Common Wear Parts on a John Deere ExactEmerge High Speed Planter

by Lucas Veale, Assumption, IL 

John Deere’s ExactEmerge Planter has completed another successful spring planting season.  The productivity, seed placement, and uptime of these planters are impressive when compared to even the most stringent of standards.  This is the 4th season for ExactEmerge Planters and John Deere has continuously improved this product.  In this post, we will review some of these improvements and after four years we have a good feeling for the wear life of the planter components.

First, we will look at the new meter housing wear pad pictured below.  Starting in 2018, this wear pad is made out of a new ceramic material.  In previous years it was made out of the same metal material as the housing.  Prior to the change, this proved to be an annual replacement item.  If not replaced annually, the bowl would begin to wear into the housing during the second planting season.  The new ceramic wear pad pictured below is from a 16-row planter that planted over 3200 acres this spring.  As you can see, there is very little wear and the wear dimple is still clearly visible.  These ceramic wear pads retrofit back to previous model year ExactEmerge Planters.  This is a nice improvement by Deere and was factory installed starting in 2018.

The next item we will cover is the lower pulley assembly.  In 2017, John Deere changed the design of this assembly and assembly cover.  In the picture below, the bottom pulley is the older style and the top one is the newer style and it is shown installed in the brush housing.  Notice the front or lower portion of the older style.  It has a plastic lip that the newer one does not as shown by the arrow.  John Deere removed this lip since crop material could build up between the brush and the housing wall, causing the brush to stall and even causing undue wear on the brush.  This was noticed mostly in soybeans.  The new assembly is opened up to allow excess debris collected by the brush to discharge automatically.  This new style is retrofittable to older model ExactEmerge Planters, but you will also need to replace the lower cover as well.

The top picture is the new style assembly

A common wear issue with the lower pulley assembly is the outer lip of the lower idler.  We have seen some of the lower idlers with the outer lip worn completely off.  This will cause the belt to come off track and potentially damage the brush belt.

The wear in the top picture has happened after several thousand acres, but should be a part of your postseason or pre-season inspection to make sure you don’t have a thin outer lip on the lower idler.  The new lower pulley assembly does not have any changes to address this issue.  Again, this doesn’t start to show until after many, many acres.  One of the symptoms you may encounter with this issue is a row starting to plant low, especially in soybeans.  Upon inspection of the brush (see pic below) you will notice that the brush is shifted to the edge of the idler and the worn outer lip has cut into the brush and reduced its width.  This will prevent a crisp and efficient handoff of the seed from the meter to the brush and some seeds will “free fall” in the brush module.

The reduced width of brush belt

One of the most common questions is, “How long do the brushes last?”  Of course, this depends on the environment they have worked in as well as the care they have received.  We are seeing an average brush lifespan of 12,000 acres on a 24 row planter.  We have seen some last significantly longer and some significantly less.  Again, the care received and the exposed environment will have a large impact on the brush life, but 12,000 acres can be used as a normal wear guide.  The symptom of a worn brush is low population on that row, again which is especially noticeable in beans.

The last thing to pay attention to is the sensor installation which should be properly inserted into the sensor slot.   We have seen when these sensors are incorrectly installed they can cause a false “double” and false high population.  It will also significantly impact seed spacing.  Notice in the first pic that there is a tab on the stainless steel wear strip.  If this tab is outside of the sensor slot, the seed will hit the tab and move back in front of the sensor eye causing the false double and false high population.  The lower picture show the correct sensor installation.

Hopefully, you have picked up some tips as you inspect your ExactEmerge Planter before putting it in the shed for next year.  Always remember to remove the seed disks from the seed meter and remove the brush from the brush module for winter storage.  Also, don’t forget to check out our planter videos on www.sloans.com for more information.

John Deere ExactEmerge: Buy New or Retrofit?

John Deere’s Exactemerge high-speed planter has definitely changed the game.  With improved seed spacing over conventional planters even at speeds of 10+ mph, unmatched productivity and accuracy now go hand in hand.  Covering dramatically more acres per day and still doing a better job in an ever decreasing planting window is a value story that hasn’t been seen since the introduction of the STS combine in 2000.  Sloan Implement has ExactEmerge customers that have cut their planting fleet in half and still get more done in a day, all while improving the plant stand.   This frees up manpower to do other tasks at a time when skilled farm labor is ever more difficult to locate.

John Deere offers two different options for customers who want to bring this technology to their operation: Buying a new or used Exactemerge planter or Retrofitting an existing 2011 or newer conventional John Deere bulk fll planter.  So what is the best option?  Both offer pro’s and con’s so let’s walk through both scenarios:

Buying a new Exactemerge planter: 

John Deere has introduced features each year since the Exactemerge’s introduction that cannot be retrofitted back to previous model planters.  Frame weight distribution is only available as a factory option and cannot be retrofitted to previous models.  Folding the planter through the display, thus eliminating the fold box, is also a factory only option.  Seedstar 4HP is new for the 2018 planter line-up and is not available for retrofit at this time.  Seedstar 4HP requires a Gen IV display.  The larger screen offers greater flexibility with the planter run page setup for viewing more functions on the screen at the same time.   The frame has also received a few tweaks, in particular, the markers can better handle the increased loads of 10+ mph planting speeds.  Buying new insures that you will have the latest technology as well as a full machine warranty for the planting season.

Retrofit a 2011 or newer central-fill planter to the Exactemerge planting system:

This option allows customers to get the Exactemerge technology at a substantially reduced cost vs. buying new.  Customers can get most of the latest technology except for the items listed above.  The Exactemerge row unit, pneumatically adjustable row cleaners, individual row hydraulic down force, and pneumatic closing wheels can all be installed on an existing planter to get these technologies for less money.  The basic Exactemerge retrofit unit comes with a new shank, openers, scrapers, gauge wheel arms, meter, brush module, parallel arm bushings, and an electrical system that includes vacuum automation and curve compensation.  All of the new components have a full planting season warranty.  What’s more, you can still use your existing 2630 display to operate the retrofitted planter, saving the cost of upgrading to the new Gen IV display.  The frame and seed delivery system both remain the same.  We have done several retrofits and customers have had great success while saving money.

Sloan employees prepared 7 short videos discussing ExactEmerge retrofit kits that can be viewed here:

As you can see, both options have a value story that is different.  What is not different is the performance and productivity each option will bring to your operation.

Is this the most high-tech corn planter?

by Toby Taylor, Lanark, IL 

This John Deere 1770 24-30 was purchased new in 2014 from the Lanark, IL location of Sloan Implement.    The owner then built the liquid fertilizer system from the ground up.  There are 4 hydraulically driven fertilizer pumps that are all electronically controlled.   You can adjust the fertilizer independently for each row on a controller that the owner made custom for the planter.   He can also monitor the flow to each row.  The planter can apply 60 gallons of fertilizer per acre and there is a 2500 gal tank pulled behind the planter.

New installs on the planter for 2017 are Dawn hydraulic downforce fertilizer openers, Dawn air adjust frame mounted row cleaners,  Ag Leader hydraulic downforce, spoke gauge wheels,  JD ExactEmerge high-speed retro-fit kit, and Dawn spike closing wheels.  He will be pulling this planter with a 9560RT track tractor.

Here are some pictures of the planter in the Lanark service department as they make these updates.
