Masefa emichina yekurima chinhu chakakosha pamidziyo yemazuva ano yekurima. Basa ravo rekutanga ndere kusefa tsvina kubva muinjini, hydraulic system, uye mhepo system, kuve nechokwadi chekuita kwakagadzikana munzvimbo dzakaoma dzekushanda. Nekuwedzera kwemakanika kwekurima, mhando yemafirita inokanganisa zvakananga hupenyu hwesevhisi, kushanda zvakanaka kwemafuta, uye kuvimbika kwekushanda kwemichina yekurima.
Mafirita emuchina wekurima akakamurwa muzvikamu zvitatu: mafirita emhepo, mafirita emafuta, uye mafirita emafuta ehydraulic. Mafirita emhepo anobvisa huruva uye zvinhu kubva mumhepo inopinda muinjini, kudzivirira kupera kwecylinder uye kuwedzera hupenyu hweinjini. Mafirita emafuta anobvisa kusvibiswa uye mwando kubva mumafuta, kudzivirira kuvhara kwejekiseni uye kuve nechokwadi chekupisa. Mafirita emafuta eHydraulic anodzivirira iyo hydraulic system kubva mukusvibiswa, kuchengetedza yakagadzikana system kudzvanywa, uye nekuvandudza kushanda kwayo.
Mukugadzirwa kwekurima, michina yekurima inowanzoshanda muminda ine guruva kana nzvimbo dzevhu dzine jecha. Airborne particulate matter inogona kupinda nyore muinjini uye hydraulic masisitimu, zvichikonzera kuwedzera kupfeka uye kutadza. Naizvozvo, masefa epamusoro-anoshandisa masefa akawanda akaturikidzana, senge faibha dzekugadzira, activated carbon, kana zvinhu zvakakosha zvesefa yemapepa, kunatsiridza kusefa uye kuwedzera nguva dzekutsiva. Pamusoro pezvo, mamwe masefa epamusoro anoratidza-mabasa ekuzvichenesa kana zviratidzo zvekudzvanyirira kuti zvigadzirise zviri nyore.
Kusarudza sefa yakakodzera kwakakosha pakugadzirisa michina yekurima. Masefa asina kunaka{{1} anogona kukonzera kusefa kusina kukwana, kumhanyisa kusakara nekubvaruka kwemichina, uye kuwedzera mari dzekugadzirisa. Naizvozvo, varimi nevanoshandisa michina yekurima vanofanira kukoshesa masefa kubva kumhando dzechokwadi kana dzakasimbiswa votsiva nguva nenguva zvichienderana negwaro. Pamusoro pezvo, ivo vanofanirwa kugara vachiongorora uye nekukasira kugadzirisa chero akavharika kana akakuvadzwa mafirita zvinhu kuti vaone kuti michina yekurima inogara iri muchimiro chekushanda.
Muchidimbu, kunyange ichiita seisina kukosha, mafirita emuchina wekurima akakosha kuitira kuti ive nechokwadi chekushanda kwakanaka uye kwakachengeteka. Kusarudzwa kwesefa nemagadzirirwo akafanira hakungonatsiridza kurima kwakanaka chete asiwo kunoderedza-mitengo yenguva refu, zvichipa tsigiro yakasimba yebudiriro yezvekurima zvechizvino-zvino.
