REEL LAWN MOWER WITH MAIN BODY, REEL CUTTING UNIT, AND CONNECTION STRUCTURE FOR CONNECTING REEL CUTTING UNIT TO MAIN BODY SUCH THAT REEL CUTTING UNIT IS ROLLABLE

摘要

A reel lawn mower which has a connection structure for connecting a reel cutting unit to a main body. The reel cutting unit has a spiral cutting reel which is rotated by a prime mover to cut grass together with a bedknife. In the connection structure, in order to connect the reel cutting unit to the main body so that the reel cutting unit rolls around a virtual horizontal line perpendicular to the shaft center of the cutting reel in the center of the axial direction of the cutting reel, the reel cutting unit includes a connecting arm with an arc portion shaped so as to follow a virtual arc centered on the virtual horizontal line. The connecting arm is slidably supported so as to prevent the arc portion from coming off the virtual arc.

主权项

1. A reel lawn mower comprising:
a main body of which a running direction is determined; a reel cutting unit connected to the main body and located on a front side in the running direction; a pair of rollers which are located on the reel cutting unit rotatably around a horizontal axis perpendicular to the running direction, to support the reel cutting unit at front and rear positions thereof in the running direction; a spiral cutting reel which is located on the reel cutting unit between the pair of rollers rotatably around the horizontal axis perpendicular to the running direction; a bedknife which is located on the reel cutting unit and touches the cutting reel under rotation and mows a lawn together with the cutting reel; and a connection structure which connects the reel cutting unit to the main body, wherein the reel cutting unit is rollable around a virtual center point which is in a vertical projection plane covering the cutting reel with a minimum usable diameter and located in a center of an axial direction of the cutting reel, as a rotation center.
