The NT35U is the largest machine in the NT range by weight and working envelope. At 3.88 tonnes it runs a Kubota 1703 engine rated at 17.1 kW, with a 0.11 m³ bucket and a 580 mm bucket width. Maximum digging depth is 3071 mm, maximum digging height 4816 mm and maximum digging radius 5355 mm.
It uses steel tracks with two-speed travel (2.3 / 4.0 km/h) and Lickchuan travel and swing motors at a 12 r/min swing speed. The boom swings 68° / 50° left and right — a wider range than the rest of the series, which helps when digging against walls or in trenches. The dozer blade has the longest stroke too: 432 mm maximum digging depth and 345 mm maximum lifting height.
Overall dimensions are 4945 mm long, 1700 mm wide and 2585 mm high, with 300 mm tracks and a 2300 mm track length. A sun canopy is standard. Optional equipment includes engine, cabin, tracks, retractable undercarriage, air conditioner, two-speed motor and hydraulic quick coupler.
