He pito koko wetewete hōhonu me te poraka waro, he ātete ki te kakahu me te kore e paheke, he wāhanga ngoikore mō ngā mīhini ahuwhenua me ngā taputapu parau whenua.
I tēnei rāngai ahuwhenua e tere haere ana te whakamahi mīhini, ko te pakari o ngā wāhanga mīhini ahuwhenua te mea e whakatau tika ana i te pai o te whakaputa me te utu. I roto i ēnei, ko ngā pito koko carbide, hei wāhanga matua mō ngā taputapu pēnei i ngā mīhini oneone me ngā mīhini keri, kei te noho hei otinga pai mō ngā kaimahi pāmu me ngā pāmu nui nā te mea he pai ake te mahi.
He ngāwari te pakaru me te ngatata o ngā pito o te koko maitai tuku iho ina mahi ana i roto i ngā āhuatanga uaua pēnei i te oneone kohatu me te uku taumaha, e hiahia ana kia whakakapia pinepine, ā, ka hua ake he hohonutanga parau kore, ka iti ake te pai o te mahi. Mā te taenga mai o ngā pito o te koko kāpia ka ea katoa tēnei raruraru. He mea hanga te nuinga ki te maitai whakarewa kaha-teitei, ātete-paowa, me ngā poraka kāpia e rua kua whakauruhia ki roto i te pito, ka tutuki he taurite tino pai i waenga i te pakeke me te pakari—ka mau tonu te ātete pānga o te maitai whakarewa me te whakanui ake i te ātete pao i roto i te paparanga kāpia. I roto i ngā taiao parau uaua, he nui ake te roa o tōna mahi i ngā pito o te koko noa.
Haunga ngā whakapainga ki ngā rauemi matua, kei roto hoki i te hoahoa hanganga o te pito o te koko ngā āhuatanga atamai. Mā te kakano ārai-paheke āhua-V i runga i te mata ka mau te oneone i te wā e whakamahia ana, ka ārai i te paheke me te whakarite i te hohonutanga parau whenua pumau me te ōrite. Mā ngā kōhao pūtu paerewa kua keria i mua ka whai hua, ka watea hoki te tāutanga me te whakakapinga, ka taea ai te hototahi tika ki ngā mīhini parau whenua rongonui me te kore he whakarerekētanga tāpiri, ka whakaiti nui i te wā kore mahi mō te tiaki. I te wā kotahi, ka whakarei ake te paninga ārai-waikura pango i te ātete ki te waikura, ka whakarite kia mau tonu te mahi pumau o te pito o te koko ahakoa i roto i ngā mahi o waho mō te wā roa.
Mō te mahi ahuwhenua nui, ko te whiriwhiri i te pito koko waro he tikanga kia iti ake ngā utu katoa: kia iti ake te auau o te whakakapinga wāhanga, kia iti ake te ngaronga o te mahi me te wā kore mahi, me te whakarite hoki i te kounga o te whakatipu me te whakatakoto i te turanga pai mō te tipu o muri mai. Ahakoa te wawahi i te oneone, te parau hohonu, te tango otaota rānei, ka tukuna e tēnei pito koko he mahi pumau me te pono, e āwhina ana ki te whakapai ake i te kounga me te whai huatanga o te mahi ahuwhenua.
I te anga whakamua o te mahi mīhini ahuwhenua ki te whai huatanga me te penapena pūngao, ehara i te mea he whakapai ake noa iho ngā pito o te koko waro i ngā taputapu tāpiri, engari he taahiraa matua anō hoki ki te whakatairanga i te arotautanga o ngā tauira whakaputa ahuwhenua, kia pai ake ai, kia pumau ake ai hoki ia mahi parau whenua.
