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 type
A type of bag used in a lawn mower to collect grass clippings.
—
Hard. Bags (containers) made of a hard material, usually plastic. Such a container is more convenient to unload than a soft one, it is more durable and reliable, but it weighs a little more.
—
Soft. The advantages of soft fabric bags are primarily low weight and the ability to fold after hours, which can facilitate storage. In addition, the degree of fullness of such a bag can be controlled by eye without any special indicators. On the other hand, soft bags are very inconvenient to unload.
—
Combined. Bags that combine soft and hard materials in construction; the upper part is usually made solid. This combination makes it easier to unload the bag and at the same time allows it to be rolled up quite compactly for storage.
— Is absent. The absence of a bag is characteristic of some varieties of mowing units — in particular, mowers and trimmers (see "Type"). In classic lawn mowers, it usually means that this model does not involve collecting grass — all cut vegetation remains on the ground. At the same time, most of these models have the function of mulching (see above), however, there are exceptions.
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.
Features
-
Self-propelled. In self-propelled lawn mowers, the engine rotates not only the cutting tool, but also the wheels of the lawn mower; thus, the user does not need to push it in front of him - it is enough just to set and control the direction of movement. This is convenient, but such models are more expensive than non-self-propelled ones. This is due not only to the complexity of the design, but also to the fact that such devices require more powerful engines - after all, power must be divided between the cutting nozzle and the chassis. For the same reason, a self-propelled unit will be less productive and efficient than a non-self-propelled analogue of the same power. However, some types of lawn mowers are by definition self-propelled - in particular, these are heavy professional models that would be difficult to push with your hands, as well as
mini tractor riders(see "Type").
-
Height adjustable handle. Possibility of height adjustment of the lawn mower handle, which allows to optimally adjust the device to the height of the user. This feature is especially useful for short or, conversely, tall people - by default, lawn mower handles are made for medium height, and it would be inconvenient to work with the unit without height adjustment.
-
Piano wheels. The lawn mower has special, so-called. caster wheels (similar to th
...ose used, for example, in supermarket carts). These wheels automatically turn in the direction of movement of the device, which significantly reduces the turning radius of the lawn mower and increases its maneuverability. At the same time, it is worth noting that this design is usually used only for the front wheels, while the rear ones remain rigidly fixed to the axle. So moving such a structure sideways still does not work.
- Flushing fitting. The presence of a fitting in the lawn mower for connecting a garden hose; usually such a fitting is located on the deck and is designed for a standard connector used in hoses. In accordance with the name, this function allows you to rinse the deck and blade of the unit, removing grass residues and other contaminants from them: just connect the hose, turn on the working nozzle and give water. This is much more convenient than removing the deck and washer blade by hand - especially when it comes to a heavy professional mower or rider (see "Type").
- Cup holder. The presence of a cup holder in the design of the lawn mower - a specialized stand for glasses and relatively small bottles. Such a stand usually has a characteristic recess where a container with a drink for the operator is installed. Often, cupholders are made in pairs, they are placed on a separate panel between the tubes of the handle of the unit. There are coasters in traditional lawn mowers and riders (mini tractors).Revolutions (electric motors)
The maximum speed that the engine in an electric mower can run at (see "Engine type").
It makes sense to compare according to this indicator only engines of the same power. In general, higher rpm improves performance but reduces torque. Conversely, a relatively slow engine will be inferior to a “fast” one in overall speed, but it will better cope with dense dense vegetation. So it’s worth choosing by engine speed, taking into account what is more important to you — speed or efficiency in difficult conditions.
Noise level
The level of noise produced by the device during operation. Usually, a certain average indicator is indicated in the characteristics — in the standard mode of operation; however, the actual values usually do not differ much from the claimed ones.
The lower the noise level, the more convenient the unit to use and the less tired the operator. In the case of lawn mowers, this is especially true, since such equipment is quite noisy — even the quietest models (some robots) give out about 47 – 48 dB, which is comparable to talking at an average volume. Note that the decibel is a non-linear quantity, and it is easiest to evaluate the actual loudness using comparative tables. Here is the simplest table for the values found in modern lawn mowers:
— 60 – 65 dB — talking in raised tones at a distance of about 1 m;
70 dB — loud conversation of several people at the same distance;
75 dB — loud laughter at a distance of 1 m;
80 dB — motorcycle engine, medium power vacuum cleaner.
90 dB — loud screams, freight car at a distance of 7 – 10 m;
100 dB — a subway train or a loud car signal at a distance of 5 – 7 m, an industrial workshop;
110 dB — tractor engine at a distance of about 1 m.
In addition to subjective sensations, there are specific sanitary standards that limit the impact of strong noise. So, according to European standards, noise of 85 dB is allowed to be heard without protective equipment for 8 hours, 91 dB — 2 hours, 97...dB — half an hour, and 103 dB — only 7 minutes. So when choosing a unit, you should take into account the duration of work with it — with high noise, you may need protective headphones.
