Currently, manually handled devices work on non-renewable sources of energy. Solar grass cutter focuses on the use of a renewable source of energy which will help to reduce the emission of harmful gases which are emitted by the conventional grass cutter. Solar grass cutter requires low maintenance and less human interface as compared to conventional grass cutter. Recently we are facing problems like air pollution, noise pollution, power cut problems, etc. To overcome these problems conventional grasscutter can be replaced by a Solar grass cutter which is environmentally friendly. In the market there are lots of grass cutters are available but at a higher cost, which is mostly unaffordable for farmers, but this machine is very cost-effective and affordable. Power consumption in this machine is less as compared to conventional grass cutters. In this project, two blades are used to cover more area for grass cutting. The main target of the machine is to reduce human efforts.
There is a lot of progress work has been pending but there is still some labor-power which requires lots of income allocation for a small work. So, this is required that some exertion should have some other substitute so that the labor power surplus can be avoided. So, in our project we are trying to make a daily purpose machine which is capable to cut the grasses in farms and lawns. The project work will be done according to the appropriate application-based production. The system will have a power source that is battery as well as solar panel will be attached on the top of the machine. Nowadays IC engine based traditional manual grass cutters are used. Over the field traditional grass cutting machine can create pollution and causes loss of energy. Solar power which is available naturally will be used to provide the force to drive the cutter. Usually for adjusting the height of grass cutter according to lawns & farms, it requires two types of grass cutting machines, to avoid this use of two respective machines this individual machine has been designed with ability to adjust the height of blades according to its use on lawns/farms.
Also, this machine has two blades to cover more area by which work will be done in less time with less effort. This project’s main objective is of fabricating a grass cutting machine system that makes use of solar energy which is available without any cost. As there is a continuous increase in the cost of fuel and the effect of emission of gases from the burnt fuel in the atmosphere, we decided to make an environmentally friendly grass cutting system which uses solar energy as well as Safety is the major priority while designing the grass cutter.

E. Solar Grass Cutter Machine
Sachin Prabha et. al. The writer fabricated a solar grass cutter machine for reducing human work and also consuming non-renewable sources of energy on the earth’s surface. By using solar panels the energy is acquired from the sun and stored in batteries and uses this energy as per the requirement. All these functions are proceeding according to prescribed time by proper monitoring. A specific mechanism provides for the protection of batteries from extra charging which increases the life span of batteries. It can also be used on small scale for gardening.
F. Smart Solar Grass Cutter Robot for Grass Trimming
Ashish Kumar Chaudhari et. al. In this paper author explained that the solar plate which is placed above the grass cutter generates solar energy and uses this energy for working the grass cutter. Also, using a driver circuit for controlling the speed of the motor as per the requirement. Solar panels, batteries, DC motor, solar charger, circuitry, and blades these components are used for preparing grass cutter.
For preventing the battery from overcharging and the over-discharging regulator is placed into the system and it should be placed in series. They have provided an LCD display unit that displays voltage generated during solar ray trapping. Due to seasonal conditions if the battery is not charged they can provide the power bank to charge the battery instantly.
G. Solar Based Grass Cutter : A Review
Ms. Bhagyashri R. Patil et. al. In this paper author explained that For human enlargement in many countries there is study and trials are going on the Solar energy and the wind energy, So they make there new concept solar powered grass cutting machine in these concept they cut grass s on the agricultural products or on small plants in lawns and gardens. Remote controlled grass cutter can be described as the application of Radio frequency to power a machine on which electric motor rotates which in turn rotates a blade which does the mowing of a grass. 
H. Sensor Based Multipurpose Agricultural Cutter
Prof. J.P. Wagh, Aishwarya Chaudhari et. al. in the paper titled " Sensor Based Multipurpose Agricultural Cutter "author states that, the rotary mower can rotate about a vertical axis with the blade spinning at high speed and this tends to result in a rougher cut and shreds the grass leaf easily.
