手扶拖拉机牵引单向双铧犁作业时,一侧驱动轮在未耕地上,另一侧驱动轮在犁沟内,两轮与地面间的附着系数不同,打滑率各异,致使机组常向一个方向偏驶。对于东风一12型手扶拖拉机可进行以下的调整加以解决:调整牵引架上左右两个调整螺钉与中间连接架之间的间隙值(摆动间隙),681型单向双铧犁调到1.5mm左右,1LS一220型和701型单向双铧犁则调到5 mm左右。在犁耕过程中,如发现拖拉机仍向右偏驶,可将两个紧固螺钉松开,旋短左调整螺钉的伸出部分,旋长右螺钉的伸出部分。直到放开扶手架机组能沿沟壁正常行驶为止。
开沟作业
一般手扶拖拉机配置的主要是1KSQ一35A型(前置式)或1KSH一35A型(后置式)小圆盘式开沟机,主要用来开挖田间排水沟。开沟作业直线性差的主要原因:刀盘平面对称中心线与手扶拖拉机驱动轮轴中心平面偏差超过规定(1KSQ一35A允许偏差8mm,1KSH一35A允许偏差5 mm):刀盘扭曲变形,机架变形歪斜.犁刀安装错误,犁刀断裂、脱落等。应注意检查、矫正刀盘和机架。正确安装旋切犁刀,认真调整好刀盘位置,发现犁刀断裂、脱落,应立即停机熄火.更换部件。
