Motor graders have traditionally been the domain of only the most experienced equipment operators. The complexity of the controls and the finesse required to maintain precise grades have often necessitated an extensive learning curve — in some cases, years of regular use.

Most manufacturers are striving to reduce this learning curve via increased automation of machine functions. This automation can be largely attributed to advances in electronics — a byproduct of emissions control technology.

"Every engine manufacturer had to figure out a way to make their engines burn cleaner, yet still be very productive, capable engines," notes Howard Woolard, motor grader commercial manager, Caterpillar Motor Grader Product Group. "It stirred the creativity that led to electronic engine controls."

Electronic engine controls were initially introduced with Tier II designs. They not only delivered emissions compliance, they provided improved overall power management. "It allowed us to electronically control the engines and change the characteristics of how the engines performed based on what the customer was trying to do with the machine," says Woolard.

The electronics have since been married to other machine systems, serving as the "building blocks" for greater automation of key motor grader functions.
