In agricultural machinery, the use of lawn mowers is relatively dangerous. If used improperly, it is very easy to cause personal injury or machine damage. Nongba.com here reminds farmers that users must pay attention to the following issues when using lawn mowers to avoid unnecessary troubles due to improper use.

1. Familiarize with the instruction manual

Before use, you should read the manual, keep in mind the safety precautions in the manual, master the installation, adjustment, operation, and maintenance methods, and understand the scope of application, supporting power, spindle speed and other technical parameters.

2. Installation and adjustment requirements

1. The lawn mower should be placed or fixed on a solid and flat foundation. The work site should be spacious and equipped with fire prevention measures.

2. Select the motor in strict accordance with the matching power and speed specified in the manual. The power cord should be made of copper conductors of no less than 6 square millimeters. The current value carried by electrical appliances such as power switches, sockets, and plugs should not be lower than the rated current of the motor (specifically, follow the motor manual). The power switch should be installed within the operator's range of activities, and generally should not be more than 3 meters away from the operator, and there should be no other obstacles in between.

3. Try to use the pulley that comes with the lawn mower. Do not change the size of the pulley at will to increase the speed of the mower.

4. Adjust the gap between each movable blade and the fixed knife. The gap should be controlled so that it can pass two pieces of printing paper and can ensure that there is no rubbing between the movable and the fixed knife. After adjustment, tighten the fastening bolts of the movable blades and fixed blades (if necessary, the method of lengthening the handle of the wrench should be used to increase the degree of tightening). After that, lock the upper case and confirm that it is firm and reliable.

5. Before the motor is installed and the belt is hung, power on for a short time, check and confirm that the rotation direction of the motor (driving wheel) is the same as the specified cutter wheel rotation (reverse operation of the mower is strictly prohibited), and then hang the belt. And adjust to make it moderately tight.

6. Install belt protection cover, grass feeding bucket and other accessories. Add an appropriate amount of lubricating oil to the gearboxes, bearings and other parts that need to be lubricated.

3. Preparation and inspection requirements before operation

Before each operation, the following preparations and inspections should be carried out in sequence. After confirming that they meet the requirements, the mowing operation can be carried out.

①Pour proper amount of lubricating oil into each oil filling hole. ②Check whether the gap between the moving and fixed knives meets the requirements. If any problems are found, they should be adjusted according to the regulations. ③Check whether there are cracks in the cutter wheel, blade, frame, etc., and replace the parts if any problems are found. ④Check whether the fasteners of the blade and other parts are tightened and deal with the problems in time. ⑤Check if the upper case is locked and secure and lock it in time if any problems are found. ⑥Turn on the power and run dry for 2 to 5 minutes, check whether the rotation direction of the lawn mower is the same as the specified direction (do not open the upper casing at this time), observe whether the whole machine is running smoothly, if there is any abnormal sound or vibration, and stop if there is any problem. Exclude afterwards. ⑦Check whether the adjustment of the shifting handle is flexible and whether the shifting is accurate and reliable. If the problem is found, stop the machine and eliminate it. ⑧ Check whether there are any hard objects such as metals and stones in the straw to be cut. If there are any hard objects, they should be removed.

Four, job requirements

1. During operation, it is strictly forbidden to remove the belt protection cover and grass feeding bucket. It is strictly forbidden to make and replace the grass feeding bucket with safety protection size less than 55 cm. It is strictly forbidden to open the upper casing.

2. People who have not mastered the safety rules of lawn mowers are not allowed to work alone.

3. It is strictly forbidden for minors and those who have been spilled, sick or overly fatigued to start operation.

4. When feeding, hold the second half of the straw with both hands and release the hands in time after sending the first half to the feeding port. It is strictly forbidden to reach into the grass-feeding mouth.

5. Control the feeding amount. The feeding amount should be even, not too much. When it is found that the speed of the lawn mower is reduced, the sound becomes louder, or the output is uneven, and the throwing distance is obviously reduced, it means that the feeding amount is too much and should be reduced in time.

6. If an abnormality occurs during operation, the power supply should be cut off immediately, and it is strictly forbidden to check and troubleshoot while the machine is running.

7. When stopping the mowing operation, keep the lawn mower running for 2 to 3 minutes to blow away the materials in the machine. After stopping, adjust the shifting handle to the "stop" position.

Five, maintenance requirements

1. The lawn mower should be stored in the warehouse as much as possible, and the outdoor storage should be protected from rain and moisture to avoid rust.

2. When replacing the moving and fixed blade fastening bolts, high-strength bolts must be used instead of ordinary fasteners.

3. The blades of moving and fixed blades should be sharp and sharpened frequently.

4. The bearings should be cleaned and greased every six months.
