Abstract
A powered vacuum is mounted between a tractor carrying a rotary mower and a trailer carrying a receptacle for moving material from the mower discharge to the receptacle. A mounting frame carries a blower which may include either an internal combustion engine or gearbox and a fan coupled directly to the engine or gearbox. The mounting frame is mounted to the tractor by connections defining three coplanar ball joints located to permit relative pitch and roll between the tractor and trailer. The mounting frame is easily releasably secured to the tongue of the trailer. The mounting frame is articulated between its opposite ends for movement about a tight vertical axis. The mounting frame, in one form, defines a receptacle for receiving a support member of a wheeled dolly for supporting the powered vacuum when the mounting frame is disconnected from the tractor and trailer, and in another form includes retractable wheels which may be selectively placed in an operative condition for supporting the vacuum.
