Ngā mōhiohio hua.

(1) Kotahi te wahi, kāore he whakarewa

(2) Te Hanga, Te Manawanui Nui hei Ārai i ngā Pakaru

(3)Ko tētahi o ngā mea tino noa, kaha, pakari, whai hua, e whakamahia whānuitia ana hei wetewete i te toka.

Ngā Hoahoa o te Rakau

Ko ngā kakau parapara (pikitia 4a) te mea iti rawa te kaha e hiahiatia ana hei kukume. I ētahi mahi ngahere, ka taea e ngā kakau parapara te hiki i te nui rawa o ngā tumu me ngā toka, te whakararuraru i ngā rauemi mata, te whakaatu rānei i te nui o te oneone o raro. Ka panaia e ngā kakau swept ngā rauemi ki roto i te oneone, ka tapahia. Ka āwhina pea rātou ki te ārai i te puru o te oneone, inā koa i roto i ngā rakau, ngā tumu, me ngā tapahi. Ko ngā kakau tika, āhua "L" rānei, he āhuatanga kei waenganui i ngā kakau parapara me ngā kakau swept.

Pikitia 4a—Ko ngā hoahoa kakau ko: te āhua whiti, te āhua tika, te āhua "L" rānei, te āhua haurua-parabolic,
me te parabolic. Ka pā te hoahoa o te kakau ki te mahi o te oneone raro, te kaha o te kakau,
te whakararuraru o te mata me te toenga, te whai huatanga o te pakaru o te oneone, me te
te hōpaika e hiahiatia ana hei kukume i te oneone o raro.

Me hanga ngā kakau kia taea te pupuri i ngā toka, ngā pakiaka nunui, me ngā oneone tino kikī.

Ko te matotoru o ngā kakau he ¾ ki te 1½ inihi. He pai ngā kakau angiangi mō te mahi ahuwhenua. He pai ake te mau o ngā kakau matotoru i ngā āhuatanga toka, engari me nui ake, me kaha ake ngā taputapu hei kukume i a rātou, hei whakakorikori hoki i te mata. Ko ngā kakau piko, pērā i ngā mea e kitea ana i runga i ngā oneone o raro o Paratill, he piko taha (pikitia 4b). Kua whakaatuhia e ētahi whakamātautau he iti ake te whakakorikori o ngā kakau piko i ngā toenga mata i ngā kakau tika.

Ko te tawhiti noa he 30 ki te 42 inihi i waenga i ngā kakau. Me tae ngā kakau ki te 1 ki te 2 inihi i raro i te paparanga hohonu rawa kua whakakīia.

Pikitia 4b—Te kakau piko.

Me whakarite te tawhiti me te teitei o ngā kakau i te mara. Me whai wira ine ngā waka keri oneone e tōia ana hei whakahaere i te hohonutanga o te kakau. He pai te mahi a ngā kakau ripper tuku iho, e kitea ana i runga i ngā taputapu dozer, ina tāpirihia he pito parirau, ā, he pai pea mō ngā mahi me ngā wāhi maha.
