Five metric tons and zero tail swing is a combination that does not come from many manufacturers as consistently as Kubota delivers it in the U55. This machine handles utility trenching, pool excavation, residential footings, and light commercial grading in the same workday, swapping applications through the same crew without a machine swap. Operating weight is around 12,200 lbs, dig depth reaches about 12.5 feet, and the U-series designation means the tail stays inside the track footprint through a full rotation cycle. That is the machine's defining trait and the reason contractors choose it over larger conventional tail-swing units for access-constrained jobs.
U55s price from about $75k to $95k new and $45k to $65k in the used market for clean lower-hour units. We handle application-only financing up to about $400k, which means every U55 transaction fits the streamlined path. Kubota excavators have a strong secondary market presence, which gives lenders confidence in collateral value and keeps advance rates competitive on both new and used equipment. Submit a one-page application, the machine quote, and three months of bank statements, and we typically have an answer within a business day.
U55 Specs and Where the Machine Earns Its Keep
Kubota's U55-4 (fourth generation) runs a Kubota V2607 four-cylinder diesel producing around 45 horsepower. Bucket digging force is approximately 11,600 lbs-force, which gives it meaningful productive force for a 5-ton machine. The arm crowd force adds about 7,400 lbs. Those numbers translate to consistent productivity on dense soil, clay, and packed gravel without the machine struggling. The standard two-speed travel system lets the operator shift between low torque and higher travel speed without stopping the machine, which matters when repositioning between trench sections on longer utility runs.
The auxiliary hydraulic circuit on the U55 supports attachments including hydraulic thumbs, breakers, tiltrotators, and compaction wheels. Contractors running the U55 for utility and pipeline work often run a hydraulic compaction wheel after backfill to achieve spec-grade compaction in narrow trench cuts, avoiding the need for a separate walk-behind compactor on tight utility installations. The hydraulic breaker compatibility opens up concrete and rock breaking applications that extend the machine's job-site utility well beyond standard dirt work.
Kubota's worldwide dealer density is one of the U55's practical advantages. Parts availability, warranty service, and certified technician support follow the machine wherever it works, which is why contractors in rural markets who might struggle with support for less-common brands specifically choose Kubota for remote job sites.
New U55 vs. Used: Financing Considerations
A new U55 from a Kubota dealer includes factory warranty coverage and the latest hydraulic and engine calibration. Buyers who want to maximize the Section 179 deduction in a tax year benefit from a new purchase placed in service before December 31. Section 179 expensing allows the full purchase price to be deducted in the year of purchase up to the applicable limit, rather than spread over the machine's useful life. Your tax advisor can confirm whether the deduction applies to your specific business situation.
Used U55s with 1,500 to 3,000 hours are a strong buy in most markets when the maintenance history is verifiable. Kubota's U-series machines have a reputation for longevity, and a well-maintained U55 at 2,500 hours is not a risky asset. Used excavator financing on Kubota equipment follows the same application-only path as new equipment for deals in this price range, and lenders are comfortable advancing against used U55 value when the title is clean and the machine can be inspected.
Timeline and What to Expect
A clean U55 deal from application to funded runs about one to two weeks. The sequence is: application and documents submitted, lender matched and credit reviewed, approval issued, digital documents sent and signed, and funding released to the dealer or seller. The bank statements are the one piece that most applicants forget to have ready, and gathering them before starting the process shaves a day or two off the total time. Three consecutive months, with all pages, is the standard requirement.
For residential site builders who need the machine by a specific project start date, communicating that deadline early lets us prioritize the deal. We cannot guarantee timelines on files that need additional documentation or have credit complexity, but a clean file on a standard U55 transaction is not a complicated underwriting problem, and most lenders in our network know the machine and treat it straightforwardly.
Comparing to the larger Kubota model in the lineup, the Kubota KX040 is a step down at 4 metric tons. The U55 takes on bigger jobs with more digging force and a deeper bucket, while the KX040 handles the tighter access work where the U55's slightly wider footprint is a constraint.
