Robust Cooling System
Provides cool air intake to maximize fuel efficiency and minimize emissions. An on -demand variable speed fan draws ambient air from a separate compartment in front of the engine through the cooling package. The exhaust air exits from the front of the machine, maintaining a cool engine compartment.
Reversible Cooling Fan
The cooling fan is reversible and automatically performs periodic cycles in reverse to clean the heat exchanger by expelling accumulated dust. This allows the system to cool more efficiently, ensuring optimal engine performance.
Electronically Controlled All-wheel Drive
Hydrostatic drive system has four pumps and four motors that are electronically controlled for optimized traction in extreme conditions.
Four Propel Pumps, Four Drive Motors
Four propel pumps provide separate, dedicated flow to all four drive motors. Provides superior tractive effort in soft underfoot conditions.
Load Sensing System
Load sensing system controlled by the ECM, matches propel speed to load on the engine.
Two Speed Ranges
Two speed ranges allow the machine to operate at either maximum torque to propel the machine through the toughest conditions, or a faster speed for moving around the job site.
Infinitely Variable Machine Speeds
Infinitely variable machine speeds determined by the propel lever and speed control buttons on the keypad.

Two universal rotors for different tasks.
Universal Rotor 41 cm (16") for Asphalt
Designed to produce maximum breakout force, the Universal Rotor 41 cm (16") performs well in severe asphalt cuts. It also cuts existing soil cement.
Universal Rotor 46 cm (18") for Soil
The Universal Rotor 46 cm (18") is designed to provide maximum mixing depth and has lower breakout force compared to the Universal Rotor 41 cm (16"). This rotor meets European 45 cm mixing depth requirements while providing the highest level of material pulverization and gradation.
Designed primarily for soil stabilization applications in cohesive soils. Designed for deep-cut soil mixing where pulverization and gradation is of lesser importance than higher working speeds. Performs well in cohesive soils and has a secondary application of surface mining for non-engineered substances such as coal, shale, or limestone.
Designed primarily for soil stabilization applications in semi-cohesive or granular soils. An ideal choice for mixing additives with semi-cohesive or granular materials where soil gradation is critical. Also can perform light reclamation applications where the asphalt layer is thin and deteriorated.
