Analiza različnih načinov košnje na domači kmetiji

Virant, Matej (author), Bernik, Rajko (mentor)

V diplomski nalogi smo izvedli poskus na domačem kmetijskem gospodarstvu. Primerjali smo tri glavne vrste traktorskih kosilnicah, ki se razlikujejo po principu delovanja, načinu vpetja, masi in potrebnih obratih za delovanje. Primerjali smo strižno kosilnico in diskasto ter bobensko rotacijsko kosilnico. Merili smo porabo plinskega olja, čas za košnjo in pripravo kosilnice. Za poizkus smo uporabili isti traktor in za košnjo uporabili na tretjine razdeljeno kmetijsko zemljišče v dejanski rabi kot trajno travinje. Priprava kosilnice na košnjo je trajala najdlje pri strižni kosilnici, najmanj pa pri bobenski rotacijski kosilnici. Poraba časa za košnjo s strižno kosilnico je najdaljša, najkrajša pa pri košnji z diskasto rotacijsko kosilnico. Največ plinskega olja smo porabili pri košnji z rotacijsko bobensko kosilnico, najmanj pa pri košnji s strižno kosilnico. Ugotovili smo linearno odvisnost porabe plinskega olja od mase kosilnice.

• Title: Comparison of main types of mowers on farmstead

Abstract

The aim of study was to analyse and compare three different principles of mowers on homestead. The mowers have different principle of working, type of detachment, mass and power take-off speed. We have tested finger blade, rotary disc and rotary drum mower. We have compared fuel consumption and measured time of mowing and preparing mowers for usage. Two fields were separated in three parts with equal area. With each mower we have mowed one part of both fields. As expected, rotary mowers had higher consumption of fuel. Meanwhile the lowest consumption of fuel had finger blade mower. Considering weight of mower, fuel consumption could be explained. On the other hand, finger blade mower needed more time for attachment and mowing, compared to any of rotary mowers.
