Key Features
- Genuine Honda OEM — manufactured to the exact specification of the original, ensuring the seat assembly fits and functions as Honda intended on your tractor
- Broad Tractor Fitment — designed for Honda H5013, H5518, H6522, HT3810, HT3813, HT4213, and RT5000 multi-purpose and lawn tractors, including the complete RT5000 and H65-series lineup
- Direct Replacement — replaces the original upper seat base with no adaptation needed, restoring the seat mounting structure to its as-built condition
- Serial Number Verification Recommended — Honda supersedes seat components at production breaks; check your tractor's serial number against the fitment table to confirm you have the right revision
The Upper Seat Base is the structural foundation of the operator seat mounting assembly on Honda tractors. It supports and positions the seat above the frame, providing the stable platform that the seat cushion and adjustment hardware attach to. When this base cracks, breaks, or deteriorates, the seat becomes unstable and loose, compromising operator comfort and control during use. Replacing a worn or damaged base restores proper seat support and keeps the operator correctly positioned at the controls.
