A cutting head for a sod harvester is configured to counterbalance forces that are generated during operation. When the cutting head is operated, the cutting blade oscillates to sever sod from the ground. This oscillation of the cutting blade generates significant horizontal vibration forces that are transferred to the cutting head and other components of the sod harvester. The cutting head can include a crankshaft assembly with counterweights that are designed to balance these horizontal vibration forces. The cutting head can also include a countershaft assembly with counterweights that are also designed to balance these horizontal vibration forces while also balancing vertical vibration forces that the counterweights of the crankshaft assembly create.

In one aspect, a system for controlling the operation of a seed-planting implement may include a ground-engaging tool and an actuator configured to adjust an operating parameter of the ground-engaging tool. Furthermore, the system may include a controller configured to control the operation of the seed-planting implement such that a primary crop is planted in a field as the seed-planting implement is being moved across the field. Additionally, the controller may be configured to determine a density of a cover crop present within the field. Moreover, the controller may be configured to determine an adjustment to be made to the operating parameter of the ground-engaging tool based on the determined density. In addition, the controller may be configured to control the operation of the actuator to execute the adjustment of the operating parameter.

A coupling device for attaching a power lift of a tractor to an attachment includes a link mounting region having coupling units for the articulation of an upper link and two lower links of the power lift, and an apparatus mounting region for fixing the attachment. A coupling unit assigned to the upper link is movable in a translatory manner in a vertical direction running perpendicular to a transverse direction. The coupling units are movably disposed on a device base of the coupling device, and the coupling units assigned to the two lower links are movable in a translatory manner in the transverse direction.

The present disclosure refers to a method for operating a user terminal (7) of an agricultural machine, comprising providing a user terminal (7) in a control system (3) of an agricultural machine, the user terminal (7) connected to a power supply and configured to transmit, through a control bus (6), control signals to functional elements (10a; 10b) of the agricultural machine; enabling operation of the user terminal (7), after a period of time the user terminal was turned-off before, comprising enabling a user control mode of operation of the user terminal (7); running software applications in the user terminal (7); enabling a display device of the user terminal (7); and enabling the control bus (6), thereby, operating the control bus (6) in a bus control mode allowing for transmission of the control signals through the control bus (6); controlling operation of one of the functional elements (10a; 10b) of the agricultural machine in the user control mode of operation; in response to a user input, generating present control signals; transmitting the present control signals to the control unit assigned to the one of the functional elements (10a; 10b) through the control bus (6); and operating the functional elements (10a; 10b) according to the present control signals; disabling the user control mode of operation and enabling a standby mode of operation for the user terminal (7), comprising continuing with running one or all of the software applications in the user terminal (7); disabling the display device of the user terminal (7); and disabling the control bus (6); and re-enabling the control mode of operation for the user terminal (7). Further, an agricultural machine is provided. (FIG. 1)

Systems, methods and apparatus for adjusting the depth of a trench opened by a row unit of an agricultural planter. The row unit includes a trench depth adjustment assembly configured to modify the furrow depth. In one embodiment, the depth adjustment assembly may include a gear box having one or more gears which engage with a gear rack. The gear box may be pivotally connected to a depth adjustment body supporting a rocker that adjusts upward travel of gauge wheel arms. 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.
