The Honda 23421-734-630 Countershaft First Gear (33T) is a genuine OEM replacement designed for FR600 and FR800 tillers. Sourced directly from Honda, this gear is manufactured to the exact tooth count and dimensional tolerances of the original part it replaces. Honda supersedes transmission components at serial breaks, so confirm your tiller's serial number against the fitment table before ordering to ensure this is the correct gear for your unit.
Key Features
- Genuine Honda OEM — an authentic Honda part carrying the correct 33-tooth specification, so mesh geometry and gear ratio are exactly as Honda engineered them for the FR600 and FR800 transmission.
- Direct Transmission Fit — this gear drops into the countershaft position as a direct replacement, preserving the drivetrain engagement characteristics Honda built into these tillers.
- Serial Number Verification Recommended — Honda revises drivetrain components across production runs; check your tiller's serial number against the compatibility table to confirm this is the right gear for your machine.
- Smooth Power Transfer — a worn or chipped first gear causes rough engagement, erratic tine speed, or loss of drive; replacing it restores clean, consistent power delivery to the tilling output.
The countershaft first gear is a core element of the tiller's transmission, transferring engine torque through the gearbox to drive the tines at the correct speed and force for soil cultivation. First gear carries the highest load of any drive ratio, making tooth integrity critical — worn or damaged teeth interrupt the power flow, causing slipping, noise, or complete loss of tine drive. Replacing a damaged gear with a correct-specification OEM part restores full drivetrain engagement and returns the tiller to its designed working performance.
