Looking at 4020's on the Auction time website I came across this one. Is that a "sprocket" on the RH axle? If so, what is it's purpose?

nice looking tractor. never saw a gear like that on one . we have 4320 no sprocket

On two cylinders, there were sprockets used like that on occaision to drive a side-dress attatchment on a cultivator, or even cultivator mounted planter units.

I'm guessing that's what it is for.

Looks like maybe #50 roller chain.
Those attachments usually were driven by flat link chain.
No idea what that one was for.

I suppose it could also be some sort of speed metering device. They might have taken the sensor off and left the sprocket. Could have been a planter or sprayer tractor.

'Long time ago a john blue pump used to be driven by sprocket like this one.

Maybe a John Blue fertilize pump for side dressing??

These are the sprockets I'm use to seeing on axles , used to drive rear [or front mount on cult.] dry fertilizer side dressers . Use flat link (detachable) chain.. roll chain sprocket is unusual ....

We had those on our 1950's A's and G's to drive the planter boxes on the rear tool bar. Used flat link chain.

Looks like a John Blue side dresser or planter. Thanks guys, had never seen anything like that before.

Nice looking tractor . Wonder why they put 4WD in the spec section on that tractor? Obviously not a four wheel drive.
