Opposite. Have you ever ridden a ten speed? The small gear at the pedals and large gear at the wheel is what you use to climb hills. The small gear is the driving gear. One revolution of a small gear only moves a few inches of chain. One revolution of a large gear in this location would move much more chain driving the hopper to go faster. The gear on the hopper does the same thing only in reverse. If the hopper gear was the same size, the hopper shaft would turn at the same speed as the planter shaft. If the gear was smaller, the same amount of chain distance traveled would make more shaft revolutions. The way this is set up, the fertilizer hopper is being slowed down as much as possible- unless there is a larger gear available. for the hopper shaft. Somebody must have priced out a bag of fertilizer.
