Embodiments relate to apparatuses, methods and computer programs for controlling a machine. The apparatus is suitable for a mobile communication device for providing a sensor input signal to a machine control entity to control a machine. The apparatus comprises one or more sensor modules for providing first user input sensor data and second user input sensor data. The apparatus further comprises a control module configured to determine the sensor input signal based on the first user input sensor data and the second user input sensor data. The control module is further configured to provide the sensor input signal for sensor data processing to the machine control entity to control at least one of a force transmission interface of the machine for an external component and an engine of the machine via an interface.

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.

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.

A data propagation system stores operator/machine/implement combinations, and corresponding settings data indicative of settings on the machine or implement for the corresponding combination. When a machine is connected to an implement, an identity of an operator is detected, along with an identity of the machine and an identity of the implement. The data propagation system determines whether settings data is available for that operator/machine/implement combination. If so, the settings data is obtained and the machine and implement are automatically controlled based upon the retrieved settings data.

One or more techniques and/or systems for application of a supplemental downward force to a ground working implement. A mechanical advantage from a lever arm can be utilized to apply supplemental downforce to a ground working implement. A biasing force can be applied to the lever arm by a spring assembly at various locations. Moving the spring assembly along the lever arm can vary the amount of downward force applied by the lever arm to ground working implement. In some implementations, moving the spring assembly to a different end of the lever arm applies an upward force to a coupled ground working implement.

A pivot system for a rotating agricultural tool includes a bearing assembly has an inner bearing race and an outer bearing race. The pivot system also includes a shaft having a first longitudinal end and a second longitudinal end. The shaft has an angled surface extending from the first longitudinal end to the second longitudinal end. The angled surface has a plurality of points of contact. The inner bearing race contacts the plurality of points of contact to enable the bearing assembly to pivot about a transverse axis that extends perpendicularly to the longitudinal axis of the shaft.
