GR2405 Motor Grader

1.Using load sensinghydraulic system, the control force is small, the steering feel is good, andthe micro-motion control can be realized;
2.Using engine variablepower control technology to save energy;
3.Using intelligent fancontrol technology, the fan speed can be changed according to the systemtemperature monitored in real time, with low energy consumption and low noise;
4.Increased cab, largespace inside the cab;
5.The use of anintegral angular positioner, high-strength slewing bearing and overloadprotection worm gear box, the working device is more reliable;
6.Using torqueconverter lock-up technology, the transmission efficiency is higher.
