- Low rotation speed of the cutter drum and high installed power - minimum dust development
- Electronically controlled sump and shear movement - optimized cutting sequence and power utilization
- Radio remote control system for all functions, except for the bolter controls
- Low ground pressure of crawler tracks
- No movement of crawler tracks during sump process - no damage to floor in soft ground conditions
- Fully supported machine to give stability for cutting
- Fully automated greasing system for minimized service requirements
