The small-sized harvester is small in size, light in weight, and easy to use. Its supporting power is small [usually 8.8 to 11 kW (12 to 15 hp)] suitable for small plots, self-employed or joint ventures, and attention should be paid in use and maintenance. The following points: Before harvesting, first combine the power transmission with the machine, make it empty for a few minutes, and observe whether there is any abnormality. 2. After the tractor lands on the ground, it must start steadily and drive straight. When it is received, it is not necessary to turn off the table to avoid missing cuts. 3. When harvesting fallen crops, wheat is generally better harvested in reverse. If harvesting is difficult, one-way counter-falling harvesting or harvesting perpendicular to the lodging direction can be used. For rice, harvesting can be done with one-way falling down or perpendicular to the lodging direction. 4. When the harvester malfunctions or the crop is clogged, check it after stopping and extinguishing the fire. It is forbidden to use the parts on the harvester or troubleshoot without stopping to stop the flame so as to avoid human-machine accidents. 5. When received, the tractor's walking speed is appropriately selected depending on the height and density of the crop. 'The general crops are growing well and densely, and the speed should be slow to prevent the harvesters from being blocked; the poorly growing crops can be faster. 6. When the harvester turns, it is necessary to wait until all crops that have been cut are exported and then reduce the slow turning of the throttle. 7. After reeling for 2 hours, the bearings should be lubricated. After 10 hours of operation, all lubrication parts should be lubricated. 8. In the harvesting process, attention should be paid to observing the field conditions. If there are bricks, stones or other hard objects, they should stop immediately and move them away to avoid damaging the cutter. 9. After each operation of the harvester, the header shall be landed on the ground to remove the dust, the Burmese grass, and the mud between the knife and the press, and add the oil. 10. The reeling wheels of small-sized harvesters are mostly made of hard plastic. If they are deformed or broken, they can be repaired by hot-calendering and adhesives. Blasting This is the twisted deformation of the wheel point, placed in the boiling water to soak or bake on the fire until the turn point becomes soft, the wheel point pad cares on the board, and then add on the wheel point - flat pressed hard to restore As it is. Adhesive method is to first break the hair, and then the breakpoint with 60-type adhesive glue, according to the original fracture alignment, tight, 24 hours after use. 11. At the end of the harvest season, the harvester is fully serviced and repaired once. Wash and remove the parts of the machine and inspect the parts for damage or deformation. Check whether the lubrication of each lubrication area is adequate. Apply anti-rust oil to the cutting and stripping parts. Finally, store the whole unit in a ventilated and dry place for use in the next year.
