[Farmall] F-20 tires

[Bob Currie]

The applications I have seen here in northern California were obviously set 
up for high clearance work but I don't know what kind of crop. There were 
many IH, JD, and Case high crops used in this  general area. Some factory, 
but many home made. On the Farmalls I saw, my guess is they were all done 
locally and in both cases, they had wide front axles with the original 
hubs, but had been adapted for pneumatic rims with 600 X 16 tires on one, 
and 650 X 16's on the other. And then the larger F&H wheels on the rear. 
The F-20 was originally an "NW", but not a cane tractor.  The 42 inchers 
were a great surprise to me. Same scenario but on an F-30 tractor. I don't 
remember the rear tire size, and I understand the tractor has sense gone up 
to live in the central Oregon area. Last year we found an F-12 with 40" 
round spoke rears, and sporting a Farmall "H" wide front  with 16" tires.
