It is officially the mowing season in SE Iowa, and Cyclismow is on the job.  Here is the simple yet powerful set up of bicycle, trailer, and reel mower.  Freshly sharpened reel blades offer a superior cut to grass, which makes for a healthier lawn.  From wikipedia: Of all the mowers, a properly adjusted reel mower makes the cleanest cut of the grass, and this allows the grass to heal more quickly.

More importantly, the larger benefit is in environmental impact.  Research has shown over and over the advantages of human powered lawn equipment:

According to the U.S. Environmental Protection Agency (EPA), a traditional gas powered lawn mower produces as much air pollution as 43 new cars each being driven 12,000 miles.

Go human power!
