Cummins Tier 3 engines standard on new Champion Production Class Graders
Champion Motor Graders has specialized in the development of motor graders and attachments for over 25 years. Their line-up now includes seven basic models, with operating weights from 12,000 to 24,000 pounds, featuring the full range of single-axle, tandem and all-wheel 4x4 and 6x6 drive systems. According to Jeff McKee, Vice President Engineering at Champion Motor Graders, the major benefit of the larger six-cylinder engine on the C110 C Grader is the fact that the engine works at the bottom of its range and remains under-stressed. “What the two extra cylinders primarily offer is a smoother drive and better torque-curve at the lower RPMs,” says McKee. “The grader’s torque-drive doesn’t drop off like it would with a four-cylinder engine. What operators should notice is much less use of the engine’s inching pedal when they’re running the graders slowly or in fine grading applications.” McKee says that operators can achieve the same smooth control at low speeds and fine grading feel with the six-cylinder’s conventional direct-gear drive that they do with the hydrostatic drive on Champion’s Compact Graders equipped with a Cum-mins QSB4.3 Tier 3 engine. “Torque directly translates to the draw-bar pull,” says McKee. “The more torque you have, the more ability you have to move more dirt at lower ground speed. It really comes in handy in more delicate operations and also allows the machine to carry a heavier load without changing gears. It also gives the operator one less thing to worry about.” “Having the Cummins Tier 3 engine standard on our new Production Class Graders is really a win-win situation,” says Bryan Abernathy, Executive Vice President for Champion Motor Graders. “Our customers get to keep all the power they have become accustomed to in our compact graders, while at the same time enjoying increased engine life and lower noise, with the knowledge that they are helping the environment.”
Searching for the best-performing excavator? Your search ends here. We tested the Volvo EC350E and EC380E against a leading competitor in three different tests: trenching, truck loading and lifting capacity at reach. The results show a 20% difference in cost-per-ton, a 15% difference in tons-per-hour and a 12% difference in both operating costs and lifting capacity.
