Sidedress Simpler with AutoTrac Vision for your John Deere Tractor

AutoTrac Vision Guidance for Tractors

by Jared Wheeler, Assumption, IL

AutoTrac Vision for tractors is a great new product for customers that sidedress and/or row crop cultivate.  John Deere previously released this for sprayers,  but it is now available for 7 and 8 family tractors, 30 series and newer.  The system works in row spacings from 20 up to 40-inch row crops in the early stages between 6 inches tall and 90% canopy.  The camera detects the color difference between the crop and soil and guides the tractor between the rows.

This new technology is ideal for customers that are in fields where they don’t have the original planting guidance lines.  It also works great for customers experiencing GPS drift or customers whose implement width doesn’t match the planter width.  We demoed this unit to a customer who planted with a 24 row planter using RTK signal and then came back and sidedressed with a 15 knife bar.  Even though the customer planted with RTK, the planter would sometimes pull to one side.  Also, the “guess” rows were occasionally off a couple inches and he would have to side shift his guidance line in the sidedress tractor to make up for it.  These additional steps are eliminated with the AutoTrac Vision system because the tractor is now automatically side-shifting for you by using the crop row as the reference point for guidance.

I think this product would be especially beneficial for ag retailers that are custom applying because they usually don’t have the customers planting guidance lines to go off of when they are applying fertilizer.    The camera will guide them through the field with ease.  Contact us today for more info or to schedule a demo.

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.

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.
