This is not a cell disk. It'ss a flat disk. And John Deere has been making it since 1991. The ProMAX 40 Flat is designed as a component of the entire John Deere VacuMeter™ system…that means you don't need to buy a new hopper just to make it work!
The design of the ProMAX 40 Flat, as well as the positioning of the disk within the meter, allow seed to be released from the optimum position above the seed tube. The new Flush-Face seed tube allows seed to drop uninterrupted through the tube, so every seed is properly released into the tube, and every seed clears the tube with even spacing.
The ProMAX 40 Flat doesn't have cupped cells to help carry the seed, but rather utilizes flat holes and a higher vacuum level to ensure every hole is populated with one or more seeds. A double eliminator then gently removes all but one seed at each hole for precise population control. Lastly, a knockout wheel makes certain that each hole is clear of any debris after the seed is released from the disk.
