Amalungu etrektara ngamacandelo abalulekileyo aqinisekisa ukuba iitrektara zisebenza ngokuthembekileyo, ngamandla nangokufanelekileyo kuzo zonke iintlobo zomsebenzi wasefama. Iitrektara zisebenza njengamandla angundoqo kulimo lwangoku, kwaye imeko yazo yesiqhelo yokusebenza ixhomekeke ngokupheleleyo kumgangatho kunye nokutshatisa inxalenye nganye echanekileyo.

Iindawo eziphambili zetrektara ziquka inkqubo ye-injini, i-clutch, i-gearbox, i-shaft yokuqhuba, ii-asi zangaphambili nezingasemva, i-hydraulic system, i-PTO shaft, iibheringi, izihluzo, amatayara, irediyetha, izitywini kunye neendawo zokuqhagamshela. Icandelo ngalinye lenza imisebenzi ebalulekileyo efana nokuphuma kwamandla, ukutshintsha kwesantya, ukuqhubela phambili, ukuqhokra nokuqhuba.

Amalungu etrektara akumgangatho ophezulu aqhele ukwenziwa ngezinto ezinokuqina okuphezulu kunye nezixhobo zokunxiba, ezinozinzo olomeleleyo kunye nobomi obude benkonzo. Bangakwazi ukuziqhelanisa neendawo zokusebenza ezinzima ezifana nomhlaba olinywayo, ukuhlwayela, ukuthuthwa nokunkcenkceshela, ukunciphisa ukungaphumeleli kwixesha elixakekileyo lokulima kunye neendleko eziphantsi zokugcinwa.

Ukunxiba iinxalenye ezifana nezihluzi, amabhanti, izitywina zeoli kunye neebheringi zifuna ukuhlolwa rhoqo kunye nokutshintshwa. Iinxalenye zetrektara ezisemgangathweni nezithembekileyo zinokuphucula ukusebenza kakuhle, ukwandisa ubomi boomatshini kunye nokuqinisekisa inkqubela phambili egudileyo yemveliso yezolimo.

Kuphuhliso lwangoku lwezolimo, iinxalenye zetrektara zisisiqinisekiso esibalulekileyo samandla ezolimo. Baxhasa zonke iintlobo zokusebenza koomatshini basefama, banceda ukuphucula imveliso, ukunciphisa umsebenzi wamafama kunye nokubonelela ngenkxaso eqinile kwimveliso yokutya kunye nophuhliso lwasemaphandleni.
