ABSTRACT:
A plug pusher, mounted to a mower of the type having a lift frame, pushes turf core plugs from an aerated turf surface. The plug pusher includes two L-shaped, elongate pusher elements, each having a horizontal first leg and a vertical second leg, mounted to the vehicle for being raised and lowered by the lift frame. The first leg of each pusher element extends forwardly from the second leg and lies on the turf surface so as the vehicle moves the core plugs gather in front of the second leg and on top of the first leg. The pusher elements are configured and are mounted to the mower to permit limited movement relative to the mower and each other to accommodate uneven surfaces.
