Key Features
- Genuine OEM Construction — Molded to Multiquip's original material and dimensional spec, so the knob seats and grips exactly as the machine was designed to operate.
- Direct-Replacement Hardware — Installs onto the existing control shaft or rod without modification, using the same mounting interface as the original knob.
- Broad Mixer Compatibility — Fits Whiteman WM45, WM63, WM70, WM90, and WM120 series; Essick EM70, EM90, EM120, EM12M, and PRO12 series; and MQ MC44, MC64, MC94, and MC12 series mixers.
- Operator Control Integrity — A worn, cracked, or missing mushroom knob makes throttle or clutch controls harder to operate accurately; this replacement restores confident, positive control for the operator.
- Verified Multiquip Part Number — Order with confidence using OEM part number 29174-001, confirmed across the full range of compatible Whiteman, Essick, and MQ mixer platforms.
The mushroom knob is a control hardware component mounted on an operator-facing lever, rod, or shaft — most commonly associated with throttle, clutch, or engagement controls on concrete and mortar mixers. Its distinctive domed profile gives the operator a secure, comfortable grip point for actuating the control with one hand, even while wearing gloves on an active jobsite. When the knob cracks, breaks off, or goes missing, the underlying shaft becomes difficult to grip and operate safely, making prompt replacement important for normal machine function.
