  • Integrated the hydrostatic oil tank and implement hydraulic oil tank to improve filtratedprecision and cooling capability of hydraulic system, increasing reliability and reducingmaintenance cost
  • Maintenance costs are reduced by 60% when compared competitors with torque converter and transmission and rear axle
  • Counter rotation, power turn and infinitely variable speed save lots of time, increasing working efficiency

Engine

High power electronically controlled engine helps to increase SEM826D productivity by 15%.

There are three power modes:

a) Economy mode (242 hp) for fuel economy and light duty applications such as downhill material handling and surface leveling

 

b) Standard duty (270 hp) for general applications such as construction site and forestry

 

c) Full power mode (294 hp) for maximum productivity and moving large volumes of heavy material, including uphill
