The Wacker Neuson 5100039139 Short Thruhard Blade Mount is a genuine OEM component designed for the CT36 series walk-behind concrete power trowels. This OEM part is sourced directly through Wacker Neuson's authorized supply chain, ensuring it meets the exact material and dimensional specifications required for safe, consistent blade operation. Fitment covers the full CT36 family, including the CT36-5A, CT36-6, CT36-8A, CT36-9, CT36-400E, CT36-9-V, CT36-8A-V, CT36-X, and CT36-X-C models. Replacing a worn or damaged blade mount with the correct 5100039139 part restores proper blade seating and helps maintain finishing quality on every pour.
Key Features
- Thruhard Material Grade — The thruhard construction of this blade mount provides the hardness and wear resistance needed to withstand the repetitive stress and abrasive contact of concrete finishing work.
- Direct Blade Interface Fit — Engineered to the exact bolt pattern and seating geometry of the CT36 rotor arms, so the blade locks in at the correct angle without shimming or rework.
- Broad CT36 Family Coverage — Confirmed fitment across CT36-5A, CT36-6, CT36-8A, CT36-8A-V, CT36-9, CT36-9-V, CT36-400E, CT36-X, and CT36-X-C variants, including adjustable-handle configurations.
- Consistent Blade Pressure — A correctly seated blade mount keeps finishing blades tracking flat across the slab surface, preventing uneven float patterns or blade chatter that compromise the finished floor.
- Safety-Critical Blade Retention — A cracked or worn blade mount can allow blades to shift or detach at speed, creating a serious hazard for the operator and nearby workers. Replacing this part on schedule is a direct safety measure.
- Genuine OEM Specification — Supplied as a genuine Wacker Neuson OEM part, part number 5100039139 is manufactured to the same specification as the original, with no substitution of materials or tolerances.
The blade mount is the mechanical interface between the trowel's rotor arm and its finishing blade. It holds each blade at the correct pitch angle and locks it securely in place as the rotor spins at working speed. When a blade mount cracks, deforms, or wears through, blades can shift out of alignment or lose secure attachment altogether — producing uneven surface finish and creating a risk of blade ejection. Keeping this component in good condition is essential to both the quality of the finished concrete surface and the safe operation of the machine.
