Everyone knows that sharp mower blades are key to having a well-mowed lawn, but working out how often to sharpen them can be difficult, and not sharpening your mowers blades regularly can have bad consequences for your mower and the lawn.
The schedule of sharpening your mowers blades will differ for everyone depending on the blades they buy, how often they mow and the condition of there lawn. On average, we recommend sharpening your lawnmower's blades after 25 hours of use or around twice a season to get a professional cut on your lawn.
We have gone into some further detail below about when to sharpen your mowers blades below and how to see the signs that your blade might need sharpening.
So as you can work out a specific schedule of when to sharpen your mowers blades, we recommend using the 'after 25 hours of use' rule.
To use this 25-hour indication, you first need to work out how long it takes you to mow your lawn, if it only takes you 30 minutes to mow your lawn then you would have to sharpen your blade after 50 mowing sessions to maintain the correct sharpness.
As we mentioned above, this will still depend on several factors such as the season (summer will need mowing more often), the condition/size of your lawn (such as thick grass) and what blades you are using; mulching blades will need sharpening much more often than regular ones.
Using blunt blades on your lawn can ruin the health of it and cause more strain on your mower to cut grass, you may also use more time to mow as you will have to keep going over the same patch of your lawn to get an even cut.
We have listed some other consequences below.
