What is torque?
Torque is a measure of the rotational force of an object. When tightening the lawn mower blade, the torque acts to securely attach the blade to the mower shaft. The correct torque ensures a stable connection between the blade and the mower shaft so that the blade does not wobble or become loose during mowing.
Why is the correct torque important?
An incorrectly set torque can cause a number of problems. If the torque is too low, the blade may come loose during operation, resulting in unclean cuts and possible damage to the mower or mowing shaft. On the other hand, if the torque is too high, there is a risk of damaging the thread or overloading other parts of the mower.
Tips for setting the correct torque
Look in the manual
Each lawn mower manufacturer provides recommendations for proper torque in the owner's manual. It is important to read and follow this information to ensure you are tightening the blade to the manufacturer's specifications.
Use the right tool
Use a torque wrench or suitable tool to tighten the blade. This will allow you to set the torque precisely and ensure that it meets the recommended values.
Even tightening
Be sure to distribute the torque evenly by tightening the bolts or nuts in a diagonal sequence. This will secure the blade evenly to the mower shaft and ensure a stable connection.
Periodic review
Check the torque of the lawn mower blade regularly, especially after replacing the blade or when servicing the lawn mower. This will ensure that the blade is always properly secured and that optimum cutting performance is achieved.
Frequently asked questions about torque when changing lawn mower blades
To tighten the blade screw with the correct torque you need a Wrench or a torque wrench that indicates the exact torque.
Yes, it is advisable to check the torque, especially after the first few minutes of mowing. This will ensure that the bolt is properly tightened and has not come loose.
Too little torque can be characterized by loose connections, vibrations, and unusual noises during operation, as well as the occurrence of loosening or failure of components. Excessive torque can lead to damaged threads, cracks in the components, or even breakage of fasteners. Signs of this include excessive resistance when tightening bolts or nuts, deformation at the connection points, and the breakage of components.
It is important to use the correct screw for changing lawn mower blades to avoid damaging the machine. Make sure the blade is in a vice when changing it to avoid damaging it. Use a high-quality screw that is suitable for the purpose. Tighten the screw to the recommended torque to ensure safety.
A lawn mower blade should be sharpened regularly to ensure optimum performance. Make sure to sharpen the blade as soon as the cutting performance decreases or the grass blades are no longer cut cleanly. Unclean cutting edges can cause damage to the lawn, so we recommend sharpening the blade in good time.
To visually check if the lawn mower blade is balanced, you can look for any grooves or bumps on the blades and any signs of material fatigue. You should also look for any damage to the blades, as this can lead to imbalance.
