Abstract: The present disclosure relates generally to a device for collecting and transporting loose material, and in particular, to a device pulled by a vehicle equipped with a turbine, a conduit, an enclosure, and a foldable accordion-type top. This device is equipped with a top made of a plurality of foldable rectangular ribs over which a flexible sheet and air opaque or mesh-line panels are used to regulate the flow of air through the enclosure. At one end the sheet is secured to the loose material conduit where loose material enters the enclosure and at an opposite end the sheet is secured to the tailgate or to the back section of the enclosure. To open the enclosure with a tailgate equipped with this disclosure, a user unlocks the tailgate of the enclosure, flips the back section of the accordion-type roof up toward the front section, and secures the tailgate to the folded accordion-type roof.

Abstract: An improved ground-driven dethatching apparatus having at least two sets of independently rotating sets of dethatching tines. Each tine set is positioned along an independently rotating tine shaft which is rotated by a separate drive linkage and ground-engaging wheel. This arrangement ensures adequate torque to rotate the shafts and uniform dethatching when changing directions. The dethatcher automatically adjusts tine height, for example, in response to obstructions or variations in ground conditions.
