In the transition to Tier 4-Final/Stage IIIB emissions compliance, Caterpillar boosted horsepower and torque on the 226D and 232D skid steers and 239D and 249D compact track loaders 10%, and expects up to a 14% improvement in fuel efficiency compared to predecessor models. The 67 hp C2.2 engine uses an electronically controlled high-pressure/common-rail fuel system, direct fuel injection, and a maintenance-free diesel oxidation catalyst as the only required exhaust after treatment.

The four new D Series small-chassis loaders incorporate design innovations pioneered on the larger D Series machines, including a sealed/pressurized cab, electro-hydraulic controls, redesigned lift arms, premium seat choices, and optional Advanced Display (available with rear-view camera).

  • Two-speed drive with 226D and 232D top speed of 11 mph
  • 239D and 249D CTL operating weights less than 8,000 lbs. allow trailering without a CDL
  • Radial-lift 226D and vertical-lift 232D rated operating capacities (ROC): 1,550 and 1,850 lbs.
  • Radial-lift 239D and vertical-lift 249D ROCs: 2,050 and 2,300 lbs.
  • Demand fan is standard for optimum cooling and reduced horsepower draw

Cab One

The D-Series cab (Cab One) is completely modular and self-sealing, leaving no part of the cab attached to the chassis when the cab is tilted.

  • Redesigned HVAC system supplies 20% more airflow and an approximate 50% increase in heating and cooling rates
  • Standard monitor's single-code security feature deters theft and unauthorized operation
  • Advanced Display expands security (operator) codes to 50 and can store custom operating preferences for each code
  • Operator preferences include response rates for hydrostatic drive and implement hydraulics, settings for ride-control, creep speed, and top speed
  • A master code allows review of operator-specific machine information, including hours of operation, fuel burn, operating events, and diagnostic codes

Intelligent self-leveling

Small-chassis D Series loaders feature the electronic Intelligent Leveling system that includes:

  • Dual self-leveling automatically levels loader linkage while raising or lowering the arms
  • Automatic snubbing cushions lift-arm descent, slowing motion as the arms approach the stops
  • Return-to-dig allows the operator to set the digging angle of the bucket and automatically return the bucket to that angle by pressing a trigger on the joystick as the arms lower
  • Work tool positioning allows the tool angle to be pre-set, as when positioning a trencher, and the angle automatically recalled if the machine is repositioned

Lift arms, coupler, track choices

Lift arms for all D Series machines are a tubular steel that provides optimum lift characteristics and strength, with a narrower profile for improved sight lines to the sides of the machine and the work tool.

  • Available automatic work-tool coupler is electrically actuated, replacing the previous hydraulically actuated coupler
  • Available high-flow auxiliary-hydraulics provides flows to 26 gpm and pressures to 3,336 psi
  • Standard and high-flow auxiliary hydraulics use connect-under-pressure quick disconnects
  • Suspended-undercarriage CTL models offer 15-in.-wide tread in addition to standard, 12.6-in.-wide tracks


The new models feature ground-level access to all routine service points, including filters, battery, and engine-oil fill and check points.

  • Air-conditioner condenser mounted inside the engine compartment door for easy cleaning or service
  • Electric fuel-priming pump with automatic air bleed eases replacing the fuel filter/water separator
  • Dead-engine/boom-down actuator repositioned for easier access
  • Boom arms incorporate a one-person safety brace, and a battery disconnect is optional
