Comparison Konner&Sohnen KS 38LM-BL vs Konner&Sohnen KS 38LM

The maximum cutting height that the lawn mower can achieve is the maximum height of grass that can be left after the machine has passed.

This parameter is relevant mainly for those cases when you want to leave the grass on the lawn relatively long. In addition, lawn mowers with high cutting heights have a wide range of mowing adjustments.

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.

Indicator indicating the degree of filling of the bag. The design and capabilities of such an indicator can be different: for example, in some models it only gives an overflow signal, in others it allows you to determine the amount of grass in the bag at any time. However, anyway, this function provides additional convenience: it allows you to evaluate the fullness without removing the bag and without interrupting work.

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.

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.
