Abstract:
1. A farm implement adjustment mechanism adapted to be coupled to a field apparatus secured to a motive power source that is pulled in a forward direction over a field to treat soil, the farm implement adjustment mechanism is configured to adjust the position a farm implement with respect to the soil, the farm implement adjustment mechanism comprising: a height adjuster coupled to the farm implement and the field apparatus, the height adjuster configured to move the farm implement in a first direction and a second direction that is the opposite of the first direction, the height adjuster having a base member that is adapted to accept the farm implement; the height adjuster having a generally vertical support tube coupled to the base member and a generally vertical housing tower that is adapted to accept at least a portion of the support tube within the housing tower; the height adjuster further including a generally vertical threaded rod positioned within the support tube, to permit adjustment of the support tube with respect to the housing tower; an electric motor; a transmission coupled to the electric motor; a power transfer unit having a flexible outer casing and a flexible shaft positioned within and rotatable with respect to the flexible outer casing, the power transfer unit being coupled to the threaded rod at a first end and to the transmission at a second end, the power transfer unit configured to flex to allow the mounting of the electric motor in multiple positions on the field apparatus with respect to the height adjuster; and wherein rotation of the electric motor in a first rotational direction causes the farm implement to move in the first direction and rotation of the electric motor in a second rotational direction causes the farm implement to move in the second direction.
