Parts Compatible with the Kubota U27-4 Mini Excavator

The U27-4 is the 2.7 ton class entry in Kubota's current 4 Series minimum tail swing mini excavator lineup. It sits between the U17 sub-2-ton and the U35-4 3.5-ton machines, hitting the popular 2.5 to 3 ton size class that dominates residential and small-contractor work. The U27-4 succeeded the U25 with Tier 4 Final emissions compliance via the D1503-CR common rail engine, refreshed cab and operator station, and updated hydraulic auxiliary plumbing. The minimum tail swing design makes the U27-4 a popular choice for tight residential applications including driveway repair, foundation work, and yard utility installation.

Many U27-4 service parts cross to the U35-4 (the 3.5 ton sibling in the same 4 Series minimum tail swing line) because Kubota engineered the 4 Series minimum tail swing line with shared cab, electrical, and hydraulic plumbing across the size range.
