A cultivating machine has one or more working members that are driven to rotate about upwardly extending axes. Each working member is connected to a drive transmission to turn and, spaced apart soil working members mounted for free rotation about respective axes, are moved through the soil. At least two of the soil working members are different from one another and capable of workingthe soil in different ways. One member can be a group of tines that are freely rotatable about an upwardly extending axis and an adjacent member can be a disc that rotates about a horizontal axis. Each member includes a stub shaft that is journalled in a universal mount so that the members can be released and exchanged to meet varying soil conditions. The mount has a pivot connection and a setting device to retain the soil working member at various working angles. Also, the stud shaft is adjustable within a sleeve of the mount.
A soil cultivating machine comprising a frame and at least one soil working member mounted 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 said axis, at least one soil cultivating means on said soil working member and said cultivating means being freely rotatable on that member, said cultivating means being releasably secured in a mount of said soil working member and turnable about pivot connections, including a first pivotal axis and a second pivotal axis, relative to the soil working member, said cultivating means being adjustable about both pivotal axes and fixable in any one of a plurality of different working positions relative to either said pivotal axes, said first pivotal axis being nearer to said upwardly extending axis than said second pivotal axis and the latter extending in an upward direction.
A soil cultivating machine comprising a frame and at least one soil working member mounted on said frame, said soil working member being rotatable about an upwardly extending axis and driving means connected to rotate said soil working member about said axis, said soil working member being a rotor that supports a plurality of spaced apart soil cultivating means and said cultivating means being releasably secured in a corresponding universal mount of said rotor, said soil cultivating means comprising a first cultivating member and a second, different, cultivating member, the first and second cultivating members being interchangeable with one another and freely rotatably about respective axes of rotation, each cultivating member including a stub shaft that is releasably secured in a corresponding mount, and said stub shaft having a portion that is received and held in a sleeve of said mount, said portion having a tapering form and an upper end with fastening means that fixes the stub shaft portion in said sleeve.
A soil cultivating machine comprising a frame and at least one soil working member mounted on said frame, said soil working member being rotatable about an upwardly extending axis and driving means connected to rotate said soil working member about said axis, at least one soil cultivating means being mounted for free rotation on said soil working member, said cultivating means being releasably secured in mounting means on said working member and said mounting means comprising a first pivotal axis and a second pivotal axis, said cultivating means being adjustable about both pivotal axes and fixable in any one of a plurality of different working positions relative to either picotal axis, said cultivating means being journalled to said mounting means with a stub shaft and the longitudinal center line of at least part of said stub shaft on which said cultivating means is mounted, constituting said second pivotal axis, said cultivating means and said stub being turnable about said longitudinal center line and fixable in different angular positions, about said center line.
A soil cultivating machine comprising a frame and at least one soil working member mounted on said frame, said working member being rotatable about an upwardly extending axis and driving means connected to rotate said working member about that axis, at least one soil cultivating means mounted on said working member and said cultivating means being freely rotatable on that member about a second respective axis, said cultivating means being releaseably secured in a mount on said working member and said mount being connected to said working member through a first pivotal axis, said cultivating means being pivotable in said mount and turnable about a second pivotal axis, said cultivating means being adjustable about both pivotable axes and fixable in any one of a plurality of different working positions relative to either of said pivotal axes, said second pivotal axis extending substantially parallel to said upwardly extending axis and crossing said first pivotal axis, said first pivotal axis being located nearer to said upwardly extending axis than said second pivotal axis.
