The Multiquip 29173-001 Stop Button With Gas Engine is a genuine OEM component designed for MQ, Whiteman, and Essick concrete and mortar mixer models.

Compatible models include MC94SK, MC94PK, MC64SK, MC64PK, WM45HE, WM45HCE, WM90PLF, WM90SLF, WM70PLF, WM70SLF, WM63H8, WM63H5, WM63E, WM120SH, WM120PH, EM120, EM90SLF, EM70SLF, PRO20, PRO12, and related series — sourced and sold by DHS Equipment as an authorized Multiquip parts distributor.
Key Features
- Genuine OEM Ignition Kill Circuit Integrity — Manufactured to the original electrical specification for the gas engine stop circuit, ensuring the button grounds the ignition reliably on every press.
- Broad Mixer Family Coverage — Fits a wide range of MQ, Whiteman, and Essick gas-engine mixer models including MC, WM, and EM series units, making this a single-part solution across multiple mixer lines.
- Drop-In Replacement — Matches the original mounting configuration and wiring interface, allowing the button to seat and connect without additional hardware or modification.
- Restored Operator Control — A worn or failed stop button can prevent the engine from shutting down on command; replacing it with part 29173-001 restores full, immediate operator control over the engine kill function.
- Critical Safety Function — The engine stop button is a primary safety control on any gas-powered mixer; using a genuine OEM part ensures the circuit performs correctly under daily jobsite use.
The stop button on a gas-engine mixer is wired into the ignition kill circuit, grounding the ignition system when pressed to shut the engine down quickly and safely. It is one of the most frequently operated controls on the machine, and a worn contact, cracked housing, or broken spring can leave the engine unable to be stopped by the operator. Replacing a failed stop button with the correct OEM part restores the safety shut-off function and keeps the mixer operating as intended.
