One of the many reasons why my dad liked his John Deere B was the lack of battery. He also liked the flywheel start with pet cocks. Very easy on back and can use two hands.
How is are the Farmalls to start? Are there pet-cocks? The McCormick Deering 10-20 required a lot of heft to start which admittedly is short supply from office workers.
As for bands, I didn't realize you'd make them removable. I thought I saw folks weld them right to the lugs.
