  • Patent number: 9694848
    Abstract: A High Performance Steering System for amplifying the turning motion of an axle as the turning motion is applied to wheels or tracks at the outer ends of the axle. The present invention generally includes a support member such as an axle which is secured underneath the frame of a vehicle such as a garden tractor or automobile. The support member includes a fixed post and an outer post for each wheel that is steered. Wheels or tracks are connected to the outer posts, such as by mounts. Rotation of the support member imparts forces through sprockets, gears, pulleys, tie rod linkages, or the like to amplify the turning motion of the support member as it is applied to the outer post. The amount of such amplification of turning motion between the support member and outer posts may be varied with differing size ratios of the sprockets, gears, or pulleys.

  • Patent number: 7472658
    Abstract: The present disclosure includes various methods and devices for planting. One method embodiment includes providing a planting device having a frame, the planting device including a generally vertically oriented barrel and a ram slidable within the barrel for propelling a slip having a length placed therein. The method includes accelerating the ram, contacting the slip with the ram, and propelling the slip to a velocity such that the momentum of the slip is sufficient to fire the slip through an unprepared ground surface such that the slip penetrates the ground surface to a depth of at least 80% of the length of the slip.
