FurrowForce works fundamentally differently than other closing systems.
The first stage spike wheels are closest together at the bottom, working to truly close the seed furrow from the bottom up eliminating air pockets. The second stage stitch wheels carry the air bag force, to firm the soil over the seed to retain moisture.
FurrowForce on its own is a powerful product, but you also have the option to add load cells to measure and set weight on the closing system from the 20|20 monitor. When a load cell measures more or less weight than has been set on the 20|20, the FurrowForce system will automatically adjust row-by-row the force applied to the unit. When the second stage stitch wheels are carrying the correct weight, you know the first stage notched wheels are cutting into the soil at your chosen depth.
