Patent number: 9664249Abstract: A method and system for controlling operation of a tractor and/or agricultural implement towed by the tractor is provided. A vibration sensor is mounted to the agricultural implement to detect the magnitude of vibration, or bounce, on the agricultural implement. Because the magnitude of the vibration is a function of several operating parameters including, but not limited to, the speed at which the tractor is travelling and the downward pressure applied to the agricultural implement, one or more additional sensors are provided to monitor these operating parameters. Each of the sensors generates a feedback signal and transmits it to the controller. The controller is configured to generate a reference signal to control an actuator as a function of the magnitude of vibration and the measured operating parameter. The actuator receiving the reference signal is configured to control operation of the tractor or agricultural implement to reduce the magnitude of vibration.Type: GrantFiled: January 11, 2013Date of Patent: May 30, 2017Assignee: CNH Industrial Canada, Ltd.Inventor: Trevor Kowalchuk

Patent number: 9615499Abstract: An agricultural implement has a depth control system in which a position sensor directly measures linear translation of a hydraulic cylinder that lifts and lowers a work unit on an implement frame to set and adjust the depth of the work unit without the use of a rockshaft. The position sensor may be positioned adjacent to or integrally formed with the hydraulic cylinder, and provides a voltage to a controller remote from the implement. The controller automatically adjusts the flow of hydraulic fluid to and from the hydraulic cylinder to maintain the depth of each work unit at an operator-selected level and can be used to calibrate the actual position of multiple work units relative to the frame and to one another.Type: GrantFiled: December 3, 2014Date of Patent: April 11, 2017Assignee: CNH Industrial Canada, Ltd.Inventors: Trevor Kowalchuk, Nick Ryder

Patent number: 9451740Abstract: A singulation-style seeding system is provided that may include planter row units arranged on a drill that may have a front rank and a back rank. The planter units may singulate and deliver seeds from a first segment of the drill, which may correspond to one of the front and back ranks. A high-volume fertilizer may be delivered from a second segment of the drill, which may correspond to the other one of the front and back ranks and may be delivered at a relatively high delivery rate. A starter fertilizer may be delivered at a relatively lower delivery rate at or near seed furrows.Type: GrantFiled: March 15, 2013Date of Patent: September 27, 2016Assignee: CNH Industrial Canada, Ltd.Inventor: Trevor Kowalchuk

Publication number: 20160143213Abstract: The present invention is directed to a seed discharge system is that employs a pair of rotating belts spaced from one another to receive the seeds from a seed metering device and to direct the seeds into the desired location within a trench over which the discharge system is positioned. The seeds are received within a gap formed between the belts and are clamped and held between the belts as the belts move, consequently moving the seeds from the seed metering device to the discharge opening of the discharge system. The constant engagement of the seeds with the belts through the discharge system prevents the seeds from bouncing, thereby maintaining a constant residence time for the seeds within the discharge system.Type: ApplicationFiled: November 26, 2014Publication date: May 26, 2016Inventor: Trevor Kowalchuk

Patent number: 9232690Abstract: A method and system for controlling an air cart to deliver custom blends of fertilizer to a field is disclosed. A farmer purchases base nutrients which are mixed together during delivery to the field. An air cart having multiple compartments is selected according to the number of base nutrients and/or seed to be delivered. Metering units associated with each compartment control the rate at which product is delivered. An operator defines a desired blend of fertilizer and identifies each of the base nutrients loaded into the air cart. The controller generates control signals output to each metering unit to control the rate at which product is delivered according to the desired blend of fertilizer. Thus, a farmer may purchase and store base nutrients rather than various blends of fertilizer and create multiple customized blends as needed according to the area and the type of seed to be planted.Type: GrantFiled: November 13, 2012Date of Patent: January 12, 2016Assignee: CNH Industrial Canada, Ltd.Inventor: Trevor Kowalchuk

Publication number: 20140303834Abstract: A sectional control apparatus and method prompts the operator of an implement when the implement, or portion thereof, is traversing over land that has already been seeded and/or disturbed. The apparatus includes a GPS or GNSS receiver that communicates with a GPS or GNSS system and a controller that maps movement of the implement so that real-time positional data for the implement can be compared to the movement map. When the position of the implement, or portion thereof, is detected as moving over previously seeded and/or disturbed land, the controller activates an alert mechanism in the operator cab of the implement to notify the operator that sectional control, i.e., shutting down metering of product or raising the tool bar, needs to be implemented.Type: ApplicationFiled: June 24, 2014Publication date: October 9, 2014Inventor: Trevor Kowalchuk

Patent number: 8275525Abstract: A disc opener unit for an agricultural implement has a down pressure adjustment device that automatically adjusts the amount of down pressure applied on a furrowing disc based on strain measurements taken by a strain gauge or load cell. The strain gauge, which may be mounted to an arm that is used to set the position of a depth setting gauge wheel, provides feedback to a processor that in turn controls the amount of hydraulic fluid in a hydraulic cylinder to adjust the down force applied on the disc. The amount of down pressure is therefore adjusted in substantially real-time in response to changes in field conditions, which improves furrow depth consistency and reduces wear on the gauge wheel and its components.Type: GrantFiled: June 22, 2010Date of Patent: September 25, 2012Assignee: CNH Canada, Ltd.Inventors: Trevor Kowalchuk, Robin B.

Patent number: 8220235Abstract: A cornhead row unit is provided including first and second longitudinally extending stripper plates mounted on a frame and having opposed stripping edges which define a gap between them. The frame further includes a resilient device arranged and disposed to adjustably transversely urge the first stripper plate on the frame toward the second stripper plate to vary the width of the gap. An adjusting arrangement connecting the frame and the second stripper plate selectably and transversely moves the second stripper plate with respect to the first stripper plate to vary the width of the gap.Type: GrantFiled: January 19, 2010Date of Patent: July 17, 2012Assignee: CNH America LLCInventor: Trevor Kowalchuk
