Motor power

Lawnmower engine power expressed in horsepower. The common unit of power these days is the watt, but gasoline and diesel engines (see "Engine Type") are traditionally referred to as hp. Some units are easy to convert to others: 1 hp. approximately equal to 735 watts.

In general, the more powerful the engine, the more performant the mower is and the better it handles with heavy work such as cutting thick grass, bushes, etc. On the other hand, high power has a corresponding effect on fuel consumption, as well as the weight and price of the engine. In addition, it should be taken into account that different types of mowers (see "Type") differ in terms of power requirements. For example, among trimmers there are many models with a capacity of 0.7 – 1.3 hp., for gasoline lawn mowers, the minimum power is already in the range of 1.3 – 2 hp., and for mowers, at least 2.5 hp is required. . So you can only compare units of the same type in terms of power. Detailed recommendations for choosing a mower depending on its type and features of the planned work can be found in special sources.

Motor power

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.
