Most gas trimmers use one of these:
- 10mm x 1.25 LH (left-hand thread)
- 8mm x 1.25 LH
- 3/8″-24 LH
Battery and homeowner electric models often use small arbor-bolt adapters.
2. Shaft Type
- Straight shaft models typically support all Weed Warrior heads.
- Curved shaft models may NOT support heavy-duty/brush heads.
3. Engine CC Rating
Brush-and-blade-compatible heads often require 25cc–30cc+ engines.
