Abstract: An improved positioning device (“the DEVICE”) comprises a new and unique concave angulated device for at least one of, but not limited to, stretching, supporting, bracing, rehabilitating, positioning, massaging, kneading, scratching, or exercising a body of a user. The DEVICE's new concave angulated and more user friendly surface addresses the need for a more anatomically responsive body positioning DEVICE for achieving improved results relative to, among other things, the above uses. This DEVICE includes multiple embodiments, which also may comprise various possible configurations, that enable the DEVICE to also function as a fulcrum or lever and/or be capable of uniquely dispersing a load during the interaction between the user and the DEVICE.

Abstract: A conservation no till apparatus for placing seed and fertilizer into the ground in one operation as pulled through the field includes a main implement frame having ground engaging support wheels. Hoppers for supplying the seed and fertilizer are supported on the ground separately from the main implement frame. A plurality of ground working units are mounted to the main implement frame in separate laterally spaced relation by four-bar linkage assemblies. Each ground working unit is thus movable by its linkage assembly between a raised transport position and a lowered ground engaging position, with the linkage assembly for each unit permitting that unit to move vertically independently of the other units when the units are in the ground engaging position. Each ground working unit includes a unit frame and a plurality of ground working tools staggered laterally and longitudinally for engaging the ground and creating separate furrows when the unit is in its ground engaging position.
