5 tonne excavators bridge the gap between mini and midi — machines typically in the 4,000-6,500 kg operating weight range, with dig depths of 3.6-4.2 metres and enough hydraulic power to run a full set of civil attachments. They're the largest class that still counts as 'mini', and the smallest that feels genuinely capable on a commercial civil site. For contractors doing mixed residential and light commercial work, the 5 tonne class is the standout choice — it will dig a pool, trench a full driveway worth of drainage, handle stormwater to pit level, and lift reasonable-diameter pipe. Kubota U55, Yanmar VIO55, Caterpillar 305E, Bobcat E55 and Takeuchi TB260 are the most commonly listed models in Australia. Most 5 tonne machines still fit on a standard 3.5-tonne plant trailer (check your trailer's braked capacity), though you start approaching the limits. Used pricing typically sits between $40,000 and $85,000 depending on hours, age, and attachment package. A well-maintained 5 tonne machine from a reputable brand holds value exceptionally well in the Australian market.
