I recently bought a house and have this 250 sqft backyard with really tall grass (about 7 inches). I found an 18" push reel mower and an electric trimmer (weedeater) thing in the garage. The reel mower is not able to cut anything, I guess, since the grass is really tall plus the blades looks really dull to me. So my question is: can I use the electrical trimmer to cut 1/3rd of the grass in the entire lawn a couple of times and then go back to using the reel mower when the grass gets manageable. I mean, is it OK to use the trimmer for the lawn, or are they specifically meant for edges and would destroy the lawn if used to cover the entire area?
Well a trimmer won't destroy the lawn but it won't do a good job. It is difficult to keep the trimmer head at exactly the same height.
Edit: Ok, maybe not WD40...
