A hand-held tilling device for powered hand-held tilling of substrate includes a support that is hollow. A drive assembly is coupled to a top end of the support. The drive assembly is configured for grasping in a hand of a user. A tillage assembly is coupled to a bottom end of the support. The tillage assembly is drivingly coupled to the drive assembly. The drive assembly is positioned on the support for grasping in the hand of the user. The drive assembly is positioned to motivate the tillage assembly to till a substrate selected by the user.

A land clearing attachment for a tractor device includes semi-helically oriented teeth, knives, or blades radially outward from an outer surface of a rotor. Each tooth, knife, or blade is part of a row of independent teeth, knives, or blades. Each row is oriented with an offset angle such that the spirally orientation completes angular offset of about 90? or less. The spiral or helical orientation of the cutting teeth, knives, or blades enables the power to be reduced typically required to effectively rotate a similarly sized rotor.

An agricultural row unit for use with a towing frame hitched to a tractor includes an attachment frame adapted to be rigidly connected to the towing frame, a linkage pivotably coupled to the attachment frame, and a row unit frame having a leading end pivotably coupled to the linkage to permit vertical pivoting movement of the row unit frame relative to the attachment frame. A hydraulic cylinder coupled to the attachment frame and the linkage, for urging the row unit frame downwardly toward the soil, includes a movable ram extending into the cylinder, and a hydraulic-fluid cavity within the cylinder for receiving pressurized hydraulic fluid for advancing the ram in a direction that pivots the linkage and the row unit frame downwardly toward the soil. An accumulator positioned adjacent to the hydraulic cylinder has a fluid chamber containing a diaphragm, with the portion of the chamber on one side of the diaphragm being connected to the hydraulic-fluid cavity in the hydraulic cylinder, and the portion of the chamber on the other side of the diaphragm containing a pressurized gas.

A knife for a cylindrical rotor includes at least two sharpened edges adapted to cut materials during land clearing or mulching. The knife further includes a top surface and a bottom surface wherein the knife is shaped as an inverted frusto-square pyramid. The knife may further include a tapered sidewall defining one sharpened edge. The angle may be about 30? to about 60?. The knife may have four sharpened edges. The knife further may include an aperture that may be equidistant from the four sharpened edges. The knife is adapted to be moved when one sharpened edge becomes dull. The knife may further include a conical countersunk aperture. The knife may have a thickness of about ? to about ?.

A tilling implement includes a frame, a row of disc blades coupled to the frame, and a soil finisher coupled to the frame. The soil finisher includes multiple chopper blades, each chopper blade of the multiple chopper blades includes multiple fins that extend radially from a hub, a first set of the multiple fins bend in a first direction relative to the hub, and a second set of the multiple fins bend in a second direction relative to the hub to facilitate tossing soil as the tilling implement travels through a field.

An attachable tilling device for a vehicle is provided. The device includes a housing having a base member, wherein a pair of opposing side members extend downwardly from a first end and a second end thereof. A bar member is rotatably affixed between the pair of opposing side members, wherein the bar member rotates about a longitudinal axis. The bar member includes a plurality of tilling blades affixed thereto. A gear system is operably connected to the bar member, wherein the gear system rotates the bar member. A gearbox is disposed on an upper side of the housing, wherein a pair of shaft members are operably connected to the gearbox, wherein a first shaft member connects to the gear system and a second shaft member connects to a motor, such that when the motor is actuated, power is transferred to the gearbox, thereby rotating the plurality of tilling blades.

A drawbar for finishing attachments is arranged to attach to a fore-aft frame member of a tillage implement. The drawbar has a saddle with spaced apart side walls defining a channel configured to receive the frame member. When the frame member is received in the channel, the side walls of the saddle overlap side walls of the frame member and extend in the fore-aft direction rearward of an end of the frame member. The side walls of the saddle and the frame member have mounting openings that align along a lateral direction transverse to the fore-aft direction.

A gardening system includes a drive shaft operably coupled to first and second shafts for driving the first shaft in a first direction and the second shaft in a second direction. A first ground manipulation device is attached to the first shaft. A second ground manipulation device is attached to the second shaft.

A carrier adjustment assembly for coupling to a frame member of an implement includes a laterally adjustable carrier configured to be coupled to an opener and a first outlet providing at least one nutrient. The assembly further includes a plurality of lateral spacers positioned adjacent to the carrier to laterally adjust the carrier and provide a plurality of adjustment positions. The carrier adjustment assembly facilitates lateral adjustment of the carrier by removal of at least one captively held lateral spacer that sets the lateral adjustment of the carrier, a lateral adjustment of the first outlet, and an adjustment of a lateral separation between a seed row provided by a second outlet and a nutrient row provided by the first outlet.
