Watch the company's walk-around below.
An Ergopower transmission and torque converter provide automatic shifting, and a 100-percent automatic differential lock combines with automatic no-spin power splitting to instantly transfer torque from a slipping tire to one with more traction. Creep mode engages just the front wheels, and the grader can move at extremely slow speeds.
Load-sensing hydraulics include a direct-activated axial piston pump that delivers only the required hydraulic pressure. Control valves provide pressure compensation, which allows the moldboard to lifted or lowered in parallel. Direct-mounted hydraulic controls increase lever rigidity and reduce play in the system.
Moldboards are high-carbon steel, and a new mount and slide system minimizes play and has fewer grease points than predecessor models.
