Abstract

A sod cutter (10) is disclosed including a frame (12) formed by welding the free edges of mount, frame and end plates (46a, 46b 46c) bent relative to one of two side plates (46) to the corresponding edges of the other side plate (48). An axle assembly (160) is pivotal relative to the frame (12) by a depth adjustment lever (198) between a working position where wheels (16) carried by the axle assembly (160) engage tubular members (168) slideably and nonrotatably received on a drive shaft (166) and a transport position where the wheels (16) are spaced from the tubular members (168). A U-shaped handlebar (210) is positionable between an operating position for grasping during operation and a storage position for lifting and handling. A U-shaped control (212) is pivotably mounted in front of and above the U-shaped handlebar (210) for actuating the throttle of the engine (18). A threaded lock (192) provides a connection between the handle mounting tube (180) and the mast (214) of the handlebar (210) and is not threadably removable by a spring pin (196) extending from the lock (192) and received in a gap defined between the mounting tube (180) and a locking plate.
