The Multiquip 20678 Back Seatframe Panel is a genuine OEM component designed for HTX44 and STX55 series hydrostatic ride-on power trowels. As a direct OEM replacement, part 20678 is manufactured to the same specifications as the original, ensuring a correct, trouble-free installation on affected machines. This panel is confirmed compatible with HTX44K4, HTX44K5, HTX44Y4, HTX44Y5, STX55J6, and STX55Y6 models. Sourcing a genuine Multiquip part means you can trust the fit without guesswork or rework on the job.
Key Features
- Genuine OEM Construction — Manufactured to original structural specifications, delivering the same panel geometry and mounting interface as the factory-installed part.
- Direct Drop-In Replacement — Mounts to the existing seatframe hardware with no rework or modification to the surrounding structure.
- Broad HTX44 and STX55 Coverage — Compatible with HTX44K4, HTX44K5, HTX44Y4, HTX44Y5, STX55J6, and STX55Y6 hydrostatic ride-on trowel models.
- Operator Support Integrity — A properly fitted seatframe back panel keeps the operator seating structure rigid and correctly aligned, which is essential for sustained control during finishing passes.
- Operator Safety Relevance — The seatframe assembly is a structural component of the operator station; maintaining it in sound condition supports proper operator positioning and machine control.
The back seatframe panel forms the rear structural section of the operator seat assembly on Multiquip hydrostatic ride-on trowels. It provides the rigid backing that supports the seat cushion and keeps the operator correctly positioned while running the machine. When this panel is cracked, warped, or broken, the seat assembly loses structural integrity, compromising operator comfort and control during extended concrete finishing work. Replacing it with a genuine Multiquip 20678 panel restores the seat structure to its original condition.
