Tapered bearings should be repacked annually & checked for wear. To check for wear, lift the planter off of the ground,
check for endplay in the bearings by moving the coulter blade in & out. Rotate the blade to check for roughness in the
bearings. If bearing sound rough, the hub should be removed & the bearings inspected & replaced if necessary.
