KUBOTA BY LAND PRIDE: The PS20 is a seeder unmatched in the market. First, the unit has both a quick attach skid plate hitch AND a 3-point hitch, meaning that it can be attached to a skid steer or a tractor, making it a versatile tool for rental yards. Second, the patent-pending bi-directional seed cups allow the unit to travel either forward or backward without fear of damaging the cups. The two packer wheels are 9.5" diameter and also serve as the drive for the seed metering system. The seedbox capacity is approximately one bushel/foot and is water tight with a built in agitator to keep the seed from bridging.
