Rotary cutting deck with asymmetric rear discharge opening

A rotary cutting deck, comprising:

• a circular inverted dish-shaped cutting chamber;
• a hydrostatic motor mounted to a recess in a top surface of the deck;
• the motor turning a rotary cutting blade attached to a generally vertically aligned spindle extending from the motor under the deck;
• a framework supporting the cutting chamber and carrying a front pair of rollers and a rear roller;
• and
• an asymmetric rear discharge opening extending partially around the perimeter wall of the cutting chamber;
• the opening having an upper edge that slopes upwardly and radially inwardly between a first end and a second end of the opening, whereby the upper edge adjacent the first end of the opening is outside a radius of the rotary cutting blade and the upper edge adjacent the second end of the opening is within the radius of the rotary cutting blade;
• and a portion of the rear wall of the cutting chamber forming a band below the opening.

A rotary cutting deck, comprising:

• an inverted dish-shaped cutting chamber covering a rotary cutting blade rotating in a generally horizontal plane and powered by a hydrostatic motor;
• the cutting chamber having a rear wall with an asymmetric rear discharge opening having an upper edge that inclines upwardly and radially inwardly in the direction of rotation of the rotary cutting blade, whereby only a part of the upper edge is within a radius of the rotary cutting blade;
• and
• a band integral with and extending around the rear wall of the cutting chamber in the generally horizontal plane of the rotary cutting blade.
