According to their characteristics, lawn mowers are divided into many subspecies, so that each user can choose the best option for himself.

The classification of lawn mowers is based on the following criteria:

  1. Type of movement: self-propelled or not.
  2. Drive: rear or front wheel drive.
  3. Material of the outer case: metal, plastic, shockproof plastic.
  4. Grass catcher volume (the larger it is, the less often you need to make stops for cleaning).
  5. Engine power.
  6. Type of food: electricity or gasoline.

For most models, optional nozzles are offered.

Electric

All Bosch lawn mowers are rotary. Under the deck, a knife rotates in a vertical plane, driving the cut grass into a bag on the back of the unit.

The Bosch range of lawnmowers is divided into 2 subspecies:

  1. Powered by an external power outlet.
  2. Rechargeable, in which the motor runs on a power supply installed directly on the mower.

The second type is more expensive, but the first has a significant drawback: during mowing, it is necessary to ensure that the wire does not fall under the cutting unit. Working at high speeds, the knife is able to interrupt the wire.

Rotak 32

Compact power mower powered by an external power outlet. The cutting height is set for each wheel separately and can be fixed in 3 positions: minimum. 20 mm; maximum. 60 mm.

The collection of grass is classic: in a plastic bag attached to the back of the unit. The main advantages of the model include:

  • light weight;
  • powerful engine with overheat protection system;
  • Convenient carry handle.

The numbers in the name indicate the width of the strip, which can be processed in one pass (32 cm). Recommended for plots of no more than 3 acres.

Rotak 40

The Bosch Rotak 40 electric lawn mower has received many innovative solutions. The principle of operation is standard: the user pushes the tool in front of him, the mowed grass falls into the bag-catcher mounted on the back. The cutting height is immediately adjustable for all wheels with one handle on the top of the chassis. Floating installation: from 20 to 70 mm.

The updated Rotak 40 (Gen 4) model has received new guides that allow you to effectively cut plant material even along the edge of the lawn and work in hard-to-reach places. There is no mulching function, but there is LeafCollect. the ability to not only cut grass, but also carefully collect fallen leaves. Recommended area of ​​the plot is up to 10 acres inclusive.

Rotak 320

Rotak 320 is a budget version of the previously described Rotak 32. All model parameters are identical, with the exception of the electric motor. The number 0 in the model name indicates a kilowatt motor, while the original one is 1.5 times more powerful. Everything else: the width of the cut, height adjustment (3 steps) for each wheel separately, the external design is identical.

Arm 34

The main feature that distinguishes the Bosch Arm 34 mower from similar models of the brand is the country of manufacture. This is China.

The diameter of the knife is 34 cm. Thanks to ergonomic handles and a convenient start-up system, the user can work for a longer time.

Arm 37

Arm 37 model differs from the previous one only in the width of the passage. Also assembled by China, has convenient handles and a launch system. There are 5 positions for changing the mowing height.

Arm 3200

Like the Rotak 320, this model belongs to the budget options. The first pair of numbers indicates the mowing width, the next. on the power of the engine. It has all the functions of Arm class models: handles, adjustable cutting height, convenience and maneuverability. At the same time, a motor of lower power is installed, which positively affects the cost.

Other models

For mowing large lawns (over 12 acres) there are special offers from the Advanced series. Such models differ in motors of 2 (or more) kW, the width of the passage is up to 50 cm, large bags for grass and the corresponding cost.

Rechargeable

This type of mower is only gaining popularity. It does not require power from an external outlet. On average, such a unit can work for an hour or more from a single charge.

The pluses include greater mobility due to the lack of cable. Some models have the option of express charging. One battery is included in the package, so the price of such options is higher than those that work from the alternating current network. The letters Li in the model name indicate the type of battery: lithium-ion.

Rotak 37

The Rotak 37 Li comes with 1 36V / 4Ah battery. A charger is included. Full charge takes 2 hours

In one pass, a strip 37 cm wide is cut. The height of the cut is changed by pressing one handle fixed in 5 positions. Allowed limits: from 20 to 70 mm. The machine has a 40 L grass catcher and Syneon Chip for smart energy management.

Thanks to convenient nuts, the model is assembled simply. They can also adjust the length and tilt of the control knobs. A sharp knife for a lawn mower makes it possible to process heavily overgrown areas, and a special comb along the guides will allow you to mow even tightly against the fence or buildings on the site.

Rotak 43

For large areas, it is recommended to use the Rotak 43 Li model with two batteries. The second serves as a spare (a place in the compartment for only one). If you charge both the supplied device, downtime is reduced to the minimum required to replace the battery.

