Abstract: The active coulter system includes a pivotable support structure that vertically adjusts the position of an active coulter component to compensate for changes in the contour of a target field. In the preferred embodiment, a proximity sensor and an associated controller are in electronic communication with a linear actuator assembly. Based on data from the proximity sensor, the controller sends electronic instructions to the linear actuator assembly to automatically move the active coulter component vertically. The system also optionally includes a torque/speed sensor that can operate independently to control the torque and/or power supplied to the active coulter component, or the sensor can interface with the controller and anticipate changes in power needs and increase/decrease power before the operation of the active coulter component is affected.

Abstract: A controller is connected to a pressure sensor. The controller controls a regulator of a sub-pump in accordance with a pressure signal from the pressure sensor, detects an output of a main pump, and controls an output of an electric motor according to the output of the main pump based on a table stored beforehand.

Abstract: A seed meter for a planting machine is provided with an adjustable drive coupling between the seed meter and the planting machine main drive. The drive coupling includes a drive member connected to the planter drive and a driven member coupled to the seed meter shaft. The drive member and driven member are drivingly engagable with one another and held into the engaged position by a biasing member. The drive member and driven member are selectively movable relative to one another to a disengaged position, enabling adjustment of the seed meter relative to the drive by rotation of the meter shaft. Once released, the coupling self-engages.

Abstract: The children's vehicle, particularly pedal vehicle, is characterized by a sweeping device which is provided with at least one brush and is detachably connectable to the children's vehicle. For driving the brush roller a driver wheel is arranged that in the operative position of the sweeping device is positioned on the ground.

Abstract: A seeding machine having a plurality of seed meters receiving rotary input from a common input shaft. First and second gearboxes respectively connect the common rotary input to individual seed meters. A flexible drive extends from the gearbox adjacent the common rotary input to the seed meters. Spring clutches, normally connected, are electrically actuated to disengage the drive to the individual seed meters. The clutches may be integrated in the gearbox adjacent the rotary drive or the gear box for the individual seed meters.

Abstract: A drive apparatus has a first and second shaft rotatably mounted on the agricultural fertilizer implement. A drive wheel is fixed to the first shaft and an output wheel fixed to the second shaft. There are a plurality of wheels coupled to the first shaft and a plurality of wheels of varying sized fixed to the second shaft. A flexible connecting means is trained between a pair of selected wheels on the first and second shafts. A drive means rotates the drive wheel. A connecting means couples output wheel to the metering device. An engaging means is coupled to each of the plurality of wheels located on the first shaft coupling the selected wheel on the first shaft with the first shaft so that the wheel will rotate with the first shaft. There is also a control means that allows a user to selectively activate one of the engaging means located on the first shaft. When one of the engaging means is activated, one of the plurality of wheels is coupled to the first shaft and begins to rotate with the first shaft.

Abstract: A compact drive assembly including a flexible drive for transmitting power from a ground engaging wheel or wheels to a driven mechanism such as a seed meter on an implement. A set of cross helical spur gears are mounted in an enclosed case. The input gear is clamped to the ground engaging wheel shaft, and the output gear is fastened to a shaft which drives a flexible cable. The flexible cable is enclosed in a flexible housing and is connected to the remainder of the drive train.

Abstract: A power tillage device is provided having a passive rolling coulter as the prime mover for a power tillage blade which is carried in the lead of the coulter on a transfer case mounted as a radius arm on the counter shaft. The tillage blade rotates in the opposite direction from the coulter and is designed for optimum efficiency for shearing and lifting soil from a furrow.

Abstract: A drive roller for driving feeding and metering mechanisms for seed and fertilizer of a grain drill which utilizes a drive roller riding against a pair of castering frame support wheels that are independent of the press wheel assemblies for the grain drill. The roller provides satisfactory drive where individual depth control of each of the furrow openers is utilized. The drive is adapted for use on a wide variety of different drills.
