Multiquip 11787 Spider Plate Kit

The Multiquip 11787 Spider Plate Kit is a genuine OEM Spider Plate Kit designed for HTN series Whiteman ride-on power trowels and HDA series Whiteman walk-behind power trowels. As a direct OEM replacement, this kit is sourced and verified to meet the original manufacturer's specifications, giving you confidence that the part will install and perform exactly as intended. Compatible with HTN Kohler, Onan, and Honda engine configurations as well as the HDA series walk-behind units, this kit covers a broad range of Whiteman trowel applications. Sourced through DHS Equipment, an authorized Multiquip parts distributor, the 11787 is the correct-specification choice for restoring your trowel's blade pitch control system.

Key Features

• Genuine OEM Construction: — Manufactured to Multiquip's original design tolerances, ensuring the spider plate geometry delivers accurate blade pitch adjustment across the full range of trowel operation.
• Drop-In Fitment: — Engineered to match the original mounting points and hardware interfaces on HTN and HDA series trowels, so installation follows the standard service procedure without modification.
• Broad Trowel Compatibility: — Fits HTN series ride-on trowels (Kohler, Onan, and Honda engine variants) and HDA series walk-behind trowels, making this kit a versatile stocking part for mixed Whiteman trowel fleets.
• Restored Blade Pitch Control: — A worn or damaged spider plate causes uneven blade pitch, leading to inconsistent surface finish and operator difficulty. Replacing this kit restores precise, uniform blade angle across all finishing blades.
• Complete Kit Format: — Supplied as a full kit rather than individual components, so you have everything needed to complete the repair in a single order.

The spider plate is the central mechanical hub of a power trowel's pitch-control assembly. It connects the gearbox output to the individual finishing blades, translating the operator's pitch input into synchronized blade angle changes across all arms. When the spider plate or its associated components wear or crack, blade pitch becomes uneven or unresponsive, which directly degrades the quality of the concrete surface finish and increases operator effort. Replacing the spider plate kit as a complete assembly restores full, consistent control over blade angle and helps the trowel perform to its designed finishing capability.
