The invention relates to a loader-mounted rock extractor usable in fields. It is composed of the bucket 1 provided with in-series arranged tubular housings 2, tubular tines 4 fixed on tubular bases 6 whereto two-leg spear-like portions 7 are permanently adfixed. To each tubular housing 2 corresponds a tubular tine 4 adaptable to the tubular base 6 bearing a two-leg spear-like portion 7. The size of the free end 9 of the two-leg spear-like portions 7 is gradually reduced to simultaneously engagethe soil, extract the stones therefrom, load up the stones into the bucket 1 and plough the field. |
