Cordless lawn mowers vary in what way from regular lawn mowers?
Cordless lawn mowers rely on an electric starter in order to start the engine. This contrasts with regular pull start motors which require the user to pull/spin the crankshaft and start the engine.
Get Reel for Less Environmental Impact?
The lawn needs cutting again. Using a reel or cylinder mower can make this chore enjoyable once again. The choices in reel mowers have greatly improved over the last several years as manufacturers respond to consumers’ desires to use less oil and create less pollution. Models now include precision height controls, ergonomic designs, and padded handles. In many ways, unless the lawn to be cut is very large, reel mowers are a real alternative for the homeowner today. Reel mowers have a long history that, for several decades, was eclipsed by the rotary power mower. But today, reel mowers seem to be machines that are exactly right for the times. These machines are people powered and have no need of gasoline. Consequently, they do not spew engine exhaust into the atmosphere, making them environmentally friendly. And they have become technologically advanced and rival or beat the cut available from rotary power mowers. Plus, the reel mower allows the user to get open-air exercise from mowing the lawn. A reel mower is simple in comparison to a rotary mower. All of its parts are readily visible for inspection. The primary cutting surfaces are the edges of helical shaped blades, which spin in the form of a cylinder. These blades slide by a cutting bar and shear the grass off. A reel mower is said to snip the grass instead of tearing it as the rotary power mower is said to do. Inspection of lawns cut by rotary mowers often reveals rough-cut edges on the grass blades. Reel mowers also need little adjustment to remain in perfect cutting condition. Blades often have long life guarantees. When sharpening is eventually needed, it is best accomplished by back lapping the blades using a sharpening compound until the blade edges are shiny. This is a procedure that an average homeowner can easily accomplish on his own, as it is straightforward and entails no special tools. Reel mowers can be used on any size lawn that rotary push mowers are used on. They take a little bit more energy to push, but this uses calories that can either replace or augment those burned at the gym.
How do helecopter blades spin so fast?
Helicopter blades operate from a transmission or gearbox immediately under the blades. They have to spin fast to give the helicopter lift. Once they are in the air the blades twist slightly to give forward motion.
Why do wind mills have blades?

Why does my Riding Lawn mower blade spin when it is started and the lever is not engaged?
If you have the correct belt on the mower, then the problem is probably the fact that your deck pulleys are not hitting the brakes that are supposed to stop them from spinning.
When a riding lawn mower squeaks and stops when you put the blade down what is wrong?
Sounds like the pulley that spins the blade is stuck. When the blade is lowered, the belt tightens on the pulley and spins it. If the pulley is stuck, it will not spin and the belt will "squeal" as it tries to spin it. The extra load that is added to the engine when the belt is trying to spin the stuck pulley is a bigger load than the engine can handle, so the engine stalls (stops). Check the blade pulley - or it is possible there may be some debris under the deck that is preventing the blades from turning.
