4 Ton Kubota Diesel Mini Excavator with Hydraulic Thumb and A/C Cab
Machine details
The 3800 UF is the machine you buy when a 1-2 ton digger is too small and a full-size excavator is too much. A 3.8 ton (8,377 lb) operating weight, a Kubota D1703-E4B 24.4 HP diesel, an enclosed cab with air conditioning, a factory hydraulic thumb and a side swing boom put real contractor capability in a footprint that still fits through a 67 inch gate. Dig to 131 inches (3.32 m), reach 219 inches at ground level and load a truck from 138 inches up, all day, in a climate-controlled seat.
It is built for property owners with acreage, farms, landscapers, fencing and drainage crews, utility contractors and municipal teams who would rather own a machine than keep renting one. Brand new, crated, and delivered free by LTL freight to the contiguous 48 states.

Eight reasons this machine wins
- Kubota D1703 diesel. 1,647 cc, 24.4 HP, one of the most common small diesels in North America. Filters, belts and parts are available at any Kubota dealer.
- 131 inch dig depth. Deep enough for water lines, septic laterals, footings and 8 foot trenches without a bigger machine.
- Hydraulic thumb from the factory. Grab rocks, stumps, logs, pipe and demolition debris without buying and plumbing a thumb later.
- Side swing boom. Offset the boom and dig flush against foundations, fences and curbs without repositioning the tracks.
- Enclosed A/C cab. Heat, cold, dust and rain stay outside. Operators stay productive for the full shift.
- Pilot controls and dual-speed travel. Smooth, low-effort joysticks and a high range for moving across the site.
- Serious hydraulics. 17.75 gal/min at 3,553 psi runs a breaker, auger or grapple through the standard auxiliary lines.
- Trailer-friendly. 67 inches wide and 100.5 inches tall, so it moves on a 10,000 lb class equipment trailer behind a 3/4 ton pickup.
In the field
- Utility and drainage trenching - water, sewer, electrical conduit, French drains and culverts.
- Foundations and footings - basements, additions, retaining walls and pier holes.
- Land clearing - stumps, brush and rock with the hydraulic thumb.
- Farm and ranch - fence lines, ponds, stock tanks, irrigation and manure handling.
- Landscaping and hardscape - grading pads, moving boulders, planting mature trees.
- Demolition and municipal work - sidewalks, small structures, storm drain repairs.

Owner feedback
★★★★★ 4.8 / 5 average owner rating
"Crated exactly as described and the freight company called ahead for the appointment. Uncrated it in the driveway and it started on the first turn."
"Kubota engine, standard filters, nothing exotic. I service it myself in the shop. For the money there is nothing close on the market right now."
"The swing boom is the reason I bought it. I can dig tight to the foundation on a 4 foot side yard without moving the machine every two feet."
