SENIX High Wheel Gas Walk Behind Brush Cutter and String Trimmer, 22-Inch Swatch with .155-Inch Line, 160 cc 4-Cycle Engine, Steel Deck, 14" Rubber Wheels, Adjustable Height (STMG-L)

What It Is

This is the complete wheel and tire assembly for the SENIX High Wheel Gas Walk Behind Brush Cutter and String Trimmer (model STMG-L). It includes the 14-inch rubber wheels, steel deck, and mounting hardware—designed for tough brush clearing and trimming on uneven terrain.

Fitment & Compatibility

• Exact fit: SENIX STMG-L brush cutter/trimmer only. Not compatible with other SENIX models or other brands without modification.
• Check before buying: Measure your existing wheel diameter (must be 14 inches) and axle hole size (typically 5/8-inch on this model). Confirm your deck is steel and matches the 22-inch cutting swath. If you have a different SENIX model, verify part numbers via the owner’s manual or SENIX support.
• OEM vs aftermarket: This is OEM SENIX. Aftermarket 14-inch wheels may fit but often require different bearings or spacers—stick with OEM for guaranteed fit.

Key Things to Know

• Quality: Rubber wheels are durable and provide good traction on grass, dirt, and light brush. The steel deck is heavy-duty but adds weight—expect the unit to be around 50 lbs.
• Installation: Direct swap. Remove the old wheel, slide the new one onto the axle, and secure with the existing cotter pin or clip. No special tools needed.
• Common gotcha: The axle nut can rust or seize—apply penetrating oil (like WD-40) before removal. Also, check that the wheel hub is centered; off-center wheels cause wobbling and uneven cut.
• Not for zero-turn or riding mowers: This is strictly for walk-behind SENIX trimmers/brush cutters.

Should You Buy It

Buy this if you own a SENIX STMG-L and your original wheels are worn, cracked, or have lost tread. It’s a direct, no-hassle replacement that restores traction and stability on rough ground. Skip it if you have a different brand or model—you’ll need to measure carefully or contact SENIX for the correct part.
