The Multiquip 21631 Steering Handle Boot is a genuine OEM replacement built for STX and HTX series hydrostatic ride-on trowels, including the HTX44K4, HTX44Y4, STX55Y6, STX6H, LD60, and related models. As an authorized Multiquip OEM part, the 21631 is manufactured to the same specification as the original component, ensuring a direct fit without modification. This boot is a service-grade component designated for the STX and HTX platform and is compatible across a wide range of hydrostatic and heavy-duty ride-on trowel models. If your machine shows a torn, cracked, or missing handle boot, part number 21631 is the correct OEM replacement.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original material and dimensional specification for the STX/HTX steering handle assembly, not a generic substitute.
- Direct-Fit Replacement — Designed to seat and secure exactly as the original boot, requiring no trimming or adaptation during installation.
- Broad STX/HTX Compatibility — Fits HTX44K4, HTX44K5, HTX44Y4, HTX44Y5, STX55J6, STX55Y6, STX6H, STXDF, LD60, LD6/LD6SL, and additional hydrostatic ride-on trowel models.
- Handle Protection — Seals the steering handle pivot area against concrete dust, moisture, and debris — contaminants that accelerate wear on internal handle components.
- Operator Safety Relevance — A deteriorated or missing handle boot can allow contamination into the steering control mechanism; replacing it promptly helps maintain predictable steering response on the trowel deck.
The steering handle boot on a ride-on trowel serves as a protective seal where the steering handle meets the machine's control housing. It keeps abrasive concrete dust and moisture from working into the pivot point and underlying components, which can cause premature wear and stiff or unpredictable steering over time. When the boot cracks, tears, or separates, the handle internals become exposed to the harsh jobsite environment — replacing it with the correct OEM part restores that protection and helps maintain consistent, responsive steering control.
