Buying Guide: Key Considerations
- Tractor compatibility: Confirm Category 1 3-point hitch compatibility and PTO shaft type (6-spline) for all choices.
- Cutting depth: Most models grind 6″ below ground; consider your site prep needs for final grading or sod installation.
- Flywheel and teeth: A 24″ flywheel with 34 carbide teeth is standard for steady grinding; teeth wear affects performance and replacement costs.
