| 21 | Method and system for high pressure liquid injection of turf seed | US10797696 | 2004-03-09 | US20040187752A1 | 2004-09-30 | 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. | ||||||

| 23 | Apparatus for producing and planting sprigs from bulk sod | US09359983 | 1999-07-23 | US06223662B1 | 2001-05-01 | Anthony W. Lastinger; Jesse B. Grimsley, Jr. |
| An apparatus for producing grass sprigs from bulk sod, evenly distributing the grass sprigs on the ground to be planted, and thereafter planting the grass sprigs. The apparatus comprises a rigid frame member having a driven conveyor assembly, a bulk sod shredding assembly, and a planting assembly. The driven conveyor transports bulk sod to the shredder assembly at a rate proportional to the ground speed of the apparatus, thus providing the proper sprig output rate from the shredder. The shredding assembly utilizes a rotating shaft having a plurality of shredding members extending therefrom for shredding the bulk sod cooperatively with a shredder bar. The planting assembly comprises a sizable chute for guiding the sprigs from the shredder to the ground to be planted without clogging, a plurality of coulters for pressing the sprigs into the ground, and a plurality of press wheels for firming the soil planted subsequent to the coulters. | ||||||
| 24 | Seeder apparatus for dispensing seed with or without top dressing | US148339 | 1998-09-04 | US6058860A | 2000-05-09 | 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. | ||||||
| 25 | Lawn seeding machine | US239589 | 1994-05-09 | US5488917A | 1996-02-06 | Domenico Santoli; George Spector |
| A lawn seeding machine is provided, which consists of a trough for holding grass seeds therein. An inverted U-shaped handle extends upwardly form the trough. A plurality of L-shaped tubular ducts extend in spaced intervals downwardly from the trough. A plurality of spiked seeding wheels are also provided, with each pivotally mounted onto an end of one L-shaped tubular duct. When the spiked seeding wheels are manually pushed along the ground, they will rotate to make holes in the ground and at the same time drop grass seeds directly into the holes received from the trough and one L-shaped tubular duct in a single pass operation. | ||||||
| 26 | Sod planting machine | US663199 | 1991-02-28 | US5083517A | 1992-01-28 | Joel H. Stevens; Arthur W. Ewing |
| A machine for cutting large pieces of sod into smaller, generally square blocks suitable for planting, comprising a cutting mechanism for cutting the large pieces of sod into smaller, generally square pieces of sod which are of generally equivalent size and shape, a discharging means for discharging the smaller pieces of sod onto the ground, and a weighted means to plant the sod into the ground. | ||||||
| 27 | Structural orientation and protective apparatus for tillage assembly | US649278 | 1976-01-15 | US4051792A | 1977-10-04 | Henry William Brandt, Jr.; Donald Thomas Sorlie |
| A structural orientation and protective apparatus is disclosed that is particularly useful in a tillage assembly for sod seeding purposes. The apparatus includes a pair of skids each of which is adjacent to a cutter wheel mounted on the tillage assembly for cutting a furrow in ground to be seeded, each skid including a ground engaging portion to determine the maximum depth of furrow cut by the cutter wheel. Each skid is mounted for pivotal motion about a horizontal axis at the forward end, with the forward end being inclined upwardly from the ground engaging portion. A vertical mounting plate on each skid has a bracket mounted therebetween at the rear portion to receive a vertical adjustment rod, one portion of which is connected to the frame of the apparatus for controlling the selected depth of furrow to be cut. A seed tube boot is fastened to the rear portion of the skid so that regardless of the selected depth of furrow cut, the tube remains in the same position relative to the ground. The particular positioning of the seed boot on the skid, as well as the particular structure of the skid itself, protects the seed boot against foreign objects that could damage or otherwise impair proper functioning of the seed boot. | ||||||

| Methods for growing plants and seeds are described. Methods may include blending a polyacrylamide polymer with the uppermost portion of the soil, usually top 1 inch of the soil at a rate of around 1 pound polyacrylamide per 100 square feet of soil. The polyacrylamide attaches to the roots of the plant and acts as an extension of the root system facilitating the uptake of water by the plant and increasing the soil permeability around the root system. The method also improves germination of the seeds and facilitates the growth of the resulting plants. The method may be utilized with a variety of plants, sod, and trees. | ||||||

| In embodiments, a seeder may include a frame including a seed box and a rear roller. In embodiments, the seeder may be configured to removably couple with either a roller assembly or a disc blade assembly. In some embodiments, the seeder may include a front tray configured to receive two kinds of seed from two different seed boxes and disperse the seed at a position in front of the rear roller so that the seeds are planted at the same depth. In some embodiments, the seeder may further include a calibration tray which may have a width less than a width of the seeder. The calibration tray may be configured to receive seed from the seed box during a calibration procedure. | ||||||

| 38 | Reseeding Device | US15029315 | 2014-10-17 | US20160227702A1 | 2016-08-11 | Frederic Lietaer |
| The present invention relates to a reseeding device (1) configured for introducing grass seeds into an existing turf, comprising a rotatable shaft (2) which is provided with a number of blades (3) along its length which are at right angles to the shaft (2) and which are configured for cutting furrows into the turf and loosening and removing parts of the turf, a seed distributor (4) configured for spreading grass seeds at least in the furrows produced, in which the device (1) is configured, in use, to discharge the material loosened by the blades (3) over the shaft (2) and the seed distributor (4), along a direction (A) opposite to the direction of travel, so that the scattered grass seeds are at least partly covered by the loosened material. A reseeding device (1) of such design has the significant advantage that the loosened material does not form an impediment during reseeding. | ||||||
