The 300.9D weighs in at just 935kg (2061 lbs), making it the smallest machine in the Caterpillar range. With an overall width of just 730mm (28.7 in), this machine is capable of driving through a standard doorway, providing easy access to the most confined job sites. This will prove popular with homebuilders, rental companies and demolition contractors.

A powerful water-cooled three-cylinder diesel engine produces 13.7kW (18.4 hp); along with a twin gear pump hydraulic system creates a maximum arm crowd force of 4.5kN (1011 lbf) and a maximum breakout force of 8.9kN (2000 lbf). The machine comes equipped with an extending undercarriage and fold-out dozer blade, ensuring maximum stability and allowing a digging depth of up to 1,731mm (69.4 in) and a maximum excavation radius of 3,074mm (121.7 in).

A foldable overhead protective structure is mounted on the front of the machine, allowing the fitting of an additional guard to protect the operator when the machine is used with a hydraulic breaker. Auxiliary hydraulic lines with quick disconnect fittings are supplied as standard, with two-way hydraulic flow available as an option. Caterpillar’s work tool division will be introducing a new compact breaker specifically to work with this smaller machine.

A spacious operator area with easy to use controls ensures the 300.9D will be a popular choice with operators of all abilities. The folding structure and operating weight well below 1 tonne, makes the 300.9D easy to transport on a trailer behind a van or 4x4, while a simple single steel engine cover provides easy access to all service and maintenance points.
