The first models of the new Bobcat R Series loader lineup (the S76 skid steer loader and T76 compact track loader) will be available in early 2020. According to Jorge De Hoyos, senior product manager—loaders, the new R Series models will incorporate significant design changes, compared with their predecessor models. (The S76 and T76 will replace the S650 and T650, respectively.) The R Series, says De Hoyos, was developed around three fundamental criteria: enhanced quality, reliability, and durability; enhanced operator comfort; and enhanced performance.
A major change in design is the use of cast-steel lift arms, replacing the fabricated assemblies of predecessor models. The new lift arms, says De Hoyos, provide 20 percent greater strength than comparable fabricated assemblies, weigh less, allow optimum contours for improved visibility to work tools, allow improved control tolerances, and provide an enhanced match with the coupler. Complementing the cast-steel lift arms, says Bobcat, is the newly optimized geometry of the R-Series workgroup, designed to improve lift capacity throughout the loader’s range of motion and to provide added lift height for dumping into high-sided trucks and hoppers.
The Bobcat R Series cooling system also has been redesigned, with larger components (radiator, hydraulic oil cooler, charge-air cooler, and fan). The new, larger fan is located farther from the operator’s cab and runs at a slower speed (compared with the previous design) to significantly reduce sound levels. A new louvered tailgate allows more efficient air flow into the engine compartment, which features a longitudinally mounted engine with a new cam for reduced emissions. A new vertically mounted fuel tank features a special receptacle for returning hot fuel to optimize fuel-system performance.
According to Bobcat, operator comfort has been improved with features such as ergonomic controls with innovative instrumentation; automatic heat and air conditioning; heated, air-ride seat; and a clear-side-enclosure option to maximize visibility. In addition, says the company, selectable joystick controls with drive-response mode, speed-management system, steering-drift compensation, and horsepower management help reduce operator fatigue. An optional touch display features a full-color 7-inch display, device connectivity, USB power port, and active noise canceling during phone calls.
Both new models feature a one-piece cab that tilts easily for access to major components. The T76 uses Bobcat’s five-link suspension and provides more track on ground than its predecessor. The S76 features electrically-controlled foot pedals to facilitate the cab-tilt feature.
