Key Features
- Genuine OEM Construction — Manufactured to the same tolerances and material specifications as the original Plate Spider, ensuring correct load distribution across the trowel blade assembly.
- Direct-Mount Replacement — Connects to the trowel head assembly using the original mounting configuration, allowing a straightforward swap with no adaptation needed.
- HTX44 Series Fitment — Confirmed for HTX44K5, HTX44Y4, HTX44Y5, and HTX44K4 hydrostatic ride-on power trowels.
- Blade Pitch Integrity — A correctly functioning Plate Spider maintains even blade pitch adjustment across all trowel arms; a worn or cracked spider causes uneven finishing and accelerated blade wear.
- Verified Part Number — Order 21751-001 with confidence — this is the exact Multiquip part number for this application, eliminating the guesswork of cross-referencing.
The Plate Spider sits at the center of the trowel head assembly and serves as the mechanical hub that connects the rotating trowel arms to the pitch-adjustment mechanism. It transfers the blade angle changes commanded by the operator evenly across all finishing blades, which is essential for producing a flat, consistent concrete surface. When the Plate Spider wears, cracks, or fails, blade pitch becomes uneven or unresponsive, leading to inconsistent finishing results and potential damage to surrounding trowel components.
