Iqukethe idivayisi yokushayela, i-hopper, ipayipi elidlulisayo, i-auger, amathreyi, idivayisi yokuphakamisa ukumiswa, idivayisi yokulwa nokugwedla, kanye nenzwa yokuphakelayo. Umsebenzi oyinhloko wesistimu ukudlulisa okuphakelayo ku-hopper kuthreyi ngayinye ukuze kuqinisekiswe ukudla kwenyama yenyama futhi ulawule ngokuzenzakalelayo ukuvuleka/ukuvalwa kwenjini ngenzwa yeleveli yezinto ukuze izondle ngokuzenzakalelayo.
