The Honda 76120-V09-D01 Tension Arm A is a genuine OEM replacement designed for the HA4120 lawn tractor. As a direct Honda OEM component, this part is manufactured to the exact specifications of the original, ensuring a proper fit without guesswork or modification. Confirm your tractor's serial number against the fitment table before ordering, as Honda supersedes parts at specific serial breaks and the correct arm for your unit depends on its build range.
Key Features
- Genuine Honda OEM — sourced directly from Honda, this Tension Arm A is identical to the part your HA4120 left the factory with, so installation goes smoothly and the geometry stays true.
- Exact Fitment for the HA4120 — engineered specifically for the HA4120 lawn tractor; verify your serial number against the compatibility table to confirm this is the correct arm for your machine.
- Maintains Proper Belt Tension — a correctly functioning tension arm keeps consistent pressure on the drive belt; a worn or damaged arm allows belt slip, uneven cutting, and premature belt wear.
The Tension Arm A is a pivoting bracket within the belt drive system of the HA4120 lawn tractor. It holds the tensioner in position to keep the drive belt at the correct tightness throughout operation. When this arm bends, cracks, or wears at its pivot point, belt tension becomes inconsistent — leading to slipping, power loss to the blade deck or drive, and accelerated wear on the belt itself. Replacing a damaged arm restores consistent drive engagement and protects the surrounding components from secondary wear.
