This week is to study about lawn mower for this project. What is lawn mower?
MOWER TYPES:
TRIMMER-TYPE MOWING SYSTEM
The trimmer-type mowing system presented in this work has a fixed edge and a moving edge. There are two advantages of using a trimmer-type mowing system.
If a cutter edge comes into contact with people, it can cause serious injury. In the event of the proposed arrangement, the fixed edge of the trimmer extends beyond the striking boundary. Hence, the fixed edge is the first to reach any object in the way of the system. This boundary is designed so that masses can be safe even after a collision. In addition, when the system is mowing close to an obstacle such as a wall, the trimmer does not damage the wall as a rotary cutter would. Further, the proposed trimmer does not call for a hood, unlike a circular cutting tool. Therefore, the cutting edge of the trimmer-type mowing system can reach right up to a wall. The proposed trimmer also has the advantage that it does not cause stones to be expelled as easily as in the instance of a rotary cutter.
Rotary mowers
Rotary lawn mowers have one very high speed rotating blade underneath. The blade ‘chops’ the grass on impact due to its very high speed. Most rotary mowers have the grass box behind with a few having an integral grass box. These mowers work best on a medium to high cut. A Rotary Mower is a mower in which the blade spins horizontally (east to west) and uses a sucking and tearing action to cut the blades of grass. Rotary mowers usually have one blade which rotates very fast. The rotary mower design is simple and adapts very well to small engines. Rotary mowers can cut a wide variety of grass conditions. Rotary mowers are usually powered by gas engines or electric engines.
