What materials can the MudMixer Evolution mix?
The MudMixer Evolution mixes concrete, mortar, grout, stucco, pool-crete, and other compatible bagged materials up to 80 lbs. Its continuous-feed design ensures consistent, uninterrupted mixing.
Is the MudMixer Evolution electric powered?
Yes. It operates on standard 120V power and uses a precision water-dial system with dual spray nozzles for accurate mix consistency.
Operation & Setup
How much assembly is required?
Assembly is minimal. Attach the wheels, handle, and mixing chute, connect a standard garden hose, and install the Hopper and Chute Extensions using the included hardware. Most users are mixing within 15–20 minutes of unboxing.
How fast can the MudMixer Evolution produce mix?
The Evolution can process 45+ 80 lb bags per hour depending on water ratio and material type. Continuous-feed mixing means no stopping between batches.
Can I adjust the water flow?
Yes. The adjustable water dial and dual spray nozzles let you fine-tune water flow for ideal mix consistency across all material types.
How do the Hopper and Chute Extensions help on the job?
The Hopper Extension increases your loading capacity up to 300 lbs of dry mix, reducing downtime. The Chute Extension adds extended reach for cleaner pours into forms, slabs, or wheelbarrows.
Cleaning & Maintenance
How do I clean the MudMixer Evolution after use?
Run clean water through the system for 2–3 minutes immediately after mixing. Power off the unit, remove the auger, and rinse thoroughly. Do not allow material to harden inside the hopper or chute.
Does the mixer need regular lubrication?
Lubricate wheel axles and pivot points as recommended in the maintenance guide. Avoid using grease inside the hopper or chute where it could contaminate the mix.
What should I do if the auger becomes jammed?
Turn off and unplug the mixer before attempting to clear the jam. Remove the auger and clean the obstruction manually. Never reach inside the hopper or chute while the unit is powered.
