Problems solved by technology
[0002] Existing blades for lawnmowers on the market are elongated and have mowing blades on both sides. Since the blades are linear, thicker or tough grass stems will quickly fade away due to the limited contact time with the blades. The blade slides over and leaves the blade, not easy to be cut off
And when the existing blade is provided with sawtooth on the outside of the rectangular cutter body to cut off the branch and trunk, because the cutter body rotates, the contact area between the sawtooth and the branch and trunk per unit time is small, so it is difficult to cut off the larger diameter branch and trunk

The invention discloses a novel mower blade. The novel mower blade comprises a cutter body, a middle hole, left sawteeth and right sawteeth. The novel mower blade is characterized in that the middle hole used for being fixed to a mower is formed in the middle of the cutter body; the left sawteeth and the right sawteeth are arranged at the two ends of the cutter body respectively and located on theouter sides of an arc of a concentric circle, the arc length of the left sawteeth and the arc length of the right sawteeth are each a quarter of the arc, and concave arc-shaped cutting edges are arranged on the cutter body. The left sawteeth and the right sawteeth are arranged on the outer sides of the arc of the concentric circle, and the left sawteeth and the right sawteeth are driven by a motor to rotate, so branches and trunks with large diameters can be effectively sawed off; and meanwhile, due to the fact that the cutting edges are in a concave arc shape, the contact time of straw and the cutting edges can be greatly prolonged, and straw cutting efficiency is improved.
Description
technical field [0001] The invention relates to a lawnmower accessory, in particular to a novel lawnmower blade. Background technique [0002] Existing blades for lawnmowers on the market are elongated and have mowing blades on both sides. Since the blades are linear, thicker or tough grass stems will quickly fade away due to the limited contact time with the blades. The blade slides over and leaves the blade, making it difficult to cut. And when the existing blade is provided with sawtooth on the outside of the rectangular cutter body to cut off the branch and trunk, because the cutter body rotates, the contact area between the sawtooth and the branch and trunk per unit time is small, and it is difficult to cut off the larger diameter branch and trunk. Contents of the invention [0003] The present invention overcomes the above-mentioned deficiencies in the prior art, and the purpose of the present invention is to provide a novel lawnmower blade that is convenient to car...
