Abstract
A self-propelled vehicle includes a waste processing attachment. The vehicle is adapted for being moved over a supporting surface, and has a moveable working arm for reaching outwardly from the vehicle and downwardly beneath an adjacent surface of a waste lagoon. The waste processing attachment injects and mixes a waste processing material into the lagoon. The attachment includes a bucket mounted on a free end of the moveable working arm, and having a plurality of spaced-apart waste sifting openings. A material delivery line extends along the working arm of the vehicle, and has a connecting end connected to a material supply source and a discharge end residing proximate the bucket. Waste processing material flowing through and exiting the delivery line beneath the surface of the waste lagoon is discharged into a target area directly adjacent the bucket and mixed with the waste as the bucket is carried by the working arm through the lagoon.
