ABSTRACT:
A turf injector includes a plurality of slitting knives followed by a plurality of nozzles for injecting chemicals into the ground. Each slitting knife is reversible to bring one of two longitudinally extending cutting edges into use, thereby extending the life of the knife. In addition, each slitting knife has dual sets of mounting holes received on a set of fixed mounting pins to further adjust the vertical position of each knife on the frame. This allows for wear of the cutting edge of the blade and further extends the life of the blade. The hole and pin mounting system desirably mounts each knife with its cutting edge held at a 15.degree. angle of inclination relative to the horizontal to minimize disruption of the turf and the length of the knife.
