EGO Power+ 3-Teeth Metal Blade for Commerical String Trimmer STX3800 - ABB1203

What It Is

This is a 3-teeth metal blade designed for the EGO STX3800 commercial string trimmer. It replaces the standard string head for heavy-duty cutting of thick brush, blackberry vines, and saplings up to 1-inch diameter.

Fitment & Compatibility

• Exact fit: Only for EGO STX3800 commercial string trimmer. Not compatible with any other EGO trimmer model (e.g., ST1500, ST1623T).
• Mounting: Uses a 3-hole bolt pattern specific to the STX3800’s metal blade adapter. You must already have the metal blade adapter (sold separately, part #EAP3800) installed on the trimmer. This blade does not include the adapter.
• Measurements: Blade diameter is 10 inches, with a 1-inch arbor hole. Verify your trimmer’s guard has clearance for a 10-inch blade before mounting.
• OEM vs aftermarket: This is an OEM EGO part (ABB1203). Aftermarket blades may not match the hole pattern or balance.

Key Things to Know

• Installation difficulty: Moderate. You need to remove the string head, install the metal blade adapter, then bolt on the blade. Torque to 20 ft-lb; over-tightening can strip the adapter.
• Performance: Cuts thick material well, but dulls faster than steel blades on rocky soil. Plan to sharpen after 2-3 heavy uses.
• Safety: The trimmer guard must be in place. The blade can throw debris or kick back on hard objects. Use full eye and leg protection.
• Noise: Much louder than string. Ear protection is essential.

Should You Buy It

Buy this if you use the STX3800 professionally or for property maintenance and regularly need to clear thick brush, blackberries, or small woody growth. Skip it if you only trim grass or light weeds—string heads are quieter, safer, and cheaper to maintain.
