Key Features
- Genuine Honda OEM — sourced directly from Honda, this arm matches the original component your HR21 mower left the factory with, with no guesswork on fit or form.
- Correct Adjustment Geometry — as a Right Rear Adjusting Arm, this part maintains the proper cutting height and deck positioning that the HR21's adjustment mechanism depends on for consistent results.
- Check Your Serial Number — Honda supersedes parts at production breaks, so always cross-reference the serial number on your HR21 against the fitment table to confirm this is the correct arm for your specific unit.
The Right Rear Adjusting Arm is a structural component of the HR21 lawn mower's cutting height adjustment system. It works as part of the rear wheel height linkage, allowing the operator to raise or lower the rear of the cutting deck to the desired cutting height. When this arm is bent, cracked, or worn, the deck can sit unevenly or refuse to hold the selected height setting, leading to an uneven cut across the mowing pass.
