  • Eccentricity and wobble sensing device
    Patent number: 6871416
    Abstract: A wobble and eccentricity sensing device is provided for use with a planter blade. The device includes a stand having a shaft adapted to mount the planter blade thereon for rotational movement of the planter blade about the shaft. A wobble indicator is coupled to the stand to measure the concavity of the planter blade as the planter blade rotates at least one revolution about the shaft. The wobble indicator is adapted to contact a face of the planter blade. An eccentricity indicator is also coupled to the stand and is adapted to contact an outer edge of the planter blade to measure the eccentricity of the planter blade as the planter blade rotates at least one revolution about the shaft.
