<p>PROBLEM TO BE SOLVED: To provide a tiller capable of corresponding softly to even a deformation of a tilling pawl part and the kind change of a rotor plate, if any, thereby to remove a deposit on the tilling pawl part.SOLUTION: A rotary brush 52 is interposed between a rotor plate 44 and a soil-removing cover 31. The rotary brush 52 comprises: a brush shaft 51 parallel to a tilling shaft 42; and a brush part 53 made of nylon or a metal extending from the brush shaft 51 to the periphery. In response to the power (or the rotation force of a prime mover 33) from a transmission mechanism housed in a transmission case 34, the tilling shaft 42 and the brush shaft 51 rotate in the same direction, and a plurality of rotor plates 44 attached to the tilling shaft 42 rotate so that a rotary brush 52 rotates in contact with the tilling pawl 46 while a tilling pawl part 46 of the outer circumference of the rotor plate 44 rotating, thereby to remove soil and weed having stuck to the tilling pawl part 46.</p> |
