犁铧是铧式犁的一个主要零件,也是最易磨损的零件。试验证明,铧刃厚度每增加1mm,犁耕阻力便增加10％。因此,使用中应注意犁铧的磨损情况,当铧刃厚度超过3mm,应磨刃,以减小犁耕阻力,降低油料消耗,保证耕地质量,当犁铧宽度被磨损到犁托的下缘与沟底土壤接触时,应更 Plowshare is a major part of the plow and also the most wear-resistant part. Test proved that, for every additional 1mm blade thickness, plow resistance will increase by 10%. Therefore, the use of plowshare should pay attention to the wear and tear, when the Hua blade thickness of more than 3mm, should be sharpened, in order to reduce the plowing resistance, reduce fuel consumption and ensure the quality of arable land, when the plowshare width is worn to the lower edge of the plow care and ditch Bottom soil contact should be more
