Nsonga ya chogwirira chozungulira, Fosholo ya subsoiler, Gawo la pulawo la famu, Tsamba lothira losawonongeka, Tsamba lokwezera mabowo apakati
Uwu ndi tsamba lolimba la ulimi lomwe lapangidwa kuti ligwire bwino nthaka.
Yokhala ndi kapangidwe kakuthwa, kolunjika kokhala ndi mipata yolimbitsa yofanana ndi V pamwamba,
Zimathandiza kwambiri kudula bwino komanso kukana kuvala.
Yokhala ndi mabowo awiri omangira (limodzi pamwamba ndi lina pakati),
Tsamba limatsimikizira kuti limakhala lokhazikika komanso lotetezeka panthawi yogwira ntchito.
Yopangidwa ndi chitsulo champhamvu kwambiri chothira kutentha ndi utoto wakuda woletsa dzimbiri,
Ili ndi kuuma kwakukulu, kukana kugunda kwambiri, komanso kukana dzimbiri bwino,
kuonetsetsa kuti ntchitoyo ikhala yayitali ngakhale m'mikhalidwe yovuta.
Kupatula kukweza zinthu zofunika kwambiri, kapangidwe ka nsonga ya fosholo kalinso ndi zinthu zanzeru. Kapangidwe ka V kosakhala ndi kutsetsereka pamwamba kamatsimikizira kugwira bwino nthaka panthawi yogwira ntchito, kupewa kutsetsereka ndikuwonetsetsa kuti nthaka ikugwira bwino komanso mofanana. Mabowo okhazikika obowoledwa kale amapangitsa kuti kuyika ndi kusintha zinthu kukhale kothandiza komanso kosavuta, zomwe zimathandiza kuti makina olima amitundu yosiyanasiyana azigwirizana popanda kusintha kwina, zomwe zimachepetsa kwambiri nthawi yogwira ntchito yokonza. Nthawi yomweyo, utoto wakuda woletsa dzimbiri umawonjezera kukana dzimbiri, ndikuwonetsetsa kuti nsonga ya fosholo imasunga magwiridwe antchito okhazikika ngakhale pa ntchito zakunja kwa nthawi yayitali.
Pa ulimi waukulu, kusankha nsonga ya fosholo ya carbide kumatanthauza kuchepetsa ndalama zonse: kuchepetsa kuchuluka kwa zinthu zomwe zasinthidwa, kuchepetsa kutayika kwa antchito ndi nthawi yopuma, pamene kuonetsetsa kuti ulimi ndi wabwino komanso kukhazikitsa maziko abwino a kukula kwa mbewu pambuyo pake. Kaya ndi kudula nthaka, kulima mozama, kapena kupalira udzu, nsonga ya fosholo iyi imapereka ntchito yokhazikika komanso yodalirika, kuthandiza kukonza ubwino ndi magwiridwe antchito a ulimi.
Pamene makina a ulimi akupita patsogolo kwambiri komanso kusunga mphamvu, nsonga za carbide fosholo sizimangowonjezera zowonjezera zokha, komanso ndi gawo lofunika kwambiri pakulimbikitsa kukonza bwino mitundu yopanga ulimi, zomwe zimapangitsa kuti ntchito iliyonse yolima ikhale yogwira mtima komanso yokhazikika.
