The used CAT306E is a compact yet robust excavator, ideal for small-scale construction, landscaping, and utility projects. Powered by a reliable Caterpillar engine (36.5 kW/49 HP), it balances strong performance with fuel efficiency, cutting operational costs. With an operating weight of ~6,100 kg, a max digging depth of 3,800 mm, and bucket capacity 0.18-0.25 m³, it excels in tight spaces—navigating narrow job sites with ease while handling digging, grading, and material handling precisely.
Built to last, its reinforced boom/arm and high-strength steel frame withstand daily wear, even with 3,000-6,000 hours of use (fully inspected and serviced). The operator cab offers ergonomic seating, low noise (≤78 dB), and clear visibility, reducing fatigue during long shifts. Maintenance is hassle-free with accessible service points and Caterpillar’s global parts network. As a pre-owned model, it delivers exceptional value, combining Caterpillar’s legendary durability with affordability—perfect for contractors seeking a reliable workhorse without the new-machine price tag.
