Iigiya zothumelo lwezobuNjineli obuchanekileyo obuphezulu, ukucwangciswa kokusila ukuveliswa kwezixhobo ze-bevel ezithe ngqo kwezolimo, iPhilippine Agricultural Engineering Standards PAES 308:2001 ibonelela ngeenkcukacha zokusetyenziswa kweiigiya ze-bevel ezithe ngqokoomatshini bezolimo, kugxininiswa kumanyathelo okhuseleko afana nokuvala uqhubo olunamaqweqwe kunye nokuhlolwa ngamaxesha athile1.
Ezi giya zithandwa ngokusebenza kwazo okuphezulu ngenxa yokuqhelaniswa kwamazinyo azo kwicala lentshukumo, enciphisa ilahleko yokutyibilika24. Inkqubo yokwenziwa kwemveliso ilula, nto leyo ekhokelela ekuthotyweni kweendleko zemveliso kwaye izenze zilungele imveliso eninzi24. Ummandla wabo omkhulu woqhagamshelwano phakathi kwamazinyo uqinisekisa umthamo omhle wokuthwala umthwalo kunye nokumelana nokukhathala, okufaka isandla ekuthembekeni kwabo kunye nokuqina24.
Ngqobizixhobo evelsukufumana ukusetyenziswa kwizixhobo ezahlukeneyo zezolimo, kubandakanywa oomatshini bokucheba izithole, apho bayinxalenye yesixhobo sokuqhuba isenzo sokunciphisa24. Zinezinto ezininzi kwaye zinokuhlengahlengiswa kwimisebenzi emininzi koomatshini bezolimo, njengokutyala, ukuchumisa, ukuhlakula, kunye nokuvuna xa zidityaniswe nezinto ezincamatheleyo ezahlukeneyo24. Ngaphaya kwezolimo, zikwasetyenziswa kwizixhobo zokwakha, iinkqubo zothumelo lweemoto, kunye nezinye izicelo zefektri apho ukuhanjiswa kwamandla okuthembekileyo nokusebenzayo kubalulekile23.
Ukwenza iigiya ze-bevel ezithe tye bubuchule obuchanekileyo obuphakamisa amandla kunye nokuqina kwazo, zizenze zilungele iimeko ezinzima ezihlala zidibana nezolimo3. Iitrektara ezineegiya zebevel ezibunjiweyo zingenza uluhlu olubanzi lwemisebenzi, zibonisa ukuguquguquka kwazo kwiindlela zokulima zanamhlanje3. Njengoko ishishini lezolimo lihambela phambili, uphuhliso lobuchule bokwenza kunye nobuchwepheshe bezixhobo luya kuqhubeka ukudlala indima ebalulekileyo ekubumbeni isizukulwana esilandelayo seetrektara ezisebenza kakhulu3.
