Kubota U35: specs & used buying guide
Last reviewed . We review this page periodically for accuracy.
The U35 is Kubota's tight-tail-swing counterpart to the conventional KX-series, designed to work close to walls and obstacles.
Quick answer
The Kubota U35 is a 3.5-ton-class tight-tail-swing compact excavator built to work close to walls and obstacles. In the U35-4 generation it offered roughly 25 gross horsepower and about 9 ft 9 in of dig depth. Because "U35" spans several generations, always confirm which one a listing is.
Key facts
- Machine type: 3.5-ton-class tight/zero-tail-swing compact excavator
- "U35" is a family across generations (e.g. U35-4, current U35-5) — not one machine
- U35-4 engine: approximately 24.8 hp gross / 23.9 hp net
- U35-4 maximum digging depth: approximately 9 ft 9 in (3,010 mm)
- U35-4 operating weight: approximately 3,690 kg (canopy) / 3,830 kg (cab)
Overview
The Kubota U35 is a tight-tail-swing compact excavator in the 3.5-ton class, designed to rotate in confined spaces without the rear overhanging into walls and obstacles. That makes it a favorite for utility, landscaping, and residential work in tight areas.
Crucially, 'U35' is a model family that has spanned multiple generations. The specifications below reflect the U35-4 generation; the current U35-5 and earlier variants differ. Treat any single spec as generation-specific and verify it against the exact unit.
Key specifications
| Machine type | Compact excavator, tight/zero tail swing (3.5-ton class) |
|---|---|
| Engine power (U35-4) | ~24.8 hp gross / 23.9 hp net |
| Maximum digging depth (U35-4) | ~9 ft 9 in (3,010 mm) |
| Operating weight (U35-4) | ~3,690 kg (canopy) / 3,830 kg (cab) |
"U35" refers to a family that spans multiple generations (for example the U35-4 and the current U35-5), not one single machine. The figures below reflect the U35-4 generation; other generations differ. Identify the exact generation and confirm its spec sheet before relying on any single figure.
Figures reflect the U35-4 generation. Other generations (including the current U35-5) differ. Identify the generation of the specific unit and confirm its spec sheet and data plate.
Common applications
- Tight-quarters trenching and excavation near walls
- Utility and drainage work
- Residential landscaping and grading
- Small foundation and footing digging
- Confined-site work where tail overhang is a problem
Strengths
- Tight/zero tail swing for confined work
- Well-regarded reliability in Kubota's compact line
- Good balance of dig performance and compact size
- Broad parts and dealer support
What to check on a used one
- Identify the exact generation — specs and value differ
- Undercarriage wear on tracks, rollers, and sprockets
- Hydraulic leaks and weak functions
- Confirm auxiliary hydraulics for attachments
How hours affect value
As with any compact excavator, weigh hours against service history and undercarriage condition. Generation matters too — an older, higher-hour U35-4 and a newer U35-5 are different value propositions.
Inspection checklist
- Undercarriage: track, roller, idler, and sprocket wear
- Hydraulics: leaks and smooth function on every circuit
- Swing bearing and boom-swing operation (key for tight-swing machines)
- Boom, arm, and bucket pins and bushings
- Auxiliary hydraulics if fitted
- Cold-start, smoke, and hour meter vs records
Maintenance & records to ask for
- Confirm engine and hydraulic service intervals
- Check undercarriage service history
- Ask about any major hydraulic or swing-system repairs
Attachments & transport
Confirm the coupler type and auxiliary hydraulics for thumbs, augers, and breakers you plan to run.
In the 3.5-ton class (roughly 3,690–3,830 kg in the U35-4 canopy/cab), it transports readily on a suitable trailer. Confirm the exact weight for the generation and configuration.
Questions to ask the seller
- Which generation is this (U35-4, U35-5, or other)?
- Does it have auxiliary hydraulics and a thumb or other attachments?
- Are there service and undercarriage records?
- Can I test the boom swing and all hydraulic functions under load?
