The Honda 42910-960-000 Right Front Adjuster Arm is a genuine OEM replacement designed for the HR21 lawn mower. Sourced directly from Honda, this part matches the original in form and function, ensuring a straightforward swap with no guesswork. If your current adjuster arm is worn, bent, or broken, this is the correct Honda-spec component to restore your mower's cutting height adjustment on the right front wheel position.
Key Features
- Genuine Honda OEM — manufactured to Honda's original specifications, so the fit and action match what came on the HR21 from the factory.
- Cutting Height Restoration — a damaged or missing adjuster arm makes it impossible to set and hold the correct cutting height; this part restores full, positive height control at the right front wheel.
- HR21 Fitment — built specifically for the HR21 lawn mower; verify your unit's serial number against the fitment table to confirm this is the correct arm for your machine.
- Direct OEM Replacement — as a Honda-sourced part, it installs as a drop-in replacement with no reworking or adaptation needed to match the original mounting.
The right front adjuster arm is part of the cutting height adjustment system on the HR21 lawn mower. It connects the right front wheel to the mower deck and allows the operator to set the blade height by locking the arm into the desired position. When the arm is cracked, worn at its pivot points, or broken off entirely, the wheel can no longer hold a set height — causing an uneven cut and making the mower difficult to control across varying terrain. Replacing it with a genuine Honda part restores consistent, repeatable height adjustment and gets the mower cutting cleanly again.
