The Honda 17850-VF9-B11 Throttle Lever Assembly is a genuine OEM component designed for HHE31 stick edgers and UMK422 and UMK431 trimmers. As a direct OEM replacement, this assembly is manufactured to Honda's original specifications, ensuring the lever action, pivot geometry, and cable engagement match what came on the machine from the factory. Confirm your model and serial number against the fitment table before ordering, as Honda supersedes parts at serial breaks and more than one variant may exist across production runs.
Key Features
- Genuine OEM Throttle Control — manufactured by Honda to match the original lever travel, detent feel, and cable pull distance, so throttle response is consistent from idle to full speed
- Direct OEM Replacement — replaces the original assembly on HHE31 stick edgers and UMK422 and UMK431 trimmers without adaptation
- Check Your Serial Number — Honda updates part numbers at production breaks, so verify your unit's serial number against the fitment table to confirm this is the correct assembly for your machine
- Restored Operator Control — a worn or damaged throttle lever can cause erratic engine speed or prevent the operator from reaching full power; this assembly restores crisp, direct throttle response
The Throttle Lever Assembly is the operator's primary interface for controlling engine speed on handheld outdoor power equipment. When the operator squeezes or moves the lever, it pulls the throttle cable, which opens the carburetor slide or butterfly valve and increases fuel and air delivery to the engine. A lever that is cracked, worn at the pivot, or no longer holds its position properly will make the machine difficult to control — causing it to bog under load, surge erratically, or fail to reach the power needed to cut cleanly. Replacing this assembly restores direct, predictable control over engine speed for the HHE31 stick edger and UMK422 and UMK431 trimmers.
