Honda 17852-VH8-641 Throttle Lock Lever (Yellow)

The Honda 17852-VH8-641 Throttle Lock Lever (Yellow) is a genuine OEM replacement designed for HHT25, HHT31, and HHT35 trimmers. As a direct Honda OEM component, this lever is manufactured to the same specification as the original, ensuring the throttle lock mechanism operates exactly as intended on your trimmer. Honda supersedes parts at serial number breaks, so confirm your trimmer's serial number against the fitment table before ordering to make sure part number 17852-VH8-641 is the correct match for your unit.

Key Features

• Genuine Honda OEM — sourced directly from Honda, this replacement matches the original lever in fit, color, and function for the HHT25, HHT31, and HHT35 trimmer lineup.
• Color-Coded Yellow — the yellow color designation is a specific variant identifier; confirm this matches the lever on your trimmer before purchasing.
• Throttle Control Integrity — a worn or broken throttle lock lever makes it impossible to hold a consistent engine speed, forcing the operator to maintain constant manual pressure and reducing cutting control.
• Serial Number Verification Advised — Honda issues part updates at production serial breaks; check your trimmer's serial number against the compatibility table to confirm this is the correct lever for your machine.

The throttle lock lever allows the operator to hold the throttle at a set position without continuous hand pressure — a key control feature during extended trimming work. When this lever becomes cracked, broken, or stiff, maintaining steady engine speed requires constant manual effort, which increases operator fatigue and reduces cutting consistency. Replacing a damaged lever restores full throttle control and brings the trimmer back to its intended operating behavior.
