A planting unit includes a seed meter for singulating and dispensing seed. Opening wheels or discs are included to create an opening in the field, such as a furrow. The unit includes one or more continuous tracks for supporting the row unit as it moves through the field. The tracks can be positioned on opposite sides. The tracks reduce compaction around the created furrow and provide better control of seed depth placement. One or more motors are included to operate the tracks to move the planting unit through a field for planting.

A gauge arm (and concomitant method of retrofitting an existing gauge arm) comprising an arm portion, a receptacle portion for receiving two or more sealed bearings, and two or more sealed bearings inserted into the receptacle portion. The receptacle portion is smooth bore, with the sealed bearings being press fit into same. The sealed bearings can be of different dimensions, such as one being a gauge wheel and closing wheel bearing, and one a round bore grain drill bearing. The receptacle portion then comprises a stop within the bore thereof.

A seed tab for a planter has an elongate body configured for attachment to a seed boot of a seed meter. The elongate body has a curved surface defining a first arc having an axis of curvature in a first direction. The curved surface exhibits a concave cross-section defining a second arc having an axis of curvature in a second direction generally perpendicular to the first direction. The elongate body has a first portion having an approximately constant width adjacent the first end. The elongate body has a second portion having a tapered width adjacent the second end. A maximum width of the second portion is greater than the constant width of the first portion. Seeding machines are also disclosed.

A seed meter assembly comprising a main body assembly comprising, a pivot mounting point, a first meter half shell, a seed hopper, and two snap-in attachments. The meter assembly also including a meter cover assembly comprising a second meter half shell and a seed disc, wherein the meter cover assembly and the main body assembly are configured to be fitted together. The meter assembly also including a support structure configured to be attached to the two snap-in attachments to support the weight of the meter assembly and maintaining access to the meter assembly.

A load cell adaptor having a first side for facing a row unit and including at least one contact pad engaged with the row unit, a second side comprising a seat, the seat shaped to be engaged with a load cell, and an opening shaped for engagement with a bolt. the load cell adaptor configured to provide a structure for precise use of a load cell on a traditional row unit.

A particle delivery system of an agricultural row unit includes a first particle disc configured to meter particles and a second particle disc configured to receive the particles from the first particle disc and to transfer the particles toward a trench in soil. The particle delivery system includes a vacuum source configured to reduce air pressure within a first vacuum passage to couple the particles to one or more first apertures of the first particle disc. The vacuum source is also configured to reduce air pressure within a second vacuum passage to couple the particles to one or more second apertures of the second particle disc. A rotation rate of the first particle disc is controllable to establish a particle spacing between the particles within the trench. A rotation rate of the second particle disc is controllable to expel the particles at a particle exit speed.

A particle delivery system of an agricultural row unit includes a particle disc configured to receive a plurality of particles from a particle metering and singulation unit, and a particle belt configured to receive each particle of the plurality of particles from the particle disc and to expel the particle to a trench in soil. The particle disc is configured to accelerate each particle of the plurality of particles to a target particle transfer speed.

A single disk fertilizer opener assembly for opening a trench in soil includes a frame support and a cutting disk for forming the trench. The cutting disk is coupled to an axle and rotates about the axle as the assembly moves in a working direction. The assembly also includes a first arm pivotally coupled to the frame support and the axle, and a second arm pivotally coupled to the frame support at a location spaced from the first arm. A bracket is coupled to the axle and the second arm, and a scraper is coupled to the bracket and disposed substantially perpendicularly to the working direction.

An agricultural implement, such as an agricultural seed planter, includes a number of ground engaging row units. The row units receive seed and/or other particulates and deposit the seed or particulates to the ground. The row unit can include row cleaners to aid in allowing a coulter or disk to create a furrow in a field. The seed is metered via a seed metering system and deposited in the furrow. A closing system closes the furrow after the seed has been deposited. To aid in access and mounting of the seed meter, it can be connected without connection to side components of a frame. In addition, the row cleaner and closing system can include mounting systems that allow better results and easier access to the same and other portions of the row units.
