Detailed Specifications Breakdown
Engine
• Model: Kubota D1803-CR-E4
• Type: 4-Cylinder, Liquid-Cooled, Diesel
• Displacement: 1.8 L (112 cu in)
• Power: 35.8 kW (48.0 HP) @ 2200 rpm
• Emission Standard: Tier 4 Final (without a DPF - Diesel Particulate Filter). Kubota achieved this through an advanced EGR (Exhaust Gas Recirculation) and DOC (Diesel Oxidation Catalyst) system, which is a significant selling point for this model.
Weights and Dimensions
• Operating Weight: 3,850 kg (8,488 lb) - This is the typical weight with a standard bucket and cab.
• Transport Length: 4,770 mm (15 ft 8 in)
