1957 420c
This is my lil 420c. It's a '57 ser. number 107,xxx
Recently converted it back to 6v pos. ground and reworked the accesories on the motor. Recent job to tackle was the clutch casing on one side that was cracked and to tighten up the carriages for the tracks.
It's a working tractor.. so as of now it's not kept real pretty.. (the battery box etc). I think it's just too fun to play with to have restored.

Yeah.. that's actually why it came off the site I'm clearing and grading.. to tighten the tracks.
Here is what it looks like right now...
The age old.. one thing led to another.. and then.. we're this far why turn back.. etc etc etc. (Adjusters wouldn't adjust due to being bent badly and having run over rocks destroying the threads... pulled the idlers.. then to fix a cracked lift arm we had the whole carriage out.. then.. we were close enough to fix the clutch housing.. you get the picture)
Ohh well.. it's fun learning and I'll know it's done right by the books when I put it back together.

It will be hard on the sprockets and the bushings. 40 has 1 1/2" bushing, 420 is 1 9/16" bushing. It is only 1/16", but it is cumulative, on the second bushing contacting the sprocket, it is 1/8" off, on the third, 3/16" and so on. It effectively makes the track out of pitch. Now add in some wear on the pins and bushings, and it makes it that much worse.
Measure your bushings, and you will be able to tell which rails you have.
