Abstract
A leaf vacuum and mulching implement for attachment by three-point-hitch to a farm tractor and driven by mechanical connection to the tractor's power tack-off unit (PTO). The implement utilizes a broad vacuum deck having polymeric skirts in near proximity with the ground and a floating three-point-hitch system for lifting the vacuum deck and allowing it to follow the ground contour. High velocity fans blow debris collected by the vacuum deck to a unique, rotating, multifaceted, conical shredding rotor prior to directional dispersion.
