A lawn mower is a significant investment for the gardener. In order to choose well, the criteria to be taken into account are multiple: cutting surface, cutting width, type of motor, type of traction.
The choice of a lawn mower depends mainly on the surface to be mowed. Best zero turn lawn mower or Electric mower? For small areas, a simple, economical and environmentally friendly lawnmower will suffice if the mowing is carried out regularly. But when mowing is more occasional (as in the case of a second home for example) or the surface is large, it is necessary to turn to more sophisticated models. Among these models, the choice is very broad.
Generally, for small single-piece surfaces without borders to bypass, the best choice is an electric lawnmower. Simple to use, this type of machine requires less maintenance.
For larger areas (more than 500 m2) or for isolated grounds not having easy access to an electrical outlet, the choice must be made for a lawnmower with a thermal engine. The advantage of this type of equipment is obviously the autonomy, no wire does not thwart the maneuvers. On the negative side, the lawnmower is noisier and requires regular maintenance as well as some precautions during wintering.
Among the thermal mowers, many models are available. The differences are mainly due to the power of the engine, the cutting width, but also the traction mode. Depending on the shape of the ground and the presence of a parterre to bypass, the choice should instead turn to a lawn mower carried for lawns strewn with obstacles and towed for large rectilinear surfaces.
For surfaces between 1000 and 2000 m2, the best choice is undoubtedly a self-towed lawnmower. Beyond 2000 m2, it is more prudent to opt for a self-reaching mower limiting efforts.
In all cases, to avoid manipulation, it is advisable to opt for a model proposing a basket of pickup of cut grass. In addition to the models described above, the solution of a solar-powered robot robot is also to be studied in the case where the surface is sufficiently flat and unobstructed.
Did you know ?
Models with electric or thermal air cushions are generally more manageable especially when the terrain is on a slope. In return for the gain of maneuverability, this type of mower can not receive a container of pickup of the cut grass.
There are different types of motorization for the lawn mower:
• The manual mower;
• The thermal mower;
• Electric mower;
• And the lawnmower battery.
Before buying, it is important to know the characteristics of each type of motorization in order to choose the one that will be the most adapted to the surface to be mowed and the disposition of your ground.
The thermal mower for easy and fast mowing
The thermal mower is self-contained by taking with it its fuel tank. The gasoline engine that the team can be of modest size to large for a growing power. It is the most widespread and noisiest motor, so its use is regulated.
Mooing the lawn
In the thermal mower, a gasoline engine is used to drive the blade and possibly to propel the machine (self-propelled mower – lawnmower).
It is always a 4-stroke engine similar to a car.
The thermal engine runs on super unleaded and also requires oil in a crankcase for its lubrication. It can be single-cylinder or twin-cylinder for large power (over 15 HP) cooled by air.
The cylinder capacity of the engine will depend on the power demanded directly imposed by the crankcase width of the machine.
Thermal mower: power consumption and displacement
The fuel consumption will be directly related to its cylinder capacity:
For a powerful mower, the displacement varies from 130 cm3 to 170 cm3 for a power of 3,5 HP (2,6 kW) to 5 HP (4 Kw) in relation to the crankcase width from 40 cm to 50 cm approximately.
For a self-propelled mower, the displacement shall be at least 150 cm3 up to 190 cm3 for a minimum power of 4 CV (3.3 kW) to 6 CV (4.5 kW) depending on the slope of the terrain and in relation to The crankcase width from 40 cm to 55 cm approx.
A riding lawnmower capable of working permanently on land with slopes will have a displacement of 300 cm3 to 650 cm3 for a power of 9 CV (6.8 kW) up to 17 CV! The crankcase width varies from 65 cm to more than 110 cm.
Choose a modern OHV (overhead valve) or OHC (overhead camshaft) engine that performs better than rustic side valve motors.
If you are hesitant to take the electrical start option, remember that it will require a battery to be charged and replaced.
Advantages and disadvantages of the thermal mower
Proven, easy to operate
• Powerful (high torque)
• Reliability and robustness
• Noisy and very polluting
Consumption / cost of maintenance
• Fuel Consumption
• Regular maintenance
• Cylinder equivalent to a motorcycle for a slightly lower fuel consumption, but pollution far superior to that of a car!
• Annual maintenance from 80 € to 300 € per year (candle, filters, oil, belt).
