Abstract: ABSTRACT OF THE DISCLOSURE    The specification of the present application discloses a geared hub for use in transmitting power to the wheels of a vehicle.  The geared hub is particularly useful for all terrain type vehicles where high strength and reliability are required.  The hub uses a one-piece cast housing having various access means to allow assembly of the unit.  The one-piece housing defines an elongated gear chamber which extends generally perpendicular to the wheel spindle.          Three access ports are provided; one for supporting the wheel spindle, a second port for allowing the insertion of an input pinion and input shaft, and a third port for allowing insertion of the output gear.  The first two ports are located in the end walls of the gear chamber with the third port located in the sidewall of the gear chamber.          The unique design, according to the present invention, results in an inherently strong and durable hub having reduced manufacturing and assembly costs.

Abstract: DIBBLE TUBE SOIL PLUG PLANTER              Abstract of the Disclosure A planter is moved through a field to place two rows of four plants on the top of a planting bed between adjacent irrigation furrows.  Plants ready for transplant are disposed in trays within polymerized cast soil plugs.  Each plug is disposed within the tray in a hole.  Each tray has rows and columns of plant receiving holes extending through each tray.  The planter carrying the plugs moves in increments and sets the planter mechanism in a stationary position over the top of the planting bed prior to plug planting.  The tray carrying the transplants is registered horizontally and vertically to a plug receiving cylinder by respective cams and a supporting chain.  Upon registry, polymer plugs containing sprouted plants therein are ejected, typically eight at a time, by ejecting fingers penetrating the plant receiving holes.  Ejection occurs with the plants horizontally disposed into receiving concavities defined within a rotating cylinder.  Rotation of the cylinder drops the ejected plants into receiving funnels, one for each plant.  Upon return rotation of the cylinder, connection of a wind chest to the receiving funnel occurs with an air blast forcing the plug and carried plant downwardly through a tube.  Plant downward travel halts at a reciprocating plate.  Insertion of the plug into the ground begins with penetration of the ground by a dibble spike followed by circumscribing penetration of a dibble tube around the spike.  When the spike is withdrawn, the plant is reciprocated into registry with the dibble tube and the plant blown under pressure down to the bottom of the dibble tube.  With the air pressure applied, the dibble tube is retracted, leaving the plant in its wake.  Compaction occurs by a soft wheel running over the newly sprouted plant.          After planting eight plants simultaneously, the planter incrementally advances, leaving in its wake groups of plants, typically eight lettuce plants on twelve inch centers staggered in approximate 6 inch spacing one from another.   2.
