Abstract:
An individual disc mounting system for an agricultural implement having a plurality of individual disc blades, the mounting system comprising:a. a leaf spring with an upper leg and a lower leg connected by a closed end, said lower leg having a longitudinal axis and a bottom surface generally parallel to said longitudinal axis;b. a mounting apparatus configured to attach said upper leg to the implement, such that said lower leg longitudinal axis is oriented generally horizontally; andc. a disc spindle apparatus attached to said leaf spring lower leg such that said disc spindle apparatus extends outward from said lower leg in a direction which is generally transverse to said lower leg bottom surface, said disc spindle apparatus supporting a bearing which accommodates only one of the individual disc blades such that the disc blade is positioned alongside a portion of said leaf spring lower leg and is freely rotatable relative to said spring lower leg, wherein positioning of said leaf spring at least partially alongside the disc blade allows the disc blade to deflect vertically, horizontally and/or torsionally when it encounters an obstacle.
