Which tractor is better
All essential tractors are equipped with caterpillars and wheels. And in this case, it’s the most important thing, because in other, obvious technical characteristics, it’s easy to get close and take advantage of your opponent ’s strengths . In other words, the retailers of tractor equipment are working on changing the number of shortcomings in the skin category of tractors and on adding to the already obvious new capabilities . To characterize the whole activity more briefly, then three words hang out: what a tractor is the best.
Frolich , an American winegrower from the state of Iowa , designed the first with a 16 hp engine, which instantly collapses forward and backward. For whom the author did not call his brainchild a tractor. Wanting such a term used to go already since 1859 engine " - "traction engine". Sweat the wine-drinker after falling asleep by the Waterloo company Gasoline Engine Company And in 1918, having bought House of Deere Budinok, this foundation became the starting point for the appearance of the famous John Deere tractor brand in the whole world . I wanted to get to Frolіch Deere's car, having already let out his rozrobka - the " Dain " tractor. But the spivpratsya with Frolіch brought the company John Deere just success.
justice, varto respect, that three years earlier in Russia (1880), the winemaker Blinov registered a patent and in 1888 released the first copy. The car sounded like a modern tractor - two caterpillars, the shape of the body, but the development of the development did not take away.
At the same time, the town of Waterloo in the state of Iowa took away not only the "title" - "Tractor Place in the USA", but also the work of the city. The first rocks of the tractor were launched with wheels, but with metal wheels and spikes - a prototype of caterpillars? However, the stench was still weak, pratsyyuchi on gasoline fire. Ale, until midnight, already a few years later, engines on a diesel fire were launched. The culprit of such motors, Rudolf Diesel, zoomed in on his business (the "Diesel Engine" company), in which Adolphus Bush, the founder of the " Budweiser " brewing company, financially supported. A further development of this mechanism in a seemingly prichipny and overhead possession was only seen in 1958 at the Swedish company " Alo " (now the brand name is " Quicke "). In the course of time, the choice of tractors was improved, various innovations were announced, calling for the best possible completion of tractor equipment, and competition was born in this industry under the slogan: which tractor is better: caterpillar or wheeled.
Crawled tractors, yakі stinks in pіvnyannі z kolіsnimi
In a flash, caterpillar transport is associated with all-round transport - it’s hard to walk everywhere and “take in” in the caterpillars.
And also a caterpillar tractor to repair a smaller vice on one area of the field, which reduces the strengthening of the soil and does not ruin the structure of insufficiently drained soils . some have a lot of organic matter. The price difference at the pressure on the ground is explained by the fact that the area of the trucks is 40-60 more square meters, while the difference is significant for the wheels. Less strengthening of the soil - more fertility. True, all those who could not be hurt by a tractor in the distance could be “broken” by a combine harvester and other wheeled equipment that moves in the field, but it’s hardly possible to reload it all.
Tse povnyannya lie on the surface . how about dig deeper? A recent technical laboratory near the state of Nebraska (USA) found that on dry soils, a wheeled tractor would be more effective for sensi- tive staining of rain-fed materials. In the minds of wet soil, as well as with greater efforts, a caterpillar tractor will become more economical. And how to pour in not less than different soils, but think about climate change, different levels of innovation? For the purpose of testing viable spivrobitniks of the Laboratory, experiments were carried out over a period of many years. The last two tractors were Case Steiger 600 and Case Steiger 600 QuadTrac . As you can see from the names of the models, the purity of the experiment was done.
When changing over concrete roads with the same speed, the tire version was effective for fire - 3.4 kW / year per liter, versus 3.24 kW / year for the caterpillar brother, the effective difference was 5%. I want to explain this issue simply because the weight of the tire model is smaller . lower in the caterpillar, and in a different way, the smaller support of the stiffness was the wheel of the zavdyaki of the yogo round shape. But tractors spend more money during their working hour near the field, less on the roads.
