As a direct Wacker Neuson OEM part, the is manufactured to the exact specifications of the original component, ensuring a proper connection between the light tower trailer and your tow vehicle. This adjustable ball coupler accommodates varying ball heights, making it a versatile and practical replacement for field use. Confirm your model number before ordering to ensure correct fitment across the LTN and LTV tower families.
Key Features
- Genuine OEM Coupler Integrity — Engineered to Wacker Neuson's original locking and load tolerances, so the coupler engages and releases the trailer ball the same way the original did from the factory.
- Adjustable Ball Height — The adjustable design accommodates different tow vehicle hitch heights, allowing proper tongue alignment without the need for a secondary adapter.
- Broad LTN and LTV Series Fitment — Verified for LTN6C, LTN6L, LTN6K-LT, LTN8K, LTV6K, LTV6L, and LTV8K light towers, covering both Tier 4F and standard tower configurations.
- Secure Towing Connection — A correctly functioning ball coupler keeps the light tower trailer locked to the tow vehicle during transport; a worn or faulty coupler risks trailer separation and road hazards.
- Towing Safety Compliance — Replacing a damaged or worn coupler with a genuine OEM assembly helps maintain the trailer's towing integrity and supports compliance with towing safety requirements on public roads and work sites.
The ball coupler is the primary mechanical link between a towable light tower and the tow vehicle's hitch ball. It latches over the ball, locks in place, and transfers the tongue load during transport, keeping the trailer tracking correctly behind the vehicle. An adjustable coupler allows the receiver height to be set to match the tow vehicle so the trailer rides level. When a coupler wears, corrodes, or the locking mechanism fails, the trailer can become difficult to attach securely or, in a worst case, detach while under tow — making timely replacement critical for safe equipment transport.
