A system includes an engine, a transmission driven by the engine, and a controller. The controller is configured to receive a speed input, receive feedback indicative of a load of the engine at a current engine speed, compare the load to a predetermined load threshold at the current engine speed, determine an expected engine speed based at least on the current engine speed, a current gear ratio, and an expected gear ratio, determine an estimated engine power at the expected engine speed and a current engine power at the current engine speed, and command a gear downshift when the load is greater than or equal to the predetermined load threshold and when the estimated engine power is greater than the current engine power.

An agricultural implement includes: a center frame defining a travel axis; a tool bar connected to the center frame and extending transversely to the travel axis; a first row unit having a first parallel linkage defining a first linkage angle relative to the tool bar; a first angle sensor associated with the tool bar and the first parallel linkage and configured to output a first linkage angle signal corresponding to the first linkage angle; an actuator linked to the first row unit and configured to adjust the first linkage angle; and a controller operationally coupled to the first angle sensor and the actuator. The controller is configured to: determine the first linkage angle; compare the first linkage angle to a preset linkage angle; and activate the actuator to adjust the first linkage angle to the preset linkage angle if the first linkage angle deviates from the preset linkage angle.

Disclosed is a two-component power take-off (PTO) coupling system for efficient and simplified attachment of implements to a power take-off system of a tractor or other prime mover, having a first component to be attached to the PTO shaft of the tractor or other driver and a second component attached to the implement to be coupled. The coupling system serves to eliminate the difficult task of attaching or detaching a power shaft on a rotary driven farm implement such as a rotary cutter, tiller, generator, pump, etc. to tractor power take off (PTO) or any other driver that has an auxiliary splined power out-put shaft. It is designed for any application in any industry that requires frequent connecting or disconnecting of a rotating shaft to transfer power or torque. The coupling system can accommodate two different series PTO shaft types for example, if the implement has a type two (2) shaft but the owner's tractor is a type one (1) the coupling system can be adapted to accommodate both.

A towed agricultural machine includes a converter, configured to convert a first voltage potential generated by a generator to a second voltage potential. The second voltage potential powers a component of the towed agricultural machine. Further, the towed agricultural machine also includes a switch that senses the absence of the second voltage potential from the converter and switches to powering the subcomponent with a second voltage potential received from a source external to the towed agricultural machine.

A kill switch including a switch assembly. When the switch assembly moves from a switch first configuration to a switch second configuration with the switch assembly operatively connected to a controller of a tractor, a kill electrical signal is provided to the controller to stop the tractor powering a power take-off thereof. A cord is securable to the switch assembly and to the piece of machinery to extend along a rotary drive shaft between the tractor and the piece of machinery. A switch actuating element extends from the cord, the switch actuating element being removably securable to the switch assembly. In the switch first configuration with the switch actuating element secured to the switch assembly, the switch actuating element maintains the switch assembly in the switch first configuration. When the switch actuating element is removed from the actuating element receiving portion, the switch assembly moves to the switch second configuration.
