Lawn Mowers By Michael Gubesch and Thomas Buchwald

Rotary Lawn Mowers Every rotary lawn mower needs a motor to make the blade spin fast enough to cut the blades of grass cleanly. Most rotary lawn mowers are powered by an internal combustion engine, which runs on either two cycles or four. Two-cycle motors burn a mixture of gasoline and oil, while four- cycle motors burn gasoline and have a separate lubrication system. However, rotary lawn mowers that use electric motors powered by a cord, a rechargeable battery or even solar power are also popular.

Riding Mowers Riding mowers come in different sizes and types, with different horsepower engines and blade sizes. For larger lawns, a garden tractor is a heavy- duty version of a riding mower Equipped with an 18 to 24 horsepower engine, a garden tractor can cost $9,000, but popular varieties cost $2,500 to $4,500.

Safety and Maintenance Every year, 75,000 Americans suffer injuries from mowing the lawn. Nearly 10,000 of the victims are children. Keep a clean machine. Remove debris from the engine screen after every use Use the right gas. Respect the blade. Make sure your blade is on tight

Technological Advances in Mowing Robotic lawn mowers can mow your lawn while you're sipping a cool drink on your hammock. Most robot lawn mowers run on cordless rechargeable batteries, and some are charged by solar power. Those lawn mowers could run on electricity powered by the sun, if the technology improves. Or they could run on biodiesel or hydrogen fuel cell technology already under development.
