Multiquip 11991-1 Trowel Blade Arm 22-1/2" Silver - OEM Replacement Part

This 22-1/2" trowel blade arm is a critical component of the blade pitch assembly on Multiquip ride-on power trowels, directly affecting blade angle and concrete finishing quality. The blade arm connects the pitch control system to the trowel blades, translating hydraulic stroke cylinder adjustments into precise blade angle changes during floating and finishing operations. Proper blade pitch calibration is essential for optimal concrete surface results—the STX6H technical manual specifies pitch sync calibration procedures using specialized gauge tools and CAN Gateway interface equipment to ensure synchronized blade operation across both trowel heads.

This silver finish blade arm maintains the structural integrity needed for consistent blade pitch control during high-speed troweling operations. Regular inspection of blade arms is recommended during routine maintenance intervals, particularly checking for wear at pivot points and connection interfaces that can affect pitch accuracy and synchronization between left and right trowel assemblies.

Compatible with the following Multiquip models:

• STX6H
• STXD6i
