Combine Threshing and Equipment Maintenance Tips

Apr 03, 2018

The threshing elements and concaves are some of the hardest working elements in your combine. That being said, it’s essential to perform routine maintenance on these parts and measure wear when possible to keep everything running smoothly. Doing so can ensure that the harvesting season is as fruitful and successful as you need it to be.

Let’s take a look at some tips for measuring wear on your combine threshing and separating parts.

Check the threshing element with the combine clearance gauge from John Deere. If the tool goes over the trailing edge, the element needs to be replaced.
Check the separator tines by placing the edge of the gauge against the rotor to measure the length of each tine.
Use the corn or grain end, depending on your concave type, to measure wear.
When replacing your elements or tine, replace them in quantities of three to keep the rotor balanced.
John Deere offers small wire concaves for items, such as wheat and barley. Round bar concaves are ideal for corn and soybeans. Large wire concaves are recommended for rice, sorghum, and confection sunflowers. However, you can install concave inserts for wheat if you want to avoid changing out the concaves.
If you’re replacing parts in an earlier model machine, your John Deere dealer may offer aftermarket alternatives for you to use instead.
Schedule an offseason inspection with a John Deere dealer to spot any underlying issues before harvesting season begins. This will ensure that your machinery is in working order.

Video: Heat Stress in Pigs: What to Prepare for Before Next Summer - Dr. Joshua Selsby

In this episode of The Swine it Podcast Show Canada, Dr. Joshua Selsby from Iowa State University explains how heat stress affects swine biology and why now is the ideal time to prepare for next summer’s challenges. He breaks down its effects on muscle function, immune responses, and long-term metabolic outcomes. Learn how early planning can protect herd performance when temperatures rise again. Listen now on all major platforms! "Heat stress leads to a cascade of biological damage, beginning with metabolic disruption and expanding across multiple organ systems." Meet the guest: Dr. Joshua Selsby is a Professor in the Department of Animal Science at Iowa State University. With over 15 years of research on skeletal muscle physiology and heat stress, he focuses on understanding how thermal stress disrupts swine metabolism, immune function, and muscle integrity.
