Abstract:
A tiller comprising:an engine for producing a motive power; a transmission case mounted to the engine and having a transmission mechanism housed therein; a rotor shaft rotatably mounted on the transmission case and connected to the transmission mechanism so that the rotor shaft can be driven by the motive power transmitted from the engine via the transmission mechanism; tillage tines mounted on the rotor shaft to undergo rotation in one direction to perform a tilling operation while propelling the tiller in a forward direction; a fender disposed above the tillage tines to cover the tillage tines; a plurality of bolts connecting the fender to the transmission case, the bolts each having a portion projecting downwardly from the fender; and a guard member located on an upstream side of the projecting portions of the bolts when viewed in the direction of rotation of the tillage tines and extending downwardly from at least one of the transmission case and the fender to a level lower than the projecting portion of each of the bolts so as to guard the projecting portions against a foreign object thrown upwardly by the tillage tines during the tilling operation, the guard member extending in a widthwise direction with respect to a longitudinal centerline of the tiller a farther extent than that of the projecting portions of the bolts in the widthwise direction.
