Multiquip 20639 Trunnion Pivot & Pitch Assembly - OEM Replacement Part

The trunnion pivot and pitch assembly controls the blade pitch angle on ride-on power trowels, allowing operators to adjust the aggressiveness of the finishing action during concrete surface operations. This critical steering and control component enables precise blade angle adjustments that directly affect the quality and smoothness of the finished concrete surface.

As part of the pitch control system on Multiquip ride-on trowels, this assembly experiences constant movement and mechanical stress during operation. Worn or damaged trunnion assemblies result in inconsistent blade pitch, poor finish quality, and difficulty controlling the machine. Regular inspection of pivot points and pitch mechanisms is essential for maintaining optimal trowel performance and operator control.

This assembly is designed for the following Multiquip ride-on trowel models:

• HTX-44K4
• HTXD6i
• STX55J6
• STXD6i
