A seed tube guard for agricultural planters is cast from a high-chrome cast-iron alloy or manufactured from other wear-resistant material. The seed tube guard has a leading front surface, a trailing rear surface, and respective right and left surfaces. A fluid delivery channel is integrated within the body of the seed tube guard between the leading front surface and the trailing rear surface, and between the right and left surfaces. The fluid delivery channel has an entrance and an exit with the exit located below and rearward of the entrance for delivering fluid into a seed furrow ahead of a seed tube exit.

One row unit for an agricultural implement includes a ground engaging tool configured to penetrate soil and to form a furrow in the soil. The row unit also includes gauge wheels disposed adjacent to the ground engaging tool and configured to enable the ground engaging tool to penetrate the soil at a selectable penetration depth. Each of the gauge wheels extends substantially parallel to a direction of travel of the row unit.

A soil apparatus (e.g., seed firmer) having a locking system is described herein. In one embodiment, the soil apparatus includes a lower base portion for engaging in soil of an agricultural field, an upper base portion, and a neck portion having protrusions to insert into the lower base portion of a base and then lock when a region of the upper base portion is inserted into the lower base portion and this region of the upper base portion presses the protrusions to lock the neck portion to the upper base portion.

A power seeder may include a frame, one or more wheels, one or more blades capable of cutting into soil, an engine capable of powering the one or more blades, and a seed hopper. The seed hopper may have an opening capable of dispensing seed located forward of the one or more blades. The one or more blades may rotate in an opposite direction to a forward rotation of the one or more wheels. 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.

In one aspect, a system for controlling the operation of a residue removal device of a seed-planting implement may include a residue removal device configured to remove residue from a path of the seed-planting implement. The system may also include a sensor configured to capture data indicative of a residue characteristic associated with a portion of the field within a detection zone positioned forward of the residue removal device relative to a direction of travel of the seed-planting implement. Furthermore, the system may include a controller communicatively coupled to the sensor. As such, the controller may be configured to monitor the residue characteristic associated with the portion of the field within the detection zone based on data received from the sensor. Additionally, the controller may be further configured to control the operation of the residue removal device based on the monitored residue characteristic.

An agricultural seeder implement includes a seed boot connected directly to an opener having a leading extremity and a trailing extremity. The seed boot and the opener form a channel and an outlet. The channel extends forwardly from an inlet of the seed boot proximate to the trailing extremity of the opener to the outlet behind the leading extremity of the opener. The opener is for being pulled for cutting a furrow in the ground by the leading extremity ahead of the outlet, and the channel is for guiding a stream of air-driven seed forwardly therethrough from the inlet and into the furrow through the outlet directed downwardly in the furrow.

A unit (UO) for the processing ground (T), comprises at least a first group (G1, D3) for supporting rotating cutting disk means (D) adapted to realize grooves (S) in said ground (T); at least a second group (G2) for supporting plowshare means (V, E) adapted to realize, in correspondence of said grooves (S), cuts (Z) below the surface of said ground (T); and mechanical coupling means (M2) for dynamically connecting said second group (G2) to said first group (G1, D3).
