Ithiphu Lokulima Lomlimi, iphuzu lokulima, Ithiphu Lokulima Lensimbi Engagugi, Ithiphu Lokulima Lemishini Yezolimo

I-plowshare ibhekisela engxenyeni eyinhloko yensimbi yamathuluzi okulima endabuko enza umsebenzi wokulima inhlabathi. Yakhiwa i-plowshare (yokuphula inhlabathi) kanye ne-plowbody (yokujika inhlabathi), futhi idlala indima ebalulekile kwezolimo ngokuphula ungqimba lwenhlabathi nokujika inhlabathi.
Ezinsukwini zokuqala, imikhiqizo yayenziwe kakhulu ngensimbi ephothiwe (njengezigebengu zakudala kusukela ngawo-1970), enobuso obumnyama obumnyama. Umklamo wegebengu elingunxantathu wathuthukisa ukusebenza kahle kokuphula inhlabathi. Imikhiqizo yesimanje iye yathuthukiswa ukuze isebenzise izinto ze-alloy ezifana nensimbi ye-manganese (65Mn) kanye nensimbi ye-boron, enobunzima obungu-45-50 HRC ngemva kokwelashwa ngokushisa, okuthuthukisa kakhulu ukumelana nokuguguleka.
Igeja kanye nomzimba wegeja kusebenzisa isakhiwo esihlukile, okuvumela ukushintshwa okuzimele (njengochungechunge lwe-German Rabe SUPER). Ububanzi bokulima obulungisekayo bungamasentimitha angu-33-60, bufanele izinhlobo ezahlukene zenhlabathi, kufaka phakathi inhlabathi enesihlabathi esithambile kuya enhlabathini yobumba.
