A lawn edge trimming machine or edger is described wherein cutter blade height is controlled by relative angular adjustment of an opposed pair of handle grip members used by the operator in propelling the machine. The cutter adjustment mechanism includes coaxial pivotal means surrounding the take-off shaft and carrying a rocker arm rotatively supporting the cutter blade for belt connection with the drive shaft, the arrangement being such that the rotative axis of the cutter blade is in the vicinity of that of the ground wheel at the same side of the machine, for simplicity and compactness of structure, for improved performance, and for enhanced maneuverability. A protective cover guard surrounding the cutter blade assembly provides maximum protection against flying objects propelled by the cutter blade, while at the same time, being comprised partly of wire mesh screening, affording a view of the rotating cutter blade to the operator during use of the machine. Foot-pedal controlled means is provided for converting the machine between vertical and oblique planes of operation of the cutter blade, for correspondingly different modes of cutter operation.
