Turf working machinery is the fastest growing and most distinctive type of machinery at present, and has formed its own independent system. According to the work content, the lawn machinery can be divided into two major categories: lawn construction machinery and turf maintenance machinery. Among them, there are many types of maintenance machinery, and specialized machinery with distinctive characteristics include lawn trimming machinery, lawn hole ventilation machinery, grass sowing root cutting machine, lawn sand coating machine, lawn sprayer, lawn fertilizer machine, and lawn finishing machine (cutting (machines, cleaners, crushers) and lawn irrigation equipment. The maintenance of turfgrass has many tasks, large workload, and high mechanical utilization rate. Without proper conservation measures, it will affect the normal performance of machinery, reduce work efficiency, and greatly shorten the service life of machinery. Correct maintenance of turf working machinery should follow the principle of "a center of gravity, two basic points". “A center of gravity†refers to the key conservation object of turfgrass maintenance, and the main focus of lawn machinery maintenance is the engine. The engine is the source of all power and must be given great importance. Do a good job engine maintenance to do the following: 1. Use suitable fuel 2, keep the exhaust port clean (clear dust, grass clippings); 3, remove grass clippings and dust particles in fan blades and fan housings to prevent overheating and reduce efficiency; 4, according to the intensity of use, regular replacement or cleaning of air filters; 5, clean spark plugs; 6. Keep the starter tight and operational. "Two basic points" refers to the daily maintenance of lawn machinery and special seasonal maintenance. Daily maintenance should do the following: 1. Traction or suspension of working machinery, pay attention to the maintenance of the tractor (engine, ignition system, cooling system, rotating device, differential, belt, hydraulic system, air filter, lubrication system, etc.); 2. The push-type machinery powered by small engines is maintained by the engine maintenance; 3, with the movement of the components before the operation and regular inspections, add lubricants; 4, for the blade of machinery (mowers, edge trimmer, dredging machine, grinder), check the cutting position, to ensure sharp, not in the operating area or outside the lawn, can not be free to put the hole knife; 5, on the belt or transmission chain, often check the degree of tension; 6, the battery is the power source of the machinery, often check the battery capacity, timely charging; 7. Cleaning after use (spray sprayer, fertilizer spreader, seeder, lawnmower, cleaner). Special season conservation (winter) should do the following: 1. For the engine, drain the fuel in the tank, drain the engine's lubricant, and inject clean lubricant; 2, for the ignition system, be sure to ensure that the battery is full of electricity, the battery poles painted with grease or similar protection, so as to avoid corrosion, if there is no heating in the place to save the equipment, in order to avoid freezing the electrode solution, remove the battery, Store in a warm place. Ignition system is best not to get damp; 3, for the transmission system, to check the amount of lubricant is appropriate, and to prevent moisture. 4, for the cooling system, to add new antifreeze; 5, for the hydraulic system, to check the amount of sealant and oil is appropriate, we must avoid the condensation of water in the hydraulic system; 6, for the carburetor, to drain all the gasoline in order to avoid gel; 7, for the rubber surface, in order to slow down the aging, the surface can be coated with a protective material; 8, for the metal surface, in order to avoid rust corrosion, all surfaces of equipment to be preserved in winter should be sprayed with a layer of paint; 9. For the cutting part, in order to avoid rust or etchback, a thin layer of lubricating oil or grease should be applied to the newly ground roller blades and bed blades; 10. For sprayers, open the reservoir and keep it dry and ventilated. To prevent freezing, be sure that there is no water in the pump cylinder; 11. For the duster, clean, dry and apply paint, lubricating oil or grease before storage; 12. For fertilizer applicators, be sure to wash away all residues, dry them, apply grease or grease and store them; 13. For rolling rollers, be sure to drain the water and keep it dry. 14, for automatic unloading parts and trailers, should be placed in a higher position to avoid the accumulation of water, ice or other debris, to prevent corrosion of metal or wooden surfaces. In addition, before using the machine, read the instruction manual carefully, familiarize yourself with the performance parameters (such as speed range, power range, etc.) and master the operating specifications. Exceeding the permissible use limits of the equipment is very dangerous for workers and machinery, and it may also damage the lawn. At the same time, non-standard operations may bring damage beyond the warranty and increase maintenance costs. For information not covered in the instruction manual, you can ask your local dealer. In addition to regular maintenance of the machine at the intervals specified in the manual, if the machine is used with high intensity during use, the frequency of use is high, and the working environment of the machine is bad, it must be checked and maintained from time to time. It is advisable to formulate the equipment maintenance plan in conjunction with the seasonal maintenance of the lawn so as to maximize the normal function of the machinery, ensure the continuity of work, and reduce the cost of machine maintenance.
