Unique John Deere Features at the 2023 National Pike Steam, Gas, and Horse Show (Open Fan Shaft A) 

A guy near us has a model 60 with a tachometer but I didn't realize the late As could be had with one. It also looks like that A had the same hydraulic pump and valve as a 60. Pretty cool.

The 435 has a 2 cylinder, 2 stroke diesel, GM model 253.

You didn’t mention that the ‘52 A had a 60 head and Duplex carb on it lol.

That teal colored earth mover at the end had a Detroit 2 stroke for reference on the 435 sound.
