The paper explains the functionig principle of special construction (selfoutflnking)
rotofrazer with vertical rotor, joint conection of rotor for self-outflanking
machin, its application possibilities and the advantages over the oders working devices
of tractor attachments that have been used so far for digging the soil under fruit trees in
the rows where the moment of resistance of stalk is greater than the moment of
resistance of the surrounding.U radu je prikazan princip funkcionisanja specijalne konstrukcije (samoobilazeće)
rotofreze sa vertikalnim rotorom, zglobna veza rotora za otklanjanje oruđa,
mogućnosti primene, prednosti u odnosu na druge tipove primenjivanih radnih organa na
traktorskim priključnim mašinama za obradu zemljišta u redu zasada i čiji otporni
momenat stabla je veći od otpornog momenta stabla korova koji raste u njegovoj okolini
