extention to reach the inside wheel clamp bolts.

I KNOW you can do the "dished in" and "dished out " with the cast centers on a SUPER M,but I DO NOT know if the axles are long enough on a standard M???? (It looks like a few answers below pertain to Supers.)

mkirsch · Mar 29, 2012

Yes Mike, it works just fine. The book "150 Years of International Harvester" has at least one photo of an M set up this way. That photo has made it into a few other IH books as well.

My problem is, nobody pays attention to the front end. 40% of the tractor's weight is on those skinny little tires, yet nobody duals them up.

I will, how do you do it?

The tape measure says it will work on my MD, but I haven't actually done it yet.

Bud DeLong · Mar 29, 2012

What happne's to that 40% when you start pulling from the drawbar? Bud.

mike1972chev · Mar 29, 2012

Cool!

I will have to look that book up.Bet it has some awesome photos in it????

I have seen a tractor pic SOMEWHERE where the bolted an extra wheel in the front???

It looked like they "studded"the front hub in all 3 holes with some long studs and stacked an extra wheel/tire right on top. I do not know how stable that set up would be??? Dont know if it had any INNER support in the rims or not?(couldnt see it in photo.)

mike1972chev · Mar 29, 2012

The landside dual was USED/NEEDED on this tractor last fall.(Showed this pic before.)

It was a little moist that day.This tractor had good traction.

If you stop and think about how a tricycle front is configured, with the tires being closer together at the bottom than at the top, then add an extra wheel/tire combo to the existing combo, wouldn't that cause the OUTER wheel/tire to carry MOST of the weight? And cause the tractor to set higher in the front?

LenND · Mar 29, 2012

Got a question for you guys. Does putting duals on an M cause any problems with rear axles. bearings, etc. from the extra width? This would be when using it for heavier field work. There is a lot of extra weighr on the end of that axle with the duals on, especially when turning.

I have seen a picture of that setup. I think they used a smaller outer tire.

Janicholson · Mar 29, 2012

There is no extra weight on the axle. The outer tires/wheels are self supporting, they support the axle and thus the tractor. Sharing the support with the inner set. Strain is present in the form of bending moment applied to the axle if the outer duals are driven such that they alone support the tractor and inner set. Not at all problematic unless there is extra weight on the tractor frame. For example a 3pt hitch or Fast Hitch retrofit, lifting a disk, would be enough to tax the strength of an axle or housing.

Go to www.caseih.com and look up Farmall M in the parts catalog. Then you can look at dual rear wheels as per genuine setup.
