Gawo lothandizira la makina a ulimi ndi gawo lofunika kwambiri logwirira ntchito m'nthaka lomwe limapangidwa kuti ligwirizane ndi mapulawo a bolodi, omwe nthawi zambiri amapangidwa kapena kusindikizidwa ndi chitsulo cha boron chosatha kutha kapena chitsulo cha manganese cha 65Mn. Mphepete mwake mwapamwamba mumalandira chithandizo chapadera cha kutentha, kukhala olimba kwambiri komanso osagwirizana ndi kutha, zomwe zimathandiza kuti nthaka ilowe mosavuta komanso kudula bwino udzu ndi zotsalira za mbewu. Chogulitsachi chili ndi mphamvu zambiri, kulimba kwambiri, kusinthasintha kwa nthaka komanso kuphimba bwino, komanso kukana kochepa, zomwe zimapangitsa kuti chikhale choyenera kulima m'malo ouma. Chimachepetsa bwino kukana kulima pamene chikuwonjezera magwiridwe antchito komanso kugawikana kwa nthaka.

Chomera cholima (chomwe chimadziwikanso kuti tsamba la pulawo) ndiye gawo lofunikira kwambiri pakulima kwa pulawo, lomwe limayikidwa kutsogolo kwa thupi lalikulu la pulawo. Chimagwira ntchito zofunika kwambiri monga kulowa m'nthaka, kudula, ndi kutsogolera. Monga gawo loyamba lomwe limakhudzana mwachindunji ndi nthaka, magwiridwe ake amakhudza mwachindunji ubwino wa ntchito, mphamvu zomwe zimagwiritsidwa ntchito, komanso nthawi yomwe makina onse olima amagwirira ntchito.

Kuchokera pa kapangidwe ka ntchito, ntchito ya pulawo ndi yofunika kwambiri.

Pochita homuweki, fosholo ya pulawo imalowa m'nthaka mopingasa, kudula gawo la pansi la nthaka, ndikutsogolera nthaka kukhoma la pulawo kuti iphwanyidwe ndi kutembenuzidwe. Kuti igwirizane ndi mikhalidwe yosiyanasiyana ya nthaka ndi zosowa za ulimi, mapulawo ndi mafosholo amagawidwa m'mitundu yosiyanasiyana ya kapangidwe kake, makamaka kuphatikiza mapulawo a trapezoidal omwe amagwiritsidwa ntchito polima nthawi zonse, mapulawo odulidwa oyenera nthaka yolimba, ndi mapulawo amakona atatu omwe amagwiritsidwa ntchito pokonzanso nthaka.

Ponena za zipangizo ndi luso lapamwamba, mapulawu apamwamba nthawi zambiri amapangidwa ndi chitsulo champhamvu kwambiri, monga 65Mn, 60Si2Mn, ndi zipangizo zina. Pakupanga, opanga apamwamba adzagwiritsa ntchito ukadaulo wopanga ndikugwiritsa ntchito makina akuluakulu opangira matani kuti asunge umphumphu wa kapangidwe ka ulusi wachitsulo, motero kumawonjezera kwambiri kukana kwa mphamvu ndi kukana kuwonongeka kwa chinthucho.

Pambuyo popangira, chinthucho chiyeneranso kuchitidwa opaleshoni yolondola yotenthetsera kuti chikhale cholimba cha HRC 38-50. Ngakhale kuti chimaonetsetsa kuti chili cholimba mokwanira, chilinso ndi mphamvu yabwino yopewera kusweka kwa brittle fracture.

Pofuna kukulitsa nthawi yake yogwira ntchito, mapulawu ndi mafosholo amakono amagwiritsa ntchito mfundo zosiyanasiyana zosatha mu kapangidwe kawo. Mwachitsanzo, kugwiritsa ntchito kapangidwe kowonjezera komweko kuti asonkhanitse zinthu zosatha m'malo omwe amawonongeka kwambiri (monga nsonga za fosholo); Zinthu zina zimathandizanso kutembenuza kuti zigwiritsidwe ntchito. Mbali imodzi ikatha, imatha kuzunguliridwa ndikuyikidwa kuti ipitirize kugwiritsa ntchito nsonga inayo, kuwirikiza kawiri nthawi yake yogwira ntchito.
