41	Method and equipment for interseeding an area of ground to convert the existing vegetation or to improve the quality of the existing vegetation	US11189992	2005-07-26	US07409916B2	2008-08-12	Jack Fry; Randy Taylor; Bob Wolf; Dick Stuntz
Methods and apparatus for interseeding an area of ground having existing vegetation growing thereon are provided. The interseeder apparatus tills a plurality of spaced-apart rows in the ground, deposits seed in the exposed soil of the rows, compacts the seed into the rows, and optionally, sprays at least a portion of the exiting vegetation adjacent the rows with a herbicide so as to reduce competition for the new seedling.
42	Method and system for high pressure liquid injection of turf seed	US10217133	2002-08-12	US20030051650A1	2003-03-20	Milton C. Engelke; Kevin E. Kenworthy; Laurence B. Jones
A turf care system and method uses simultaneously fired pulses of high-pressure liquid jets of the mixture shot toward the ground. The liquid is mixed with dry grass seed shortly before being delivered to a high-pressure liquid/seed pumping system, which uses an accumulator and sequencing valve to produce at regular repetitive intervals pulses of the liquid/seed mixture under high pressure. The pulses are delivered to an elongated hydraulic manifold having multiple nozzles pointed downwardly, which are spaced from one another and the ground by predetermined distances. The momentum of the high-pressure jet of liquid/seed mixture issuing from each nozzle cuts through overlying vegetation to deposit the seeds into the crown of the soil at predetermined desired depth. Spray patterns are determined by nozzle orifice shape, and are preferably selected to provide a shallow knife slit-like opening or trench in the crown of the turf.

A turf care system and method for injecting a liquid/seed mixture into soil, such as the crown of an established turf stand, using simultaneously fired pulses of high-pressure liquid jets of the mixture shot toward the ground. The liquid, typically water, is mixed with dry grass seed shortly before being delivered to a high-pressure liquid/seed pumping system, which uses an accumulator and sequencing valve to produce at regular repetitive intervals pulses of the liquid/seed mixture under high pressure. These pulses are delivered to an elongated hydraulic manifold having multiple nozzles pointed downwardly, which are spaced from one another and the ground by predetermined distances. The momentum of the high-pressure jet of liquid/seed mixture issuing from each nozzle cuts through overlying vegetation to deposit the seeds into the crown of the soil at predetermined desired depth. Spray patterns are determined by nozzle orifice shape, and are preferably selected to provide a shallow knife slit-like opening or trench in the crown of the turf. The seeds come to rest near the trench bottom, thus providing good soil-to-seed contact and good light. The trench also collects water and nutrients. The adjacent and underlying turf stand provides excellent physical protection for the soon-to-germinate seeds and resulting seedlings. This liquid/seed injection system and method for planting turf grass seeds has several beneficial results, including ease-of-use, reduced time and effort to plant seeds, reduced energy requirements, and reduced disruption to the surface of the turf or soil in comparison to other methods of interseeding turf.
44	Modular dethatcher and seeder	US09432437	1999-11-02	US06347593B1	2002-02-19	Richard Tadashi Moran; Edward T. Biegel
A modular dethatcher and seeder includes a housing having a rear opening, a removable rear cover substantially closing the rear opening, and a plurality of tines driven by a motor to rotate about a shaft within the housing. When the device is to be used as a seeder, a seeder attachment is inserted into the rear opening of the housing in place of the rear cover. The seeder attachment can be driven by the rear wheels of the device. Alternatively, when the device is to be used as a dethatcher, a chute can be removably attached to the rear opening and a collection bag is then attached to the chute to hold debris thrown by the tines.
45	Seeder apparatus for dispensing seed with or without top dressing	US675653	1996-07-03	US5802994A	1998-09-08	George B. Kinkead; Vernon J. Worrel; Scott Bjorge; Matthew A. Donner
The seeder apparatus includes a first hopper for dispensing seeds onto a conveyor mechanism to be moved thereby to an entry nip between a rotary brush and the conveyor mechanism for propelling the seed downwardly at the discharge end of the frame on which the hopper is mounted. A shield assembly is mounted to the frame discharge end portion to minimize the effects of wind on the trajectory of seed or other material being propelled to the ground by a brush and conveyor mechanism. In one embodiment, a metering gate extends vertically in its closed position relative to the conveyor mechanism, the metering gate controlling the rate of dispensation of seed being moved to the entry nip. In a second embodiment, the seed hopper is mounted to a top dresser hopper whereby either seed from the seed hopper and/or dressing material from the top dresser hopper may be moved by the conveyor mechanism to the entry nip, with a top dressing metering gate being provided for controlling the rate of dispersion of material from the top dresser hopper to the entry nip.

A machine for slicing and seeding a lawn includes a number of seed distributing discs which are arranged as a bank that is freely pivotable on a vertical axis, to automatically follow in grooves made by slicing blades mounted forwardly in the machine. Weight distribution, and the relationship between the axis of the bank of blades and the front wheels, contribute to the maneuverability and efficiency of operation of the machine.
47	Grass seed planter having fluid injection soil opener	US117454	1980-02-01	US4300461A	1981-11-17	Ronald F. Hodge; George D. Fears
A mobile grass seed planter having mounted thereon a frontal line of spaced water nozzles, and behind each nozzle, in a second or back row, is a row of outlets through which seed is directed under air pressure. In operation, as the planter is moved over the earth, a plurality of parallel narrow grooves are cut into the earth by the pressurized water, and the seed is then blown into the grooves. The liquid and airblown seeds are supplied to the planter via hoses from pressurized sources, typically mounted on a truck, tractor, or trailer.
