1.割刀阻塞 (1)地面上的石块、木棍或钢丝等物卡入割刀,使割刀不能运动。这时应立即停车熄火,清除障碍物。 (2)割刀间隙过大,导致塞草。动刀片与定刀片之间正确的剪切间隙:前端为0～0.5 mm,后端为1.0～1.5 mm。间隙过大,禾秆切割不断,会阻塞割刀。要针对间隙变大的原因或将割刀及护刃器加以紧固,或解决螺栓及刀杆变形等问题。 1. Cutter blocked (1) The ground stones, sticks or wire and other objects stuck into the cutter, the cutter can not move. At this moment, stop the vehicle and turn off the fire immediately to clear the obstacles. (2) knife gap is too large, leading to plug the grass. Correct cutting clearance between moving blade and fixed blade: front end 0 ~ 0.5 mm, rear end 1.0 ~ 1.5 mm. The gap is too large, straw cut continuously, will block the knife. To address the reasons for the larger gap or the knife and the guard to be tightened, or to solve the problems such as bolt and arbor deformation.
