Angle adjustment device for disc-type coulters

Abstract

The present invention involves a seed firmer with a pusher attachment that extends the life of the seed firmer and brackets for mounting the same to a planter. The disclosed invention additionally involves an adjustment mechanism for seed or grain drill planters which allows for the adjustment of the camber and/or toe of individual coulters on the planter.

What is claimed is: 
     
         1 . A planting mechanism for use with seed drill planter, comprising:
 a tool bar, mountable to a seed drill planter;   two disc-type coulters operationally mounted to the tool bar; and   means for adjustably positioning the disc-type coulters relative to the tool bar, wherein the positioning of the disc-type coulters relative to the tool bar is lockable once the desired positioning is achieved.   
     
     
         2 . The planting mechanism of  claim 1 , wherein the tool bar further includes a mounting point for attaching additional implements to the tool bar. 
     
     
         3 . A planting mechanism for use with seed drill planter, comprising:
 a tool bar, mountable to a seed drill planter;   at least one disc-type coulter operationally mounted to the tool bar; and   means for adjustably positioning of the at least one disc-type coulter relative to the tool bar, wherein the positioning of the at least one disc-type coulter relative to the tool bar is lockable once the desired positioning is achieved.   
     
     
         4 . The planting mechanism of  claim 3 , further comprising a pivotable spindle operationally connecting the at least one disc-type coulter to the tool bar. 
     
     
         5 . The planting mechanism of  claim 4 , further comprising a locking pin movable between a locked and an unlocked position;
 wherein the spindle may pivot when the locking pin is in the unlocked position; and   wherein the spindle may not pivot when the locking pin is in the locked position.   
     
     
         6 . The planting mechanism of  claim 5 , wherein the spindle further includes at least one indent sized and configured to receive the locking pin in the locked position. 
     
     
         7 . A planting mechanism for attachment to a tool bar of a planter comprising:
 a closing wheel having means for attaching to a tool bar; and   at least one disc-type coulter having means for adjustably positioning of the at least one disc-type coulter relative to the tool bar, wherein the positioning of the at least one disc-type coulter relative to the tool bar is lockable once the desired positioning is achieved.   
     
     
         8 . The planting mechanism of  claim 7 , further comprising a pivotable spindle operationally connecting the at least one disc-type coulter to the tool bar. 
     
     
         9 . The planting mechanism of  claim 8 , further comprising a locking pin movable between a locked and an unlocked position;
 wherein the spindle may pivot when the locking pin is in the unlocked position; and   wherein the spindle may not pivot when the locking pin is in the locked position.   
     
     
         10 . The planting mechanism of  claim 9 , wherein the spindle further includes at least one indent sized and configured to receive the locking pin in the locked position.
