The present design relates to a lawn mower cutter support structure.
Characterized in the configuration provided with a spline groove 22 is fitted to the spline shaft 10 to the spline shaft 10, the center hole inner diameter at the same time and having the fit projections (21) in provided in the lawn mower bag end head 100 in hayeoseo the seating ring 20 and the fitting protrusion 21, the cutter 30, after the spline shaft 10, the cutter 30 is fitted so that holes 31 are formed embedded in the seating ring 20 sandwiched assembly is is seated on the spacer 40 having the spline groove 41 in the same time the center Sikkim close the cutter 30, the spacer 40, nut 60, the screw rod of the spline shaft 10, the end ( stably groove 52 to be fixed to the fastening 11) in the structure consisting of a nut housing 50 is formed,
The outer peripheral surface mounting protrusion 21 that the cutter 30 is formed in the seating ring 20 seated in the 1 to another cutter mounting protrusion 42 in the form a plurality of engagement projections 23, spacers 40 ( 30 ') a further form the plurality of engagement protrusions 43 1 to the outer peripheral surface so that it can be mounted, the cutter (30, 30' inserted in the holes 31 of inner diameter) to the engagement protrusion 23 (43) It characterized by further forming a geolhom 32 to be assembled.
The present design is configured as is the space 55 which, when it rotates at a high speed cutter 30 and the cutter (30, cutter 30, 30 'induces a vortex between) will be formed when the herbicidal action, long as the lawn mower blade (30) (30 ') it has become a very powerful vortex as fast air pass into the space (60) to induce a vortex when rotating working lawn mower at a high speed that it serves to support on the ground even if that is not the weeding will significantly feel the weight of heaviness or fatigue lawn mower is to follow a number of effects, such as much less.
