Bobcat 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 will have a 4% to 12% increase in torque, produced over a wide range of engine rpm, allowing operators of all skill levels to better utilize a machine's 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.
Other features include:
- Machine protection system monitors, manages and shuts down the engine if needed
- Cold weather protection
- Cab-forward design moves the operator closer to the attachment and provides enhanced visibility in all directions
- For simpler maintenance, 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
