Sharpening new mower blades is important for optimal performance and a neat cut. Here are five steps to decide when to sharpen:

  1. Check the Blades: Inspect the edges for dullness/damage. Look out for nicks, dents or a rounded edge – these can show that sharpening is needed.

Remember, these are for new blades too! They may start off sharp, but can get dull from time and usage. Regular inspection and sharpening keeps the lawn looking good and promotes healthy grass growth.
