ABSTRACT:
An athletic field line cutter (10) has a chassis (12) including a plurality of wheels (98-104) for locomotion across the ground. A cutter head assembly (18) is mounted on the chassis (12) and includes a plurality of cutter blades (92) mounted on a rotating axle (30). Axle (30) is mounted parallel to the ground. An engine (14) is connected to axle (30) for supplying power to the axle (30) and the cutter blades (92). An operator station (60) at which an operator (90) directs the apparatus over the ground is in line with the cutter head assembly (18) and the line of travel of the apparatus (10). Rotating axle (30) has a section (126) which is polygonal in shape, and cutter blades (92) have central polygonal holes that closely fit over this polygonal shape. Blades (92) are angularly fixed with respect to each other.
