A 行走式拖拉机 is a good helper for farmers. The walking tractor machine with different farm tools can achieve multiple functions. The walking tractor is light, flexible, and easy to operate, and is suitable for operation in different land conditions. Be sure to pay attention to maintenance when the walking tractor is frequently used, and repair it in time when there is a problem. Correct use, maintenance, and repair of your walking tractor are to maximize the benefits of your tractor. Here are a few common faults and maintenance methods for walking tractors.
当行走式拖拉机出现故障时，通常可以通过“听、看、闻、触”来判断。
Listen: change the engine speed, listen to whether it is stable at high and low speeds, and whether the exhaust sound is normal.
Look: observe whether there is any change in the exhaust, smoke, oil color, etc., and whether there is oil leakage, air leakage, and water leakage.
Smell: use your nose to smell smoke, burnt smell, and oily smell.
Touch: use your hands to understand the temperature of the water tank, bearing heating, component fixation, and high-pressure oil pipe pulsation.
关于行走式拖拉机的一些常见故障，下面分别介绍排除方法。
农业机械附件工具与行走式拖拉机分开
The hooks and bolts of walking tractors are easy to break, so the agricultural tool parts and the tractor are out of joint, and accidents of machine damage occur. Install a new safety hook between the tractor’s towing frame and the tow pipe of the agricultural tool parts to solve it properly. Before each use, check whether the hooks and pins are installed well.
首先，用厚度为8-10厘米的平铁焊接成钩形，然后用4个10-12厘米的螺栓固定在农具管上。再制作一个牵引架销，将原有钩和新制作的钩一起安装在此销上，确保两个钩可以上下左右滑动。然后，在行走式拖拉机的牵引架和拖拉管之间安装两个易拆卸的环链，以确保即使在行走式拖拉机运行时，原有牵引架、螺栓或钩断裂，也能安全使用。
离合器未完全分离
原因多为分离杆球与分离轴承间隙过大或拉杆过长。可通过调整间隙或缩短拉杆解决。如因摩擦片变形、离合器轴磨损或轴承盖工作坡过度磨损等引起，可通过更换摩擦片、电焊修复或更换轴花键和轴承盖解决。
自动关闭
原因是档杆行程过小，无法达到稳定位置。可以检查换挡杆、销钉、销孔等，进行调整。有时可能是定位钢球和定位槽磨损、弹簧力减弱、档杆变形、盖子变形或齿轮板偏斜。更换钢球、弹簧或修复定位槽，调整档杆和齿轮板。
制动失灵
多由制动环和制动杆凸轮磨损或制动杆与调节螺母调节不当引起。应修理或更换零件，并调节制动杆和螺母。
行走式拖拉机偏差
原因多为轮胎气压不一致或磨损不均。应将左右轮胎充至规定气压。如某一轮胎严重磨损，应考虑更换。
电气元件故障及处理
电磁铁不工作的原因是电路接触不良、线圈烧毁、保险丝损坏和整流桥损坏。因此，平时应多检查电路，及时发现问题并修复，更换电磁线圈、保险丝芯和整流二极管。
