Yanmar has been building compact excavators for decades. In fact, the company traces its mini-excavator history back to 1968, when it developed what it describes as the world's first self-propelled mini excavator. Yanmar later introduced the world's first zero-tail-swing mini excavator in 1993, a design concept that has since become common throughout the compact equipment industry.
The Yanmar ViO35-7 represents the latest generation of that experience in Yanmar's 3.5-ton mini-excavator class. With 24.4 horsepower, True Zero Tail Swing, an 11-foot-3-inch maximum digging depth, 17 GPM of auxiliary hydraulic flow, and an operating weight approaching 7,900 pounds, the ViO35-7 is one of the most capable machines in the 3.5-ton class. Below, we'll break down the full specs, standard features, competitor comparisons, and buying tips to help you decide if it's the right mini excavator for you.

Undercarriage, Tracks & Dozer Blade
The ViO35-7 is built on a heavy-duty undercarriage designed for everyday jobsite use, with steel-sleeved hose guards helping protect vulnerable components from debris and impacts. The machine measures approximately 68.5 inches wide with 12.6 inches of ground clearance and comes standard with 85-inch-long by 11.8-inch-wide rubber tracks, while steel tracks are available as an option. Ground pressure remains relatively low at approximately 4.44 PSI with the canopy and 4.64 PSI with the cab, helping distribute the machine's weight across the job site.
Travel Speed: ViO35-7 vs. ViO35-6
The ViO35-7 also uses a two-speed travel system with a maximum speed of approximately 3.0 mph. It can automatically shift between high and low range as the workload changes, providing additional traction when climbing grades or pushing material before returning to high range when the load decreases. Compared with the previous ViO35-6, Yanmar reports the -7 generation is 7% faster when traveling without a load and up to 25% faster under load.
68.5-Inch Dozer Blade
At the front, the standard 68.5-inch dozer blade raises approximately 16.7 inches above ground level and lowers about 14.6 inches below ground, giving operators plenty of adjustment for grading, backfilling, trench cleanup, and site preparation. An optional angle blade is also available for operators who regularly grade, windrow material, or backfill trenches. Yanmar also redesigned the lower body and bucket geometry on the -7 generation to significantly reduce the gap between the bucket and blade, making it easier to pull material close to the machine during cleanup.
Hauling the ViO35-7: Trailer & Truck Requirements
Before you buy, plan how you'll move it. The ViO35-7 weighs 7,540 lbs. with a canopy and 7,882 lbs. with a cab, before adding a bucket, thumb, other attachments, or the optional 364-pound counterweight. Multiple tie-down and anchor points help simplify transport, but your trailer and truck need to be rated for the complete transported weight.
Once you account for the trailer's own weight and your attachments, a 10,000-lb. GVWR trailer usually doesn't leave enough payload capacity. Many owners haul a 3.5-ton mini excavator on a 14,000-lb. GVWR equipment trailer pulled by a properly rated 3/4-ton or 1-ton pickup. Always confirm your truck's towing capacity, hitch rating, and combined weight rating before hauling. For commercial use, a combination with a gross combined weight rating of 26,001 lbs. or more and a trailer rated over 10,000 lbs. generally requires a Class A CDL, so check your state's DOT requirements.
Boom, Arm, Hydraulics & Attachments
The ViO35-7's compact design continues through the boom and arm, with 71 degrees of left swing and 52 degrees of right swing for working close to buildings, foundations, fences, and other obstacles. Hydraulic hoses are routed through protected areas near the boom foot, while hose guards, spring-steel cylinder rod guards, and an integrated boom work light add protection in demanding jobsite conditions.
Hydraulic performance is another strong point. The ViO35-7 uses two variable-displacement piston pumps and a gear pump, allowing operators to travel, swing, position the boom, and dig smoothly at the same time. Maximum auxiliary hydraulic flow is approximately 17 GPM, with an optional second auxiliary circuit available for attachments requiring additional hydraulic control.
ViO35-7 Digging Specs
The ViO35-7 also provides a strong working envelope for its size:

Lift Capacity & Attachment Presets
Lift capacity varies with boom position, reach, blade position, and lifting direction, but under favorable conditions with the blade down and the load positioned over the front, the ViO35-7 can lift close to 4,000 pounds at ground level, depending on reach. The 4.3-inch display can also save up to five auxiliary-flow settings, making it easier to switch between hydraulic attachments without repeatedly adjusting flow requirements.

