Comparison Tekhmann TLM-4179 vs NAC MEX55-PE

The capture width provided by the unit, in other words, the width of the strip of land cultivated in one pass. In fact, this size corresponds to the width of the working nozzle.

The large working width is useful when processing large open spaces, as it allows you to finish the job in a small number of passes. On the other hand, for hard-to-reach places, relatively narrow tools are better suited, able to go where a wider unit will not fit. In addition, the width of the tool directly affects the weight and price.

In general, it makes sense to compare in terms of working width only units of the same type (see above). However, it is worth noting here that trimmers do not differ so much from each other — most models capture from 25 to 45 cm (and a wide processing band is provided by moving the nozzle from side to side). As for the other types, in the most modest models the capture width does not exceed 40 cm, in the heaviest and most powerful it can be 56 – 60 cm or even more(in mini tractors — up to 1.5 m).

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 number of cutting height settings provided by the lawn mower. The more such settings (with the same adjustment range) — the more accurately you can choose the mowing height. Note that in some robots (see "Type") this number reaches 30 or more with a range of 30 to 60 mm; in other words, you can select the height to the nearest millimetre.

The cutting height adjustment method provided in the machine.

— Synchronous. Adjustment carried out "in one movement" — as opposed to the manual described below. In traditional lawn mowers, it is usually carried out by a lever that changes the height of all wheels at the same time; in other units, not the wheels, but the cutting tool itself, can be adjusted in height. Anyway, synchronous adjustment is much more convenient than manual adjustment, and for some devices (for example, robots and riders, see "Type") this is generally the only technically possible option. However, in classic mowers, such a system complicates and increases the cost of construction.

— Manual. The meaning of this type of adjustment depends on the type of device. So, for trimmers, this is almost the only possible way by definition: in them, the cutting height is regulated by how high the operator holds the working nozzle. In lawn mowers, manual adjustment means that you need to separately adjust the height of each axle, and even each individual wheel. Such systems are simpler and cheaper than synchronous systems, but less convenient to use.

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.

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.

- 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).

Model of the engine installed in the lawn mower. The main performance data of the engine is usually indicated in the general data for the unit. However, knowing the exact name of the motor, you can find more detailed information on it — from specific data to reviews and reviews. Also, data on the engine model can be useful when searching for spare parts or consumables.
