Is planting accurately while running 10 mph possible? John Deere says yes, if you’re using its new seed delivery system ExactEmerge row unit. Unveiled at the 2014 National Farm Machinery Show in Louisville, Kentucky, the ExactEmerge promises precise seed placement and spacing— 10% better at traditional speeds — but boasts the ability to travel at much faster planting speeds without sacrificing accuracy.
According to John Deere, ExactEmerge features a new, rigid bowl-shaped meter and brush-style doubles eliminator that requires no adjustment. It is designed to provide a smooth, crisp seed handoff to the industry-exclusive brush belt which replaces the seed tube. ExactEmerge units handle all seed shapes and sizes achieving 99 percent singulation with no mechanical adjustments – even over terrain with slopes up to 15 degrees.
Bernard Tobin, Ontario field editor and the lone RealAgriculture staff member who made it Kentucky, was on hand at the launch of this field-ready unit to talk planter specifics with product manager Elena Kaverina. Kaverina explains how John Deere has changed the plating unit open the planting speed window and when farmers could being seeing these units in the field.

According to Kelby Krueger, product specialist, John Deere Seeding Group, the ExactEmerge row units are a perfect fit for producers who want to plant more acres in less time due to narrow planting windows, or to increase the size of their operations without adding equipment.
“Another important feature is that our new brush belt does not have to be synchronized with finite meter speeds. The systems are completely independent of each other, allowing the meter to turn at the right speed for the desired seed population, while the delivery system exactly matches ground speed,” explains Krueger. “This careful controlling of each seed from the meter to the trench and then releasing it at the correct rearward velocity allows the gentle placement of each seed in the trench without the normal bounce and roll that would otherwise happen at the higher speeds. We can do this with both corn and even with high- rate soybeans. And because we never let go of the seed until each one is in the trench we’ve drastically reduced the ill effects of rougher planting conditions.
This new design also eliminates the long gravity drop and retains the seeds in the brush providing high quality spacing when stopping the planter in the field. The combination of seeds retained in the brush and a new Fast Start feature eliminates skips in the field when growers start planting from a stop. There will no longer be a need to back up to start planting.
Two 56-volt electric motors per row unit rotate the meter and brush belt independently to achieve the desired seed population with speed matching delivery. The new electric motors are brushless, maintenance free and engineered to last the life of the average planter.
ExactEmerge row units are compatible with 1775NT and 1795 model planters with central commodity systems (CCS) in 15-in., 20-in., and 30-in row spacings for corn and soybeans. All planter control and monitoring is made easy with the enhanced SeedStar 3 HP system that provides fingertip control of different planting functions and access to all planting data. In addition, ExactEmerge customers have access to John Deere FarmSight services and data through MyJohnDeere.com.
