SEEDING CHART FOR THE JP1
Below is a chart detailing the gear ratios and rollers needed to plant the following crops with the JP1.
There are FOUR variables to adjust when operating the JP1: the rollers, the gears, the number of rows per 30-inch bed, and the hopper brush, which is the little brush inside of the hopper which controls the amount of seed flowing from the roller.
