Edward Gamaliel explains the John Deere Duradrum, a forage harvester component built for durability and efficiency. The Duradrum's design reduces wear on cutting parts and lowers operating costs during harvest.
Did you know that the John Deere Duradrum is the original multi knife design of our forage harvesters? And that it delivers far more than just premium chop quality? Our unique duradrum design has been engineered for durability and precise cuts for over 30 years. Our drum also offers maximum flexibility to easily achieve required chop wings. So we can run with a full half or even three quarter set of knives and a When foreign objects reach the knives of the drum, the knives are automatically pushed backwards thanks to elongated holes. This prevents major damage to the drum itself and saves in replacement costs. Now, at first glance, there are a high number of knives and bolts, but the advantages are clear. Yes, it does take a little longer to replace an entire set of knives, once or maybe twice a year. However, this design offers the quickest solution for getting the machine up and running again during harvesting. And that's when it really matters. In the middle of the day, when you don't want the entire chopping chain to stop. Because what if you need to replace a knife while the trailers are waiting? Well, no problem. Fit a new knife, adjust it to the shear bar, grind it briefly and off you go. It's not necessary to grind new blades to the same level as the others. Each individual knife can be worn down to its wear limit, so running costs also play a decisive role in the development here. Trust John Deere to deliver innovative solutions for every harvest, focusing on efficiency, operating costs and ease of use.
