Frequently Asked Questions

Q: How do I know if this 26mm gear head fits my brush cutter or trimmer?

A: This replacement gearbox is designed for machines with a 26mm (1-inch) drive shaft diameter. Check your trimmer or brush cutter's manual or measure the existing gearbox shaft to confirm compatibility before ordering. You can also select either the 7-tooth or 9-tooth version to match your original unit.

Q: What is the difference between the 7-tooth and 9-tooth gearbox options?

A: The tooth count determines the gear ratio and torque output. A 7-tooth gear head typically provides higher speed, while a 9-tooth gear head offers more torque for tougher cutting tasks. Match the tooth count to your original gearbox for the best performance.

Q: Is this gearbox easy to install at home?

A: Yes — this is designed as a direct replacement part. Most users with basic mechanical knowledge and standard hand tools can complete the swap in minutes. Always disconnect your trimmer's power source before beginning any maintenance or part replacement.
