ABSTRACT:
An apparatus for the collection of leaves and debris by a vacuuming process is described which features an improved mechanism for supporting and manipulating an intake hose. A stationary support frame is mounted on a leaf collecting apparatus and a swing arm is pivotally attached to the support frame about a vertical axis. An intake hose cradle is fixed to the swing arm and supports the intake hose from underneath. The intake hose may be adjusted vertically by a hydraulic actuator (extensible piston) located on the swing arm which pivots about a horizontal axis in response to movement of the hydraulic actuator. Further, the intake hose may be manipulated from side-to-side by a handle attached to the intake end of the hose, the swing arm allowing lateral movement by utilizing bearings as pivot points along the vertical axis.
