Caterpillar Announces New Cat® D Series Mini Excavators

Cat® 302.4D Mini Excavator Cleaning A Pond

The new Cat® D Series Mini Hydraulic Excavators – models 301.7D, 302.2D and 302.4D are powerful, versatile machines that work comfortably in confined spaces and an addition to the existing D Series line-up. With model configurations that closely reflect their operating weights (1.6 to 2.5 metric tons), the new machines feature powerful hydraulics, a spacious operator environment and excellent service access.

Compact in size, the 301.7D, 302.2D and 302.4D can be easily transported on a trailer, or in a pick-up truck.

The 301.7D can be specified with either a fixed or extending undercarriage. The 302.2D is fitted with an extending undercarriage as standard and delivers a greater dig depth and lifting performance. A longer dozer blade is optional on both the 301.7D and 302.2D.

In North America, the 302.4D is configured with brackets and relief valves for simple and cost effective mounting of a hydraulic thumb.

Cat® 301.7D Mini Excavator Being Lifted For Transportation

Durable, Functional Design

Enhancing overall capability, the dozer blade simplifies backfilling and clean-up chores. A float function allows the blade to follow ground contours with no operator correction and make site clean up quick and easy.

Sturdy hoisting brackets on the cab roof enable the easy and rapid relocation of the machine.

Operator Comfort

D-Series models are available with a canopy operator’s station that enables access from both sides of the machine, or with an optional enclosed cab providing premium standard features such as an efficient heater/defroster/ventilation system, as well as a retractable front window with a strut assisted linkage that can be easily stowed in the roof space. The lower section of the front glass can be raised and stored along with the upper screen section, increasing ventilation and visibility options and providing a quick storage solution.  All models have a sliding right side window for additional ventilation flow. Cab versions come with a radio-ready package.

The spacious operator’s compartment offers a comfortable suspension seat, retractable seat belts, adjustable wrist rests, and ample legroom.

Cat® 301.7D Mini Excavator

The hydraulic function is operated by the proportional roller on the joystick. A switch allows the operator to vary the auxiliary hydraulic flow to suit the requirements of the different work tools. All models offer two-way auxiliary hydraulics enabling the operation of both hydraulic hammer and a bi-directional tool such as an auger.  In line with the larger models in the new Cat excavator range, all controls are pilot operated, providing smooth operation with low effort and eliminating any maintenance required to cables and linkages.

The swing park brake, required during machine transportation, is automatically applied when the left hand console is raised.

Easy Routine Service

Durable steel body panels offer good resistance to damage. Hinged and removable panels provide easy access for both routine and deeper maintenance. Extended routine service intervals for D Series models save time and reduce operating costs: oil-impregnated sintered-alloy bearings in the boom and digging-arm linkages require grease only at 500-hour intervals; engine oil changes are extended to 500 hours; and the hydraulic oil change interval is 3,000 hours. A Cat S.O.S™ fluid-sampling port for hydraulic oil allows accurate, periodic assessment of fluid condition during its life.
