AQBB Blade Kit Hardware for Echo SRM Trimmer – Adapter Plate Kit for SRM-225 & SRM Family

Overview

The AQBB Blade Kit Hardware is designed to work with Echo SRM trimmers, offering a practical upgrade path for a broad range of SRM models. This kit focuses on secure mounting and reliable compatibility across the SRM family (excluding high-torque versions). Use it as a way to refresh your trimmer’s blade hardware with a setup that emphasizes stability, alignment, and straightforward maintenance.

Key compatibility and fit

This kit targets select Echo SRM models, including 90051100010, C535000160, C535000150, and 6103150713. It is not suitable for high-torque 45 mm gearboxes that end with a T, so please verify your model before purchase. A quick check of the gear case assembly type and PTO shaft diameter helps ensure you select the right configuration for your machine. If your shaft size varies, specific steps and parts are provided to help you adapt the kit to your setup.

• Compatible models: 90051100010, C535000160, C535000150, 6103150713
• Vetted for all SRM series except high-torque T-endings
• Guidance to measure and match PTO shaft before purchasing

When the shaft measurements don’t match stock configurations, guidance is included for selecting the correct upper fixing plate or shaft collar to achieve a proper fit. The notes describe how a 32 mm shaft may require the short-connected upper fixing plate (y) and how a 42 mm shaft may need a shaft collar (z) with the short-necked plate to align correctly. This approach aims to help you avoid misalignment and ensure the kit sits firmly during operation.

Who this is for and use scenarios
