  • Onezhets 320 base machine is purposed for replacement of TLT-100A-06 base machine.  It is equipped with a new cab, enforced frame, undercarriage of higher cross-country ability with wider track chains and planetary final reduction gears with drive sprockets of bigger diameter placed closer to the bearing surface. 
  • Improvement of the undercarriage allows increasing of the length and width of the tractor bearing surface which results in rapid increase of the tractor’s cross-country ability on grounds with low bearing capacity and in deep snow, the machine’s lateral stability is also increased. Wider track chain links minimize soil disturbance. Hydrostatic transmission (HST) consists of an adjustable pump of LINDE brand, mounted on the pump drive reducing gear by Stibel, and and ajustable motor LINDE mounted on the rear axle block. Application of reinforced frame increases reliability of the machine operation. Mean time to overhaul is 10 000 machine hours. The cab features one adjustable full-revolving seat, protection, vibration and noise insulation, system of micriclimate normalization, improved observability. The machine can be equipped with engines manufactured by Russian or foreign companies.
