摘要： An agricultural ground engaging machine (100) is disclosed. The agricultural ground engaging machine (100) comprising: a control system (314); a communication system (306) that receives an information map (358) that includes values of a characteristic corresponding to different geographic locations in a field; an in-situ sensor (308) that detects a value of a soil property corresponding to a geographic location in the field; a predictive model generator (310) that generates a predictive soil property model that models a relationship between characteristic values and values of the soil property based on the value of the soil property detected by the in-situ sensor (308) corresponding to the geographic location and a value of the characteristic in the information map (358) at the geographic location; and a predictive map generator (312) that generates a functional predictive soil property map of the worksite, that maps predictive values of the soil property to the different geographic locations in the worksite, based on the values of the characteristic in the information map (358) and based on the predictive soil property model. Furthermore, a method of controlling an agricultural ground engaging machine (100) is disclosed.

摘要： One or more techniques and/or systems are disclosed for air seeding using an agricultural seeder. The agricultural seeder includes an air seeder for an agricultural implement having a frame, a plurality of seeding units coupled to the frame, and a linkage coupling an arm to the frame, wherein the arm is coupled to a ground engaging member. The air seeder further includes an actuator having a piston and cylinder arrangement operationally coupled to the arm and configured to adjust a ground penetration depth of the ground engaging member. The piston and cylinder arrangement include a two-stage cylinder operable to change a height of the ground engaging member by movement of the two-stage cylinder to adjust the ground penetration depth of the ground engaging member.

摘要： A device detects a trigger to dispense a product at a dispense point using a tool operably coupled to a tractor. In response to detecting the trigger, the device determines a delay time between commanding the tool to dispense the product and the product actually being dispensed, and determines a release point based on operating parameters of the tractor, the release point being a point at which the tractor is predicted to be an amount of time away from the dispense point equal to the delay time. The device determines that the tractor has reached the release point, and commands the tool to dispense the product, where the product reaches the dispense point based on the delay time.
