That’s where Empire Cat helps. The dealership provides training, including the use of simulators, to help operators meet the challenges of working on a variety of machines and road surfaces.
Empire Cat helped train operators who learned their trade using the steering wheel and shifters of traditional motor graders to make the transition to the joystick-controlled M Series. “They brought a simulator in before we even purchased the equip- ment,” said Pearson. “Trainers were here when the machines arrived.”
Pearson’s background as a motor grader operator has helped hone his knowledge of machines, and the features necessary to successfully complete county work.
When the county needed a motor grader primar- ily for snowplowing and other heavy-duty work, he knew the 140M2 AWD was the machine for the job. “The M2 has outstanding power,” Pearson said.
The M2 is one of two motor graders that the county uses primarily for special projects such as snow removal and rebuilding washed out roads. “We have a lot of monsoons. We may fix a road, then a monsoon hits, and everything is all blown out again,” Pearson said.
The three 140M Motor Graders primarily perform road maintenance.
In years past, the county had kept motor graders as long as 20 years, but Life Cycle Costing that Pearson has been using since 2007 has shown that maintenance costs for older machines are prohibitive.
Today, motor graders are kept on a seven-year replacement cycle.
“We did a cost analysis and found that when you keep machines longer, maintenance costs are a lot higher. Now we do a seven-year rotation, which keeps us within the extended warranty we purchase for the machines,” Pearson said.
He has calculated that a motor grader with a 15-year life costs $47.67 per hour to run, while a machine ￼￼￼￼￼with a seven-year life costs $42.66 per hour. That amounts to an annual savings of $4,509 per machine and $22,545 for the fleet.
“That includes everything—replacement cost, parts, labor, and fuel,” said Pearson.
Figures are based on actual costs to the county during the five years that Pearson has been using Life Cycle Costing. “We return the savings to the fleet. It’s a good investment. We have newer machines, receive a great return, and our maintenance costs are lower,” Pearson said.
By keeping machines for a shorter period, the county is not only saving $5 per hour of operation, the machines are also under warranty for the entire seven years that they are owned by the county.
Motor graders are acquired through lease-purchase agreements with Empire Cat, which include guaran- teed buybacks from the dealer or the option of selling to another party.
“Lately, we’ve been realizing a greater return on our graders than the guaranteed buyback,” said Pearson. “When we resell equipment, it is very well maintained and very well documented.”
Empire services Greenlee County’s motor grader fleet. Service includes S•O•SSM Fluids Sampling. “We receive full reports on everything. We can head off problems before they occur,” said Pearson. “One of the main reasons we go with Cat equipment is the service. That is invaluable to us. If anything happens, they have a facility in the county and are here within an hour.”
Greenlee County is a three and one-half to four- hour drive from Phoenix and Tucson, so reliable equipment is essential.
“Because we’re so remote, we have to have reliable equipment. Identifying issues before they happen is critical for us,” Pearson said.
