Multiquip 20460 Support Block - OEM Replacement Part for Walk-Behind Trowels

The support block provides critical structural support for the trowel assembly on HDA Series walk-behind trowels, maintaining proper alignment between the spider assembly and blade configuration during high-speed finishing operations. This component ensures stable blade positioning and reduces vibration transfer during concrete floating and finishing work.

Designed for use with HDA Series walk-behind trowels, which feature a 48-inch width and 75.2-inch length working area with a four-blade spider assembly configuration. The support block works in conjunction with the gearbox and vertical rotating shaft system to maintain proper blade angle and consistent surface contact during operation. This part is essential for maintaining the structural integrity of trowels used for both floating and finishing applications with combination (8-inch), float (8 or 10-inch), or finish (6-inch) blade configurations.
