Six replacement models and two updated models comprise the new D series Cat compact track loader line. The units have redesigned cabs and lift arms. Replacement models include: mid-size frame 257D Multi Terrain Loader (MTLs feature a second level of suspension with torsion-axle mounting of the roller bogie wheels) and 259D CTL. Larger frame models are the 277D and 287D MTLs and the 279D and 289D CTLs. The largest D series models, the 299D and 299D XHP CTLs, have been given the series’ new cab and a new lift arm design. The cab is of one-piece modular design that allows doubling the cab pressurization in the previous design. The HVAC system supplies 20 percent more airflow and about a 50 percent increase in heating and cooling rates. Lift arms now have a tubular design that improves sight lines. Other cab improvements include an optional high-back, heated, air-suspension seat with integral seat-mounted joystick controls. An electronic dial-type throttle permits precise rpm settings, the company says, and a new throttle-smoothing feature monitors accelerator-pedal movement under the operator’s foot when the machine is traveling over rough terrain, and it then clips the extremes of pedal travel to yield steady, even travel speeds.
