Each lawn owner faces a difficult task – how to choose a lawn mower. In warm seasons it is most often necessary to mow the grass, but it is difficult, slow and unsafe to do it by hand. The process can be greatly simplified if you buy a lawn mower.
All you have to do is choose the right model
Lawn mowers differ in the design of the cutting system, there are different power levels. Non-self-propelled lawnmowers need to be pushed in front of you, self-propelled mowers move with a motor and robotic mowers mow the grass without human assistance.
Which model is better – gasoline or electric
How to choose a lawn mower and which is the best? A lawn mower with a gasoline engine is bought to work on sites with more than ten hectares. The disadvantages of such lawn mowers: they are noisy, they need gasoline, oil and spark plugs. The gasoline model with a manual starter is difficult to start – you have to pull the cable with force. Electrostarter models start with a button, but they cost more.
A significant disadvantage is a gasoline lawn mower is unecological, because it emits exhaust fumes into the environment.
Lawn mowers with an electric motor are used on small lawns in front of cottages and on country houses from two to ten hectares. Electric lawn mowers do not emit smoke, are less noisy, cost cheaper than petrol mowers and are much easier to use.
They only operate from a power source, so the area of possible coverage is limited. This problem can be solved with an extension cord. However, you need to make sure that the power cord does not get under the blades of your lawn mower. Also, they should not be switched on in damp weather or in the mornings when there is a lot of dew .
Battery mowers are more mobile. They run for two to ten hours without recharging.
What’s the difference between a non-self-propelled lawn mower and a self-propelled one?
How to choose a lawn mower and what’s the difference between a non-self-propelled lawn mower and a self-propelled one? Self-propelled lawn mowers need to be pushed in front of you. Usually these are lightweight, compact and low-power models. They are suitable for small areas of five to eight hectares. They need to be pushed manually, which is quite inconvenient. But it is easier to drive around obstacles – you don’t have to stop the engine.
Self-propelled equipment weighs much more and is equipped with a powerful motor, which drives knives and wheels. All you have to do is guide the machine. Sometimes in self-propelled models there is a function to switch off the knives without stopping the engine. This is necessary when working in areas with difficult terrain, such as when you have to cross paths made of gravel. The main disadvantage of self-propelled models is the higher cost compared to non-self-propelled models. On the other hand, you can mow grass on lawns up to 20-30 hectares.
Self-propelled lawnmowers are divided into front-drive, rear-drive and all-wheel drive mowers. Professionals recommend buying a rear-wheel drive model, as the main load here falls on the rear of the device.
Landscaping professionals recommend the use of non-self-propelled lawnmowers because they handle young grass more gently. If you have problems with your spine, it is best not to buy a lawn mower like this – you will quickly get tired.
What are the features of robotic lawn mowers
Programmable robot lawn mowers work without human intervention. The lawn must be prepared beforehand for the robot: it must be free of debris, bumps, stones and other obstacles. The grass must not be too high. In addition to a powerful battery, the automated lawnmower also includes special sensors that help it to detect lawn borders and bypass obstacles.
Some robotic lawnmowers have a built-in GPS navigator – they can be used to trace any trajectory. Non-navigated models follow the route according to their memory diagrams.
To recharge, the robot returns to the base on its own.So that the lawn mower is not stolen when it is operating unattended, it is equipped with an “anti-theft system”. Advanced models transmit their GPS coordinates to the owner and send messages if the device is stolen.
Some devices come with a special remote control that allows you to control the unit. The manufacturer has already laid down the basic program, and with the remote control you can include additional parameters and set new working conditions.
The model also has a built-in rain sensor, which protects the device from breakage. The robot will not work in bad weather or in high humidity. Robots are not afraid of light rain, but they stop working and return to the base if heavy rain or auto watering is activated.
What are drum mowers?
How to choose a lawn mower? Inside the drum mower is a drum on which the blades are spirally fixed, another blade is fixed motionless. When the mower works, the drum rotates and its blades cut the grass like scissors.
