July/August 2018 | Utility Contractor 29 And while the 1150M represents a compromise between the two size classes of Metts' previous dozers, the company reports that its operating efficiencies resemble that of the smaller of the two dozers it replaced. "The fuel efficiency for this machine is comparable to our older 850K model. We are getting a lot more production for our fuel because of the upgraded Tier 4 engines." Gaining a Competitive Edge "This 1150M is the first piece of equipment that we've bought with machine control," says Metts. "We were at a point we couldn't compete without it. Now we're competitive with anyone else in the area for moving dirt. If we go to a small project, it cuts down a lot of time, nearly eliminating re-work. We aren't moving dirt several times. We can cut it one time and be finished with an area on the project. That was really the big selling point." The Leica Geosystems iGD4SP-3D system with a dual GPS allows for fast and efficient grading with excellent accuracy. "It has the touch screen controller inside, a base station setup on a pole that we mount elsewhere, and we also have a rover to complete whatever staking I need to outside of using the dozer. The dual GPS is much more accurate than any of the laser type control systems that we've used. It follows every contour, most everything we do on the site. We don't have to go back and recheck it. We grade it one time and move onto the next phase." The real benefits of the machine control system are made obvious when accounting for the efficiencies it provides at the end of a job. The goal is to move dirt as few times as possible while putting minimal wear and tear on a machine. "There's always dirt that is going to be moved several times on a job," says Metts. "If you can cut it down to moving it once or twice as opposed to four or five times then you're saving fuel, labor, the insurance costs. The machine control has cut our costs for labor, rework times, our fuel costs, and it's improved our efficiency to where we can take on 20 percent more work in the year. To anyone that does not have machine control on at least one dozer, you can't afford not to." One of the reasons that contractors today may have not yet adopted machine control is a fear of a complicated learning curve or setup. Metts reports that it has helped him improve the overall skill and productivity of his operators without being too difficult to learn. "When we first implemented the system … we spent more time putting parts on the machine than it took to learn to run it. The first guy I put on the dozer for training was a young laborer, 22-years old, who had never been on a bulldozer before. Within an hour I had him grading for curb on a project. It's as simple as it can be. I feel like just about anybody could be trained to be an efficient grader within an hour. We no longer have to have several grade foremen or qualified people to be running the grade control. Even a young laborer can come in and grade a parking lot just as well as anyone else. We're still picking up little tips and tricks here and there, but we we're pretty efficient with it." M Series Dozers Bolster Control, Comfort Another feature of the new setup that has impressed Metts is the 1150M's ability set blade sensitivity, steering sensitivity and shuttle sensitivity to smooth, moderate or aggressive. This allows the operator to adjust machine responsiveness and controls to their preferences and ground conditions. "It took some getting used to – the ability to change the sensitivity and speed of the steering and also to be able to turn the blade control to the fine grade mode," says Metts. "It slows the hydraulic flows down. That was a major help even before we implemented the machine control. The blade control for the dozer does have the ability without the machine control turned on to reduce the flow and slow down the function, so that you don't jerk the blade up and down. It smooths everything out for you." The 1150M features a new cab-forward design with floor- to-ceiling glass doors to provide industry-leading visibility down to the blade. A sloped hood and the position of the operator in the cab provide excellent visibility to the ground in front of the machine. "Visibility is great inside the cab," says Metts. "You're able to see around 18 in. of the end of the blade on both sides. Something that even our older machines with an open cab was a feat. Visibility is very important because of our close quarters work, we grade right up to buildings and you have to be able to see every little thing around them." The 1150M also features a sealed and pressurized cab that helps keep dust and other materials out of the operating environment. Noise is significantly reduced over previous generations, helping to reduce operator fatigue. Finding Support from the Dealer and OEM When it came time to support Metts as his company transitioned to the new dozer with machine control, Hills Machinery out of Columbia, South Carolina, was uniquely qualified to support the deployment as the dealer is a CASE SiteControl-certified precision solutions dealer. "The sales department has been great, the parts department is great, we just didn't feel like there was any need to gamble on another brand," says Metts. The 1150M with machine control is further supported by CASE through its ProCare offering, a suite of product assurances that include a three-year Advanced CASE SiteWatch telematics subscription, a three-year/3,000- hour full-machine limited factory warranty, and a three- year/3,000-hour planned maintenance contract. ProCare allows contractors to invest in new equipment while making owning and operating costs predictable for the first three years of ownership. "The maintenance cost has been virtually nonexistent," concludes Metts. Max Winemiller is global product manager — road building & site preparation for CASE Construction Equipment.
