1. A compaction roller comprising first and second support discs mounted on a main shaft between which is mounted a inner drum flanked by first and second outer drums, each of said first and second outer drums mounted on a drum support ring which rotates with the main shaft, said main shaft capped at first and second ends with a disc wheel which rotates with the main shaft and which spaces the drums above a surface over which the roller is rolled, said inner drum mounted on an over shaft concentric with the main shaft and rotatable thereon, each of said inner and outer drums having a plurality of spaced apart cutters projecting outwardly from a circumferential surface of the drums, a reversible first drive attached to the main shaft and a reversible second drive attached to the over shaft, said first and second drives independently operable such that the outer drums and the inner drum are rotated in the same or opposite directions.

6. A trash compactor and pulverizer with a compaction roller attached to a plate with first and second arms, said plate adapted to be mounted on a boom of a self-propelled vehicle capable of exerting a downward force on the roller and propelling the roller across trash to be compacted and pulverized, said roller comprising first and second support discs mounted on a main shaft between which is mounted a inner drum flanked by first and second outer drums, each of said first and second outer drums mounted on a drum support ring which rotates with the main shaft, said main shaft capped at first and second ends with a disc wheel which rotates with the main shaft and which spaces the drums above a surface over which the roller is rolled, said inner drum mounted on an over shaft concentric with the main shaft and rotatable thereon, each of said inner and outer drums having a plurality of spaced apart cutters projecting outwardly from a circumferential surface of the drums, a reversible first hydraulic motor attached to the main shaft with a sprocket drive and a reversible second hydraulic motor attached to the over shaft with a sprocket drive, said first and second hydraulic motors independently operable such that the outer drums and the inner drum are rotated in the same or opposite directions.

10. A trash compactor and pulverizer with a compaction roller attached to a plate with first and second arms, said plate adapted to be mounted on a boom of a self-propelled vehicle capable of exerting a downward force on the roller and propelling the roller across trash to be compacted and pulverized, a breaker plate mounted on the arms above the roller, said roller comprising first and second support discs mounted on a main shaft between which is mounted a inner drum flanked by first and second outer drums, each of said first and second outer drums mounted on a drum support ring which rotates with the main shaft, said main shaft capped at first and second ends with a disc wheel which rotates with the main shaft and which spaces the drums above a surface over which the roller is rolled, said inner drum mounted on an over shaft concentric with the main shaft and rotatable thereon, each of said inner and outer drums having a plurality of spaced apart cutters projecting outwardly from a circumferential surface of the drums, a reversible first hydraulic motor attached to the main shaft with a sprocket drive and a reversible second hydraulic motor attached to the over shaft with a sprocket drive, said first and second hydraulic motors independently operable such that the outer drums and the inner drum are rotated in the same or opposite directions.
