Lawn cleaner

A lawn cleaner or mower is a device that by means of one or more revolving blades is used to cut grass or other plants to an even length and cleans the lawn. Two cutting mechanisms are in common use they are reel or cylinder mowers or cleaners those with a set of spiral-cylindrical blades spinning on a horizontal axis. Cutting is by a scissor like action between the moving spiral blades and a single stationary horizontal blade or a bed knife. The axle is attached to a gear that is then mounted on one of the wheels in order to spin the blades rapidly for good grass cutting action even when the cleaner is moving slowly. Rotary mowers or cleaners are those whose blades spin horizontally on a vertical drive shaft. Cutting is due to a horizontal blade striking the grass at a high speed.

Cutting technique to clean lawn

There are main two cutting mechanisms that can lead to different results. On rotary mowers or cleaners, the blade is usually not sharp enough to cut the grass cleanly. The speed of the blade tears the grass resulting in ragged tips. By contrast, the cylinder-type reel lawn mowers or cleaners and manual lawn cleaners usually work by scissor action on the blades and a cleaner cut is achieved. Reel lawn mowers and cleaners often allow the height of the lawn mower to be adjusted to control the height of the cut grass. On older or less expensive lawn mowers and cleaners, this is accomplished by manually moving each wheel to a different slot on the chassis. A more recent innovation in rotary mowers and cleaner is a one touch height-adjust mechanism where the blades are mounted on a frame separate from the rest of the lawn mower and the frame can be raised and lowered.

Mechanism for lawn mowers and cleaners

Lawn mowers and cleaners need power for two purposes. They are to cut and to move. The act of pushing or pulling a reel mower provides power for cutting and moving at the same time. For rotary mowers, the power sources may vary. Wheel-driven gear systems allow for cutting to be powered by the same external source as that used to propel the mower and cleaners.
