A perfectly maintained lawn mower works with sharp blades, which are essential for a velvety smooth lawn. Therefore, in the spring, subject the lawnmower blade to a check to see whether it is blunt and whether it makes sense to change it. These instructions explain step by step how the exchange works.

The lawnmower blade should be changed carefully

How often should lawnmower blades be changed?

There is no hard and fast schedule for replacing lawnmower blades. The intervals at which the knives are to be changed depend on various factors. The degree of stress is just as important as the maintenance effort or the quality of the winter quarters. If a commercial lawn care provider replaces the cutter bar every 4 months, this may only make sense for a private lawn owner every 1 to 2 years.

When it comes to this question, act according to the rule of thumb: change a blunt lawn mower blade before the first lawn cut in spring. This premise applies equally to electric, cordless and petrol lawnmowers.

Material, tools and preparatory work

Safety is the top priority when changing a lawn mower blade. When purchasing, make sure that the new cutter bar is suitable for your model. If the blade and lawnmower do not match, significant damage is inevitable. You will also need a wrench and work gloves. This is how you prepare to replace the blade professionally:

  • Electric mower: Pull the power plug
  • Cordless mower: Remove batteries
  • Gasoline mower: Pull out the spark plug cable, close the fuel tap and tilt up with the carburetor

It's a good idea to have a helping hand to hold the mower steady when you loosen the bolts and change the blade.

How to replace lawnmower blades correctly - instructions

Once you have taken all the safety precautions, you can devote yourself entirely to changing the lawn mower blade. How to proceed professionally:

  • Fix the cutter bar with one hand or a piece of wood or a knife block
  • With the other hand, loosen the screw with the washer and set it aside within easy reach
  • Pull out the knife with a slight turning movement and put it down at a safe distance
  • Lay the new knife bar flush on the screw opening and hold it

Finally, screw in the screw together with the washer and tighten well. Please hold the knife with one hand while turning the wrench with the other hand.

After replacing the blade, place the lawn mower back on its wheels. On the petrol mower, place the plug on the spark plug and open the fuel tap. Insert the accumulator in the cordless mower.
