When the lawnmower makes a loud rattling noise, it gets on the nerves of the operator and the neighborhood. If the noise level suddenly increases when mowing the lawn, you can solve the problem with a simple measure. Find out how here.
If the lawn mower blade is battered, the lawn mower will make noise
Battered blades make the lawnmower loud
Hitting a rock is enough to seriously damage a lawnmower blade. As a result, the device vibrates and emits unmistakable rattling noises. In combination with the already loud petrol engine, the noise pollution takes on unimagined dimensions. To make your lawn mower work quieter again, you should replace the broken blade.
New blade makes the lawn mower quieter - how to replace it
To replace the chipped cutter bar, all you need is a new, type-specific example, new screws with washers and a wrench. Before you start the actual assembly work, please pull the plug from the spark plug and turn off the fuel cock. How to change a lawnmower blade professionally:
- Tilt the lawn mower to one side so that the spark plug and air filter are facing up
- Block the cutter bar with a piece of wood
- Stabilize the knife with one hand to loosen the screws with the other hand
- Pull off the old cutter bar with the help of slight turning movements
Please note that some lawnmower models have left-hand thread screws at this point. Place the new lawnmower blade precisely on the screw opening and screw in the screws and washers. For safety reasons, we recommend a torque wrench for this work so that you can screw in the screws precisely according to the manufacturer's instructions.
With the new cutter bar in place, tip the mower back onto its wheels. Place the spark plug connector on the spark plug and turn on the fuel tap. The next time you cut the lawn, your lawn mower will run as quietly as it did on the first day.
tips
It is in the nature of things that petrol lawn mowers work much more noisily than electric mowers. If you basically have a problem with the loud engine, we recommend switching to another type of lawnmower that promises whisper-quiet work.
