In some embodiments, the seeder may further include a handle for adjusting the height of the one or more blades, a plurality of interlocking teeth, and a spring. The spring may provide a load to counteract the force of gravity on the one or more blades. The aerator may also include a flap located between the opening and the one or more blades.

A reseeding device (1) is 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. This reseeding device (1) prevents loosend material from forming an ipediment during reseeding.

Coir plugs have spherical plugs of coir pith having a diameter in the range of 1 to 3 inches having a seam between two halves of the plug, and indentations in a surface of the plugs, configured to receive a seed. A method of producing coir plugs includes at least one compressing of coir material using opposed half ball cup cylinders to produce spherical plugs having a diameter in the range of 1 to 3 inches and a seam between the two halves, and forming an indentation in a surface of the spherical plugs.

An electric-powered bulk material dispersing system and method of use. The electric power is provided by a battery system with one or more electric motors to replace traditional internal combustion engines. The electric motor or motors are used to provide pressure to one or more pumps that may be used in conjunction with various tubes, hoses or related conduit and spray nozzles in order to disperse a bulk material such as seed, mulch, compost, chipped wood, grain, hay, fertilizer, herbicide, pesticide, plastic pellets, salt, sand or the like that has been combined or suspended within a fluent material. In one form, the bulk material dispersing system may be used as a bulk hydroseeder.

An aerial seeding bioremediation method for a coal mining subsidence area. The method includes obtaining a topographic map of the coal mining subsidence area; grading the topographic map in terms of ground slopes; determining seeding coefficients of aerial seeding operation according to a grading result of the ground slopes and ground coverage rates of the coal mining subsidence area; determining height adjustment parameters during unmanned aerial vehicle, UAV, aerial seeding; and performing, by a UVA, the aerial seeding operation according the grading result of the ground slopes, the seeding coefficients of the aerial seeding operation, and the height adjustment parameters. A slop grading technical standard of aerial seeding determined by the method of the present disclosure is applicable to complex topography of the coal mining subsidence area and helps with safety of the UVA.

An automated leveling system for maintaining a level of a surface, comprising a surface traveling device and a leveling module attached to the surface traveling device. The leveling module comprises a depression detector arm assembly, at least one computing device, and a level-sensing detector. The level-sensing detector senses a level of a surface as the surface traveling device operates across the surface. The level-sensing detector moves across the surface according to the operation of the surface traveling device, and transmits a depression reporting signal to the computing device. The depression reporting signal indicates the presence of a depression in the surface if the level-sensing detector contacts a depression in the surface over a depression threshold.

Coir plugs have spherical plugs of coir pith having a diameter in the range of 1 to 3 inches having a seam between two halves of the plug, and indentations in a surface of the plugs, configured to receive a seed. A method of producing coir plugs includes at least one compressing of coir material using opposed half ball cup cylinders to produce spherical plugs having a diameter in the range of 1 to 3 inches and a seam between the two halves, and forming an indentation in a surface of the spherical plugs.

An agitator, a planting system including the agitator, and methods of using the agitator to agitate seeds in a hopper, are described. The agitator can be mounted within the hopper of the planting system. The hopper can be transported by an unmanned aerial vehicle to spread the seeds over a geography. The agitator can include one or more arms that oscillate through a sweep angle to move one or more paddles through the seeds. An outlet of the hopper can be within the sweep angle such that the arms and paddles sweep seeds into the outlet as the arms oscillate within the hopper. The sweep angle can vary over time by incrementally increasing the sweep angle during several stages. The varying sweep angle maintains consistent seed mixing and spreading over time. Other embodiments are also described and claimed.

A seed delivery system for use in a seeding or planting machine that removes the seed from a seed meter by capturing the seed therefrom. The delivery system then moves the seed down to a lower discharge point and accelerates the seed horizontally rearward to a speed approximately equal to the forward travel speed of the seeding machine such that the seed, when discharged has a low or zero horizontal velocity relative to the ground. Rolling of the seed in the trench is thus reduced. Furthermore, as the seed only has a short drop from the outlet to the bottom of the seed trench, the seed has little vertical speed to induce bounce. The delivery system uses a brush belt to capture, move and accelerate the seed. By capturing the seed and moving it from the meter to the discharge, the seed is held in place relative to other seeds and the planter row unit. As a result, the seeds are isolated from row unit dynamics thereby maintaining seed spacing.
