20130180742 | SOIL MONITORING SYSTEM - A soil monitoring system is provided that includes a sensing shank, and a first sensor coupled to a leading edge of the sensing shank. The first sensor is configured to output first signals indicative of a pressure exerted on the first sensor by soil as the sensing shank is driven through the soil along a direction of travel. The soil monitoring system also includes a frame forming a channel oriented in a substantially vertical direction relative to a surface of the soil, and a carrier coupled to the sensing shank and disposed within the channel. The soil monitoring system further includes an actuator extending between the frame and the carrier. The actuator is configured to linearly drive the carrier in a reciprocating motion to vary a penetration depth of the sensing shank within the soil. | 07-18-2013 |
20130248214 | MANUAL BACKUP SYSTEM FOR CONTROLLING FLUID FLOW TO CYLINDERS WITHIN AN AGRICULTURAL IMPLEMENT - An agricultural implement system is provided that includes a down force cylinder configured to apply a downward force to a row unit, a depth control cylinder configured to vary a penetration depth of a ground engaging tool of the row unit, a press wheel cylinder configured to vary contact force between a press wheel and a soil surface, a closing disk cylinder configured to vary contact force between a closing disk and the soil surface, a residue manager cylinder configured to vary contact force between a residue manager and the soil surface, or a combination thereof. The agricultural implement system also includes an electronic control unit configured to automatically regulate a pressure within the cylinders, and a manual backup system configured to facilitate manual pressure adjustment of the cylinders. | 09-26-2013 |
20130319698 | AGRICULTURAL IMPLEMENT WITH COMBINED DOWN FORCE AND DEPTH CONTROL - An agricultural implement system is provided that includes a down force cylinder configured to apply a downward force to a row unit, and a depth control cylinder configured to vary a penetration depth of a ground engaging tool of the row unit. The agricultural implement system also includes a valve assembly in fluid communication with the down force cylinder and the depth control cylinder. The valve assembly is configured to automatically adjust the downward force by varying fluid pressure within the down force cylinder based on fluid pressure within the depth control cylinder. | 12-05-2013 |
20130325267 | AGRICULTURAL IMPLEMENT WITH COMBINED DOWN FORCE AND DEPTH CONTROL - An agricultural implement system is provided that includes a down force cylinder configured to apply a downward force to a row unit, and a depth control cylinder configured to vary a penetration depth of a ground engaging tool of the row unit. The agricultural implement system also includes a valve assembly in fluid communication with the down force cylinder and the depth control cylinder. The valve assembly is configured to automatically adjust the downward force by varying fluid pressure within the down force cylinder based on fluid pressure within the depth control cylinder. | 12-05-2013 |
20140076219 | Low Torque And Vacuum Seed Meter - A seed meter is provided for use with a row crop planter or seed planter that includes a seed disk assembly that rotates within a meter housing cavity and that has a seed disk assembly cavity in which a vacuum pressure is applied for pulling seeds into seed pockets of a seed disk of the seed disc assembly. The vacuum pressure is applied to the seed disk assembly by pulling a vacuum airflow through a spindle that supports the seed disk assembly. A wiper seal is arranged in a fixed position within the seed disk assembly cavity and seals against the seed disk assembly as a support plate and seed disk of the seed disk assembly rotate over the wiper seal, so that the wiper seal creates a boundary between a vacuum zone and a non-vacuum zone inside of the seed disc assembly cavity. | 03-20-2014 |
20140182493 | Low Torque And Vacuum Seed Meter - A seed meter is provided for use with a row crop planter or seed planter that includes a seed disk assembly that rotates within a meter housing cavity and that has a seed disk assembly cavity in which a vacuum pressure is applied for pulling seeds into seed pockets of a seed disk of the seed disk assembly. The vacuum pressure is applied to the seed disk assembly by pulling a vacuum airflow through a collector of a spindle-mounted hub support that is fluidly connected through a face seal arrangement with a hub face of the seed disk assembly. | 07-03-2014 |
20140182495 | Seed Delivery System - A seed delivery system is provided that includes a row crop seed planter having a seed meter that can pneumatically deliver seeds to the agricultural field at a rearward velocity that matches a forward velocity of the planter. The seed meter may include a positive pressure source that pressurizes the seed meter and creates an airflow out of a seed tube of the seed meter that carries the individual seeds out of the seed tube at a rearward velocity that is automatically adjusted to match a forward velocity of the seed planter and tractor. | 07-03-2014 |
20140182496 | Low Torque And Vacuum Seed Meter - A seed meter is provided for use with a row crop planter or seed planter that includes a seed disk assembly that rotates within a meter housing cavity and that has a seed disk assembly cavity in which a vacuum pressure is applied for pulling seeds into seed pockets of a seed disk of the seed disc assembly. The vacuum pressure is applied to the seed disk assembly by pulling a vacuum airflow through a spindle that supports the seed disk assembly. A wiper basket is arranged in a fixed position within the seed disk assembly cavity and seals against the seed disk assembly as a support plate and seed disk of the seed disk assembly rotate over the wiper basket, so that side walls of the wiper basket create a boundary between a vacuum zone and a non-vacuum zone inside of the seed disc assembly cavity. | 07-03-2014 |