The width of the passage is 43 cm. The height can be set in one of 6 positions by turning the lever, while the system simultaneously raises / lowers all the wheels. Height limits: from 20 to 70 mm. Under the cover is a standard rotary knife.

Convenient handles, a one-button starter, a window for assessing the fill of the grass catcher and a spare battery. all this relates to the pluses of the model. The same innovative guides will allow you to process areas near the edge of the lawn or any obstacles.

Less popular

With a pair of batteries (one spare), the Rotak 32 Li is also available. In one pass, a strip of 32 cm is cut. The height of the cut is changed by rearranging the wheels.

3 positions are available:

  • 30 mm;
  • 45 mm;
  • 60 mm.

Handles are standard. Thanks to a special screw system, you can adjust the convenient tilt and height. An interesting difference is the noise absorption system developed specifically for this version, which allows the lawn mower to be used even in urban environments. Like other battery models, there is a smart power management system.

The main structural elements of the Bosch Rotak 34 lawn mower are the wheel chassis, the handles with control, the machine, the cutting system and the storage box. Joint and coordinated work of each of these nodes gives the device mobility and efficiency of operations.

This is facilitated by the following features of the assembly elements:

  • Bosch’s own engine with an installed power of 1300 watts, transmitting the highest working torque of 20 Nm in low gear to the cutting working system.
  • Installed overheating protection also limits the current supply during power surges, this increases the life of the motor.
  • The rotary cutting system is armed with a central adjustment of the position of the knife by means of the 1st lever, and not by using the option of the position of all wheels, as is done with other similar mowers.
  • The ergonomic shockproof housing together with the design features of the cutting apparatus (the introduction of special guides) allows for a very clean cut at the walls and borders.
  • Ergoflex adjustable handles allow you to adjust their position in the most comfortable way.
  • An additional handle on the body is used for comfortable manual carrying of the mower.

Principle of operation

The drive to this mower is installed only on the action of the working equipment, and the wheeled chassis serves to comfortably move it by the operator. The general action is fairly common, similar to other rotary lawn mowers:

  1. The engine drives the tool with blades.
  2. High-speed rotation of the knife repeats the work of a hand braid. a horizontal cut of grass.
  3. Herbal mass is poured into the back of the machine, where it accumulates in a special box.
  4. After work, the filled box is freed from weed in a comfortable place for this.

Device and principle of operation

What does it consist of

Let us examine this question on the example of the mechanism of the belt to the lawn mower vega x pj457 180j. Changing the mower drive belt. And so, from 2 rows of rings of endless direction, which are placed parallel to each other specifically in the groove area of ​​the so-called multiple “elements”. They, in turn, are attached to each other in the form of a typical ring. This installation was made in such a way that the groove itself had the opportunity, so to speak, to open specifically to the peripheral outer side.

It will be important that this same element has the presence of the surface of a part of the protruding guide character. This is necessary in order to create a retention of a typical ring in such a way that the special rings included in its devices simply do not separate from each other and from the groove itself.

Features of work

It should be noted that the surface with the name “guide” produces the formulation of the specific force of the pushing direction specifically to the inner side of the belt, all the while pushing one particular ring to one of the special end surfaces. This very same pushing component force, which is oriented to the inner region, makes a peculiar attachment precisely to the lateral outer side of the ring, which at this moment is pushed.

How does it work

First, it should be noted that a typical gearbox, which has gears in the gear direction, provides specific support for a specific configuration specifically in the gearbox, which has gear steps. The same goes for the stepless gearbox, which in turn is responsible for the specific variation of the gear case.

Specifically, these features are available as a typical box, designed specifically for power output, which is made between certain rotating elements.

Vega x pj457 180j

It is important that when the belt itself rotates the drive pulley, and at this moment we express it this way, applied to the drive and driven pulleys, then in this case it becomes a prerequisite for the appearance of a certain friction force, which is observed specifically between the drive pulley and a special element.

At the same time, there is a force, the so-called “compression”, which in turn applies directly to the elements themselves in the direction in which they are placed, in other words, in the direction where their coefficient of thickness is larger relative to the moment of the drive pulley specifically driving.

While the force of a certain compression has already been “sent” to a particular element, which actually fully maintains contact with the driven pulley, then the typical friction force produces a formulation specifically in the part where the pulley, follower and element are in contact.

As follows, by means of this kind of mutual transmission by force, a moment is made that rotates created for the movement of the driven pulley. In fact, in such a way, its working power is transferred to the belt itself. You can find out exactly where the belt is located in such units using the example of the Polish rotary mower device.
