A Brief Talk on Agricultural Machinery Maintenance Experience
Generally, the driver of the tractor thinks that the walking tractor will only reverse when downhill, which is not the case. When the tractor is driving at a high speed on a flat road, if the throttle is suddenly reduced, it may be reversed. Because the engine is no longer the power for advancement, it becomes resistance. The force that propels the unit forward is the inertia of the unit itself. The higher the tractor's driving speed, the greater the loading mass, and the faster the reduction of the throttle, the greater the inertial force generated, the more serious the anti-drive phenomenon, and the greater the possibility of reverse rotation. Therefore, do not easily pull the steering handle at this time. It is best to push the handrail by hand to turn it to the left or right as needed to achieve safe steering when the high speed throttle is on the flat road. Small diesel engines used in rural areas are sometimes used instead of fuel tanks instead of oil drums. This phenomenon occurs most often when several diesel engines share a common diesel engine. The drawbacks of this approach are obvious, such as the easy contamination of diesel oil, easy access to air in the oil circuit, and so on. In fact, several households sharing a single machine can negotiate a fairly good method of sharing fuel consumption costs. If there is no connecting rod corrector for the diesel engine, whether the connecting rod of the engine is bent can be checked directly on the diesel engine. Now take the horizontal type 195 diesel engine as an example to outline the inspection method as follows. Place the cylinder upright, remove the cylinder head, slowly rotate the flywheel, and observe the movement of the piston in the cylinder. If the piston always biases the direction of the cylinder wall at the front or rear end of the crankshaft in four strokes, the piston connecting rod set can be withdrawn from the cylinder liner, turned to 180o, and re-observed according to the above method. If the direction in which the piston is deflected is exactly the opposite of the result of the last inspection, it means that the connecting rod is bent and should be repaired or replaced with a new one.
