摘要： Blade connecting means comprises a lug member and a retaining member. The lug member and retaining member are adapted to be secured to a mower shaft and to removably secure a mower blade to the mower shaft. The lug member has at least on one end a hook on which the blade is hung, and the retaining member normally engages and closes the hook of the lug member to retain the blade on the hook and, hence, on the shaft. The blade may be easily installed on or removed from the shaft by manipulating the blade to move the retaining member to a position where the hook is open, no tools being necessary to install or remove the blade.

摘要： This disclosure deals with a mower including means for removably attaching cutting blades to a rotatable shaft of the mower. The mower includes a generally horizontal rotatable shaft, means for rotating the shaft at a high speed, a plurality of cutting blade supports secured to the shaft, and one or more cutting blades attached to each of the blade supports. The supports are angularly and circumferentially spaced along the length of the shaft so that, upon rotation of the shaft, the blades cut a swath which is substantially continuous over the length of the shaft. Each blade support includes a member which is supported at one end only, a generally circular central portion which carries the blades during mower operation, and a free end portion which includes an offset or protrusion, thus forming an out-of-round cross section. Each blade has a hole formed therein, which is shaped to permit the blade to be slipped over the protrusion of the free end portion when the blade is placed at a certain angle relative to the free end portion. Once past the free end portion, the blade is moved to the central portion of the member, and its swings loosely on the central portion. The protrusion of the free end portion then retards accidental removal of the blade from the member.
