In addition, new Cat motor graders have increased production by 400 percent compared to what had been possible using the old equipment.
“With the new machines, we have constant production,” said Hall. “Our uptime has increased dramatically.”
Improved uptime enables crews to better maintain existing roads. “Our roads are better than they’ve ever been,” said David Burkhart, road foreman. “We’re continuously maintaining roads. That makes a big difference.”
The switch from steering wheels and levers in older machines to the joystick-operation of the M Series Motor Graders has made operation easier and improved production.
“It’s a whole lot easier on operators. They do a better job, and there’s greater productivity,” Hall said. “Operators love the joysticks and don’t want to go back to conventional motor graders."
Chris Keith, road superintendent, said, “The joy- sticks have increased productivity. Everything is so accessible. The operators aren’t pulling on levers all day long, and aren’t as worn out at the end of the day.”
“It’s just easier to work,” said Burkhart. “With the old machines, you had six levers and a steering wheel. Now, operators are doing the same work using two joysticks.”
Motor graders maintain unpaved roads and complete base course work for the construction of paved roads. The 140M2 AWD is also used for road construction. “When rolling eight inches of base course, our crews need a big machine,” said Keith.
￼The 140M2 AWD’s all-wheel drive is an advantage when operators are pulling ditches. “The machine also provides our operators with great stability while working in ditches,” Keith said.
Front-wheel drive is a great benefit when working on slopes. “They set the speed, and that holds them up on the slopes,” Burkhart said.
The machine also has the power to cut hard, packed gravel. “The 140M2 AWD cuts gravel that has set up. If you’ve ever cut gravel that’s set up, it’s like cutting concrete,” Burkhart said.
Leased machines are covered by warranty for the life of the three-year agreements. Dealer, Riggs Cat, provides warranty repairs. County employees take care of oil changes and other preventive maintenance.
“The warranty has improved uptime, and has been great for us financially,” Hall said.
County crews now have the necessary machines to improve the road system. “We do it all,” said Hall. “We have all the equipment necessary to build and maintain roads.”
