Abstract
Abstract A planter apparatus for attachment to a tractor or other draft vehicle and having a pair of vertically disposed interconnected pivoting frames. Front and rear ground engaging wheels are mounted along the longitudinal axis of the lower frame, and a pair of transversely disposed discs are mounted therebetween along the axis and for forming an incision in the ground. A chain and belt drive from the front wheel actuates a rotating seed discharge mechanism in a housing mounted over the rear portion of the discs whereby seed is discharged into the incision. The rear wheel compacts the soil over the incision with the seed therein.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
119 words
A planter apparatus comprising; a tool bar adapted to be attached to the A-frame of a conventional tractor; a U-frame pivotally connected at one end to said tool bar; an H-frame rockably secured substantially centrally intermediate its ends to said U-frame, whereby said H-frame is rockable relative to said U-frame; a pair of ground engaging wheels rotatably mounted to the front and rear of said H-frame drive means on said H-frame; a pair of discs rotatably mounted on said H-frames intermediate said wheels and mounted thereon for making an incision in the ground; and means mounted on said H-frame and operatively connected to said drive means operative during movement of said tool bar for discharging seed into said incision.
Claim 2
Dependent Claim
119 words
A planter apparatus comprising; a tool bar adapted to be attached to the A-frame of a conventional tractor; a U-frame pivotally connected at one end to said tool bar; an H-frame rockably secured substantially centrally intermediate its ends to said U-frame, whereby said H-frame is rockable relative to said U-frame; a pair of ground engaging wheels rotatably mounted to the front and rear of said H-frame drive means on said H-frame; a pair of discs rotatably mounted on said H-frames intermediate said wheels and mounted thereon for making an incision in the ground; and means mounted on said H-frame and operatively connected to said drive means operative during movement of said tool bar for discharging seed into said incision.
Claim 3
Dependent Claim
119 words
A planter apparatus comprising; a tool bar adapted to be attached to the A-frame of a conventional tractor; a U-frame pivotally connected at one end to said tool bar; an H-frame rockably secured substantially centrally intermediate its ends to said U-frame, whereby said H-frame is rockable relative to said U-frame; a pair of ground engaging wheels rotatably mounted to the front and rear of said H-frame drive means on said H-frame; a pair of discs rotatably mounted on said H-frames intermediate said wheels and mounted thereon for making an incision in the ground; and means mounted on said H-frame and operatively connected to said drive means operative during movement of said tool bar for discharging seed into said incision.
Claim 4
Dependent Claim
119 words
A planter apparatus comprising; a tool bar adapted to be attached to the A-frame of a conventional tractor; a U-frame pivotally connected at one end to said tool bar; an H-frame rockably secured substantially centrally intermediate its ends to said U-frame, whereby said H-frame is rockable relative to said U-frame; a pair of ground engaging wheels rotatably mounted to the front and rear of said H-frame drive means on said H-frame; a pair of discs rotatably mounted on said H-frames intermediate said wheels and mounted thereon for making an incision in the ground; and means mounted on said H-frame and operatively connected to said drive means operative during movement of said tool bar for discharging seed into said incision.
Claim 5
Dependent Claim
