ABSTRACT:
A walk-behind garden tiller having power driven ground wheels and a single row of tines which are driven at relatively high speed in a direction counter to that of the drive wheels, whereby the tines cut upwardly through the untilled soil at the working face with less power and in the event of contacting an obstruction tend to move the machine in a rearward direction be reason of reactive forces acting upon the machine through the tines. A drag shield is pivotably mounted rearwardly of the machine for dragging along and smoothing the soil after it is tilled and for providing a protective barrier between the operator and a rear exposure to the power driven tines. The drag shield has a length greater than the vertical distance between its point of mounting on the machine and the bottom peripheral level of the tines and, in the event of sudden rearward movement of the machine during tilling, is adapted to anchor in the soil and thereupon be pivoted about such anchor point to elevate the rear of the machine, reducing tine contact with the soil and any obstruction.
