Mustang added a 99-hp Cummins diesel engine to its 2109 skid-steer loader. The Tier-2 emissions-certified, turbo-charged engine offers 305 foot-pounds of torque. The engine offers easy access to important maintenance points, including the dipstick, oil fill and air cleaner. The conventional liquid-cooled design requires oil/filter changes at 500-hour intervals after the initial 50-hour service. A grid-heater glow system provides preheat capabilities, helping operators in cold environments get to work quickly on cold days.
