Abstract: A two-wheeled riding sulky for powered ground-maintenance machines includes, in addition to a primary hitch connection which operates in tension between the powered ground-maintenance machine and the sulky, a buck-bar which operates in compression between these two devices. The buck-bar is used to prevent the powered ground-maintenance machine from bucking. In a preferred embodiment, the powered ground-maintenance machine is a snow blower having only two ground-engaging, load-bearing traction wheels.

Abstract: A composite insulated building structure which can be fabricated on site. Structural members are lined with secondary framing strips to minimize thermal conduction therethrough from interior to exterior walls. The structural members are applied in a staggered fashion to increase the effectiveness of the insulation. Interior and exterior walls of the structure are formed and then filled with insulation by pouring, thereby causing bonding of the insulation to the walls. Excess insulation material flows out into the unfilled structural void or over the top of the section to avoid undue stress on the shell.
