The numbers that matter
Built to work, priced to own.
Six reasons this 3.8 ton Kubota machine is the most excavator you can put on a 10,000 lb trailer.
Kubota D1703 diesel
1,647 cc, 24.4 HP, one of the most common small diesels in North America. Filters, belts and parts 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.
Serious hydraulics
17.75 gal/min at 3,553 psi runs a breaker, auger or grapple through the standard auxiliary lines.
Real work, real jobsites.

Dig flush against the wall
Offset the boom and cut tight to a foundation or fence line without moving the tracks.

Pick, place and clear
Stumps, boulders, pipe and demolition debris - the thumb turns the bucket into a grapple.

300 mm rubber tracks and dozer blade
Low ground pressure on lawns and soft ground, and a blade to backfill and grade behind you.
Specifications and what is included
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.

What owners say about this machine
"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."
"Called support twice with spec questions before I ordered and got a real person both times. That is what made me pull the trigger."
