Belt Drive or Hydraulic Drive?
The SG-40 Series is available with two cutterwheel drive systems, allowing you to select the option that best matches your priorities.
Belt-Driven Cutterwheel
Ideal for operators looking for maximum cutting performance.
Advantages:
- Three-belt drive system
- Easily adjustable belts using convenient adjuster bolts
- Greater torque than hydraulic-drive models
- Approximately 12–14% lower purchase price than hydraulic motor models
Hydraulic Motor-Driven Cutterwheel
Designed for operators who prioritize reduced maintenance.
Advantages:
- Hydraulic motor directly drives the cutterwheel
- No belts or bearings to maintain
- Dual-purpose purgeable shaft seal helps reduce contamination and protects against damage from wire, cable, and string
- Simplified long-term maintenance
Hydraulic-drive models typically offer slightly less torque than belt-driven versions while providing a cleaner, lower-maintenance solution.

No two contractors work the same way. That’s why the SG-40 Series gives you the flexibility to choose the combination of drive system and undercarriage that best fits your business.
Whether your priority is maximum traction, easy maintenance, higher torque, or navigating tight access points, there’s an SG-40 configured to help you work more efficiently and get more done.
