Serviceability: Overall score 8.8 out of 10 Our seven reviewers particularly liked the machine's fuel capacity, giving it a 9.3. Says Karr: "On my previous ma- chine, when I was out all day, I had to bring along a fuel can. This lasts all day." The only serviceability item that scored noticeably low- er on the Case 580 Super N was "access, ease of preven- tive maintenance/500 hour service." This item scored 8.3 while the remaining serviceability features had an average score of 8.9. Performance: Overall score 8.5 out of 10 While respondents were happy with the fuel capacity of the Case 580 Super N, they weren't as impressed with its fuel efficiency or travel speed, which at 7.9 scored notice- ably lower than other performance features. "We road the machine often and it's slow on hills. A little more road speed would be nice," Dowd says. Karr has a different perspective, however: "I like the transmission a lot; every- thing seems peppy. When roading in 4th gear, the machine keeps the engine rpms down and every rpm leads to wear." Dowd also cites the hydraulics and fast cycle times. "It's a smooth machine and I can get back into a hole with no jerkiness." Backhoe lift capacity – a key performance indicator – came in at a high 9.0 as did backhoe bucket height and reach, the push-button, electric diff lock controls and balance over stabilizers. "I've tried others," says one reviewer, "and for what we do, the machine works well. We have the PowerLift, but don't really use it." Operator features: Overall score 8.4 out of 10 Respondents dinged the machine on its in-cab storage room, giving it a 7.6 score. This included Dowd, but he was also pragmatic. "The in-cab storage is limited, but it's a work tool, not a hotel room," he says.

The series includes four machines: our review machine, the 580 Super N; the 580N, 580 Super N WT (wide track) and the 590 Super N. The 14-foot-class, 91-horsepower 580 Super N model replaced the 580 Super M Series 3. Notable changes to the line up included a PowerLift feature that boosts the muscle to the backhoe bucket as much as 65 percent when digging in frost, clay, or root bound soils and when lifting or craning heavy objects. Powershift H-type and Powershift S-type transmissions enable you to shift from the column. A kickdown feature is standard and what Case calls the SmartClutch lets you customize the transi- tion from forward to reverse for smoother direction changes. The backhoe also has a ProControl anti-rebound system as an option that reduces side-to-side jerking when bringing a loaded backhoe bucket to a stop. The geometry of the loader arm was redesigned to increase breakout force and reach to the center of dump trucks along with increasing lift capacity 36 percent. reader reviews | continued " " The in-cab storage is limited, but it's a work tool, not a hotel room
