Could anyone tell me what the RPM speed would be of the driver shaft on on JD 7000 planter at say 4.5 mph? I am mounting a John blue piston pump to apply liquid N. I'm trying to figure out how fast the main shaft will be spinning at planting speed to determine the sprockets or "transmission" required to get me withing the operating rpms of the John Blue pump.
