Compared with conventional planters, John Deere’s ExactEmerge is expected to set new standards for planting speeds with advertised ideal performance at 10 mph. All model year 2015 planters will feature the new MaxEmerge 5 row unit.
Updated row units provide the foundation for John Deere’s high-speed planter that performs at 10 mph
It’s going to cause a double take in farm country when farmers double their planter speed. For model year 2015, John Deere introduces its high-performance ExactEmerge planter, which breaks conventional speed limitations—advertising speeds of 10 mph for ideal performance.
Before the speed of the machine could be made known, the company developed a new family of row units.
"Our goals were high-quality planter performance, which equals seed placement plus even emergence," says Elena Kaverina, product manager. "For the MaxEmerge 5 row unit, we merged
the best of the MaxEmerge XP and Pro-Series. The row unit could be called the heart of any planter."
The MaxEmerge 5 will be a common design across all John Deere planters for 2015 in mini, 1.6 bu., 3 bu. and 2 bu. twin-row hopper options. The meter is accessible for clean-out without removing the seed box, and switching crops is easier without tools. A common double eliminator with an adjustment knob shows settings for various crops.
John Deere engineers reduced elbows and improved the vacuum source to create more uptime and maintain population on extreme sidehills.
Built for speed. The new row unit is the platform for the ExactEmerge.
"We addressed the top five customer needs—maintain uniform depth, accurate seed spacing, accurate seed population, easy-to-use monitoring system and no machine downtime," says
Kelby Krueger, product manager. "We’ve been doing extensive testing for quite a few years—the past three years were in fields with growers across the Corn Belt."
He shares the story of how he planted a field for a farmer test cooperator in strips at 5, 7.5, 10 and 13 mph. In side-by-side rows that were planted at 5 mph and 13 mph, the farmer saw no difference. There was no striping across the passes at different speeds. At harvest, yield was the same.
Turning traditional planter setups on their head, the ExactEmerge features a rear-facing bowl-shaped meter and brush belt trench-delivery system that releases the seed only 2" from the trench bottom.
"Before, the seed tube was a limiting factor in speed," Krueger says. "The brush belt controls the seed from the meter to the trench. There’s no bounce or roll—just a true dead drop. It actually shoots the seed at a rearward trajectory, matching the speed of the tractor. The seed’s relative ground speed is zero."
