Min. cutting height
The minimum cutting height provided by the lawnmower — that is, the smallest height of grass that can remain after the passage of the machine. It makes sense to pay attention to this indicator mainly in cases where the lawn is planned to be cut as short as possible. In addition, the lower the minimum height (with the same maximum), the wider the height adjustment range of this model.
Recommended area
The area of the site for which the lawn mower is designed. It cannot be argued that this parameter is critical when choosing a device, these are only manufacturer's recommendations and are very conditional. However, they are more than justified and generally show the available front of work based on the heating of the motor, the capacity of the tank or battery, and other factors that affect the duration of work.
Bag volume
The volume of the grass clipping bag supplied with the lawn mower. Manufacturers select this volume depending on the power, performance and overall level of the unit, however, similar models may differ in this indicator. In such cases, it is worth considering that a larger bag takes longer to fill and needs to be unloaded less often, but it weighs more and takes up more space (even when empty). Mostly the difference in the volume of the bag is 5 liters and there are
lawn mowers for 35,
40,
45,
50, 55,
60,
65,
70 and more liters.
Brushless motor
The presence of a brushless (brushless) motor in the device. Such electric motors have a number of advantages over traditional collector motors: in particular, they are more economical in terms of energy consumption, less noisy, and also do not spark. The disadvantages
of brushless motors are complexity and high cost.
Front wheel diameter
The diameter of the front wheels of the unit. For more information about this parameter, see "Rear wheel diameter" — everything written there is true in this case. We only note that the front wheels relatively rarely have their own drive, so the diameter for them is not as important as for the rear ones.
Rear wheel diameter
The diameter of the rear wheels of the unit.
Larger wheels, on the one hand, increase cross-country ability and allow you to effectively overcome pits, bumps and other obstacles on rough terrain. On the other hand, they cost more, are more expensive, and in self-propelled models, they also require more traction from the engine.
This indicator is often determined by the type of lawn mower (see above). So, mowers and riders, by definition, have large wheels, because they are designed for difficult terrain, and in a minitractor, the wheels must also withstand a fairly significant weight. But
robotic lawn mowers, on the contrary, are used mainly on flat surfaces with low grass, and they do not need large wheels.
If you have to choose among classic lawn mowers, where this parameter can be different, you should proceed from the planned working conditions. So, if we are talking about a flat lawn — you can not pay much attention to this indicator; but for rough terrain with pits, tubercles, ditches, etc., you should choose larger wheels — from 25 cm or more.
