    New Bobcat T450 loader features Tier 4 non-DPF emissions solution, ideal for working in tight areas ​

    (WEST FARGO, N.D. — November 2014) Due to popular demand for a compact track loader in the 400 frame size, Bobcat Company has introduced the new T450. The Bobcat® T450 reintroduces a compact track loader platform size that has not been available from Bobcat Company in recent years. In addition to M-Series enhancements and engine innovations, the T450 features more horsepower, higher auxiliary pressures, lower ground pressure and increased travel speed when equipped with the optional two-speed drive system.

    With a width of just 56 inches when paired with a bucket, the T450 is well-suited for accessing and working in tight jobsites, often replacing tasks previously done with manual labor and tools. The machine’s rubber track undercarriage minimizes ground disturbance — just 4.7 pounds per square inch — to established surfaces for fewer repairs when a project is complete.
    The T450 loader features a radius lift path, providing operators with good reach and visibility. An optional enclosed cab with heat and air conditioning is available for improved operator comfort. Air conditioning is a new option for this size of Bobcat compact track loaders. Also available for the first time in a Bobcat compact track loader this size, a two-speed drive system provides faster travel when desired — with a maximum speed of 7.3 mph in low range and 11 mph in high range.

    The T450 joins the M-Series compact track loader line, which includes the T550, T590, T630, T650, T750, T770 and T870 compact track loaders. All M-Series loaders share features such as improved power and performance, good all-around visibility and outstanding operator comfort.

    Multiple engine advancements
    The 2.4-liter Bobcat engine in the T450 features a non-diesel particulate filter (non-DPF) engine solution. The Tier 4 non-DPF solution was achieved by designing an ultra-low particulate combustion (ULPC) engine. A specially designed engine combustion chamber significantly reduces the amounts of particulate matter. Therefore, Tier 4 emissions compliance can be achieved without using a DPF. In addition to eliminating the need for a DPF, the new engine used in the T450 compact track loader has more horsepower and increased torque. This increase is produced over a wide range of engine rpm, allowing operators of all skill levels to better utilize the machines’ maximum performance.

    For over a decade, Bobcat loaders have been equipped with standard machine shutdown protection that monitors engine and hydraulic functions. Bobcat Company continues to improve these investment-saving features for its customers. Prior to the new Bobcat engine, engine coolant and hydraulic oil temperatures were monitored. If these functions fell outside of their normal operating ranges, the system alerted the operator and shut down the machine to prevent catastrophic damage.

    With the new Bobcat engines, machine shutdown is still included when needed. However, instead of shutdown being the only solution, the system monitors coolant and oil temperatures and manages the engine to prevent them from reaching a point where the machine must be shut down. This helps to prevent engine damage, minimizes engine wear and keeps operators working.

    Another new feature of the Bobcat 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.

    Improved performance
    The Bobcat T450 has increased hydraulic performance, enabling it to efficiently accomplish more work. The hydraulic systems on M-Series loaders have been designed for higher pressure — 3,300 psi — which provides increased attachment performance.

    Hydraulic flow and engine horsepower are matched to the loader’s rated operating capacity, size and weight — producing a loader that can outperform higher-horsepower compact loaders. The T450 is a 61-horsepower machine — which represents a 25 percent increase in horsepower over the loader it replaces. The T450 also stands out from other loader brands with its faster dump and rollback cycle times and higher lift and tilt cylinder forces.

    Cab innovations
    The T450 features a unique cab-forward design that moves the operator closer to the attachment and provides unmatched visibility in all directions. The new loader has the largest cab door opening on the market for easy entry and exit, offering superior visibility to the cutting edge of the bucket and the corners of an attachment.

    Windows on the sides and rear of the cab are larger to provide more visibility to the tracks 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.

    An optional deluxe instrumentation panel monitors key loader functions — including fuel consumption — and the keyless start helps prevent equipment 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.

    T450 owners may choose between standard foot pedal and hand lever controls, the Advanced Control System (ACS) or the optional Selectable Joystick Controls (SJC).

    Increased uptime
    Uptime protections on the new loader are similar to other M-Series models: efficient machine cooling; solid steel tailgate; and improved tie downs. A specially designed rear bumper extends past the tailgate to protect the T450 from obstacles — and related scrapes and bumps — on the worksite. The T450 is designed to work long hours on demanding jobsites with minimal time needed for routine maintenance. Simple checks and superior design make it easier to access systems and perform maintenance correctly at the proper intervals.

    The T450 also features the hydraulically powered Bobcat SmartFAN. The cooling system draws cool, clean air from above and directs it out through two side vents. The radiator and hydraulic oil cooler are located above the engine, well-protected between the frame uprights yet easily maintained.
    An open undercarriage design, constant tension drive belt, protected quick coupler, and improved tie downs are also new features to help increase uptime protection when operating the T450.
