Abstract
A combination self-propelled lawn mower and wheeled cart for receiving and storing mower clippings. The mower is connected to the cart by an arm which turns a vertical drive shaft centrally located within the cart. This drive shaft is, in turn, geared to an axle attached to two wheels. As the mower moves, it circles the cart, and simultaneously rotates the drive shaft, and hence the axle. The cart is thus propelled forwardly, the mower simultaneously circling or orbiting about the cart. A chute attached to the mower receives clippings, and discharges the same into a receptacle located on the cart. One manual control located on the cart disengages the motive power to the cart wheels. A second manual control disengages motive power to the mower wheels. The mower and cart each have a combination of fixed and caster wheels, to stably and smoothly negotiate terrain. The arm connecting the mower to the cart is adjustable as to its position on the cart, so that the chute and an opening formed in the top of the clippings receptacle align appropriately.

20. A grass cutting device comprising:
-
a powered, self-propelled mower having a motor, a cutter operably connected to said motor, wheels supporting said mower, one said wheel being a driven wheel drivingly connected to said motor, and a mower wheel engagement mechanism attached to said mower, operating selectively to engage and disengage said driven wheel from said motor, said mower wheel engagement mechanism comprising; a drive cog rotatingly driven by said mower and pivotally mounted on said mower to travel in an arc intersecting said driven wheel; and an engagement arm movably attached to said mower and connected to said drive cog, said engagement arm selectively movable to move said drive cog into and out of engagement with said driven wheel; a cart having wheels including driven wheels, an axle drivingly connected to said wheels of said cart, a drive shaft rotated by said mower and connected to said axle of said cart by gears, said drive shaft being vertically supported within said cart, said cart also having a receptacle for receiving clippings cut by said cutter and transported by said cutter to said receptacle, said cart further comprising a handle attached thereto for maneuvering; a cart drive detent for controlling driven connection of said wheels of said cart to rotary power provided by said mower, wherein said axle of said cart has a central section, and two wheel sections each connected to one said wheel of said cart, said cart drive detent comprising two collars each having means defining a pair of diametrically opposed slots therein and a central radially oriented external flange, each said collar aligned with and telescopically engageable with one of said two wheel sections of said axle, each said wheel section of said axle having a pin projecting radially therefrom, each said pin engageable with an associated said collar by penetrating said groove of said associated collar, said cart drive detent further comprising a collar positioning yoke engaging said two collars and selectively sliding said two collars into and out of engagement with said two wheel sections of said axle, said cart drive detent further comprising a lever mounted to said cart for actuating said yoke, said lever contacting and engaging said yoke, said lever having an end accessible to a human operator on the exterior of said cart, whereby driving contact of said connecting arm is interrupted by moving said lever, said cart drive detent further comprising a spring mounted to said cart and to said yoke, urging said yoke into the engaged position; a chute for conducting clippings cut by said cutter to said receptacle; and a connecting arm connecting said mower to said cart and engaging and rotating said vertically supported drive shaft, whereby operation of said mower drives said cutter and propels both said mower and said cart, said drive shaft being centrally located within said cart, whereby said mower orbits concentrically around said cart, said connecting arm having means for adjusting angularity of said connecting arm with respect to said cart, said mower having two fixed wheels and a caster wheel, for stably supporting said mower on the ground and to enable smooth tracking as said mower moves along the ground, and said drive wheels of said cart being fixed to said cart, and said cart further having at least one caster wheel attached thereto, said drive wheels of said cart and said caster wheel of said cart stably supporting said cart on the ground and enabling smooth tracking along the ground.
