ABSTRACT:
A machine for slitting turf or soil and inserting particulate solids in the bottom of the cut slits. This machine consists of a propulsion unit, cutter blades, a material hopper, a material flow control valve, a set of rotary material supply vanes driven by a measurement wheel in contact with the ground, a set of insertion tubes mounted on a gimbal assembly which allows the insertion tubes to free float independent of machine tip and tilt motion. The insertion tubes therefore follow the bottom of the cut slits, dispensing the solid material therein. Also disclosed is a novel insertion tube.
