Dyna Chute Solenoid - M721

Dyna Chute Solenoid - M721

This is a replacement 12-volt DC starter solenoid for the Monarch M-721 Dyna-Chute hydraulic power unit, which is used to control the discharge chute on concrete mixer trucks. The solenoid acts as a heavy-duty relay, taking a low-amperage signal from the start switch to connect the high-amperage current from the battery to the power unit's motor. This is a critical component for engaging the hydraulic system that operates the chute. It is a necessary replacement part for units with a failed or intermittently working start switch.

Key Features

• Direct replacement for the original start switch on M-721 power units
• Designed for 12V DC electrical systems
• Canister-type design for durability
• Enables remote electrical operation of the hydraulic pump motor

Fits These Mixers

This starter solenoid is specifically for the Monarch Hydraulics (now Bucher Hydraulics) M-721 Dyna-Chute hydraulic power unit. This power unit is widely used to control the discharge chutes on various models of cement delivery and ready-mix concrete trucks.
