Multiquip 12903 Control Assembly Left Side Riders - OEM Replacement Part

This left-side control assembly is the primary operator interface for ride-on power trowel machines, managing critical functions including throttle, blade pitch adjustment, and steering input for the left rotor system. Designed specifically for dual-rotor ride-on trowels, this control assembly integrates with the left-side gearbox and spider assembly to provide precise command over trowel operation during finishing work.

Mounted on the operator platform of ride-on trowels like the EHHNK5, this control assembly works in tandem with monitoring systems including the gearbox sight glass for oil level verification. The assembly is engineered to withstand the vibration and demands of commercial concrete finishing operations, where precision control is essential for achieving proper surface finish. Failure symptoms include unresponsive blade pitch control, difficulty steering the left rotor, or inconsistent throttle response affecting one side of the machine.

Compatible with the following Multiquip ride-on trowel models:

• EHHNK5
• HHN-34TVD
• HHNG4
