Smoother Roads Ahead - John Deere Industrial Engines

DURABILITY IN HARSH CONDITIONSRock-Solid ResultsA crusher manufacturer loads up on power andtorque — and customer satisfaction — by offeringJohn Deere enginesWhen a CEC crusher arrived Yuma County Road and Bridgein Wray, Colo., with a John Deere diesel engine, they were abit surprised – but not disappointed.The road department had traded in an older CEC model andordered a higher-capacity 133x115 horizontal impact crusher,expecting it to arrive with a competitive diesel engine. But itwasn’t long before the 500-hp PowerTech 6125 engine provedit had all the power and fuel economy they were seeking – andthen some.“There’s more than enough horsepower available to do thejob,” explains Paul Like, road supervisor for Yuma County Roadand Bridge. “When it hits a load, it never pulls down; it loads upand goes.”Construction Equipment Company (CEC) of Tualatin, Ore.,specializes in building portable crushing and screening plantsfor the recycling and aggregate industries. The company recentlybegan offering the John Deere engine on its 133x115 wheelmountedcrusher because the engines are readily available fromtheir John Deere engine distributor and are supported by a networkof John Deere dealers, some of which also serve as CECdealers. But more so, they are impressed by the 500-hp engine’spower and torque performance.“The John Deere engine has an ample amount of powerand torque under full load to operate both the crusher and the100-kW generator that powers the rest of the plant functions,”relates company president Gary Smith. CEC crushers featurea massive rotor and blow-bar weight, allowing the crusher toturn the rotor slower and still transfer the horsepower, makinguse of inertia, rather than speed, to crush the product. “By turningslower, we are getting more impacting and less grinding andmilling, which reduces crusher wear substantially,” explainsSmith. “We are able to can take advantage of the 6125’s flattorque curve at these lower speeds, so when the crusher comesunder heavy load, the engine will walk through it and not lugand cause a voltage droop on the auxiliary generator. In fact,this engine has the power and torque to work in our next largestmodel, the 133x152.”Meanwhile, Yuma County Road and Bridge is relishing awhole new level of productivity and efficiency thanks to its newJohn Deere-powered 133x115. The department recently tookdelivery of several new John Deere graders, as well. Plans are touse the crusher heavily during most of the year, moving it fromsite to site to crush limestone, river rock, gravel, and to recycleconcrete – materials used for road base and surface aggregate oncounty roads. “We are now processing at least 350 tons perhour, and we’re feeding a lot of uneven material through thiscrusher,” says Like, “with the John Deere engine, it sounds likeit’s not even pulling a load.”Engine: John Deere PowerTech 6125H – a 500-hp,6-cylinder, 12.5 L, air-to-air aftercooled diesel engine.Distributor: Cascade Engine Center, LLC, Seattle, Wash.,(206) 764-6850; info@cascadeengine.com.A John Deere PowerTech 6125H engine powers both the crusherand a 100-kW generator on this CEC 133x115 crusher, ownedand operated by Yuma County Road and Bridge in Wray, Colo.Construction Equipment Company recently began offeringJohn Deere power on its larger crushers, reaping the advantagesof ample engine power and torque, dealer servicing, and goodengine availability.PowerSource 3
