Comparison AL-KO Classic 3.25 E vs Bosch Rotak 32 0600885B00

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.

Lawnmower engine power expressed in watts. This designation is used absolutely for all electric models (see "Engine type"), and it is also often found in gasoline and diesel units along with horsepower (these units are clearly related, 1 hp is about 735 watts).

In general, the more powerful the engine, the more performant the mower and the better it will cope with heavy work such as cutting thick grass, bushes, etc. On the other hand, high power has a corresponding effect on fuel / electricity consumption, as well as the weight and price of the engine. In addition, note that the power requirements depend on the type of mower itself and its engine (see above for both). For example, for most robots, the power does not exceed 500 W — more, taking into account specialization, is not required, besides, otherwise the devices would turn out to be too bulky and heavy. Trimmers and lawn mowers of similar power are only electric, and the power limit for power tools is 2500 – 3000 W when powered from the mains and 1500 – 2000 W for battery models. But in gasoline tools, the minimum power is about 500 – 1000 W for trimmers and 1000 – 1500 W for mowers; the maximum value can exceed 4 kW.

Detailed recommendations for ch...oosing a lawn mower depending on its type and features of the planned work can be found in special sources.

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.

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.
