After firing my landscaper over myriad issues, I decided to start cutting my lawn myself again. I have a gas-powered mower which works fine, but I was thinking about buying a reel mower. Supposedly the technology is much improved over the older models (which seemed to just mash the lawn down). Benefits would include getting a much better workout, no fumes, and the ability to cut the lawn during parts of the day that I can't with a powered motor (due to the noise). They also say the lawn is healthier being "scissor-cut" with a reel mower than with a rotary blade that tears the grass. My concern is that the cutting swath is only 15" on the particular model I'm looking at (Brill Lux 38). Will it take me forever to cut my 1/3-acre lawn? My lawn is very flat, so at least I won't have to go over a bunch of inclines. Any experience with this type of mower would be appreciated!
