A yard waste collection device having an integral body, handle, and clamping means. The integral body has a planar surface and a continuous side. The continuous side has a large opening. Leaves and grass clippings can be raked or swept into the integral body and through the opening. A lawn or leaf bag, held in place by the clamping means, collects the leaves.

A land vehicle comprises first and second wheel motors that control respective rates of rotation of left and right rear wheels. An accelerator adjustment assembly controls the first and second wheel motors and comprises first and second linkage assemblies that cause the rate of rotation of an inside rear wheel to slow during a turn exceeding a predetermined turning radius. In preferred embodiments, the land vehicle is a sweeper machine comprising a debris collection assembly, a hopper, and a hydraulic cylinder adapted to lift and lower the debris collection assembly. The debris collection assembly comprises a collection body, a brush adjustment assembly, and a rotary brush assembly. The brush adjustment assembly comprises a height adjustment lever and an actuator comprising a piston rod. The piston rod is adapted to raise and lower a first end of the height adjustment lever such that the rotary brush assembly is raised and lowered.

A debris collection device for collecting and transporting debris includes a shell, which defines an interior space. The shell is flexible and thus collapsible. The shell has a top, which is open for insertion of articles, such as debris, into the interior space. A pair of sleeves is engaged singly to and extends along opposed sides of the shell proximate to the top. Each of a pair of poles is selectively insertable into a respective sleeve so that opposed terminal sections of the pole protrude from the sleeve. The opposed terminal sections can be grasped in hands of user, positioning the user to lift the shell and the articles.
