An aquatic sporting device, designed for use with one arm, is formed of three removably attached sections including a paddle blade, a forearm brace, and an elongate longitudinal shaft between the blade and brace. The brace is offset both longitudinally and transversely from a proximal end of the shaft, to permit placement of the brace against the forearm at the elbow, yet permit full bending of the arm at the elbow. A hand gripping area is provided along the shaft, and enables selective gripping along the shaft length to facilitate positioning of the elbow with respect to the brace for maximum paddling leverage, regardless of the size of the forearm. When removed from one another, the sections can be conveniently stored or transported. The removable mounting further permits substitution of other working implements, such as a fish net or gaff hook, in lieu of the paddle blade.

A grass catching attachment for use on a rear bagger mower has a rearwardly facing grass discharge chute and a bag support for holding disposable plastic garbage bag in position to receive air and grass clippings from the discharge chute. The bag is mounted adjacent a base housing that includes a discharge opening for the grass at its lower portions, and an air outlet at the upper portions which joins to a conduit that directs the return air forwardly of the mower. Thus, any debris, short grass clippings, pollen, dust or the like that might be carried with the air discharging from the bag is firm from the user in front of the mower and recycled through the grass catcher. The bag is held in a basket that permits easy installation and removal, and substantially increases the amount of grass which can be packed into the bag.

In a pre-weaned piglet protector, sharp bursts of compressed air from dome shaped nylon air nozzles located one foot away from each other longitudinally in a farrowing area are used to irritate baby piglets. The farrowing area has a safety zone where the sow cannot sit. The area beneath the sow is covered by these sharp bursts of air. The nozzles keep bursts of air away from the baby pigs in the safety zone so they have a tendency to move to the safety zone to avoid the irritation of the air bursts. The air bursts are of a pressure and duration which is uncomfortable for the baby piglets but not sharp enough to cause any harm. The bursts of air are under the control of a controller which opens and closes the air solenoid with precisely metered intervals. The controller is activated by a diffuse reflection photoelectric sensor switch that hangs directly above the sow and detects her inclinations. When the sow gets up the sensor switch activates the controller which sends a pulsing signal to the air solenoid valve.
