The Multiquip 20180 Spider Assembly Left Hand 5 Blade is a genuine OEM component designed for the HTX44 series hydrostatic ride-on power trowels, including the HTX44Y4, HTX44Y5, HTX44K4, and HTX44K5. As a direct Multiquip OEM part, the 20180 is built to the same specifications as the original assembly, ensuring correct geometry and blade-arm engagement for the left-hand rotor. Confirm your model code against the fitment list before ordering, as spider assemblies are handed and rotor-position specific. DHS Equipment supplies this part direct, giving you confidence in part number accuracy and provenance.
Key Features
- Genuine OEM Construction: — Manufactured to Multiquip's original dimensional and material standards, maintaining correct blade-arm spacing and pivot tolerances critical to even blade pitch across the rotor.
- Left-Hand Rotor Specific: — Engineered for the left-hand rotor position on HTX44 series machines; installs directly to the existing drive hub without modification to mounting points or pitch control linkage.
- HTX44 Series Fitment: — Confirmed fitment for HTX44Y4, HTX44Y5, HTX44K4, and HTX44K5 hydrostatic ride-on trowels — covering both Yanmar and Kubota-powered variants in the HTX44 family.
- Consistent Blade Pitch Control: — A worn or damaged spider assembly causes uneven blade pitch across the rotor, leading to surface chatter, poor finish quality, and increased stress on the pitch control mechanism. Replacing with a correct OEM unit restores smooth, consistent pitch response.
- Operational Safety: — The spider assembly directly controls blade angle on a high-speed finishing machine; a failed or cracked unit can cause abrupt blade contact and loss of surface control, making timely replacement with a verified OEM part essential.
The spider assembly is the central hub component that connects the individual trowel blade arms to the rotor head and translates pitch-control inputs into blade angle adjustments. On HTX44 series machines, each rotor runs its own handed spider assembly — the left-hand unit governs blade pitch on the operator's left rotor. When the spider assembly wears, cracks, or loses its pivot points, blade pitch becomes inconsistent or unresponsive, resulting in uneven concrete finishing, rotor vibration, and accelerated wear on surrounding pitch-control hardware. Replacing a failing spider assembly promptly protects the pitch control mechanism and keeps the finishing deck operating at full capacity.
