Abstract
A power seeding rate adjustment mechanism for a seeding implement has a threaded lead screw that is rotated by an electric motor. A nut threaded onto the lead screw is fixed to the shifter lever such that when the lead screw is rotated, the nut translates along the length of the lead screw to pivot a shifter lever. The shifter lever is in turn coupled to a seed meter drive shaft to move the shaft transversely, thereby moving fluted feed wheels in or out of the seed cups. A switch carried by the operator in the pulling tractor actuates the motor. The adjustment mechanism enables the operator to make adjustments on-the-go without stopping or leaving the tractor. The motor can be disengaged from the lead screw and the screw turned by a hand crank for manual adjustment in the event of a power failure to the motor.
