And this year, all -5 generation models are outfitted with standard technology and comfort packages, plus more tech options for ultimate customization,” said Patrick Baker, Kubota construction equipment product manager. “Our new excavator models are built on the solid engineering our customers expect, and now feature more technology, much quieter cabs and many comfort features, we are truly taking care of our operators with these new units.”
