Background technique

Multi-functional grass guards are widely used in harvesters. Its function is to separate agricultural and animal husbandry crops or to prevent pasture from being squeezed out of the cutting table or flying out of the cutting table and parts of the cutter to cause grass blocking, grass plugging and grass clipping. The weed divider or the grass retainer on the existing mower mostly adopt the guard plate structure on the grain combine harvester or the crop harvester. Some lawnmower cutters are equipped with a profiling plate at the bottom, which has a simple structure. There is only one arc-shaped bent plate, and the bolts are fixed to the bottom ends of both sides of the cutter. Imported New Holland reciprocating lawn mower cutters on both sides are designed as curved panels, and the front end is streamlined and pointed to form a grain divider, which can only be used when the lawn mower is working forward. Separate pre-cut and unmown non-tangle forage. The existing lawn mower grass retaining board has simple structure and single function, which is prone to problems such as clogging of the cut pasture on the side parts and parts of the cutting table, large loss of the cutting table and irregular stubble cutting.
