Multiquip 21318 Frame W/A Main HTN Kohler Complete

The Multiquip 21318 Frame W/A Main HTN Kohler Complete is a genuine OEM welded frame assembly designed for HTN27K and HTN28K mechanical ride-on power trowels. As a direct Multiquip OEM component, part 21318 is manufactured to the same specifications as the original unit, ensuring a consistent fit within the HTN series trowel chassis. This assembly is confirmed compatible with both the HTN27K and HTN28K Kohler-powered models, making it the correct choice when the main frame requires replacement due to structural wear, damage, or a complete machine rebuild.

Key Features

• Genuine OEM Structural Integrity — Produced to Multiquip's original weld and fabrication standards, so the frame geometry matches the HTN series chassis precisely without rework.
• Complete Welded Assembly — Supplied as a fully welded unit, eliminating the need to source or fabricate individual frame components separately.
• HTN Series Kohler Compatibility — Engineered specifically for HTN27K and HTN28K Kohler-powered mechanical ride-on trowels; use model codes to confirm your machine before ordering.
• Foundation for Drivetrain and Blade Performance — A sound main frame keeps the trowel's engine, gearbox, and spider assembly in proper alignment, directly affecting blade pitch consistency and finish quality.
• Rebuild-Ready Component — Ideal for full machine rebuilds or major overhaul jobs where the main frame is beyond repair, restoring the trowel to operational condition with an OEM-grade foundation.

The main frame welded assembly is the structural backbone of the HTN series mechanical ride-on power trowel. It supports the engine, transmission, and finishing blade spider, holding every drivetrain component in the correct positional relationship. When the main frame is cracked, bent, or otherwise compromised, the entire machine suffers — blade alignment drifts, vibration increases, and consistent surface finishing becomes impossible. Replacing the frame with a correct OEM assembly restores the structural baseline the rest of the machine depends on.
