Manufacturers say no. In fact, in the Tier 4 Final era, you're getting a better engine and machine all around with little or no sacrifice in performance. Less horsepower, more torque "What you're starting to see is the 100-horsepower machine, the premier machine, with very little compromise, giving the same per- formance at 75 horsepower," says Hurley. "OEMs realized with some adjustments to their transmissions or hydraulics, they could manage it. Most operators can't tell the differ- ence." Hurley cites Deutz's work with a rough-terrain crane manufacturer to adjust the torque curves and minimize the continuous loading of the hydraulics at certain points to achieve what he calls "near zero" changes. "Maybe the only com- promise was 1 or 2 miles per hour on the top speed. That was imme- diately seen as totally acceptable, and as a result, there has been a huge product line coming out at 75 horsepower." "Multiple manufacturers in- cluding Kubota have developed 74.4-horsepower versions of their engines with a high-torque per- formance feature," says Shailes. "The increased costs and applica- tion complexity associated with the 75-horsepower-plus after- treatment led OEMs to accurately evaluate their actual power/torque requirements and led them, in many cases, to be able to use a 74.4-horsepower engine with enhanced torque characteristics. I personally know of OEMs that field tested machines with 74.4-horse- power, high-torque engines where 100-horsepower engines had been previously installed without telling the operators. Almost exclusively the operators did not notice any significant reduction in machine performance." maintenance | continued Call 800-459-SEAT to find a dealer near you.
