Benefits

Cat® Customer Value Agreements simplify ownership with planned maintenance, genuine parts, dealer expertise, and smart monitoring to reduce costs and extend machine life. Flexible plans and options for customer‑managed (Convenience plan), dealer‑managed (Performance plan), or protection‑focused (Confidence) coverage.. With Toromont Fast Track, exclusive to Cat® CVAs, you get next‑day parts, two‑day repairs, and Cat® Credits if delays occur—keeping downtime off your schedule.

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
