  • Patent number: 12207578
    Abstract: A finishing tool control system for an agricultural implement may include a controller communicatively coupled to a first and a second sensor. The controller is configured to control a height of a finishing tool above a soil surface. Further, the first sensor is configured to output a signal indicative of a height of a main frame of the agricultural implement above the soil surface. In response to determining that a height increase of the main frame exceeds a threshold height adjustment, the controller increases the height of the finishing tool. The second sensor is configured to output a signal indicative of the height of the finishing tool of the finishing assembly above the soil surface. Moreover, in response to determining that a height of the finishing assembly above the soil surface is less than a threshold value, the controller increases the height of the finishing tool.

  • Patent number: 4670971
    Abstract: A method of manufacturing an armature winding conductor including fusing brazing alloy onto the surface of the conductor, and, ensuring that the dimensions of the conductor, in the region carrying the alloy, are such that the conductor can pass through the slots of the armature core with which the windings are to be associated in use. The conductor is cut to length and bent to fit the armature either before or after the fusion step.
