Method and apparatus for improving the efficiency of a John Deere vacuum planter

摘要

The efficiency of a John Deere planter to plant corn seed is improved where the planter is of the type having a vacuum operated metering unit enclosing a seed disk and a double eliminator. To improve the efficiency a kit is provided including an improved seed disk, an improved double eliminator, and an alignment tool for properly aligning the double eliminator with respect to the seed disk. When the parts are installed and properly aligned the planter can accept corn seed in the range of 1200 seeds per pound to 2800 seeds per pound without requiring readjustment of the vacuum setting or replacing the seed disk.
