Abstract
A device for mowing, cutting, and mulching of vegetation in a single pass over the terrain. A movable folding shroud is provided that is pivoted upward to expose a cutter for severing larger trees. The device may be configured so that mowing, cutting, and mulching operations are all performed while traveling in the same direction. Alternatively, the device may be configured so that mowing and mulching operations are performed while traveling in one direction, with cutting operations performed while traveling in the opposite direction. The device may also be configured with a dispensing assembly for applying chemicals onto the cut vegetation to obtain a more effective kill and minimize re-growth.

- a frame;
- cutting means for mowing, cutting, and mulching coupled to said frame, wherein a portion of said cutting means extends beyond one end of said frame;
- a deck coupled to said frame, said deck lying in a first plane substantially parallel to a path of said cutting means;
- a first lateral shroud coupled to said deck and disposed below said first plane along:
- a first lateral side of the device;
- a second lateral shroud coupled to said deck and disposed below said first plane along a second lateral side of the device;
- a folding shroud movably coupled to said one end of said frame, said folding shroud comprising a top portion and a cutter enclosing portion, said folding shroud movable in a second plane substantially perpendicular to said first plane between a downward enclosing position and an upward exposing position;
- wherein in said downward enclosing position, said top portion of said folding shroud covers said portion of said cutting means, and said cutter enclosing portion encloses below said first plane said one end of said frame from said first lateral side to said second lateral side, thereby enclosing said cutting means for mowing and mulching;
