Today’s drilling contractors want hard-working rigs that do more than ever before. For drilling rig manufacturers like Watson, the challenge is to continue providing the most productive equipment available to help customers succeed.
“Over the years, holes are getting bigger and deeper, and we’re having to keep pace with that,” says Watson’s Travis Richter, an engineer at the Fort Worth, Texas, company.
Watson customers can be found drilling building foundations, erecting power lines, installing geothermal lines, and drilling in the oilfields. Their need for powerful, responsive drill performance has led to the development of a line of Watson drills powered by John Deere diesel engines.
Mounted on trucks, crane carriers, excavators and crawlers, Watson drills feature John Deere PowerTechTM 4.5L, 6.8L and 9.0L engines ranging from 140 to 325 hp. The company will soon install the first PowerTech PVS 6.8L Final Tier 4 engine on a 3110 drill.
Richter says the performance of John Deere engines has been ideal for Watson applications. “John Deere engines have good peak torque and a reliable flat torque curve,” Richter says. “John Deere also kept the rated rpm at 2400 (with each successive emissions tier), and that’s a big deal when you’re running a transmission behind it. We need that rpm range.”
