Abstract
A soil cultivating machine has soil working members that are driven about upwardly extending axes. Each working member has radial arms and a tined cultivating rotor is pivotably connected to the outer end of each arm. Each cultivating rotor is freely rotatable about an upwardly extending axis and an adjustment device can be set to vary the position of the cultivating rotor about the pivot connection to its corresponding arm to change the working positions of the tines. The cultivating rotor can use different tines depending on the condition of the ground being worked.
Claims15
A soil cultivating machine comprising a frame and at least one soil working member being supported on said frame, said soil working member being rotatable about at least one upwardly extending axis and driving means connected to rotate said soil working member about that axis, tined cultivating means being rotatably mounted on said soil working member and spaced from said axis, and said cultivating means being freely rotatable about a further axis, an adjusting device connecting said cultivating means to said member and said cultivating means being pivotable to a plurality of freely rotatable working positions above a pivot shaft of said adjusting device, said pivot shaft extending in a non parallel direction with respect to the axis of rotation of the soil working member, a support connected to said soil cultivating means and journalled to turn about said pivot shaft, said cultivating means being fixable in any one of a plurality of different working positions relative to the remainder of said soil working member about said pivot shaft, a part and a further similar part being positioned one on each side of an arm of said soil working member and pivotable on said arm, said part and further part being fixable in a number of chosen positions with respect to said arm.
A soil-cultivating machine comprising a frame and at least one soil-working member being supported on said frame, said soil-working member being rotatable about at least one upwardly extending rotary axis and driving means connected to rotate said soil-working member about that axis, cultivating means being rotatable mounted on said soil-working member and spaced from said rotary axis, sid cultivating means being freely rotatable about a further, upwardly extending axis that is defined by a shaft, said cultivating means comprising a plurality of tines having elongated upper ends that extend upwardly, means adjusting the relative position of said shaft and the working position of said cultivating means, said soil-cultivating means comprising a plurality of arms that are inclined downwardly and away from said shaft, the outer free ends of said arms having corresponding downwardly extending tines secured thereon and said ajustment means including a pivot that is positioned nearer said rotary axis than said shaft of the cultivating means.
