With the development of city construction, there are increasing demands on the greening, but the traditional mowing way is always by man hand, which has low efficiency, high noise, and also has the existence of security risks. In this paper, a kind of automatic mower is designed based on the Single Chip Microcomputer, automatic mower has high efficiency, low noise, and also can avoid the staff ...

1 Description of the Model We consider an autonomous lawnmower that uses a probability bias to avoid patterns on lawns. This mower is started on a rectangular grassed area. When it reaches the border of the area, it changes its direction. To prevent the mower from following a simple cycle pattern, this direction is randomly biased, such as to ensure that finally the entire area has been cut. A ...

The design objective is to come up with a mower that is portable, durable, easy to operate and maintain. It also aims to design a selfpowered mower of electrical source; a cordless electric lawn mower. The heart of the machine is a battery-powered dc electric motor. It comprises of a system of speed multiplication pulleys which drive the cutting blades and the charging unit comprising of a 12V ...

Miscanthus is emerging as a promising feedstock for domestic biofuel production. However, inefficiencies of the machinery that is used for harvesting bioenergy crops such as miscanthus currently prohibit commercial production. The performance of a mower-conditioner used to harvest miscanthus was evaluated, and modifications to the disk head were made to allow the machine to operate more efficie...

Optimum energy consumption and prevention of energy losses are important issues in various fields including agricultural engineering. Mower is one of the agricultural machineries that can waste too much energy if does not function properly. In this study, the performance of a single disc rotary mower was studied and optimized by measurement of cutting quality of the stem cross section (cutting ...
