Riding apparatus for mowing and pressure surface cleaning

A riding apparatus for mowing and pressure surface cleaning with recovery of dirty water, the riding apparatus comprising:

• a chassis;
• a mower deck mounted to the chassis;
• a spindle mounted to the mower deck, the spindle comprising an elongated shaft having a top end and a bottom end;
• a mower blade mounted to the bottom end of the elongated shaft and rotatable about a vertical axis;
• wherein the mower blade includes at least one blade-formed aperture extending through a thickness of the mower blade at a location radially offset from the vertical axis;
• a rigid fluid conduit extending through the elongated shaft and terminating at a distal end that passes through the blade-formed aperture such that the distal end rotates together with the mower blade;
• a nozzle fixedly coupled to the distal end of the rigid fluid conduit and positioned below the mower blade, the nozzle being oriented to eject pressurized water downwardly toward a surface beneath the mower deck while rotating with the mower blade;
• a high-pressure pump in fluid communication with the rigid fluid conduit, wherein the high-pressure pump is configured to pressurize water for pressure surface cleaning;
• and
• wherein the nozzle is removable from the blade-formed aperture to permit operation of the riding apparatus in a mowing-only mode.
