Abstract - This paper summarizes and reviews different
technological developments for making efficient and cost effective lawn mowers. A lawn mower is a device which is used to mow/ cut i.e. cut the grass of a lawn to an even height. It can be operated manually or by some energy conversions such as solar power battery power etc. Generally these are powered by electric motor or internal combustion engine and dc motors. In this paper, effort has been made to modify the old mower to improve its usability. The overall geometry is made smaller and lighter. Adjustable cutting motor height is introduced for better mowing of grass at intricate locations.
[2]. The lawn mower considered for study in this paper was quite large, heavy, is AC powered and is hand propelled. There is a need felt to make it smaller, lighter and DC powered for better handling and endurance. An effort has been made in this paper to implement the same.

1.INTRODUCTION Lawn mower is a machine that is used to cut grass. The blades of the lawn mower are powered by pushing the mower forward. The blades may also be rotated by an electric motor or an Internal Combustion engine. Lawn mowers are classified based on different criteria. For example, according to the axis of rotation of blades we may have reel lawn mowers in which the axis is horizontal and rotary lawn mowers in which the axis is vertical. The reel (cylindrical) lawn mower is found to be better. Made of blades on a revolving cylinder, they achieve clean cut by scissors action. As the mower moves forward, the rotating blades come in contact with a stationary bar called the bed knife and placed parallel to the ground. The mower is adjusted to various cutting heights. Rotary mowers are often powered either by an internal combustion engines or an electric motor and are generally mowed manually, with the engine only spinning the cutting blades. Rotary mowers are generally have opening by the side of the housing through which cut grasses are expelled. Several types of mowers exist, each suited for to a particular purpose. From 2012 onwards, there is shifting trend, about 15 times form traditional hand guided or ride-on mowers to automatic electric mowers. Since 1830, there have been various lawn mower designs that have been created. These designs include push lawn mowers, which are suitable for smaller lawns, and the ride-on mowers, which are capable to cut grass in larger lawns [1]. Other more recent models of the lawn mower contain corded and cordless electric power. Cordless electric powered lawn mowers are powered by 12 volt rechargeable batteries. Cordless mowers have the maneuverability of a gasoline powered mower and the environmental friendliness of a corded electric lawn mower Š 2017, IRJET
