Cutting width
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).
Cutting height adjustment
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.
Grass ejection
Direction of ejection of grass cut by the lawnmower.
The main options for the direction of ejection are back or sideways; there are also models in which you can choose the direction. At the same time, we note that in classic units, the ejection back is almost always carried out
into the bag(up to the point that when the bag is removed, the hole is automatically covered with a lid), but when the bag is ejected from the
side, it may not be — this is convenient, for example, when mulching ( see above).
Also note that riders (see "Type") have their own specifics: in units with rear discharge, after removing the bag, it is necessary to install a special plug, and then the cut grass will simply remain under the deck. In some
mini-tractors, a similar way of working (without a bag) is provided initially; it is also considered a rear ejection, although the grass does not flow backwards, but downwards.
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).Deck material
The material from which the deck is made is a protective casing that covers the cutting tool of a lawn mower or trimmer. In modern mowers there are such options:
— Plastic. The cheapest and at the same time the least durable material.
— Aluminium alloy. The most advanced option: these decks are durable, lightweight and less prone to corrosion, but quite expensive.
— Steel. It has greater strength than aluminium alloy and costs less, but is heavier and more prone to corrosion.