For this reason, the last tractors recognized the marks in the minds of the work on dry soil and after the harvest of wheat. Having offended the tractors, they "navantage" the reason for the possession of a 9.5 ton haul and took away taxes - for the wheeled tractor, the amount of hay was less by 7.5%. Ale, with the transfer of these tractors with the same trailers, the same field, ale after oranges, caterpillars, showed an increase in efficiency - by 4.6%. For the first time, the increase in the moisture content of the soil increased and the difference in the effectiveness of the fire on the measles of the caterpillar mechanism.
Approximately similar to the fallow of the caterpillar tractor over the wheeled tractor was the increase in the advancement of them to the maximum. So, with a load of up to 13 tons, the most successful wheels were only on the stubble, behind the edge, the caterpillars led the way with a result of 7.4%, and with a heavily soiled soil, the result increased further to 7.9%. Looking straight ahead, she shifted. The fact that, at the same time, because of the important possessions for a wide grip, the caterpillar tractor will be more effective on dry soils, is even more impressive. The relief of the field also flows in - on the foothills at the wheeled one, you can stick tightness . but not a traction drive, which should reduce the speed of transferring, and with it, the productivity of the tractor and increase the efficiency of work. For the mind of the victorious in the rehabilitated minds of a caterpillar tractor, it is allowed to spare up to 50-70 liters of firewood for a 12-year-old son.
The caterpillar units have a couple more, maybe not important floorings . but even more effective kozirivs - the stinks of the building turn around at any radius, standing on the ground, and just don’t give respect to the wounds on your way. In the field, building development is obviously not needed . Prote in the middle of the court of the state can be more cordial.
Search for ways to better serve the interests of the agrarians
Turbota about the rarity of soils. about economy of rainfed materials in turbulence of all agrarians in the world and branded companies, for example, Case IH, John Deere, which are growing on the water supply and producing more new tractors on caterpillars. improve your ability.
With the minuses of this type of tractors, the varto guess about the deuces and hardships when changing the trajectory of the road, after which the stink is wasted. This is explained by the greater inertness of such units and for the її podlannya, additional tension is needed. Some models have the power program boost , which compensates for the deficiency of tension.
It would be unfair not to mention that current wheel models of tractors can have a lot more throughput. Especially the mechanisms from the front axle - for them there may be no inaccessible paths. The stench is still defrauding caterpillars, but trying to catch up is trying. True, here tractors on wheels have the opportunity to build up an exchange . only 45-55% of the stiffness of the engine can be changed on the traction force, and the tightness line goes to the bottom of the slip, to adjust the amount of that support of the stiffness force. The coefficient of slippage of the caterpillars is trimmed here at a rate of 5%, while for the wheels of the veins it becomes 20% - the axis of the star is the savings in caterpillar tractors! This factor allows you to start a field job early on a caterpillar tractor and save the water in the land after the snow.
While for agribusinesses, the factor of universality of wheeled tractors may appear to be a more important factor, since they have significantly more advantages in pairs with caterpillars, even if they are still good mainly in the fields, and tractors on wheels are slender for transporting vantages to faraway places, while carrying out different everyday life and repair work, as well as indispensable during the maintenance of the inter-row - you definitely don’t know what’s in the caterpillars. I, like "cherry on the cake" - a wheeled tractor is cheaper for a technical service. Metal tracks cost more expensively for the most modern wheels, and the humic replacements still cost more, lower than metal. Before the replacement of metal trucks, they can be provoked by repeated transfers of the tractor on their own from field to field for a distance of a lot of kilometers in Russia with asphalt or concrete. Although these problems are brewing behind the help of a caterpillar tractor, some of the technologists already produce such mechanisms. That competition is not only between caterpillars and wheels . and th "at the middle" of caterpillar units.
The practice of choosing tractors in different types and manufactured by different branded companies shows that even more often, even if not for a long time, the advantages and effectiveness can be taken away, or used in the fallacy in the correctness of the organization of the work of the state, in the case of improving the small nuances of the great skin models in all the specific models , as well as the types of evidence from the robots of this machine in specific minds of your state. And the shards of skin development can have their own, it is possible to create exclusive experiences, but all the food is in that - what do you need the stench for?
