shear bolt
shear bolt is kind of saftey in machines and agricultural machines .
for example the baler fly wheel have a safty system through the shear bolt .
when there is extra load happen instade of plunger broken or any other main part . the shear bolt broke before any damage happen
the shear bolt must be made off specific material such and specefic dimention . and according to the loads it must be designed accuratly

Irrigation
Under irrigation, these procedures are summarized, where an irrigation using stationary or mobile Spraying is done. The irrigation is mainly used in humid climate areas operated. The water pipes will have to the facilities in the field pumped. Depending on the type, there are: irrigation with fixed, mobile and teilortsfesten Full and complete plants. As it is, more precisely between individual irrigation, irrigation district, or roll Rollzugberegnung finished (self) irrigation differ. The irrigation provides few demands on the surface of the area. Accordingly, it is also uneven terrain and independent irrigation, so that may be burdensome Planierungsarbeiten as well as the construction of dams, ditches or omitted. About the facilities may also be multipurpose irrigation. Thus, irrigation facilities for irrigation and frost protection for the application of fertilizers and pesticides used. The (Multi-) irrigation can be largely automated. Smaller Wasserzuläufe per area and more accurate dosing lead to low seepage and controlled Anfeuchtungstiefe. This will Versalzungsgefahr by capillary suction and Überwässerung reduced. Because of the irrigation water is not sent directly to the ground, but on the stock verregnet, is determined by high evaporative Interzeptionsverluste and a relatively low efficiency of water use from 65 to 75%. In addition to uneven distribution of water and wind along the edges of the fields. In addition to the high investment costs make spare parts store, a large energy demand and high operating, maintenance and renewal costs huge investments required. Likewise, a certain degree of training staff to use the repair and maintenance of irrigation facilities provided. The irrigation systems were initially for supplementary irrigation in humid climate area. Today in these regions from 50 to 90% of the irrigation area beregnet. Transition from the river for irrigation practices in the culture of wheat ArizonaWegen the many advantages of the procedure is spreading increasingly in semi-arid areas and is located there, according to the dam and irrigation furrows, in third place. Irrigation using fixed installations [Edit] For fixed installations, both the pumping station, as well as the supply and sprinklers installed fixed lines. Often, the supply pipes laid underground, the method is suitable only for perennial crops such as fruits, as a laying of pipes with a high cost. Irrigation systems using teilortsfester [Edit] When the plants are teilortsfesten intake pumping station and fixed lines installed, which Regner lines but can move flexibly in stock. This includes procedures such as circular or irrigation systems, sprinklers in which a car on ropes, sprinklers or a sled on the water hose through the stock is withdrawn

More equipment and use Description
In order for the cross-field work necessary to achieve often have four-wheel drive tractors and at least two, often also four very large wheels with grobstolligen profile. The vehicle's steering is done with (electro) hydraulic support. Today's tractors are available for multiple uses in all its forms, as very small, especially in the mountains in the forestry or Serviced Alpine Pasture can be used for very small or large wine for farming in lowland areas. For optimal speed for the work to achieve, modern tractors often on a vielstufiges Last gearbox or a CVT. As additional equipment commonly used in tractors is a front loader, sometimes a rear loader appropriate. Larger tractors now mostly on a cabin with air conditioning and other vehicles to have technical features such as Einzelradbremse and differential locks. Special provide the Unimog, the device makers and the so-called Muli, which usually with a slightly longer wheelbase than other tractors are constructed. The device makers has forward before or on the sub-floor engine on a further production capacity for additional work machines (alternatively, a loading platform), while the Unimog and the Muli behind the driver's cabin, a transport area and are very geländegängig. The Muli, especially in western Austria, Switzerland and South Tyrol. Even the so-called tug-Trac (MB-Trac, Deutz INTRAC, JCB Fastrac), where the work further forward of the driver or the middle between the axles positioned, diverge from the conventional standard construction. Another small tractors simplified form is the hand tractors. The trend towards ever greater and heavier machines (higher tensile force), as a result of a higher soil compaction and thus lower revenues to the ground. This can with the raising ballonartigen low-pressure tires (Terra tyres), the vehicle weight and better distribute the low tire pressure also cause less ground pressure, or the use of twin tyres (assembly of a second, the actual full gear wheel of the tractor) tackled. Massey Ferguson 135 with Norwegian roll bar. Picture: K.A. Gallic Due to the increasing speeds of tractors (up to 80 km / h for JCB Fastrac) and the low attenuation of large tractor tire has a large part of today's tractors a suspension of at least the front axle. The front axle is usually by a hydraulic or pneumatic suspension system. Tractors with full suspension have been only slightly, although they advantages for driving comfort, driving safety and the protection of soil with it. The most frequent accidents involving tractors happen in mountainous areas from overturning. In Austria, they must therefore since 1960, in Germany since the early 1970s, with a roll bar equipped. In the course of increasingly überrollsichere booths were set up.

hydraluic systems
we have two main kinds of hydraulic systems
1- open center
2- closed center
open center consist of gear pump (continuasly work) to give lower prissure which easier to do the maintenance and more cheaper and higer in feul consumption
the closed center with piston pump . work when you need the pressure . and give higher pressure and less in fuel consumption . but more expensive and harder to make maintenance
