Multiquip 12185 Ring 6 Blade Assembly - OEM Replacement Part

This 6-blade ring assembly is a critical wear component for Multiquip STX-series ride-on power trowels, responsible for the finishing action that creates smooth, level concrete surfaces. The ring assembly houses the individual blades that contact the concrete during the troweling process and must maintain proper balance and structural integrity to ensure even finishing across the full trowel diameter.

During operation, the STX-series utilizes independent hydraulic drive motors for each spider assembly, with blade speed controlled via foot pedal from slow speed for initial finishing to maximum speed for final passes. Because the ring assembly is subject to constant rotational forces and concrete contact, regular inspection is essential. Uneven wear or damage to the ring can cause one spider to spin noticeably faster or slower than the other, resulting in difficult steering control and inconsistent finishing quality. Annual trowel speed checks are recommended to maintain optimal performance and identify when ring replacement is necessary.

Compatible with the following Multiquip models:

• STX55J6
• STX6H
