Introduction to the basic content of lawn mower

  Lawn machines have many names, and they are also called lawn mowers, lawn mowers, lawn trimmers, and lawn mowers.

  The lawn mower is composed of cutter head, engine, walking wheel, walking mechanism, blade, armrest and control part.

  Working principle: The cutter head is installed on the walking wheel, the cutter head is equipped with an engine, and the output shaft of the engine is equipped with a blade. The blade uses the high-speed rotation of the engine to trim the lawn.

  Conditions of use:

  For lawns under 2000 square meters, you can choose hand-push lawn mowers, lawns over 2000 or 2000 square meters, and self-propelled lawn mowers. When there are many trees and obstacles on the lawn, you can choose a front wheel universal lawn mower. When the area is large, you can choose a lawn tractor. Generally, 1.07 meters (42 inches) lawn mowers are suitable for lawns of 12,000 to 15,000 square meters, and 1.17 meters (46 inches) lawn mowers are suitable for lawns below 20,000 square meters.

  Notes for use: clean up the site

  Remove rocks, branches, and various debris. Mark the nozzles and obstacles.

  Clothing: thick-soled shoes and trousers, mainly to prevent the blade from hitting rocks and hurting people.

  Site: Do not cut grass if the slope angle exceeds 15 degrees to prevent injury to people and damage to machinery. Do not cut the grass immediately after raining and watering to prevent people from slipping and machine work.

  It is especially emphasized that when the lawnmower is operating, no one is allowed within 10 meters, especially when the side row is side row, the side row mouth can not be opposite to people. Be sure to stop the machine when adjusting the machine and falling grass. Never adjust the machine or fall grass while the machine is running.

  Height adjustment: The stubble height after cutting should be determined according to the requirements of the lawn. The stubble height for warm-season lawns in the south is generally 3 cm, and the stubble height for cold-season lawns in the north is 5 cm. When cutting the grass, the cut height is one-third of the original height of the grass. When cutting the grass, it can only be cut horizontally along the slope, but not up and down along the slope. Be especially careful when turning on slopes. Beware of obstacles in caves, trenches, mounds, etc. and grass.

  The role and use of the safety handle: The safety control handle of the lawn mower is a ceasefire switch that controls the flywheel brake device and the ignition coil. Press and hold the safety control handle to release the flywheel brake device, disconnect the ceasefire switch, and the gasoline engine can start and run. On the contrary, when the safety control handle is released, the flywheel is braked, and the stop fire switch of the ignition coil is connected, and the gasoline engine stops and is braked. That is, only by pressing the safety control handle, the lawn mower can operate normally. When an emergency occurs during operation, release the safety control handle to stop the lawn mower. Therefore, never tie the safety control handle with a wire during operation.

  Maintenance of lawn mower: After each work, remove the spark plug to prevent the engine from starting automatically when cleaning the cutter head and rotating the blade.

  Check the blades: The blades of lawn mowers must be sharpened frequently to keep them sharp, so that the trimmed lawn can be level and good-looking, the cut grass has small wounds, and the lawn is not easy to get sick. On the contrary, not only is it bad for the mowed lawn, the resistance to the drive shaft of the lawn mower is increased, which increases the load of the lawn mower, reduces the work efficiency, increases the operating temperature, and increases the wear of the machine. Therefore, it is necessary to keep the blade sharp and improve Work efficiency and ensure the normal operation of lawn mowers. At the same time, you should always check whether the lawn mower blade is balanced. If the blade is not balanced, it will cause machine vibration and easily damage the lawn mower components.
