John Deere A135462: Improving Corn Singulation with the ExactEmerge™ Cell Corn Bowl
Precision at 10 MPH: Optimizing Your Planting with the New John Deere A135462 Seed Plate for Unique Shaped CornSeed
Every farmer knows that in the world of high-speed planting, singulation is everything. When you’re pushing 10 mph with a John Deere ExactEmerge™ planter, even the smallest inconsistency in seed size can lead to skips or doubles—and ultimately, lost yield.
That’s where the John Deere Order A135462 Cell Corn Bowl comes into play. If you've been struggling to maintain precision with small or medium flat corn, this specialized bowl might be the missing piece of your planting puzzle.
Why the A135462?
The standard corn bowl is a workhorse, but it isn't always the "one size fits all" solution for every seed variety. The A135462 is engineered specifically to handle the tricky geometry of small to medium flat corn (typically ranging from 2400 to 1400 seeds/lb).
Key Features include:
-
32 Specialized Cells: Features 4.5-mm (0.18-in.) cells designed to cradle smaller seeds more securely.
-
Wider Vacuum Range: This bowl allows for a broader range of vacuum settings, giving you more flexibility to dial in the perfect "hold" on your seed.
-
Enhanced Singulation: By better matching the cell size to the seed profile, it drastically reduces the "bounce" and mis-picks that lead to doubles.
Technical Comparison
While the A135462 is a specialized tool, it's designed to be a drop-in replacement for the standard A92777 corn bowl.
| Feature | Standard Bowl (A92777) | Cell Corn Bowl (A135462) |
| Best For | Large/Round Corn | Small/Medium Flat Corn |
| Cell Count | Standard | 32 Cells |
| Cell Size | Standard | 4.5 mm |
| Compatibility | ExactEmerge™ Meters | ExactEmerge™ Meters |
Pro Tip: When swapping to the A135462, don't forget that it requires a hub height and double eliminator adjustment. Proper tensioning and calibration are critical to ensure that 10 mph speed doesn't compromise your $99\%+$ singulation goals.
Is It Worth the Switch?
At a price point it is a relatively low-cost investment for high-value seed. If your seed guide shows a high percentage of small flats, making the switch to the A135462 can pay for itself in a single afternoon by eliminating the gaps in your rows.
Regularly inspecting your seed meters and ensuring your bowls aren't worn is the difference between a "good" stand and a "perfect" one. If you're heading into the field with small flats this season, make sure your planter is equipped to handle them.
Are you seeing more small flat seeds in your bags this year, or are you sticking with the standard large rounds?
