Key Features

• Genuine OEM Construction — Manufactured to Multiquip's original design tolerances, ensuring the pitch control mechanism operates with the same range of motion and engagement as the factory-installed component.
• Direct-Fit Replacement — Installs into the blade pitch assembly without modification, maintaining the correct geometry between the control linkage and blade holders.
• Broad Trowel Compatibility — Fits J36, JA-Series, CA4HC, B46, BS46, JS36, PRO36, PRO46, and HDA heavy-duty series walk-behind trowels, covering both 36" and 46" rotor diameters.
• Precise Blade Angle Control — A correctly functioning pitch control block allows operators to accurately adjust blade pitch angle throughout the finishing cycle, from floating through final burnishing passes.
• Maintains Control Linkage Integrity — Worn or damaged pitch control blocks cause inconsistent blade angle response, leading to uneven surface finish and loss of operator control — replacing promptly restores predictable trowel handling.

The pitch control block is a core mechanical component within the blade pitch adjustment system of a walk-behind power trowel. It acts as the interface between the operator's pitch control handle and the individual blade holders, translating handle input into consistent blade angle changes across all rotor arms. When the pitch control block wears, cracks, or becomes damaged, the connection between the control mechanism and the blades becomes imprecise, resulting in uneven blade pitch, inconsistent concrete finishing, and reduced operator feedback. Replacing a worn 20280 Pitch Control Block restores full, accurate control over blade angle — which is essential for achieving a quality finish at every stage of the concrete curing process.
