Have You Seen the New John Deere 1775NT ExactEmerge™ High Speed Planter Yet?

A few growers have started planting with their new John Deere Exact Emerge™ Planters this spring.  John Deere and Precision Planting have introduced technology that will allow you to plant twice as fast.  Fast planting is possible due to the John Deere BrushBelt Trench-Delivery System or Precision Planting's speedTube, a flighted belt, which replaces the traditional seed tube.  Both ensure accurate seed spacing and depth at higher speeds.  For more information, check out the video below.





  High Speed Planting Tips:
  • Some have said that they have not been able to reach speeds of 10mph with their John Deere planters.  One problem may be that planting speed is dependent on field operations and ground conditions (field size, shape, or soil conditions).  More tillage tools may be needed to open up fields to keep up with the high-speed planter that will cover more acres.  When making your final tillage pass, make sure that the field is as smooth as possible.  You may want to add another headland pass for more room to turn around as well as plant in the same direction as your spring tillage operation . High-speed planting can also be performed on strip till and no till without issues. Think more in the terms that you can plant 2 times the speed that you currently plant with a normal planter.  
  • Most tractor planter combinations can handle speeds of 7 to 7.5 mph, but 10 mph may require a bigger tractor.  John Deere recommends 40% more power if increase speeds from 5 to 7.5 mph and if increasing speeds from 5 to 10 mph, you will need 80% more power if you're current max planting speed is 5mph. Lastly, remember to consider the terrain of your field.  Each degree of slope may require 5% more horsepower.
  • Does your planting technology need updated?  John Deere recommends MyJohnDeere and Seedstar mobile, while Precision Planting has 20/20 SeedSense and Fieldview for high-speed planting. Information such as singulation, spacing, downforce, ride quality becomes critical when you are planting at twice your normal planting speed.  It is also suggested that you do a meter runoff before planting to help you learn where your monitor seeding need to be for higher speeds.  Keep in mind, that it has been said that the more you use your planter, the better it may work, so basically, it may need "broke in".
  • Down pressure is especially important at any ground speed, but at higher speeds, a responsive system helps to maintain required ground contact and depth control to maintain uniform emergence.  All ExactEmerge™ planters come equipped with active pneumatic downforce.  In addition, Precison Planting offers AirForce (active pneumatic downforce) and DeltaForce (active hydraulic downforce).  If you buy Precision Seed's  SpeedTube, you must buy DeltaForce.  Precision Planting recommends DeltaForce for high speed planting to insure that row-by-row and instantaneous hydraulic response is the right match at higher speeds.  
  • The planter attachments (closing wheels and row cleaners) do the same jobs at higher speeds, but faster, which may change the way they operate.  It has been suggested that you may have to run more closing force because the closing wheel is covering more distance per second.  Cast wheels with more weight may be needed if your soil conditions can support the minimum closing force settings each year.  Precision planting says that they have discovered that the pinch style closing systems deliver the best performance at higher speeds.  They also say to watch out for aggressive closing systems as they might throw the seed.  Evaluate your row cleaners to make sure that they are removing the right amount of residue.
  • Be ready for increased seed handling with high-speed planting, you may need more seed tenders.  When running more seeds per second through each row unit, there will be more wear on parts and seed treatments.  John Deere and Precision Planting recommend using a 80:20 talc graphite mix.  Burrus has heard that Bayer Fluency Powder, also a lubricant agent, has worked too.  Of course, the vac pressure will depend on seed size and may need to be decreased, even lower than what has been recommended.  The seed disk cover may need to be moved closer to the hub as close as it can go, so that you can barely move it by hand.  Fertilizer application (pump capabilities and orifice size) may need to be adjusted so that they can put out the right amount of fertilizer at increased speeds. Lastly, be ready for more high speed planter maintenance as increased speeds may increase equipment wear and tear.
