WORK PRODUCTIVITY AND FUEL CONSUMPTION FOR THE ROW ROPES MULCHER LOTTI IT 26 A

Pri vinogradništvu Tement smo v letih 2013 in 2014 preizkušali vrvični mulčer Lotti IT 26 A na petih površinah, ki so se razlikovale po naklonih od 13 do 41 odstotkov. Namen naloge je bil ugotoviti delovno storilnost in s tem povezano porabo goriva. Naklon površin se je med najbolj položno in najbolj strmo razlikoval za 315 odstotkov, pri čemer se je poraba časa prehoda povečala samo za 12 odstotkov. Pri porabi goriva so se pokazale velike razlike, saj se je poraba povečala za 36 odstotkov. Ugotovili smo, da sta poraba goriva in delovna storilnost najbolj enakomerni na površinah do 31 odstotkov nagiba. At the winery Tement we tested the row ropes mulcher Lotti IT 26 A throughout the years 2013 and 2014 on five different sloping areas, sloping from 13% up to 41%. The scope of this paper is to examine the work productivity and fuel consumption of the mulcher. The difference between the least steep slope and the steepest slope was 315 %, at which the elapsed time was only 12% longer between those slope runs. The fuel consumption was considerately larger in comparison, 36 %. We observed the optimum equal ratio of work productivity and fuel consumption at a slope of 31 %.
