The Wacker Neuson 5100039138 is a genuine OEM Long Blade Mount Thruhard designed for the CT36 series walk-behind concrete power trowels. This includes the CT36-8A, CT36-8A-V, CT36-9, CT36-9-V, and CT36-400E models. As a direct OEM replacement, the 5100039138 is manufactured to the same specifications as the original component fitted at the factory, ensuring proper blade retention and consistent trowel performance across the full CT36 lineup. Keep a spare on hand and avoid unnecessary work stoppages during active concrete finishing operations.
Key Features
- Genuine OEM Blade Retention Integrity — Manufactured to exact OEM specifications, ensuring the blade mount maintains the correct clamping force and secure blade-to-spider arm engagement needed for smooth, even finishing passes.
- Thruhard Construction — The thruhard designation indicates hardened material throughout the mount body, providing enhanced wear resistance at the high-stress blade attachment point.
- Direct Fit for CT36 Series Trowels — Confirmed fitment for CT36-8A, CT36-8A-V, CT36-9, CT36-9-V, and CT36-400E walk-behind concrete power trowels with no rework or adaptation at installation.
- Consistent Blade Pitch and Overlap Control — A correctly functioning blade mount holds each finishing blade at the set pitch angle; a worn or loose mount causes uneven blade contact, chatter marks, and poor surface finish on the slab.
- Safety-Critical Fastening Point — The blade mount is the primary connection between the rotating spider arm and the finishing blade. A failed mount can allow a blade to shift or release during operation, making timely replacement an important operational safety consideration.
The blade mount is the mechanical interface that secures each finishing blade to the spider arm of the power trowel. It holds the blade at the correct pitch angle so the trowel can progressively work and densify the concrete surface during finishing passes. When a blade mount wears, cracks, or loosens, the blade loses consistent contact with the slab — resulting in surface defects, uneven finish quality, and increased stress on adjacent hardware. Replacing a worn mount promptly with a correct OEM part restores proper blade geometry and protects the integrity of the spider arm assembly.
