Patent number: 11665995Abstract: The controller that receives at least one sensor signal indicative of a measured profile of a particulate material within a storage tank of an agricultural system. The controller also determines whether a variation between the measured profile and a target profile is greater than a threshold value. The controller outputs a first output signal to a user interface indicative of instructions to inform an operator of a profile variation, outputs a second output signal to an agitator indicative of activation of the agitator, or a combination thereof, in response to determining that the variation between the measured profile and the target profile is greater than the threshold value.Type: GrantFiled: February 1, 2019Date of Patent: June 6, 2023Assignee: CNH Industrial Canada, Ltd.Inventor: Graham Douglas Stuart

Patent number: 11553640Abstract: An agricultural implement wear monitoring system that monitors a first component of an agricultural implement. A sensor detects and emits a signal indicative of a first geometric dimension of the first component and/or a second geometric dimension of the first component relative to a second component. A controller couples to the sensor. The controller monitors the first geometric dimension and/or the second geometric dimension, and in response to a detected change in the first geometric dimension and/or the second geometric dimension determines a remaining service life of the first component.Type: GrantFiled: June 11, 2019Date of Patent: January 17, 2023Assignee: CNH INDUSTRIAL CANADA, LTD.Inventors: Matthew Stuart Naylor, Graham Douglas Stuart
