Abstract: A unique coulter has a flat band adjacent the peripheral cutting edge to form a slot. Inwardly of this flat band, and on one side of the coulter blade is an inclined compacting surface. The outer, cutting edge of the coulter enters the soil first and as the machine moves forward the compacting surface of the coulter is brought into engagement with one wall of the partially formed slot to firm the soil adjacent the top of the wall. At the rear of the coulter, behind the compacting surface, there is a delivery chute or tube for depositing the fertilizer into the slot formed by the coulter.

Abstract: A finger wheel adapted to follow behind and/or beside a furrow opener at varying angles to the vertical and to the direction of travel. The finger wheel is useful for covering a furrow with loose soil to retain gaseous material such as anhydrous ammonia in the soil. The finger wheel is also useful for removing dry soil from the top of a seed furrow to reduce the effective depth of seeding and improve emergence. Also provided are a gaseous material injector and seeding apparatus using a known double inclined disc in combination with the finger wheel.

Abstract: A coulter disc assembly is pulled by a tractor or other motorized vehicle to create a trench in the ground into which seeds are dispensed. This mounting arrangement of the present invention allows a farmer to inject agricultural additives, such as either liquid or dry fertilizer, into the ground so as to come into contact with the seed immediately after the trench is created and before it is covered over. The mounting arrangement consists of an elastomeric mounting block adapted to connect to a coulter disc frame. A rigid guide rod extends from the mounting block downwardly toward the ground. One end of a tube is connected to a supply of agricultural additives and the other end to the lower end of the guide rod. As the coulter disc passes through the ground to create a trench, the lower end of the guide rod is carried in the trench. As the guide rod engages the side walls of the trench, the rubber mounting block allows the guide rod to pivot rearwardly in the direction opposite the travel of the disc.

Abstract: A spring-cushioned coulter running ahead of the applicator for cutting an initial slot in any residue and for providing a break line for the soil to be parted by the trailing shank. The trailing shank, in turn, spreads the initial slot, and deepens it, for the entry of a slurry delivery tube welded behind the shank. At the bottom of the shank is a shoe having a pair of side wings. A downward and outward slope of the wings creates a flat, peaked soil profile ("sole") beneath the wings having sides which slope downwardly and outwardly, conforming to the shape of the wings. The lift surfaces of the wings slightly raise the soil laterally of the shank from the center toward the ends of the wings to provide slots or fissures above the sloped edges of the sole, permitting, and promoting the lateral distribution of the slurry.

Abstract: A process for treatment of turf by applying a turf treating material in a stream within a narrow slit formed in the turf below the turf growth zone. The slit is made to extend downwardly through the exposed leafy mat in a growth zone and at least part way through the thatch zone situated between the growth zone and a root/soil zone. The slit is formed by a coulter disk rolled in a forward direction of travel with a cutting edge aligned in relation to the forward path to minimize slit. A knife follows the disk to hold the slit open. Turf treating material is placed into the slit directly behind the knife. A skid is used, with the disk extending through slots formed therein to ride over the turf and prevent disruption of the leafy growth, thatch, roots and soil as the slit is being formed. The turf is allowed to close over the placed material thereby capturing the material at a selected depth for maximum effectiveness and to prevent runoff or evaporation of the material.
