LAWN SCARIFIER AND RAKE Abstract of the Disclosure A turf scarifier and raker includes a housing with an elongated upright handle and having suitably positioned wheels designed to permit traversing movements over turf while the operator is in a standing position. The housing has an electric motor positioned in essentially the same plane as a tine assembly driven by the electric motor. The tine assembly has a plurality of tines which extend through an opening at the bottom of the housing. The tines result from a plurality of torsion coil springs having radially extending active ends that are serially threaded on rods arcuately and radially located about a central axle of the tine assembly. The active ends come into contact with the turf when the device is operated. At the same time, the other ends of the springs are inhibited from turning torque by lying in abutment against the central axle.
