First, maintenance of good equipment. Long-term storage of small windrower, should be used before a comprehensive inspection, repair, according to the requirements, should be replaced on the replacement parts, such as blades, gears, belts and so on. Transmission, cutting and other parts should be flexible and reliable, the gap is normal. Repair and power assembly test. For supporting the use of small drag cooling system, suction system for maintenance. Oil and diesel for the summer brand. Second, do a good job in dust prevention, fire prevention facilities. And the windrower supporting a small tractor, in order to prevent dust when harvesting, polluting, should be raised into the trachea, generally 90 cm from the ground on the basis of an additional 1 meter high, plus the connection of the tube to be closed Tight, smooth inner diameter. Exhaust pipe to install a fire cap to ensure the safety of cut. Third, improve and install the wing board. In order to solve the problem of blockage during harvesting, the windrower wing panels should be improved. Too wide (60 mm) and too narrow (30-45 mm) are not suitable and should be changed to 50 mm. During installation, the hypotenuse and the straight edge of the wing converge
