Yates A-63 4-Sided planer 16-Knives on top and bottom 12-Knives on side heads Total rebuild Spare Chrome bed Spare side heads This unit was rebuilt a few months before it was removed from service. It was producing approximately 100,000 board feet per 8 hour shift when the mill was shut down. They produced 1 x 6 lumber. During transportation, one arm that adjusts the heads up and down was slightly damaged but does not effect overall productivity and will only cost a couple hundred dollars to fix.
