Multiquip 21211 Spider Kit 5 Blade Tapered HTH/HTX

The Multiquip 21211 Spider Kit 5 Blade Tapered HTH/HTX is a genuine OEM spider assembly designed for HTX44K4 and HTX44K5 hydrostatic ride-on power trowels. This kit delivers a direct-fit blade mounting solution engineered to Multiquip's original specifications, ensuring the blade arms seat and rotate exactly as intended. Sourced directly from Multiquip, part 21211 is the correct OEM replacement for worn or damaged spider assemblies on these machines. If you are maintaining or overhauling a HTX44K4 or HTX44K5 trowel, this is the part your machine was built with.

Key Features

• Genuine OEM Construction — Manufactured to the same tolerances as the original spider assembly, ensuring consistent blade arm engagement and rotation geometry across all five blades.
• Tapered 5-Blade Configuration — The tapered interface design provides secure, repeatable blade arm seating, minimizing blade slop and maintaining even float pressure across the trowel pan.
• Confirmed HTX Series Fitment — Verified for use on HTX44K4 and HTX44K5 hydrostatic ride-on power trowels; verify your model code before ordering.
• Consistent Finish Quality — A properly functioning spider assembly keeps all five blades tracking at the same pitch angle, which directly affects surface finish consistency on flatwork concrete.
• Safety-Critical Blade Control — The spider is the central connection point between the gearbox output and the trowel blades; a worn or cracked spider can cause erratic blade behavior and loss of operator control on a ride-on machine.

The spider assembly is the hub component that connects the trowel's drive shaft to the individual blade arms on a ride-on power trowel. It transmits rotational force from the gearbox to each of the five blades while allowing the pitch of the blades to be adjusted collectively. When the spider wears, cracks, or the tapered interfaces become damaged, blade arm movement becomes uneven or sloppy, leading to inconsistent concrete surface finishing and potential safety concerns during operation. Replacing the spider with a correctly spec'd OEM unit like the Multiquip 21211 restores precise blade control and keeps the trowel performing as designed.
