English: Spindle-type cotton picker seen from above. The 15 rows of yellow spindles are mounted on a pale blue cylinder. The direction of the spindles are controlled by a cam-mechanism where the ends of blue arms follow a pink track. The doffer cylinder is violet, with blue pads. The moisturizer is red. Brown is the ribs through which the spindles protrude into the pale green laterally compressed cotton plants that move to the left (due to that the vehicle is moving to the right)
