[0002] The lawn mower, also known as the lawn mower, consists of a cutter disc, an engine, a running wheel, a running mechanism, a blade, an armrest and a control part. It consists of a parallel four-bar lifting device, a frame, a left and right single-wing weeding device, a whole machine deviation adjustment device, a comb tooth rotating bevel gear speed-increasing transmission mechanism and a comb tooth profiling depth adjustment device; the efficiency is 8 to 10 times higher than that of manual weeding, the seedling injury rate is low, and the seedling removal cleaning rate is high.

[0003] At present, the mowers on the market are mainly divided into two types: reels and rotary cutters. Reels are composed of multiple rotating blades, which work together with a fixed lower blade to cut like scissors. The rotation of the reels and the cooperation of the lower blades cut the grass blades like scissors. They are not suitable for processing thicker grass and need to be mowed regularly to maintain the best effect. The efficiency is low when processing large areas of lawn. Rotary cutters are installed horizontally, and the blades rotate rapidly around a central axis. The high-speed rotating blades are used to cut the grass blades through collision. The cutting method of rotary cutters may tear the grass blades, increase the risk of pests and diseases, and after the grass blades are torn, the top of the lawn may appear uneven, affecting the appearance. To this end, we provide a blade structure to solve the above problems. Utility Model Content
