Hey,

I THINK I might KINDA have an idea on this one,but would like WAY more detail.(Need something NEW to learn today! :)

I notice the front hubs on 1947 M tractor picture #1 (rusty "worker"tractor) is different than 1951 M tractor in picture #2 (Shiny"parade" tractor)I am assuming somewhere AFTER 1947 the style of front hubs changed ??? (BYW,I see BOTH types of those hubs on ALOT of different years of Ms back and forth ?????)


Question #2: The REAR rims on the H tractor in picture #3(Tractor wearing all it's "winter gear") looks like it is running on "cut offs" OR F20 wheels ???? I have seen this more than once on Hs. Did ALL early Hs have F20 style rear wheels on them???

fixed vs adjustable. My '41 narrow front H has the adjustable, of course I don't know for sure if it came that way. A lot of times I see the fixed camped wheels on wide fronts.
 

The rusty looking M has the non-adjustable front wheels, and the shiny M has the Front wheels that are adjustable to accomodate different row-crop row spacings. As far as I know, those 2 options were NOT year specific.

The H in the other picture has "cut-off" or "cut-down" rear wheels. That H probably came from the factory on full steel rear wheels, and sometime later in its life the outer steel rims were cut off, and rims to accept rubber tires were welded onto the spokes. It was an inexpensive method used to upgrade the tractor to rubber tires.

Rubber tires were in short supply during the war years, so a lot of tractors were sold with steel wheels.
 
There are several 'war H' tractors in this area that were delivered on steel instead of rubber because of WWII restrictions. After the war, the rears were cut down and rims for rubber were welded on. They look just like that. Neighbor has a 1940 H that has had the normal cast wheel centers since new.

I don't think there was much of a problem getting rubber tires in '39, '40, or '41. I think the rationing took place in '42, '43, and maybe into '45.
 
those front hubs on the rusty tractor would apply to the standard w 6 tractor . the hubs on the painted tractor would apply to the super w 6 tractor. thats one way to tell the supers, they have those type of hubs.
but in the farmall line i dont know why they are mixed in the non supers. maybe there is a year when they got the newer hubs.
 
also forgot to mension that at the end of 1952 just before the supers came out it is possible to see these newer style hubs and the disc brakes on the standard w 6.
 
Could just be me, but it seems like the fixed style fronts always seemed to break or crack more than the adjustable-style hubs, especially for the 15 inch rims.
 
The adjustable hubs were an option at some point in time and then became standard. At what point I don't remember. My dad had a 47 H new from the factory with the adjustable front wheels. The rears in that picture are simply cut offs. My dad also had a early H with factory steel, he later converted the rear steel to rubber (cutoffs).
 
I have the non-adjustable hubs on my 49 H but I never checked to see if they have casting codes and if so whether they are correct. I had wondered which one came first too, so I'm glad you asked about it.

And to add, if you look at the front hubs on your Super, you'll notice they're thicker around the mounting hole than the same area on the adjustable M hubs.

BTW, what is that "thing" behind the parade M? It looks like some kind of outsized riding mower from space!
 
Come on now. I have one of those "space tractors" and its great for mowing in tight places. Pretty darn handy getting the loader off and on too.
I have 2 green ones...and they sure make shoveling cow stuff a lot easier.
 
Here is a set of cutoffs ready to go on someone's H. I elected to stay with the new hubs so I could add weights. Anyone interested?

Well Centex,since it IS GREEN,it must be ALIEN???? It is maybe trying to "probe" the M for intelligence on proper farming ?????
