Le spiralizixhobo ze-beveliseti yayisetyenziswa kwitrektara. Kwitrektara ibekwe phambi kwevili lokuqhuba nasemva kwe gearbox . Zonke iindlela zothumelo kunye neegobolondo zibizwa ngokuba yi-axle yangasemva, kwaye umsebenzi wayo oyintloko kukunyuka, ukwandisa, ukuncipha kunye nokutshintsha i-torque .Ukongezelela kwiitrektara ezineenjini ezinqamlezayo ezisebenzisa i-cylindrical gear pairs as central transmission, uninzi lwazo zisebenzisa i-bevel gear pairs, ezingagcini nje ukwandisa i-torque kunye nokunciphisa isantya, kodwa ziphinde zitshintshe ukuhanjiswa kwe-torque.
