What seed discs and what size are your soybeans? If you are using 130-cell seed discs with big soybeans, the big beans will knock each other off of the seed discs, causing lots of small vacuum leaks, causing your loss of vacuum. Lay a seed disc flat and line your soybeans up on the holes in the seed discs....if the beans are touching, there's your problem. Then go with a 100-cell disc.
