In this video Big Tractor Power looks a 10 new tractors to watch for in 2021 from CLAAS, FENDT, John Deere, Case IH, Massey Ferguson and New Holland.
A machine is called a set of devices consisting of various machine elements, such as gears, bearings, and shafts, to convert any type of energy into another energy, perform work using a certain power, or create an effect. Electronic or organic devices that do not have any mechanical parts are also called machines. Machines have been developed to assist or completely replace human or animal power in the performance of a specific job or in the performance of a physical function. They cover a wide range of devices, ranging from simple machines such as a lever, inclined plane, spinning wheel, to very complex systems such as a modern car. Machines thermal, chemical, nuclear, or electrical energy into mechanical energy, or vice versa, or can only work in the format can function as transfer or adaptation of force and motion. All machines have input and output equipment and adaptation or conversion and transfer equipment. A machine that receives input energy (input) from natural sources such as wind, streams, coal, oil, or uranium and converts this energy into mechanical energy is called a primary engine (primary engine). Windmills, water wheels, turbines, steam engines and internal combustion engines are the primary movers. The output energy (output) obtained from these machines can be fed as input to other machines, such as an electric generator, hydraulic pump, or compressor, mostly through rotary shafts. These last three devices belong to the class of generators (generators; the electrical, hydraulic and pneumatic energies that are the output of these devices can be used as input in electric, hydraulic or air engines. These engines are used to operate machines that produce various types of outputs, such as material processing machines such as machine tools, packaging and transportation machines, or sewing machines and washing machines.
Machines that do not belong to the class of primary inverter, generator or motor are called processors (operator machines); the category of processors includes all manually operated tools such as a calculator and a writing machine. In some cases, machines of all categories are assembled into a single unit. For example, in a diesel-electric locomotive, the primary motive power is the diesel engine; this engine provides power to the electric generator, the generator also drives the engines that turn the wheels.
