Multiquip 20628 W/A Frame - OEM Replacement Part for Ride-On Power Trowels

The W/A Frame is a critical structural component that serves as the main chassis assembly for the STX-series ride-on power trowel, providing the foundation that supports the hydraulic drive motors, operator controls, and blade assemblies during concrete finishing operations. This frame assembly ensures proper alignment and stability of the dual independent hydraulic drive motors that control each spider, which is essential for maintaining even trowel speed and responsive steering control during slab finishing work.

Because the STX-series operates with two hydraulic drive motors functioning independently of each other, the structural integrity of the frame is crucial for preventing speed variance between spiders and maintaining controllable steering. Multiquip recommends checking trowel speed at least once annually, and a damaged or worn frame assembly can contribute to difficulty controlling steering or noticeable speed differences between spiders. The frame must maintain precise tolerances to support the foot pedal blade speed control system and dual joystick steering mechanisms that operators rely on for controlled motions during finishing operations.

Compatible with the following Multiquip models:
