1. An apparatus for collecting yard debris disposed on a surface comprising:
- a. a chassis frame;
b. a blower unit mounted on said chassis frame and adapted to induce an entraining air flow;
c. a collector rotor rotatably mounted on said chassis frame adapted to;
i. engage said surface and said yard debris thereupon, andii. impel said yard debris toward said blower unit;
d. a conduit adapted to conduct said yard debris in said entraining air flow from said collector-rotor to said blower unit;
e. an upwardly opening accumulatori. detachably attached to said chassis frame,ii. operatively connected to said blower unit,iii. having a rigid perimetral frame, andiv. being adapted to receive said yard debris from said blower unit; and
f. said upwardly opening detachable accumulator having at least one attached roller adapted to support said upwardly opening detachable accumulator upon detachment of said accumulator from said chassis frame.

Abstract
An apparatus for collection of yard debris combines a vacuum pick up with a blower unit, a separator, and a detachable accumulator with an attached roller to support the accumulator upon detachment from the separator. The apparatus collects and entrains debris in an airflow induced at the vacuum pickup, impels the debris to the separator which removes the debris from the airflow, and deposits it in the accumulator which is supported by a roller to aid subsequent dumping when the accumulator is detached.
