Started to replace the water pump on my 53 John Deere 50 tractor and noticed the bottom tank has a rod in the front that looks like it moves in and out like a plunger anyone know what it's for? Never seen one before Thanks Howard

On the early ones that was to run the shutters for the radiator. Most are unhooked and/or shutters removed.

It's not shutters its built into the bottom of the tank I will try to get a picture of it thanks Howard

Like i said. I try woring it differently. That thing was used to operate the shutters.

Mike is correct, there was a linkage & pivot rod that attached to the in radiator thermostat that operated the shutters. Very few worked for
long. I remember my father saying, if you need to have it work, better oil the shutters everyday...

Thanks that makes sense just new to me never seen one before

As below, it is operated by a sylphon (thermostat) to open the shutters. I was lucky and got a NOS unit and a set of operational shutters for my 60. Spent a lot of time cleaning up the shutters, but by golly they work !

Howard, I'm guessing your shutters have been removed?

I flipped my shutters upside down and hooked a cable to them so I could manually control them from the operator's position. My 50 runs better when I get the water temperature up around 180 degrees.
