Despite all the talk about global warming, the winter in most regions of Russia are still plenty of snow falls. Therefore, the owners of the cottages every year the question arises: how to clean it from the site and especially the roads and footpaths leading to the house. The traditional method - using shovels - maloproizvoditelen and inconvenient, also does not guarantee good performance. Optimal solution - the use of small snowplows compact snowthrower (harvesters), the benefit of a wide range of leading manufacturers allows you to choose a car that is suitable as its characteristics, and value. The operating principle of most of these machines is very simple: the engine drives the screw clamps, which collect snow and throw it through the chute at a certain distance. The bulk of the market snowthrower - units with gasoline engines. Recommended fuel - brands AI-92 or A-95. Fuel tank lasts an average of 1,5-2,5 hours on one filling. The main difference between the combine - the power and the width / height snegozahvata. These figures relate to each other: the greater the power of the machine, the greater the amount of snow it can recycle, and therefore it needs snegozahvat having a greater width and height. Power range of modern gasoline snowthrower - from 6 to 11 hp It is clear that the power of the engine intake and the amount of snow affect the performance of the combine. For example, combine the 6 hp with a width of 53 cm snegozahvata can process per hour, about 33 tons of snow, and combine for 11 hp snegozahvata with a width of 92 cm - about 70 m. Of course, performance of the machines depends not only on their characteristics, but also on the terrain, the number and consistency of snow (new-fallen, wet, packed, etc.). Snowthrower divided into self-propelled and self-propelled. The first has to push his hands, the second move independently. Self-propelled machines - is wheeled units, the lightest (weighing about 40 kg) and thin (about 6 hp), with a width snegozahvata - no less than 52-53 cm and its height - about 30 cm direction and distance of ejection of snow usually they are also regulated by hand - with the handle attached to the bell. The distance by which they can throw the snow, usually no more than 10 m. The performance of self-propelled harvesters mean, besides clearing using them wet and packed snow requires considerable physical effort. However, to combat the snowdrifts in a country cottage, they should be fine. The more so because often the edge of their rubber-coated metal screws, so removed the surface is not damaged, so you can safely clean out the combine paving slab or asphalt tracks. In self-propelled models have the drive to the wheels or tracks. Wheel snowthrower is very maneuverable and have a high rate, but may slip on the deep snow, despite the fairly large diameter wheels and tires profiled. Track aggregates less maneuverable (although new models are even function of rotation in place), but have greater stability and maneuverability, so that will overcome even the high drifts. Which model to choose? If the area are not uncommon shrubs, flower beds, small architectural forms, if you often have to bend around corners, it is better to buy a car wheel, and if necessary to clear a large area with relatively flat terrain - buy caterpillar. Unlike the majority of non-self-propelled combine harvesters have separate systems snegozahvata: front screws are located, and then - regardless of their high-speed rotor. Augers crushed the snow, the rotor - throws. With this design, first, to increase the range "flight" of snow - up to 14-18 m, and secondly, it is possible to cope even with thick snow. In addition, many self-propelled models with the power of 7 hp have serrated augers, so that they afford even the highly compacted snow. Among self-propelled combines are models of medium and heavy class. Middle class weigh 70-100 kg, and their performance - 35-60 tonnes per hour, heavy-duty weighing about 200 kg, and their performance - up to 70 tons per hour. Snowthrower middle classes are designed for daily clearing of vast areas, heavy-duty machine suitable for fighting with the snow on an area of ??several hectares. A few words about the complete set of self-propelled combine harvesters. They are governed by speed, but it happens in different ways: by means of mechanical or hydrostatic transmission. Manual is not very different from the corresponding gear in the car: multiple speeds for moving forward, neutral, and one rate (sometimes two) for the reverse. The hydrostatic transmission allows you to increase or decrease the speed, to include back up and adjust its speed without changing engine speed, that is on the move. We need only to press a lever located on the control panel. With the "hydrostatic" much easier to maneuver, because they do not have to stop each time you want to change gear. In addition, it allows you to increase speed smoothly, without jerks. Track model of a new generation equipped with a gasoline engine that drives the screw-rotor, and two electric motors, each of which sets in motion a caterpillar. While running the onboard computer, these engines operate independently. Thus, the combine speed adapts to the workload for the unit at the moment, regardless of screw speed-rotor. So that the engine does not stall. However, two separate electric motor, "responsible" for the tracks, provide the best handling snowthrower. If the self-propelled models, control over the release of snow was carried out with the handle attached to the bell, and demanded certain physical effort, then "self-propelled guns," he mechanized. On the control panel is a pen, regulating range "flight" of snow, and the shaft, changing the direction of his "flight". Do expensive processor is electrically operated control both range and direction of ejection of snow: you need only press up and down or left / right switch on the control panel. Thanks to this "mechanization" can be controlled release of the snow, without stopping the processor. Track snowthrower heavy class can also have the pedal or lever to change the height of screw. In addition, a powerful model "self-propelled guns, are generally equipped with a locking system of one wheel or a caterpillar. This gives greater flexibility bulky and heavy harvester. Since early in the winter it gets dark on many models combine provides a powerful halogen lamp, usually calculated at two levels of brightness (the near and distant light) and the ability to turn up or down. And the latest models of "serious" snowthrower is lighting control panel. With yet another unexpected problem you might encounter, acquiring a more expensive model plow, equipped not only with manual start, but the electric starter. According to the laws governing safety, adopted in foreign countries, electric starter, nominally set on these models are 110 volts. Therefore, it is necessary to acquire additional ballast or, in extreme cases, have left long ago disappeared from the sales step-down transformer. Despite these disadvantages, an electric starter, although it increases the cost of the unit, making the beginning of a much more pleasant and, most importantly, you do not spend time and effort while you try to start the engine on the bitter cold with a manual starter. When operating small snow machines, it is desirable not to forget about the maximum working hours without stopping. Usually this time of limited supply of fuel, ie, the size of the gas tank. If you spent the whole tank, you do not need to immediately replenish the supply of fuel and to continue working. Need to rest and cool down your mate at least 20 minutes. If you ignore this advice may be followed by overheating and engine failure. Unfortunately, all the snow machines are not multifunctional. Very rarely, together with a screw mechanism proposed cylindrical brushes, scrapers or simply dumps, but it should be noted that its main task - cleaning the snow - they do fine. At all snowthrower provides for a system of protection against misuse of the unit and the system protect the operator from injuries. For example, the self-propelled machines for protection gear screws are attached to it via a special pins made of soft metal. Keys are designed for specific effort, so if you combine rest against the ice, curbs or iron girders, the pins are cut off, stopping the screw, and save from damage gear. Next on the operator's security processor. If on the way to meet the combine, for example, a bottle, then screw it to grind, but a special mesh to delay the big bell fragments. In addition, Bell can not turn towards the control machine. To make out from under the screws do not fly out the snow on top of snegozahvata a protective visor. The main body of the combine secured a special stick for cleaning clogged auger, so as not to get into snegozahvat bare hands. Finally, moving the machine stops automatically as soon as you release the handle clutch transmission wheels.
