In another embodiment, the depth adjustment assembly may include a depth adjustment arm having a screw receiver that cooperates with a driven screw that adjusts the position of the depth adjustment arm acting on the gauge wheels to adjust trench depth.

The invention relates to a method for operating an agricultural machine having a tractor (1) and an implement (2) hitched to the tractor (1), the method comprising connecting a control device (12) provided on the tractor (1) to a data bus (6), wherein the control device (12) is configured to process data indicative for a plurality of implement operation parameters assigned parameter identifiers P1 to Pn (n 2); connecting a control unit (9b) provided on the implement to the data bus (6), wherein the control unit (9b) is assigned to at least one functional element of the implement (2); and establishing data communication between the control device (12) and the control unit (9b) through the data bus (6), comprising, in response to connecting the control unit (9b) to the data bus (6), transmitting a response data message from the control unit (9b) to the control device, the response data message indicating the control unit (9b) being configured to provide present parameter values for only a subset of implement operation parameters assigned parameter identifiers P1 to Pm (m<n), but not for a subset of remaining implement operation parameters assigned parameter identifiers Pm+1 to Pn. Further, in response to receiving the response data message in the control device, future data collecting messages transmitted from the control device (12) to the control unit (9b) are limited to requesting present parameter values for the subset of implement operation parameters assigned parameter identifiers P1 to Pm only, and the future data collecting messages transmitted to the control unit (9b) are prevented from requesting present parameter values for the subset of the remaining implement operation parameters assigned parameter identifiers Pm+1 to Pn. Furthermore, an agricultural machine having a tractor (1) and an implement (2) hitched to the tractor (1) is provided.

A combination of a tractive machine and plow, has a driver assistance system having an input/output unit. The plow is adjustable with machine parameters, wherein a portion is manually adjustable and/or automatically adjustable by means of the tractive machine. A plow adjust assistant determines in a dialog with an operator in a plurality of dialog steps, optimized machine parameters of the plow and/or of the tractive machine that are to be adjusted. The plow adjust assistant automatically adjusts a portion of the machine parameters determined in the first dialog step and/or gives the operator a portion for adjusting and determines further optimized machine parameters of the plow based on these machine parameters and gives these further optimized machine parameters of the plow to the operator for adjustment of the plow in a second dialog step and/or automatically adjusts them at the plow.

A control system to control a work machine and a traveling vehicle traveling with the work machine, includes a first communication device and a second communication device each of which controls operation of the traveling vehicle and at least one of which includes an authenticator to authenticate the work machine by communicating with a third communication device to control operation of the work machine, and a notifier to notify the other one of the first communication device and the second communication device that the authenticator succeeded in authentication, the first communication device and the second communication device each being prohibited, unless the authenticator succeeds in authentication, from at least controlling operation of the traveling vehicle in accordance with information sent from the third communication device.

A shank assembly for an agricultural tillage implement including a support arm, a shank connected to the support arm, a point connected to the shank, and a float monitoring system. The float monitoring system includes a first sensor for sensing a home position, a second sensor connected to the support arm and configured for sensing an angular position of the support arm relative to the frame of the agricultural tillage implement, and an electronic control unit operably connected to the first sensor and the second sensor. The electronic control unit is configured for comparing the home position and the angular position of the support arm and determining a float of the shank as the shank is towed in a forward direction of travel.
