Comparison Makita PLM4628N vs Makita PLM4620

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.

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.

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).

Type of drive provided in the self-propelled lawnmower (see "Features"). This moment is indicated depending on which wheels the thrust from the engine is output to.

— Rear. The classic version used in the vast majority of self-propelled devices. Such popularity is due to a number of advantages. Firstly, the rear wheels are located behind the cutting system, and when moving, they ride on already cut grass. Secondly, the main part of the weight in classic design lawn mowers falls on the rear wheels; and if the bag is used at the rear of the machine, then the centre of gravity is even more shifted back. However it is believed that such devices are less manoeuvrable than front-wheel drive; however, in most cases, this moment is not decisive, in addition, the design often provides for various tricks that make it easier to turn.

— Front. It is believed that front-wheel drive gives the lawn mower better steering. And mini tractors of this design are also less likely to get stuck in streams, puddles and other similar places: a front-wheel drive unit can slip through a difficult section by inertia, so that the front wheels catch on hard ground, while a rear-wheel drive machine is more likely to “sit down” with the drive wheels in sticky earth. On the other hand, in general, this option is less suitable for lawn mowers than rear-wheel drive — primarily because the drive wheels have to move on uncut grass (the only exception is some riders in which the cutting system...is mounted in front of the machine). In addition, for reliable traction with the ground, the centre of gravity of the device must be shifted forward. This is especially difficult to achieve if a rear-mounted bag is used to collect grass: as it fills, the weight shifts from the front axle to the rear, which in some cases can lead to loss of traction. As a result, front-wheel drive is extremely rare, mostly in bagless models and/or with the engine shifted noticeably forward for proper weight distribution.

— Full. In this case, full means 4-wheel drive at once. Its main advantage is its excellent cross-country ability: the unit “clings to the ground” with all four wheels, and the likelihood that they will all get stuck at once is extremely low. In addition, the design may provide specific features that further increase cross-country ability — for example, a differential lock. On the other hand, all-wheel drive is expensive both in itself (due to the complexity of the design) and in operation (due to high fuel consumption). The only exceptions are small electric robotic mowers (see "Type"), but they are produced in relatively small numbers — most 4x4 models have gasoline engines and are manually controlled. In light of all this, it makes sense to pay attention to this option only when you have to work on a vast area with difficult terrain, with which a “single-drive” unit cannot cope normally. But buying an all-wheel drive model for a flat lawn in front of a private house is hardly justified.

The maximum travel speed of the self-propelled lawnmower (see "Features") during operation.

Other things being equal, a faster model spends less time on work, especially when it comes to simple tasks. On the other hand, fast movement requires appropriate engine power, which in turn affects weight, cost, and electricity/fuel consumption. In addition, if we are talking about a traditional design lawn mower, when choosing, you need to sensibly evaluate your ability to “keep up” with the device. However, such models rarely reach speeds above 7 km/h — this is a quick step that is not a problem for a more or less healthy person. In addition, self-propelled units often provide speed adjustment (see above). But riders (see "Type"), where the operator rides on the unit, can reach higher speeds — about 13 – 14 km/h.

Note also that for the same engine power, higher speed means less power at the working head. So if speed is not of particular importance, it is better not to make a margin for speed, but to take a relatively slow, but “high-torque” device.

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.

The size of the engine installed in the petrol or diesel model (see "Engine type"). Power directly depends on this indicator, however, only engines of the same type can be compared by volume (see "Type of internal combustion engine"). And even in the same type of units of the same power, the volume can be different. In such cases, note that a larger volume means more fuel consumption, but the engine itself may cost less than a smaller one.

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.