One more experiment for por_vnyannja
For the last three years , New Holland Agriculture has announced two new models of tracked tractors in the T9 SmartTraxTM series , which are being manufactured at the factory near Fargo (USA). The novelty is in the presence of replacing two long tracks, some short ones and a gum one. Cі machine dosit hard, with a zchlenovannoy frame and vіdminnim balancing. In this case, the optimal copying of the relief of the soil is reached independently from the frontage on the rear suspension of the tractor. Zavdyaki tsmu koefіtsієnt zcheplennya z the surface of the field podtrimuєtsya at the maximum level. and the coefficient of slipping on the pack is minimal. In addition, these models are equipped with reinforced tracks, which successfully add stone grunts in kar'єrakh. But no matter what, it would seem, the team of engineers decided to carry out a technical experiment on the topic “Wheels and caterpillars”, which was designed for the Fendt and Challenger tractors for this tractor.
Simply increase the tension of the engine often does not lead to an increase in traction tension, but the strength can be transferred to the ground.
Mezha here means physics. It seems that a lot of factors are added to the behavior of the tractor in traction robots - so it is: masa (zocrema ballast) the area of \u200b\u200bthe yogic support, slipping and slipping from the ground.
Masa. For vikonannya traction robots tractors need a lot of weight. And it doesn’t matter if the wheeled caterpillar chi - vin can’t pull more for the power vaga. Sound standard tractors reach the indications at the borders from 04 to 07 of their mass. The main coefficient of the traction force.
For example , a tractor with a haulage of 10 tons and a coefficient of 0.5 develops approximately 5000 daN chi 5 tons for the minds of the field. So if it is necessary to pull more weight, it will not be enough for the tractor to simply increase this tension, but it will be necessary to increase this weight, but to spend more money on the advantage. The very name of the tractors with articulated tracks is a great mass, so that they could transfer to the ground the exhaustion of the engine of 600 k.s. Such tractors could carry 27 tons with a total load of 27 tons, which would be more for the weight of the Fendt 936 , and with the improvement of the minimum coefficient of 0.5, it would have seen more, less than 13 tons.
.
An important moment is ballast . There can be a significant injection on the susilla traction: the increase in the traction of the tractor with a mass of 10 tons per 2 tons, the increase in the rozrahunkov traction of the susilla by 1000 daN chi 1 t . yakі dodatkovo navantazhuyut the back of the whole mechanism
This is how the traction control system functions when the tractor is rewound with a plow (for example, when the plow is tucked with a larger solid plot of soil) - the system automatically raises the plow by a sprat of centimeters. In okremih models specially zbіlshhuyut navantazhennya on the rear all traction. І y zv'yazku z tsim chinnik tractors zі standard designs orientated tripoint zadnannya . Adzhe vreshti-resht tractors are guilty not only of burdening vantage, but also of carrying yoga. Tires of a larger size are installed in the back, and a smaller one in front. A tractor with such a difference in wheel diameters becomes more maneuverable.
When transporting especially wide ones, it is necessary to carry out important hanging units, installed on their own chassis, with the help of the tractor traction (behind the 1st rear suspension) through the daytime of the load also during the day.
At the same time, the situation is different for articulated, integral and rich tractors: first, the stench is towed, and not transported on one's own, so the mechanisms are shifted on great wheels of the same size, and the weight is equally on the scale axis .
Hinged-membered models are especially important . for those on the front line, up to 60% of the mass and їx 20 tons of weight can be converted to 27 tons for the help of additional ballast, for which the tractor will become simply the most powerful bicycle .
Since a standard caterpillar tractor often does not work between its capabilities, then some additional ballast can appear even more than a horsetail. Standard caterpillar tractors are too short for swivel-joints and are prone to a colossal torque, which is transmitted by a wired gear placed in the rear, the tractor can “stand on dibs”. In order to avoid such situations in the areas of the supporting thrust, it is necessary to increase the traction force of the mechanism behind the auxiliary ballast at the frontal or running part.
The deposited material confirms the fact that there are many problems in robots, both caterpillar and wheeled mechanisms, and illustrating the nuances of their manifestation. Zvіdsi, zavazhivshi their consumption, slavish їх зі their possibilities, and also vrahuvav all obvious and no less obvious features of a particular model of the tractor can be done correctly and it is important to make a decision, which tractor is better.
