The Multiquip 21172 Throttle Cable is a genuine OEM Throttle Cable designed for Whiteman and International walk-behind power trowel models including the HDA-Series, J36-M30 Series, B46, BS90C, BH11C, BH90C, JS60C, JH90C, JH55C, J3036H55, BS46H11, BS46H90, JS36H90, JS36H55, CS24H55E, and B46S90. As a direct OEM replacement, it is manufactured to the same specifications as the original component, ensuring a consistent, accurate fit with no guesswork on installation.

Source it directly from DHS Equipment for confidence in part number accuracy and fitment.
Key Features
- Genuine OEM Construction — Manufactured to the original cable length, end-fitting type, and sheath specification — no calibration or adjustment needed after installation.
- Direct-Connect Replacement — Engineered to connect directly to the throttle lever and engine carburetor linkage on compatible Whiteman and International walk-behind trowel models without modification.
- Broad Walk-Behind Trowel Compatibility — Confirmed fitment across HDA-Series, J36-M30 Series, B46, BS90C, BH11C, BH90C, JS60C, JH90C, JH55C, J3036H55, BS46H11, BS46H90, JS36H90, JS36H55, CS24H55E, and B46S90 models.
- Smooth Throttle Response — A correctly functioning throttle cable maintains precise engine RPM control, allowing the operator to set and hold trowel blade speed accurately throughout a finishing pass.
- Prevents Loss of Engine Control — A frayed, kinked, or stretched throttle cable causes erratic RPM response or complete loss of throttle control — replacing it promptly restores safe, consistent operation.
The throttle cable is the mechanical link between the operator's throttle lever and the engine's carburetor or governor linkage. It transmits hand input directly into engine speed changes, giving the operator control over blade rotation speed and finishing pressure. When the cable stretches, frays, or seizes inside its sheath, throttle response becomes sluggish or unpredictable — the engine may not hold a set RPM, making it difficult to achieve a consistent finish on the concrete surface. Replacing a worn throttle cable restores direct, responsive engine control and is a routine part of keeping a walk-behind power trowel in proper working condition.
