Abstract: A pitching target assembly for training baseball or softball pitchers. A target defines a plurality of zones, each being backed by a pocket or pouch for catching the baseball or softball. The height of the target can be adjusted to match that of a batter. The zones of the target may be adjusted as well, to tailor the targeting within the zone for specific purposes. The target may also be configured at an acute angle relative to a base plane of the pitching target assembly for practicing drop pitches.

Abstract: An apparatus requiring storage of a liquid that needs agitation includes a plastic tank that is rotationally molded around an agitation portion. In a preferred embodiment, an asphalt sealcoat application system has such a plastic rotary molded tank mounted on a powered vehicle or trailer and utilizes a pump connected to a hose and spray wand for application of sealcoat on an asphalt surface. The tank is preferably formed of low density polyethylene resin and the agitation portion includes a plurality of paddles and a shaft extending from the interior of the tank for mixing the sealcoat liquid. The polyethylene tank is rotary molded around the assembled agitation portion. The invention includes the methodology of molding the tank, a tank molded by said methodology, and the apparatus for accomplishing said methodology.
