A hypothesis is developed regarding the improved use of the potential energy that leads to the development of a new economical hydraulic machine. A transmission of the new agricultural tractor that can use the much bigger share of the effective potential energy is conceived in rough principles. A portable flatbed improves the total efficiency. A comparable analysis on very different sloped terrains is presented to argue for the greater efficiency of the new machine. The yearly fuel quantity saving by using the new hydraulic machine on the sloping terrain with realistic topography is 36 % in comparison to the winch cart. Decisional limits about the minimum internal combustion engine power are discussed</dc:description><dc:description xml:lang="sl">Namen predstavljenega dela je najti in ovrednotiti možnosti za zmanjšanja porabe goriva in skrajšanje časa obdelave zelo strmih kmetijskih površin, ki se obdelujejo z vitelnimi stroji. Nasad na strmem terenu je razporejen v vrstah, ki so orientirane po strmini navzgor. Nasad se obdeluje z delovnimi priključki, ki so nameščeni na vozičku. Voziček je opremljen z motorjem, ki poganja zgolj priključke. Premikanje vozička navzgor in spuščanje ob vrstah nasada navzdol se izvaja z vrvjo vitla, ki je nameščen na vrhu terena in ga poganja drug motor. Pri tej tehnologiji obdelave se pojavlja več problemov. Sistem ne omogoča izkoriščanja potencialne energije, ki se neprestano spreminja zaradi pomikanja vozička gor in dol. Posledica je velika poraba goriva, ki je lahko celo do dvakrat večja kot pri kmetijskih traktorjih, ki delajo na ravnem. Voziček, ki je lahko opremljen le z enim priključkom, se mora dvakrat pomikati po isti poti, kar podvaja čas obdelave.
