The combine that Claas brought to field demonstrations for the Farm Progress Virtual Experience is touted as the most powerful Lexion combine yet. The conditions at the Farm Progress Show site in Boone, Iowa, where the demos were filmed, gave the machine a workout, but it appeared to pass the test with flying colors.
Corn at the site, while not hit as hard by the early August derecho as corn in many other places in Iowa and other states, was still twisted and partially lodged. With a modern corn head and automatic adjusting features inside the machine, the Claas Lexion 8700 moved through the crop steadily, leaving very little corn behind.
You have two opportunities to get a better feel for what this combine can do using virtual technology. First, you can watch it run during field demonstrations. Visit FPVExp.comand find the link to a pass by the Claas Lexion 8700. If it’s your first visit to the FPVX website, you will need to register, but it’s quick, easy and free. Max Armstrong narrates the virtual demo, pointing out features of the new Claas Lexion 8700 along the way.

Or, you can check out the slideshow accompanying this story. The author rode along with Greg Frenzel, a product specialist with Claas, as the combine worked the same field in Boone the next day. Frenzel also did a walkaround of the machine to provide a closer look at various features.
Spokespeople say all models in the new Claas Lexion 8000-7000 Series are more powerful than the models they replaced. Using the APS Synflow Hybrid System, which is an upgrade to the APS Hybrid System, these combines have 10% more harvesting capacity than previous models. APS stands for Accelerated Pre-Separation.
At the same time, says Jeff Gray, product manager of field support for Claas of America, these models handle grain gently and put quality grain into the semitrailer headed for your bins or the elevator.
In fact, Claas asked an independent firm to compare grain quality from a new Lexion combine versus two competitive Class 8 combines. Samples from two soybean varieties were analyzed at the Illinois Crop Improvement Association lab. Samples from the Lexion combine matched or excelled samples from competitors in various categories, Gray reports.
Automation features available on the Claas Lexion 8700 allow it to produce quality grain with minimal grain loss while still harvesting at a high-capacity level. The 8700 that shelled corn at Boone was equipped with the Cemos automatic operating system. Frenzel notes that it automates combine adjustments, making them on the go as needed, using existing machine components and sensors.
Data from Claas indicates this results in 10% more capacity, 32% less foreign material in a grain sample and a 58% increase in grain retention versus operating the same machine without Cemos automation.

<p>BIG MACHINE AT WORK: Greg Frenzel guides the Claas Lexion 8700 combine through partially lodged corn at the Farm Progress Show site near Boone, Iowa. Storm-damaged corn didn’t prove to be a big challenge for this machine.</p>

<p>WIDE THROAT: Note the width from the corn head to the threshing portion of the machine. Frenzel says that sets the stage to handle lots of capacity efficiently from the start.</p>

<p>DRIVING THRESHING: Threshing occurs in the front part of the machine, Frenzel says. The Claas Lexion combine features a 30-inch threshing drum and two rotors, and uses Lexion’s APS Synflow Hybrid System to process the crop.</p>

<p>100% SEPARATION: The middle half of the machine is devoted to separation functions. Frenzel says the combine can achieve 100% separation of grain from other material, allowing it to produce clean grain samples while still handling a large amount of material at one time.</p>

<p>SPREADS EVENLY: Here’s a view of the rear of the combine, showing how this 8700 model is equipped to spread residue. The goal is to spread it across the width of the header.</p>

<p>WIND CHANGES: Note the white flap in the center of the photo. It helps detect changes in wind direction. The combine can be equipped to adjust how residue is spread to compensate for changes in the wind during the day.</p>

<p>POWER SOURCE: The Claas Lexion 8700 comes with a Mercedes-Benz engine, which delivers plenty of power for the machine and all necessary functions. The sliding ladder at the rear provides access to the engine and other key parts located near the top and rear of the combine.</p>

<p>GRAIN TANK: The grain hopper on the Claas Lexion 8700 combine is rated at 510 bushels. It can unload at a rate of 5.1 bushels per second. Both these features help increase efficiency and total number of acres that can be harvested per day.</p>

<p>TRACKS CLOSE-UP: You can order the Claas Lexion 8700 with tracks. The Terra Trac design shown here on the model at Boone, Iowa, provides a smooth ride in the field and on the road. Both track and wheel models can travel up to 25 miles per hour on the road.</p>

<p>COMPENSATING FOR SIDEHILLS: Slope compensation that allows for even, efficient threshing and harvesting even on slopes up to 20% has long been a feature of Lexion combines. This continues with the 3D compensation system plus 4D rotor slope compensation on the 8000-7000 Series. Sensors making that possible are located near the rear of the machine.</p>
