Ngā taputapu mīhini ahuwhenua, te parau hurihuri, te whakaritenga mata piko, ngā tauira mata parau hurihuri
Ko te mata parau hurihuri te wāhanga matua o te mīhini parau hurihuri e whakahaerehia ana e te tarakihana, e tapahi ana, e kuru ana, e huri ana hoki i te oneone pāmu mā te whakakotahitanga o te nekehanga hurihuri o te kakau mata me te nekehanga whakamua o te waeine. Hei tētahi o ngā wāhanga tino ngoikore i roto i te mahi ahuwhenua, ka pā tika te hoahoa o ngā mata parau hurihuri ki te whakapaunga pūngao, te kounga o te oneone, me te maeneene o te whenua o te mahi katoa a te mīhini.
E ai ki te taiao mahi me ngā whakaritenga mahi, ka wehea ngā maripi parau hurihuri ki ngā momo penei i ngā maripi piko, ngā maripi whao, ngā maripi koki matau, me ngā maripi piko. I roto i ēnei, he taha piko te mata o te mata piko me te mahi tapahi reti, kia iti ake ai te tūponotanga ki te mau i te tarutaru, ā, he whānui te whakamahinga i roto i ngā pāmu raihi me ngā mahi whakahoki kakau witi. He kaha te kaha o te maripi whao ki te uru ki te oneone, ā, he pai mō te whakatipu māra huawhenua me ngā marae he iti ake te taru. I ngā tau tata nei, kua hangaia ngā parau hurihuri parirau takirua, kotahi te kakau, he āhua-Y, me ngā pereti parirau maui me te matau pumau āhua-Y, me ngā āhua marama piko.
Ehara i te mea ka taea e rātou te huri me te tapahi i te kakau pakiaka ki raro ki te paparanga o raro o te paru anake, engari he maha hoki ā rātou mahi pēnei i te kuru oneone, te hiki i te paru, me te whakataurite. He māmā te hanganga, ā, he iti te utu. Hei tāpiri, hei whakahaere i ngā whenua kakau witi teitei, he maha ngā wā ka whakauruhia te parau hurihuri tapahi kakau witi ki te huinga o ngā mata poto āhua-L me ngā mata piko raupapa IT hei whakatutuki i te mahi paparanga tuaka rua.
Ko ngā mīhini hurihanga kounga teitei e whakamahi ana i te maitai puna 65Mn, 60Si2Mn rānei hei rauemi mata. Neke atu i te tekau ngā tukanga e hiahiatia ana mō tōna hanga, tae atu ki te tapahi, te whakamahana, te hurihuri, te hanga, te wero me te tapahi kokonga, te whakamahana, me te pupuhi pupuhi. Ko te hangarau whakamahana matatau me te hangarau whakamahana ātete-kakahu ka taea e te mata te pakeke me te ātete-kakahu, engari ka mau tonu te mata koi i a ia e huri ana, ā, ka whakaitihia te ātete ki te parau me te whakapaunga wahie. Ka taea e te roanga mahi te eke ki te 2 ki te 4 ngā wā i ngā taputapu tapahi noa.
Kei te kaha haere te hoahoa o ngā mīhini huri whenua hou ki te whakanui i te maha o ngā mahi me te urutau. Ehara i te mea ka taea anake te whakaoti i ngā mahi kuru oneone taketake, engari ka taea hoki te karo i te hononga o te kakau witi me te whakapai ake i te ngāwari o te haere mā te tāpiri i ngā taputapu ārai hononga, te arotau rānei i te piko o te mata (pēnei i te porowhita piko R120mm). Ka tapahia, ka whiua te oneone e te taha porowhita, piko rānei o te mīhini huri whenua i te tere tere, ā, mā te āwhina o te taupoki me te wakatō, ka tutuki te kuru oneone tuarua, ka papatahi te mata, ka whakaranua te tongi oneone kia ōrite i muri i te mahi.
