Bobcat Company’s first Tier 4 loaders feature a non-diesel particulate filter (DPF) engine solution. The final Tier 4 loaders consist of seven medium-sized machines — S510, S550 T550, S530, S570, S590 and T590. The loaders’ 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 4-12% increase in torque. This increase in torque is produced over a wide range of engine RPM.

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 and stops unnecessary engine wear.  

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. 

The 500 frame-size loaders feature a cab-forward design that moves the operator closer to the attachment for improved visibility.

For maintenance, simple check points 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.
