Key Features
- Genuine OEM Construction — Manufactured to the original design specification for the Yanmar55-equipped STX55 series, ensuring the throttle linkage geometry matches the engine and control system exactly.
- Direct Bolt-On Replacement — Mounts to the same attachment points as the original bracket, requiring no fabrication or modification to the throttle assembly.
- Confirmed STX55 Series Fitment — Verified for the STX55J6 and STX55Y6 hydrostatic ride-on trowels; always cross-reference part number 21744 before ordering.
- Throttle Control Integrity — A sound, correctly positioned throttle bracket maintains precise engine response across the full RPM range, which is critical for consistent blade speed and finish quality on the slab.
- OEM Part Number Traceability — Carries the original Multiquip part number 21744, making reordering and service recordkeeping straightforward for fleet maintenance.
The throttle bracket is the structural mount that positions and secures the throttle control linkage relative to the engine on the STX55 ride-on trowel. It holds the throttle cable or rod in the correct alignment so the operator's input translates accurately into engine speed changes. When the bracket is cracked, bent, or missing, the throttle linkage loses its reference point, causing inconsistent engine response, uncontrolled RPM variation, or a complete loss of throttle function — any of which will take the machine out of service until the bracket is replaced.
