Abstract
A pick assembly for picking potatoes from a supply in a potato planter and moving them to a discharge position includes an arm that supports a plurality of picks that will engage the potatoes. The arm is mounted on a rotating wheel, and the picks are held in the arm with gently tapered bores in the arm and mating gently tapered conical surfaces on the pick that seat together when the pick is installed in the arm. The picks are maintained under axial compression loads to force the mating tapered surfaces together during use.
