Benefits
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.
Simple Controls
The operator area is spacious and laid out to provide comfort and ease of operation. Smooth, precise operation is possible from easy to use controls allowing all skill levels to be productive with little practice.
Easy Service
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.
Versatility
A range of tools is available to take advantage of the machine's versatility. All tools are matched to the machine to optimize performance and deliver excellent value through high productivity and long life.
