The Multiquip 20181 Spider Assembly 5 Blade RH is a genuine OEM component designed for HTX44 series hydrostatic ride-on power trowels, including the HTX44Y4, HTX44Y5, HTX44K4, and HTX44K5. As a direct OEM replacement, part 20181 is sourced from Multiquip to ensure it matches the original assembly configuration used on these machines at the time of manufacture. Please note that this part carries an NLA (No Longer Available) and OBS (Obsolete) designation, meaning it has been discontinued and available stock is limited — buyers should confirm availability before ordering. If you are servicing an HTX44 series trowel, securing this assembly while stock exists is strongly advised.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original design specifications, ensuring the spider arm geometry and blade attachment points match the factory assembly exactly.
- Right-Hand Configuration — The RH designation confirms this is the right-hand rotor spider assembly; correct handedness is critical for proper blade pitch and rotation on HTX44 trowels.
- 5-Blade Spider Design — Engineered for five-blade rotor setups, providing the blade count and arm spacing required for optimal surface coverage on HTX44 machines.
- Confirmed HTX44 Series Fitment — Verified for HTX44Y4, HTX44Y5, HTX44K4, and HTX44K5 hydrostatic ride-on trowels; always cross-reference your model code before ordering.
- Discontinued — Limited Availability — Officially NLA and OBS status means this is end-of-life stock; once supply is exhausted, no further units will be available through Multiquip's OEM supply chain.
The spider assembly is the central rotor hub that connects the trowel blades to the gearbox output on a ride-on power trowel. Each blade arm radiates from the spider hub, and the assembly controls the angle and rotation of the finishing blades across the concrete surface. A worn, cracked, or damaged spider assembly compromises blade pitch consistency, which directly affects the quality and smoothness of the finished concrete surface. On hydrostatic machines like the HTX44 series, where blade pitch is hydraulically adjusted, a structurally sound spider assembly is essential for precise blade response and uniform finishing passes.
