An agricultural planter for metering seeds for row crops includes a main frame in the form of a sled with transport wheels which can be selectively raised and lowered for transporting the planter and a tool bar for mounting a plurality of implements. A planter unit for the planter machine includes a main frame having a pair of vertically extending shanks for connecting to the tool bar, a mounting bracket for a seed shoe, and a bracket for a press wheel, a vacuum operated seed dispensing device with the vacuum provided by a vacuum fan mounted on the sled and powered by hydraulic motor with fluid from the main hydraulic system of the tractor. A jack shaft mounted transverse to the sled for powering the implements is driven by a ground wheel including a frame having a pair of reversible tool bar shanks and a drive transmission including a countershaft providing the pivotal support for the frame of the ground wheel.
