Leesburg, Ohio | ........"B's to 4020's all could use the same narrow frontends and oil filters".........
Not quite. Filters, yes, they were all the same. Roll-a-Matic front ends, no.
The type shown above will probably work as far back as the 20 series two-cylinder, and maybe a few of the later "early numbered series" tractors. Before that, the Roll-a-Matic was part of the tall vertical solid steering column that went from the front wheels all the way up thru the steering box on top of the radiator.
We broke several front-ends out of our 1952 model 60 tractor, and had to hoist the front end up to the sky to drop the Roll-a-Matic and shaft out of the steering column housing. But the Roll-a-Matic didn't break...it was always the cast iron frame that broke behind the radiator, in front of the engine block.
IIRC, there were also two types of the Roll-a-matics shown above...a heavy-duty one used on the 4020, and a lighter duty one used on the 3020/2520. They would both interchange on any of those tractors, however. | |