Upper House, Zero Tail Swing & Operator Station
One of the ViO35-7's defining features is its True Zero Tail Swing design. The upper structure stays within the width of the tracks as the machine rotates, helping reduce the chance of contacting walls, fences, vehicles, or other obstacles when working in confined spaces. The machine has a 34.3-inch tail-swing radius and an overall height of approximately 96.9 inches.
The ViO35-7 is available with either an open canopy or enclosed cab, with operating weight varying by configuration:
7,540 lbs. — canopy
7,882 lbs. — enclosed cab
An optional 364-pound counterweight and rearview camera can also be added depending on the application.
Cab, Visibility & Operator Comfort
Visibility is another area Yanmar improved on the -7 generation. Large windows provide a broad view around the machine, while a rounded overhead roof window improves visibility of the boom.
The enclosed cab adds heating and air conditioning, along with a more open floorboard, redesigned travel pedals, reduced interior noise, and improved HVAC airflow compared with the previous ViO35-6. Operator conveniences include a reclining suspension seat, USB and 12-volt charging, cup holder, phone and tablet storage, additional storage trays, and joystick-mounted auxiliary controls.
Primary functions such as blade operation, throttle adjustment, hydraulic controls, and the safety lock are positioned within easy reach.
4.3-Inch Monitor & SmartAssist Remote Telematics
A 4.3-inch color LCD monitor displays operating information, warnings, maintenance data, diagnostic codes, and machine settings. It can also manage features such as auxiliary hydraulic flow, Eco Mode, and Auto Deceleration, while saving up to five attachment-specific hydraulic settings.
The ViO35-7 also includes five years of Yanmar SmartAssist Remote, giving owners access to machine location, operating status, maintenance intervals, diagnostic information, geofencing, and theft-monitoring features.
Engine, Efficiency & Maintenance
Power comes from Yanmar's 3TNV88F-ESBV4, a 24.4-horsepower, three-cylinder, water-cooled direct-injection diesel engine rated at approximately 2,200 RPM. The North American ViO35-7 also does not require a diesel particulate filter (DPF), eliminating DPF regeneration from the normal maintenance routine. Fuel capacity is approximately 11.6 gallons.
Eco Mode & Auto Deceleration
Yanmar pairs the engine with several systems designed to improve efficiency and keep power matched to hydraulic demand. Auto Deceleration lowers engine speed after more than four seconds of inactivity and returns it to the previous setting when a control is moved, while Eco Mode reduces engine speed during lighter work. Engine and hydraulic controls also work together under heavier loads to help prevent unnecessary engine bogging.
Maintenance & Warranty
Routine maintenance is straightforward, with a tool-free rear hood providing access to the engine, belts, cooling system, and other major service points. A side-by-side radiator and oil-cooler arrangement with a removable fine-mesh screen helps keep debris away from the cooling cores and makes regular cleaning easier. The ViO35-7 is backed by Yanmar's 4-year/4,000-hour factory machine warranty, providing long-term coverage for owners using the machine in demanding applications.
Yanmar ViO35-7 Price & Availability
How much does a Yanmar ViO35-7 cost? Like most compact excavators, the ViO35-7 is sold through dealer quotes rather than a single national sticker price. Your final price depends on cab or canopy, rubber or steel tracks, blade setup, auxiliary hydraulics, attachments, financing, and current Yanmar promotions, so the best way to get an accurate number is to quote the exact configuration you need.
