Lawn trimming machine specification operating points

Pruning is one of the most basic measures in all turf maintenance management measures. The purpose is to keep the lawns tidy, beautiful and give full play to the turf function of the lawn; pruning gives turfgrass moderate stimulation to inhibit its upward growth and promote litchi and twig density. The improvement will also help to improve the air and light function of the grass layer and make the lawn grow robustly. Correctly and standardly operating the trimming machine is the fundamental guarantee for the quality of the lawn trimming, and it is also the key to improving the service life of the lawn trimming machine and reducing the maintenance cost of the green space.

1. Lawn pruning machines should be regularly inspected and strictly followed the correct operating specifications during use to avoid mechanical damage to the human body and damage to machinery caused by illegal operations, as well as some unnecessary accidents and failures. Before each use, be sure to check whether the amount of gasoline and lubricating oil is sufficient. If insufficient, add fuel in a timely manner to avoid engine scrap caused by insufficient lubricant.

2. In the process of use, it is necessary to observe the reliability of the mechanical moving parts and transmission parts, check whether the gap size is within the normal working range, and adjust in time if problems occur; check the firmness of the fasteners and loosen the fasteners. Reinforce in time; listen to the abnormal sound of the machine, confirm the cause of the disease and timely repair and maintenance. Some problems that can be solved or controlled through adjustments, lubrication, etc., must be resolved in a timely manner, and major operations such as mechanical overhaul or dismantling should be avoided as much as possible, thus affecting maintenance management and causing an unnecessary increase in maintenance costs.

3. Lawn pruning machinery must be regularly maintained during use, to achieve "three points by repair seven points by maintenance"; must be strictly in accordance with the requirements of the engine's fuel and lubricants, marking, quality and mixing ratio (two stroke Gasoline engine) to raise. For example, the B&S engine's lubricating oil should be SAE40 engine oil, and the first time the engine should be replaced after 5 hours. Change it every 50 hours after running-in. Gasoline should use No. 93 or above marked gasoline or unleaded gasoline.

4. Based on the height of the lawn and the ability of the pruning machine to determine a reasonable amount of pruning and stubble height. The pruning cycle should be as short as possible, and the amount of pruning should be as small as possible. The lawnmower should work under low load conditions; the extra long grass should be pruned in stages and follow the principle of 1/3.

5. Try to avoid mowing the lawn after irrigation, after the rain, or when the dew is relatively high. If the grass is wet, it can cause mechanical build-up and slipping, and slipping can accelerate mechanical wear.

6. The blade should be sharp, flat and the tail should be intact. The blunt blade not only affects the landscape effect of the lawn, but also provides environmental conditions for the infection of the disease. Before cutting, check whether the cutting point of the blade is at the same height. The uneven blade cannot trim the flat lawn and it will damage the machine for a long time. The intact tail can ensure that the upward air flow in the volute casing can be formed enough to make the blades upright, so that the cutting can be completed cleanly, quickly and effectively. At the same time, there is enough airflow to send the crushed grass to the collection bag.

7. The walking speed of the lawnmower should be limited to the ability of the lawnmower cutterhead to effectively cut grass and row grass, and maintain a good trimming quality range: too fast walking speed will reduce the work quality of the lawn machinery and it is also easy Damage to machinery, affecting the life of the trimming machine, can also cause safety accidents.
