To choose the best lawnmower machine, you ought to be conversant with the various types, their component, the designed height, the type of energy used in powering the machine, and their impact on the environment. Hence, this will help you make an informed decision because there are various mowers available in the marketplace nowadays.
Introduction
It is also known as a lawnmower or mower. The machine utilizes one or more reels to cut the surface of the grass to an even height. The grass's height depends on the mower's design, although the user can adjust the machine to the desired height.
It is achieved by adjusting the bolts and the master levers. The blades may be powered manually by connecting the wheels to the cutting blades; pushing the forward machine results in the blades' spinning. The source of the power of lawnmowers is a small internal combustion engine.
- a) Reel or cylinder mowers
It possesses a fixed horizontal chopping blade at the required cut height. Above this, a fast-spinning revolving blade forces the grass past the cutting section. Each blade forms a helix around the reel, which results in spinning cylindrical blades. The components of a cylindrical mower are:
- Cylinder /reel blade: has multiple helix blades attached to a rotator. The rotation of these plates creates a scissor-like chopping movement against a base knife.
- Body frame: this is the main structure of a lawnmower on which the components of the mower are mounted.
- Wheels: aids in propelling the mower while in use. Reel mowers have two wheels.
- Push handle: this is the power source in a manually operated mower. It may be rectangular, trapezoid or T-shaped moaned mounted to the frame, wheels, and blade chamber.
- Motor: is the power source in a mower that uses electricity or gasoline.
- b) Rotatory mowers
A rotatory grass cutter machine spins on a vertical axis depending on the effects of cutting the grass. This results in bruises and a rougher cut. Rotatory mowers must be designed higher than cylinders to prevent gouging and scalping of uneven lawns. The main components of a rotatory mower are;
- Cutter deck housing: enclose the blade and the driving system of a mower. Its shape is designed to eject the grass clips from the mower.
- Drive system and blade mounting: blade of the rotatory mower is connected directly to the shaft of the engine, but a hydraulic motor propels it.
- Mower blade: rotates in a horizontal plane. Some lawnmowers have numerous blades. Blades have slightly curved edges to facilitate persistent airflow during the rotation of the blades, thus resulting in tearing and sucking action.
- Engine/ motor: may be powered by electricity or gasoline.
- Wheels: Have four wheels, two at the front and the rest at the back.
- c) Classification according to an energy source
- Gasoline
A rotatory push mower generates energy from internal combustion engines, usually four-stroke. The ancient models used two-stroke engines powered by gasoline or any other liquid fuel.
- Electricity
They divide into cordless and corded electric designs. Corded mowers are limited in range by their power cord. Moreover, cordless mowers are operated by rechargeable batteries.
Conclusion
Lawn mowers are essential in grass cutting; they are various mowers, and a choice can be made depending on one's tests and preferences.
A lawn mower can result in environmental pollution due to the intensity of the noise produced during its operation. The risk of noise pollution and hearing loss can be decreased by using battery-operated mowers or wearing protective devices such as earmuffs or earplugs.
