Swardman blades are made from a specially modified steel which means the blades can be sharpened again and again (a process known as “grinding”) to restore a perfect cut, even on damaged cylinders.
We strongly recommend that the cylinder and bedknife blades of the Swardman mower be sharpened on professional grinding machines.
With standard sharpening, the service life of a cylinder is 10 years, assuming it is being sharpened once per year.
The rate of wear on the cylinder depends on many factors. The cutting height, the cleanliness of the lawn, intervals between user adjustments, mowing rate, and, of course, the area being mown.
