Brill also offers a blade replacement program through the US importer. There are a few challenges to using a reel mower. Reel mowers are not designed to cut tall weeds. They will simply roll over them without cutting. They are also not ideal if you let your grass grow for several weeks without cutting, because they can become difficult to push through overgrown grass.
Sticks can also stop the blade from turning, so picking up debris first is recommended.
For the health of your lawn, we recommend leaving the clippings on the lawn. They usually disappear in a day or two. However, if you're very picky about how your lawn looks, or you collect the clippings for composting, a grasscatcher is a good idea. Composting is the single best way of improving the health or your lawn and garden. Artificial chemical fertilizer is a short term solution that is not particularly good for the groundwater or environment.
