"By using a lower rpm and selecting a higher transmission gear, the high torque characteristics of the Volvo engine is fully utilized," Lowe explains. "You have the power you need to get the job done, but the economy of the slower engine speed when the power is not needed — all performed automatically and without operator input or sacrificing productivity.

Cost vs. benefits
Advances in electronics have succeeded in making motor graders simpler to operate, while optimizing overall performance. However, this added sophistication does affect pricing.
"Obviously, as any motor grader manufacturer makes advancements in technology, that does come at a cost," says Porter. He emphasizes, however, that designing other areas of the machine more efficiently can help offset many additional feature costs.
Samera agrees, adding, "Better controls and advancements have impacted the cost of machines [overall]. Contractors often have a difficult time justifying such increases in investments. However, productivity gains play an important factor."
When considering today's more advanced motor grader designs, you need to weigh the higher price tag against the potential productivity gains, as well as any costs savings you may achieve due to improved control of key operating systems. Crunching the numbers will help you determine if a premium product can ultimately generate a premium return on your initial investment.
