Hitching to the rake. Rake is designed to work with pole thirty-one inches or shafts forty-two inches from the ground, measuring underneath at front end. Only at this height are best results obtained. Oftentimes a rake does not do satisfactory work because the neckyoke holds the pole too high or too low, usually too low. If pole or shafts sag in the middle, remove, turn pole over and rebolt to rake. Keep pole bolts tight.
