I-plowshare yangaphambili, iinombolo zenxalenye 073250 kunye no-073251, oomatshini bezolimo.
Iiplanga zangaphambili 073250 kunye no-073251 zizinto eziphambili, eziguga lula kumatshini wokulima wezolimo, ingakumbi iiplanga zebhodi yokubumba kunye neeplanga eziguqukayo ngesantya esiphezulu. Njengenxalenye ephambili yokuhlanganiswa kweplanga, olu luhlu lweeplanga zangaphambili luhlala lusebenza kunye neplanga langasemva, iplanga, kunye nekholamu yeplanga yokusika, ukuqhekeza, kunye nokujika umhlaba. Ezi modeli zimbini zibonisa uyilo olwahlulweyo, oluyilelwe ukujongana neendleko eziphezulu zokutshintshwa kunye nokugcinwa okungahambi kakuhle okunxulunyaniswa neeplanga zemveli zeqhekeza elinye emva kokuguguleka okuncinci. Zifanelekile ngokukodwa kwiindawo zokulima ezikhawulezayo kunye neendawo zokusebenza ezinzima kumhlaba owomileyo.
Iiplanga zangaphambili 073250 kunye no-073251, ezikwindawo engaphezulu nangasemva kweplanga, zezona ndawo ziphambili ezithwala ubunzima bokungqubana komhlaba kunye nefuthe. Imisebenzi yazo ephambili yile:
Ukuncedisa ekungeneni nasekuqhekekeni komhlaba: Xa besebenza kunye ne-plowshare, bayacinezela baze baqhekeze amagada asikiweyo yi-plowshare, benciphisa umthwalo womsebenzi kwiindawo ezilandelayo.
Ukujika nokugquma: Ngokusebenzisa umphezulu othile ogobileyo, ziyawuphakamisa umhlaba oqhekekileyo zize ziwuphakamise ngokuthe ngcembe, ziwugqume nzulu umququ, ukhula, kunye nesichumisi, nto leyo ephucula ulwakhiwo lomhlaba.
Ulwakhiwo lwemodyuli oluhlukanisiweyo: Lusebenzisa iibholithi ezifakwe ecaleni ukulungisa i-plowshare (okanye ikholamu yokulima) ukuze kube lula ukuhlanganisa nokuchitha. Ekubeni i-plowshare engaphambili iguga ngokukhawuleza kune-plowshare engasemva ngexesha lokuhlakula, olu yilo oluhlukanisiweyo luvumela abasebenzisi ukuba batshintshe kuphela i-plowshare engaphambili egugile kakhulu (njenge-073250 okanye i-073251) ngelixa begcina i-plowshare engasemva ekwimeko entle kunye nezinye izinto, ngaloo ndlela kunciphisa kakhulu iindleko zokulungisa kunye nexesha lokungasebenzi.
Ukuze kujongwane nokukrazuka komhlaba okunamandla kunye neendawo ezixineneyo, iiplanga zangaphambili zeemodeli 073250 kunye no-073251 zihlala zenziwe kusetyenziswa izixhobo ezinobunzima obuphezulu, ukumelana nokuguguleka okuphezulu, kunye nokuqina okuhle. Ngokuhambelana netekhnoloji yanamhlanje yoomatshini bezolimo, ezi zinto zihlala zenziwe ngentsimbi ekumgangatho ophezulu (njengentsimbi ye-manganese engama-65Mn) ngonyango lobushushu okanye iinkqubo zokuqinisa umphezulu ukuqinisekisa ubomi benkonzo ende. Ezinye iindlela zoyilo eziphezulu zinokubandakanya izixhobo zemagnethi okanye ukulungiswa okukhethekileyo komphezulu (njengee-concave composite curve shin blades) ukunciphisa ngakumbi ukumelana nokulima, ukunciphisa ukusetyenziswa kwepetroli, kunye nokuphucula ukusebenza kokuphosa umhlaba phantsi kokusebenza ngesantya esiphezulu.
Olu luhlu lwee-plowshare zangaphambili lusetyenziswa kakhulu kwii-moldboard plows ezixhonyiweyo, ii-plow eziguqukayo ezikhawulezayo, kunye nezinye izixhobo ezineetrektara ezinkulu neziphakathi. Nokuba zisetyenziselwa ukulima nzulu ekwindla, ukulima entwasahlobo, okanye imisebenzi yokususa iingca kwimihlaba enzima yodongwe, imihlaba emnyama, okanye amasimi omileyo ngokubanzi, iimodeli ze-073250 kunye ne-073251, ezinoyilo lwazo oluhle kakhulu lomphezulu ogobileyo, ziqinisekisa ukuhamba kakuhle kunye nomgangatho wokulima, nto leyo ezenza zibe ziindawo ezifanelekileyo zokutshintsha ukuze kufezekiswe "ukulima ngendlela yokugcina izinto" kunye nezolimo ezisebenzayo.
