Tier 4 Engines are Here — Are Your Customers Ready?

The new engines are coming! The new engines are coming!

Actually, the new Tier 4 engines are here, and they are under the hood of many of the machines being operated today.

The U.S. Environmental Protection Agency (EPA) has been working diligently to clean the air that comes out of every engine that powers our economy. The agency’s efforts require equipment owners, operators, technicians, dealerships and manufacturers to be aware of, educated about and dedicated to keeping engines and machines serviced and clean.

Sounds easy enough, right? But having a proper maintenance program, understanding the value of equipment, and working with operators and dealers to ensure it is in top shape isn’t enough anymore. We’re not talking about Grandpa’s tractor we could keep running with a pair of pliers and a crescent wrench.

The requirements the EPA has placed on the manufacturing industry have required that Tier 4 engines and the vast majority of equipment be more technologically advanced and driven by computers and software code. In addition, the machines and attachments of today are working – or, more specifically – communicating together to ensure they are as productive as possible.

In response to these developments, an AEM committee of member experts have developed a campaign to heighten the awareness of the new and mandatory demands placed on the owner, the operator, the technician, the dealers, the distributors and the equipment’s manufacturers to maximize uptime and ensure performance expectations are met.

The CLEAN campaign serves to deliver the basic facts regarding the new technology under the hood of every machine with a Tier 4 engine. As a manufacturer, AEM encourages you to spread the message of CLEAN by sharing best practices about how to get the most out of the machinery your business counts on to be up and running every day.

So investigate the CLEAN message. But more importantly, leverage its resources to expand your knowledge and your ability to train others, as well as to gain access to tools to better serve your equipment, so your equipment will better serve you.
