The flagship 8.4-ton excavator — full-size dig depth with mini-excavator running costs

Questions I get about the KX080-5

The KX080-5 reaches 15'1" deep, which puts it in territory usually reserved for full-size excavators — that's the confirmed current Kubota spec (66.6 HP / 15'1" dig depth), not the older 15'2" / 67.3 HP figures that sometimes still circulate from the prior KX080-4 generation.

At 8.4 tons the KX080-5 delivers depth and power closer to a full-size excavator, but it still runs on mini-excavator-scale fuel burn, maintenance, and operating costs. That combination is why it's positioned as the flagship of the mini-excavator lineup rather than a step into full-size equipment.

Yes, tight tail swing, which matters even more at this size — the counterweight staying within the track width keeps the machine's swing radius manageable on a job site despite its size and reach.

At roughly 18,760 lb, this machine requires a proper deck-over or gooseneck equipment trailer and a truck rated for the combined weight. This is a conversation I'd have directly with you about your hauling setup before you buy.

Cab only — at this size and price point, it comes as an enclosed cab, not a canopy option.
