Njira ya rabara ndi mtundu watsopano wa kayendedwe ka chassis komwe kamagwiritsidwa ntchito pa ma excavator ang'onoang'ono ndi makina ena omangira apakatikati ndi akuluakulu.

Ili ndi gawo loyenda ngati loyenda lokhala ndi ma cores angapo ndi chingwe cha waya chomwe chili mu rabara.Nyimbo za Diggeringagwiritsidwe ntchito kwambiri pamakina oyendera monga ulimi, makina omanga ndi omanga, monga: makina okumba zinthu zokwawa, makina onyamulira katundu, magalimoto otayira zinyalala, magalimoto oyendera, ndi zina zotero.
