E-quipment highlight: Kubota mini excavator goes from diesel to EV and back

Japanese equipment giant Kubota brought 22 new or updated machines to the 2025 bauma expo earlier this year, but tucked away in the corners was a new retrofit kit that can help existing customers decarbonize more quickly, and more affordably.

No matter how badly a fleet may want to electrify, harsh economic realities and the greater up-front costs typically associated with battery electric remain high hurdles to overcome, but new retrofit options from major manufacturers are popping up to help lower those obstacles.

The latest equipment maker to put its name on the retrofit list is Kubota, who says its kit can be installed by a trained dealer in a single day.

That’s right! By this time tomorrow, your diesel-powered Kubota KX019 or U27-4 excavator (shown) could be fitted with an 18 or 20 kWh li-ion battery pack and electric drive motors and ready to get to work in a low-noise or low-vibration work environment where emissions are a strict no-no. Think indoor precision demolition or historic archeological excavation.

Then, if necessary, it can go right back to diesel power.

From diesel to electric and back again

If that sounds familiar, that’s because we’ve talked about a similarly flexible power solution from ZQUIP. The battery packs and diesel engines are much larger in that application, but the basic sales pitch remains the same: electric when it benefits your operation, diesel it doesn’t.

Kubota says its modular retrofit kits is a response to the increasing global demand for sustainable alternatives by focusing on making machinery that’s flexible and repairable enough to be “reusable,” and offer construction fleet managers a longer operational lifespan, superior ROI (return on investment), and lower TCO (total cost of ownership) than the competition.

Kubota’s solution also notably reduces maintenance costs and operational overheads. With no engine and associated components, servicing time and expenses are considerably reduced, saving customers both time and money. Additionally, with electricity costing far less than fossil fuels, it offers a highly economical advantage.

International Rental News reports that other changes to the excavators include a more modern cab controls with a digital instrument cluster, a 60 mm wider undercarriage for more stability, and an independent travel circuit allows operators to use the boom, dipper, bucket, and auxiliary functions without an impact on tracking performance.

Kubota’s new kit, first shown at last year’s Hillhead exhibition in the UK, will officially be on sale this summer – any day now, in fact – though pricing has yet to be announced.

Electrek’s Take

If you’re wondering how it is that we’re still talking about bauma 2025 a full quarter after the show wrapped up, then I haven’t done a good enough job of explaining how positively massive the show was. Check out this Quick Charge episode (above) then let us know what you think of Kubota’s modular power kits in the comments.
