WEST FARGO, N.D. — Bobcat Company has released its first Tier 4 loaders — including a non-diesel particulate filter (DPF) engine solution. The seven medium-sized machines make up the most popular size class in the Bobcat® loader family and provide operators with all of the same performance benefits of the previous interim Tier 4 models.The Tier 4 Bobcat non-DPF solution was achieved by designing an ultra-low particulate combustion (ULPC) engine. The ULPC is accomplished through a specially designed engine combustion chamber that significantly reduces the amounts of particulate matter created during combustion. Therefore, Tier 4 emissions compliance can be achieved without using a DPF.In addition to eliminating the need for a DPF, the new engines used in 500 frame-size loaders will have 4 to 12 percent increase in torque. This increase in torque is produced over a wide range of engine rpm, allowing operators of all skill levels to better utilize the machines’ maximum performance.The S510, S550 and T550 feature a radius lift path, providing operators the reach and visibility they require for dumping over a wall, backfilling or loading flatbed trucks. The S530, S570, S590 and T590 models feature a vertical lift path, providing operators the ability to lift heavier loads higher, making it easier to clear high-sided truck boxes and hoppers, as well as placing pallets.The new Tier 4 loaders feature a machine protection system that monitors, manages and shuts down the engine if needed. This system monitors engine coolant and oil temperatures and will manage engine systems to reduce the potential of these fluids reaching a point where the machine has to be shut down. This minimizes potential damage to the engine, stops unnecessary engine wear and keeps operators working. Another new feature of the skid-steer and compact track loader line is cold weather protection. Anytime the engine temperature is too low, the loader will temporarily limit the maximum engine speed (rpm) to prevent premature component wear or failure. Engine idle speed is also raised slightly to help the engine reach its operating temperature faster. As soon as the engine warms up to a predetermined temperature, the protection mechanism will deactivate. Cab-forward design provides industry-leading visibility to work areasThe 500 frame-size loaders feature a unique cab-forward design that moves the operator closer to the attachment and provides unmatched visibility in all directions. The new loaders tout the largest cab door opening on the market, offering superior visibility to the cutting edge of the bucket or the corners of an attachment.Windows on the sides and rear of the cab are larger in size to provide more visibility to the tires and back of the machine. The larger top window makes it easier and more comfortable for the operator to see an attachment with the lift arms raised, an advantage when loading trucks or performing other tasks.Easier maintenance improves productivityOperators want to spend minimal time on routine maintenance to start the workday earlier, and the loaders are designed to work long hours in demanding conditions. Simple check points and superior design make it easier to perform maintenance correctly at the proper intervals. The auxiliary hydraulic quick couplers are mounted directly to the front plate of the lift arm to provide a solid mounting, and hoses are routed through the loader arms for better protection.Operator comfort is kingComfortable operators are more productive, so to create a better working environment, The 500 frame-size loaders feature a large cab, redesigned interior and improved cab pressurization. The loaders have a best-in-class pressurized cab with a new one-piece seal that goes all the way around the door and fits into a special curved pocket. This minimizes the amount of dirt and dust that might enter the cab, creating more enjoyable working conditions and making it easier to clean the cab.Operators also have the choice between standard foot pedal hydraulic controls, the Advanced Control System (ACS) or the Selectable Joystick Controls (SJC) on all machine models.The best of both worlds: hydraulics and horsepowerThe hydraulic systems on M-Series loaders have been engineered for higher standard flow and pressure, which provides increased attachment performance. Engine horsepower and hydraulic flow are matched to the loader’s rated operating capacity, size and weight — producing a loader that can outperform higher-horsepower compact loaders. Available only on M-Series loaders, the optional deluxe instrumentation panel intelligently monitors key loader functions — including fuel consumption — and the keyless start helps prevent theft. The 5-inch, full-color LCD screen offers better readability and operator interaction. Easy-to-read virtual sweep gauges allow operators to quickly read and understand the machine’s performance.ABOUT BOBCAT COMPANYBobcat Company, headquartered in West Fargo, N.D., is a worldwide leader in the manufacturing and distribution of compact equipment.
