Izingxenye zokuvuna ezihlanganisayo ziyizingxenye ezibalulekile ezisekela ukusebenza kahle, okuzinzile kanye nesikhathi eside kwawo wonke umshini. Ingxenye ngayinye idlala indima engenakushintshwa kuyo yonke inqubo yokuvuna, ukubhula, ukuhlanza nokuqoqwa kwamabele.

Izingxenye eziyinhloko zomshini wokuvuna ohlanganisayo zihlanganisa unhlokweni, i-cutter bar, ireli, isigubhu sokubhula, ipuleti le-concave, ifeni yokuhlanza, i-auger, iketango lokuthutha, i-bearing, i-hydraulic system, izingxenye zokudlulisela kanye nezinsimbi. Lezi zingxenye kufanele zibe namandla aphezulu, ukumelana nokugqoka nokuzinza ukuze zivumelane nomsebenzi wesikhathi eside wasensimini, indawo eyinkimbinkimbi kanye nezimo zezitshalo ezahlukene.

Izingxenye zokuvuna ezisezingeni eliphezulu zinganciphisa izinga lokuhluleka, zithuthukise ukusebenza kahle futhi zinciphise izindleko zokulungisa. Ukugqoka izingxenye ezinjengama-blades, amaketanga nama-bearings kudinga ukuhlolwa njalo nokushintshwa ukuze kuqinisekiswe ukuthi umshini usebenza kahle ngesikhathi sokuvuna. Izingxenye ezijwayelekile, ezinokwethenjelwa nezihambisana kahle zisiza isivuni esihlanganisa ukuzuza ukulahlekelwa okuphansi, ukusebenza kahle okuphezulu nokusebenza kwezinga eliphezulu.

Emkhiqizweni wesimanje wezolimo, izingxenye zokuvuna azizona nje izesekeli kodwa futhi ziyisiqinisekiso esibalulekile sokuvuna ukudla. Izingxenye ezinhle kakhulu zenza umshini ube namandla kakhulu, zisiza abalimi ukuthuthukisa ukukhiqiza, futhi zinikeze ukusekelwa okuqinile kwesimanje kwezolimo kanye nokuvikeleka kokudla.
