Multiquip 12072 Spider Assembly 4 Blade R.S.

The Multiquip 12072 Spider Assembly 4 Blade R.S. is a genuine OEM component designed for HTN27K and HTN28K Whiteman ride-on power trowels. As a direct factory replacement, this assembly meets the original engineering specifications for these mechanical trowel models, ensuring correct blade geometry and consistent finishing performance across the full pitch range. Sourced directly from Multiquip, part number 12072 is the correct OEM choice for operators who need a dependable, spec-matched repair that restores the trowel to full working condition.

Key Features

• Genuine OEM Construction — Manufactured to Multiquip's original tolerances for the spider hub interface, ensuring proper blade seating and pitch actuation without slop or misalignment.
• Direct-Swap Replacement — Engineered to mount exactly as the original on HTN27K and HTN28K trowels, with matching bolt patterns and blade arm geometry for a clean installation.
• 4-Blade R.S. Configuration — Purpose-built for the 4-blade ride-on setup on these mechanical trowel models, maintaining the correct blade spacing and rotational balance required for a flat, consistent finish.
• Fitment Verified for HTN27K and HTN28K — Confirmed compatible with Whiteman HTN27K and HTN28K ride-on power trowels; always cross-reference part number 12072 before ordering.
• Finish Quality Depends on Spider Integrity — A worn or damaged spider assembly causes uneven blade pitch, chatter marks, and inconsistent surface finish; replacing it promptly restores smooth, uniform concrete finishing.

The spider assembly is the central hub component that connects the trowel's pitch control mechanism to the individual blade arms. It translates the operator's pitch input into coordinated blade angle changes across all four blades simultaneously, which is what allows the trowel to transition from floating to finishing passes. When the spider assembly wears or becomes damaged, blades can lose synchronized pitch control, leading to surface defects, increased operator effort, and accelerated wear on surrounding drive components.
