Iseki TU1400 TU1401 TU1500 TU1501 TU1600 TU1601

Knowledge base for the Iseki TU1400, TU1500 and TU1600 (00-series) and their successors TU1401, TU1501 and TU1601 (01-series), each also available as 4WD F-version. These compact mini tractors run on Mitsubishi K3 diesel engines: K3A (TU1400/TU1401, 776cc), K3B (TU1500/TU1501, 849cc) and K3C (TU1600/TU1601, 900cc) — engines that remained unchanged between both generations, which greatly simplifies parts selection. In this knowledge base you’ll find purchasing advice with indicative second-hand prices, an extensive comparison between the 00 and 01 series, complete technical specifications per model, maintenance schedules with adjustment values, engine oil and fluid recommendations, filter information, controls and cold starting, hydraulics and PTO, known faults from practical experience, and the matching original and compatible parts from the Snel Parts range.