These lawn mowers don’t have a motor. So they work quietly and mow very cleanly, but are only suitable for well-groomed lawns and areas where grass is mown all the time. Technicians can’t cope with running lawns – thickets must first be trimmed.
How do rotary lawnmowers work?
The rotary lawn mower has a motor with a shaft on which the blades rotate very quickly parallel to the ground.
Most household models have knives with two blades, and there are also four-blade blades, which cut much cleaner. Knives become dull over time, and they need to be sharpened periodically.
With a rotary lawn mower, you can mow hard grass and work in rough terrain and small hills.
What does the drive have to do with it?
Front-driven lawn mowers have front wheels that rotate. These models are manoeuvrable and easy to operate, but they are only used on flat ground.
The rear-wheel drive mowers are designed for heavy work. If the rear wheels are larger than the front ones, the rear-driven lawn mower can be used on slopes and uneven ground.
All-wheel drive vehicles can work on any surface, even on hilly and slippery ground.
What kind of power is optimal?
Typically, the motor power of a lawn mower is 0.8-3 kW. The higher the power rating, the higher the performance. However, if the area is small and you clean it regularly, do not use a lawn mower with an overly powerful motor. It will consume an unreasonably large amount of electricity.
A powerful lawn mower does the job faster and has a wider mowing width. For example, the 1600-1800 W model handles a 45 cm wide swath in one pass, and it takes no more than six minutes to clear 100 square metres of grass. The less powerful 1000-1200 W models have a working width of no more than 30 cm and will take twice as long to clear the same area.
To mow a 300 square metre lawn with a 30 cm wide lawn mower, you have to walk more than a kilometre, and with a 45 cm wide lawn, you have to walk one and a half times less.
In order to select the power, you must proceed from the area of the lawn:
- – up to 400 square metres – electric up to 1000 W, petrol up to 3 HP..;
- – up to 1200 sq. m. – electric up to 2000 W, gasoline up to 5 hp;
- – over 2000 sq. m. – gasoline over 5 hp.
How high can a lawn mower mow the grass?
If you have the cutting height adjustment function, you can achieve an even grass height throughout the work area. For healthy grass growth, you must cut no more than one-third of its height at a time.
Most lawnmowers mow grass between 20 and 30 mm high. Powerful models can handle grass heights of 60-80 mm.
The height adjustment can be manual or mechanical. In the first case, you have to stop the engine, rearrange the wheels yourself and switch the wheel axles. In the mechanical version, simply press the central control lever once to change the height of the cutting mechanism.
Where to put the cuttings
Lawn mowers throw the cuttings aside or collect them in a grass catcher box. The standard mode for all mowers is to throw the grass back or to the side. This is usually done when high grass has to be mown quickly.
A grass catcher box is a plastic, fabric or mesh bag where grass is collected after mowing. Most lawnmowers have it in their pockets, but you can also buy it. The standard volume of the grass catcher box is 65 litres.
Lawnmowers with mulching function finely chop the grass and throw it on the lawn. The shredded grass is used as fertiliser. Mulching is used if the grass is not high and the lawn needs fertilisation. Many rotary lawnmowers and all robotic lawnmowers have this function.
What you have to remember
- Lawn mowers with gasoline engines are more noisy and environmentally friendly. They are bought for plots with more than ten hectares. Models with an electric motor are used on small lawns. Such mowers work only from a power source, they make less noise, cost cheaper than gasoline mowers and are much easier to use.
- Non self-propelled lawn mowers need to be pushed in front of you. Self-propelled machines weigh much more and are equipped with a powerful motor that drives knives and wheels.
- Robotic lawnmowers work without human intervention, but the lawn needs to be prepared beforehand. You can lay out any trajectory of movement or operate it from the remote control.
- The drum mowers work quietly and mow very cleanly, but are suitable only for well-groomed lawns and areas. Rotary lawnmowers can mow hard grass and work in rough lawns and small hills.
