Lawn vehicles are the necessary equipment for golf courses and garden maintenance units. They are used frequently and at the same time, various kinds of failures also occur. We invited Zhang Zhiqiang, a machine repair specialist at the training department of the Lvyou Group headquarters, to communicate with readers about the faults of lawn vehicles that are easily overlooked in daily use. Case number one Brake switch deformation caused the device can not start A customer called to reflect that the lawn car could not be started and required urgent repairs. After Zhang Zhiqiang and other crews arrived at the scene, they made initial inspections based on their feelings and experience: The battery was on electricity, the wiring and wiring connections were all intact, and the seat switch was not problematic. When the brake safety switch was viewed, the switch was found to be skewed downwards. According to the inspection result, it can be inferred that the brake pedal is pressed down for a long time to displace the fixed base of the switch downwards, resulting in that the contact position of the brake safety switch cannot be reached, and no closing action is achieved, so that the lawn vehicle cannot start. After restoring the position of the brake safety switch fixing seat, a reasonable distance between the brake device and the top brake of the safety brake switch is achieved, so that the lawn vehicle resumes its normal start. Case 2 Loose PTO lines prevent the cutter head from rotating A lawn team of a green team can start and walk, but the cutter can't rotate and can't cut grass. After Zhang Zhiqiang received the mission, he first came to the scene to ask about the use of the car and the failure. It turned out that their grass was not very flat, and the lawn carts were quite bumpy. They suddenly failed and could not be used. Since the lawn vehicle can start, troubleshooting the cause of the fault is much simpler. Check the key switch, cutter PTO switch and other components as usual. When looking at the PTO line, the cause of the failure was found because the position of the PTO circuit wiring plug was loose, and the contact was incorrect and an open circuit was formed. Insert the real line plug, and then use the tape to strengthen the fixed, close the cutter PTO switch test machine, work conditions returned to normal. Case three Reverse switch insulation board aging can not cut grass A company's lawn cart could not be started. Zhang Zhiqiang first learned about the situation using the lawn cart master. According to the master, the fire broke out at the beginning and sometimes it was possible to walk after it was started. However, when the meadow was cut and the grass was cut, the machine went off. Checking the circuit and the component switch at the time was also a very difficult task. It was entirely without any checking tools. All work experience was checked by one line and one line. When inspecting the reversing line, it was found that the reversing switch insulation rubber sheet was aging. Therefore, in the case of not reversing the vehicle, the insulating plate was in a state of separation. When the cutter head was shaken, the insulating plate did not provide insulation. Reversing the switch base directly hits the iron causing a short circuit. After finding the cause, Zhang Zhiqiang replaced the insulation pad with a thick waterproof insulating strip. After the treatment, the lawn cart can be trimmed.
