Kubota’s European U17-3α page describes a variable-width track that narrows to 990 mm and expands to 1,240 mm. A procurement spreadsheet that records only the smaller number leaves the machine state unexplained.
Keep both numbers with their labels. The page also distinguishes Standard and Long Arm versions, illustrating why the exact model configuration belongs with any dimensional record. It is not enough for an advertisement to state only U17 or mini excavator.
A dimension is not a site-access decision
The nominal track width does not establish the full clearance required at a doorway, on a route or around an attachment. A buyer or hire customer should provide the actual site question to the supplier and request a configuration-specific drawing and competent assessment. This article does not decide whether a machine can pass through a particular opening.
| Field | Detail needed |
|---|---|
| Model | U17-3α and applicable regional/version identity |
| Width state | Retracted or expanded; keep both catalogue values |
| Supplied configuration | Arm, attachment and other relevant equipment |
| Site question | Actual measured constraint for a professional review |
The cited page is European. Its engine and regulatory description should not be assumed to establish the specification or approval of a machine offered in Southeast Asia. Request the applicable local documents for an actual sale or rental.
No site, machine or clearance was inspected. This guide gives no instructions for changing track width or operating in confined space. Its contribution is keeping the two published states visible so that a narrow-width number is not mistaken for a complete access assessment.
