One of the technical factors from agricultural nozzles and overall plant protection is droplet diameter, which exclusively depends on working pressure, ISO number and nozzle type. Therefore, this paper was aimed to describe mathematical...

This paper presents the tests results of three types of hay mowing machines (later in text: mowers), namely a self-propelled oscillatory mower-conditioner and two tractor-mounted mowers with oscillatory and rotary blades, used to mow...

The paper presents the three years efficiency results (2011-2013) of the work and ways of harvesting (three types of mowers, with or without spreading the forage) influencing the quality of the forage (the content of crude protein and crude fiber) during the three days drying process. These results indicate that the harvesting method can strongly affect the work efficiency, energy consumption, the forage drying intensity and the quality of forage used for hay and haylage preparation. The best quality of the forage was achieved when a drum rotating mower PÖTTINGER CAT 185 was used. Negative correlation was found between content of crude protein and the crude fibre content, depending on the type of mower, varying in the range between r= -0.978 and r= -0.882 (PÖTTINGER CAT 185 r= -0.882 P≤0.05 to JF STOLL SB 200 r= -0.978 P≤0.001).

Mnoštvo pročistačkih sustava do sada je načinjeno s uporabom različitih granulacija perlita. Raspodjela veličina čestica perlita izravno utječe na svojstva retencije pročistačkih medija. Informacije o raspodjeli veličine...

The article is focused on the behaviour of the basic properties of dairy cow's solid manure over the maturation period. The manure was exposed to mechanized aerobic processing by mechanically turning-over. Performed analysis comprehended measurements...

With an extremely carefully and very dedicated approach, power transmission may, but not obligatory, present a serious technical, environmental or econometric problem. In agricultural engineering, this process is unfortunately often further complicated. Therefore, energy transfer in this particularly sensitive area must be performed with special care, and energy-specific technical solutions must be applied in each isolated case. These solutions must be specially harmonized with the dynamic energy needs of the system, and should provide energy transfer that is technically, technologically, economically and ecologically harmonized with the practically unpredictable dynamic needs of hydraulic elements and systems in agricultural engineering. However, the use of hydraulic drive, or at least its participation in power transmission, has become an almost inevitable practice today. This is especially important if it is also electronically controlled, because with a number of additional advantages including fluid line flexibility, energy transfer from arbitrary types of primary sources and energy converters, all the way to the appropriate control units or consumers can be achieved successfully, efficiently and accurately.
