O vaega ta'avale o vaega fa'avae ia e fa'amautinoa ai e mafai ona fa'agaioi lelei, mamana ma lelei palau i so'o se galuega fa'ato'aga. Tractors e avea ma malosiaga autu i faʻatoʻaga faʻaonaponei, ma o latou tulaga masani galue e faʻalagolago atoa i le lelei ma le fetaui o vaega taʻitasi.

Vaega ta'avale autu e aofia ai le afi afi, pipii, gearbox, ave taavale, axles luma ma tua, hydraulic system, PTO shaft, bearings, faamama, pa'u, radiator, faamaufaailoga ma vaega fesootai. O vaega ta'itasi o lo'o fa'atinoina galuega taua e pei o le fa'aogaina o le eletise, suiga o le saoasaoa, ta'avale, taofi ma le ta'avale.

O vaega taʻavale sili ona lelei e masani lava ona faia i mea maualuga ma faʻaofuofu, faʻatasi ai ma le mautu malosi ma le umi o le auaunaga. E mafai ona latou fa'afetaui i si'osi'omaga lavelave galue e pei o fanua fa'ato'aga, lulu, felauaiga ma fa'asūsū, fa'aitiitia fa'aletonu i vaitau pisi o fa'ato'aga ma fa'aitiitia tau fa'aleleia.

O le ofuina o vaega e pei o faamama, fusipaʻu, faʻamaufaʻailoga suauʻu ma bearings e manaʻomia le asiasia masani ma toe sui. O vaega taʻavale masani ma faʻatuatuaina e mafai ona faʻaleleia le lelei o galuega, faʻalautele le ola o le masini ma faʻamautinoa le alualu i luma o le gaosiga o faʻatoʻaga.

I le atina'eina o fa'ato'aga fa'aonaponei, o vaega ta'avale o se fa'amaoniga taua o le malosi fa'ato'aga. Latou te lagolagoina ituaiga uma o masini faʻatoʻaga, fesoasoani e faʻaleleia le gaosiga, faʻaitiitia galuega a le au faifaatoaga ma tuʻuina atu le lagolago malosi mo le gaosiga o meaʻai ma atinaʻe i nuʻu i tua.
