The Multiquip 12785 Spider Kit 4 Blade 1-1/4 Shaft is a genuine OEM component designed for HTN27K, HTN28K, and HHXDF4-DF5 Whiteman ride-on power trowels. As a direct factory replacement, this kit ensures the blade assembly interfaces correctly with the 1-1/4 inch shaft, maintaining the precise pitch control that ride-on trowels depend on for a quality concrete finish. Sourced directly from Multiquip, part 12785 meets the same specifications as the original component installed at the factory. If your current spider assembly shows wear, cracking, or blade play, this kit restores full trowel arm function and keeps your finishing pass consistent.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original design tolerances, ensuring correct blade seat geometry and shaft engagement on the 1-1/4 inch drive shaft.
- Direct Blade Assembly Replacement — Matches the 4-blade spider configuration exactly, allowing straightforward installation without reworking the trowel arm mounting points.
- Confirmed Fitment — Verified for HTN27K, HTN28K, and HHXDF4-DF5 Whiteman ride-on power trowels; always cross-reference your machine model before ordering.
- Consistent Pitch Transfer — A properly functioning spider kit translates handle input into uniform blade pitch across all four arms, directly affecting surface flatness and finish quality.
- Prevents Blade Wobble and Chatter — Worn spider components allow blade slop that causes uneven troweling pressure and surface defects; replacing this kit restores tight, controlled blade movement.
The spider kit is the central hub assembly that connects the four trowel blades to the main drive shaft on a ride-on power trowel. It transmits pitch adjustments from the operator controls outward to each blade arm simultaneously, so every blade changes angle in unison. When the spider wears or cracks, blades can develop independent play, leading to uneven finishing pressure, surface scuffing, and loss of pitch control — all of which compromise the quality of the finished concrete slab.
