With a team of in-house developers, we’re constantly evolving FLEX Controls to be fully customizable to your fleet, your drivers and your needs. FLEX Controls isn’t just the only factory-direct software system for mixers, it’s the only control system worthy to be in a McNeilus.

From Auto Load at the plant to System Washout after the delivery, FLEX Controls gives you the tools you need to make it easier than ever to get the job of loading, mixing, hauling and delivering done right. Simply put, we’ll handle the concrete, you handle the road.

We are truly honored that the industry continues to recognize our FLEX Controls system and all the hard work our team puts in every day to continue to innovate this product with the customer in mind.

“FLEX Controls for concrete mixer trucks is continuously evolving, always keeping customers at the forefront and giving them the chance to have a say in the next generation of features and functionality,” said Bryan Datema, Sr. Director of Engineering, Innovation, and Product Performance. “It’s very rewarding to see our innovative system continuing to top our industry nearly six years after its introduction.”


“In an effort to improve on safety, we made a change to our ready mix truck design and removed the ladder and added a washout system tied to our FLEX Controls. It eliminates the need for drivers to use the ladder to clean out after each load. This removes potential safety hazards like the pinch point created by folding the ladder, fall prevention from ladder or crows nest, and sprains, strains, slips and falls from ladder misuse.”
