Compact Dimensions

Compact Dimensions

With an overall width of only 730 mm (2 ft 5 in) the Cat® 300.9D can easily drive through narrow passages and doors. Both indoor and outdoor jobs are now accessible with the under 1000 kg (2,205 lb) weight making easy trailer transportation between sites possible.

Extending Undercarriage and Blade

An extending undercarriage and fold out dozer blade allow the machine to be configured for excellent working stability and optimum performance. Easy retraction, controlled from the operator's seat, enables the machine to pass through narrow openings.

Foldable Safety Frame

A protective ROPS safety frame structure mounted on the front of the machine allows fitting of a guard for extra operator protection during hammer use. The structure folds down in a few seconds for easy machine transportation and storage.

Performance and Durability

Powerful Engine and Hydraulics

The 13.7 kW (18 hp) engine and perfectly matched hydraulics provide efficient, economical and reliable performance for the toughest of jobs. The matched cooling system is designed to accommodate working within confined areas and also the powerful Cat® hammer. Low noise and vibration levels deliver comfortable operation.

Hose and Cylinder Protection

Bucket hoses are well protected within the boom and the cylinder is mounted above the structure to increase the machines durability for working in tough environments. The clean lines of the front linkage also provide excellent visibility to the digging area.

Auxiliary Hydraulics as Standard

The 300.9D is fitted with auxiliary lines for hammer operation routed down to the stick. Locating the connecting point close to the work tool reduces connecting hose lengths and potential for damage.

User Friendly Operation

Simple Controls (Ease of Use)

The operator area is spacious and laid out to provide comfort and ease of operation. Smooth, precision operation of functions is possible from independent controls allowing all skill levels to be productive with little practice.

Extending Dozer Blade

Blade extensions simply rotate and lock into position allowing the machine to be quickly configured for narrow width or maximum blade coverage. Locking pins and extension plates are retained with the machine to reduce potential for lost or damaged components.

Serviceability

Service and maintenance time is reduced to a minimum with a simple to open steel engine cover and all maintenance and greasing points easily accessible.
