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.

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.
