convert 140 fertilizer drive to electric

jacks · Jul 16, 2011

Has anyone converted the fertilizer drive on a Farmall or IH 140 to electric drive? About how many RPM"s should the fertilizer shaft turn? I have the fertilizer unit on a tractor that I recently bought, but am missing the countershaft drive. I would like to set it up with an adjustable speed electric drive motor.

My best suggestion is to use a form of wheel drive. The setting of the speed and powering of the system is a task for a servo engineer. The 140 electrical system is not very clean in terms of Interference and transients, it would need to be conditioned. The shafts turn in proportion to ground speed and application rate, so a single speed is not usable. a servo motor, controlls, and drive amplifier is needed, as well as a "motor" cxapable of driving the shaft.
A wheel driven by the ground would do well in making the application work as needed. As the wheel was lifted the fertilizer would stop. As speed changed the rate would remain proportioned.
By best input. Jim

You arent going to get a DC motor to run it so why dont you go to a hy motor then you can vary the speed.

Gene,I thought of using a hydraulic motor, and I don't believe that it would be too hard to set up. I know of someone that already has theirs running on a DC motor, and I may get the chance to see how they are doing it. I thought an electric motor would be easier and less expensive. Thanks, Jack

The problem will be the speed of the fertilizer drive has to change with your ground speed, otherwise the rates will be off. That will be hard to do with a plain motor.
