3.5t Compact Excavator

The RE35U is a 3.5 ton compact excavator built around a Kubota 1703 diesel engine rated at 18.2 kW, meeting both EPA Tier 4 and Euro 5 emission standards. At 1,700 mm wide with rubber tracks, it fits through standard gates and doorways, which makes it practical for residential foundation work, indoor demolition, and landscaping jobs where a full-size machine cannot operate.

The boom offers a hydraulic offset angle of 68 degrees left and 50 degrees right, letting the operator dig parallel to walls and foundations without repositioning the machine. With a maximum digging depth of 3,071 mm and a digging radius of 5,355 mm, the RE35U handles trenching, footing excavation, and material handling on sites where space is tight. The short tail swing radius of 857 mm means the counterweight stays within the track width during rotation, reducing the risk of collision when working near walls or in narrow alleys.

Operators work from an enclosed cab with joystick controls, an adjustable suspension seat, and optional air conditioning. Based on feedback from contractors using this model in Southeast Asia and the Middle East, the cab layout reduces fatigue during 8-hour shifts compared to open-canopy configurations on smaller machines. For buyers evaluating our crawler excavator series, the RE35U sits between the 2.6-ton RE26U and larger 6.5-ton models, filling the gap when a mini excavator lacks digging depth but a 6-ton machine is too heavy for soft ground or finished surfaces.

The machine ships with rubber tracks as standard (300 mm width) for use on pavement and finished surfaces. Steel tracks are available as an option for muddy or rocky conditions. A telescopic chassis frame allows the track width to extend for additional stability during deep digging, then retract for transport through narrow passages.

What This Machine Does Well

Trenching for utilities is the most common job this model handles. At a digging depth of just over 3 meters, it reaches below the frost line in most temperate climates and accommodates standard drainage pipe diameters. Contractors in the Philippines have reported completing 40-50 meters of 600mm-deep trenching per shift in compacted soil, which is roughly 30% faster than a 2-ton machine on the same job due to the larger bucket and higher hydraulic flow.

Foundation excavation for small residential buildings is the second scenario where the RE35U performs well. The 5,355 mm digging radius covers a 3-meter-wide foundation trench from one side, reducing the number of times the operator needs to reposition. The dozer blade at the front grades the spoil pile while digging, which saves a separate pass with a hand tool or skid steer.

Where This Machine Reaches Its Limit

If your primary work involves digging below 3 meters (deep utility lines, basement excavation), the RE35U will need to be repositioned frequently or supplemented with a larger machine. For loads exceeding 1,200 kg in the bucket (large rocks, concrete chunks), the hydraulic system reaches its relief pressure and the boom will not lift further. This is not a defect - it is the designed safety limit for a 3.5-ton class machine. For projects requiring regular handling of heavy materials, consider our 6.5-ton model instead.

Soft ground is another consideration. At 3.5 tons with 300mm tracks, the ground pressure is approximately 31 kPa. This works on most firm soil and gravel but the machine will sink in soft mud or uncompacted fill. If your site has soft ground conditions, request the 450mm wide track option, which reduces ground pressure to about 22 kPa.

Engine and Emissions

The Kubota 1703 is a 3-cylinder diesel engine that has been used in compact construction equipment for over a decade. Parts are available globally through Kubota's dealer network, which matters if your project is in a remote location. The engine meets EPA Tier 4 and Euro 5 without requiring a diesel particulate filter (DPF), which reduces maintenance complexity and eliminates the risk of DPF clogging during low-load operation.

Fuel consumption at rated load is approximately 3.2 liters per hour. In typical intermittent digging operation, actual consumption runs 2.0-2.5 L/h. The 52-liter fuel tank provides a full day of operation without refueling under normal working conditions.
