The Wacker Neuson Tow Valve is a genuine OEM component designed for the RD12-90 and RD12A-90 series tandem rollers, including solid ROPS and foldable ROPS configurations. Sourced directly from Wacker Neuson, this part meets the same specifications as the original installed at the factory, ensuring proper hydraulic function and fitment across the full RD12 roller lineup. Confirmed compatibility spans five distinct RD12-90 and RD12A-90 machine configurations, so you can order with confidence that is the correct part for your machine.
Key Features
- Genuine OEM Hydraulic Integrity — Built to Wacker Neuson's original valve specifications, ensuring correct pressure response and flow control for the tow circuit.
- Direct Drop-In Replacement — Engineered to the same port configuration and mounting interface as the original, allowing straightforward installation without reworking hydraulic lines.
- Broad RD12 Series Fitment — Compatible with RD12-90 and RD12A-90 tandem rollers across solid ROPS and foldable ROPS variants, covering a wide range of machine configurations.
- Maintains Proper Tow Capability — A functioning tow valve allows the roller to be safely moved without the engine running; a failed or bypassed valve can compromise machine mobility and site safety.
- Hydraulic System Safety — Correct valve operation is essential for controlled towing; using an OEM-spec replacement helps preserve safe, predictable hydraulic behavior during machine relocation.
The tow valve on a tandem roller is a hydraulic component that allows the machine's drive system to be disengaged so the roller can be towed or moved freely without engine power. It works by relieving hydraulic pressure within the drive circuit, preventing the hydrostatic transmission from locking up the drums during towing. When this valve fails or becomes stuck, the machine may resist being moved, or in some cases, the drive system may not engage correctly during normal operation — making prompt replacement essential for both safe towing and reliable day-to-day compaction work.
