ABSTRACT:
A vacuum grass collecting apparatus for a tractor-type lawnmower having a rear discharge opening in its cutting deck and a rear power-take-off. A refuse container and a blower are independently mounted on the rear of a tractor-type lawnmower. The blower consists essentially of a housing having an intake opening and a discharge opening, a rotatable drive shaft having a plurality of impeller blades mounted thereon and a support bearing for the rotatable drive shaft. An articulated duct is positioned under the rear axle of the tractor-type lawnmower and interconnects the rear discharge opening in the cutting deck and the intake opening in the housing of the blower. Another duct interconnects the discharge opening in the housing of the blower and an intake opening in the refuse container. The entire apparatus is positioned between the two imaginary parallel vertical planes which contain the outer extremities of the tractor-type lawnmower. With this apparatus, it is possible to mow close to buildings, flower beds, trees and similar obstacles with either side of the cutting deck of the lawnmower while continuously removing cut grass from the lawn.
