    摘要： By providing an electronic control system in communication with a hydraulic system for adjusting an angle of smoothing tools of a harrow, the smoothing tools may be adjusted more quickly and on the go, including from a tractor cab, for optimum field leveling during a tilling session. The control system may include a hydraulic control valve in communication with a linear actuator. The linear actuator may be in communication with a slide bar disposed in a channel. By configuring multiple bars of a harrow to achieve an angle of rotation defined by the slide bar, the angle of rotation for smoothing tools of the harrow may be precisely controlled by the control system.

    摘要： A spring tooth harrow packer comprising a transversely extending draw bar which is wheel supported and which has a hitch extending forwardly therefrom for attachment to a tractor. A plurality of harrow sections are secured to the draw bar and are positioned rearwardly thereof which each of the harrow sections including a plurality of ground engaging spring teeth. A packer is mounted on the rearward end of each of the harrow sections and is pivotally secured thereto for selectively controlling the penetration depth of the teeth of the associated harrow section.

    摘要： A three wheeled, with equal weight distribution, vehicle with lesser torque capacity to the single front wheel relative to the torque capacity to each rear wheel and specifically designed to operate in a golf course sand-trap. A multi-unit sand-trap rake assembly adapted to be drawn by the vehicle. Each unit rake assembly including a carrier frame pivotally connected to the frame of the vehicle, two vertical support bars downwardly depending from the carrier frame and connected to a breaker bar that is drawn beneath the surface of the sand to break the bonds between the sand particles. The multi-unit assembly including a first row of smoothing plates pivotally connected to the carrier frames, a second row of dressing plates pivotally connected to the carrier frame, and side dressing plates each smoothing and dressing plate having a lower serrated edge for dressing the surface of the sand-trap.

    摘要： An improved hinge construction for interconnecting frames of an agricultural implement of the type wherein the frames may be lowered to a work performing position or elevated to a transporting position in which position they are additionally folded with respect to each other. The hinge includes two pintles, one for each frame, which pintles journal an elongated hinge member. One of the pintles is affixed to its associated frame such that the elongated member may cant as well as pivot relative to the frame to provide a relatively full range of movement of one frame relative to the other whether in work performing position or transporting position over varying types of terrain.
