MudMixer and RYOBI cement mixers are constantly compared, usually on price alone. However, price is the least useful way to look at them.
These mixers are not the same kind of machine at two quality levels because they work in completely different ways.
How the RYOBI Works
The RYOBI RMX001 is a batch machine. The cycle goes like this.
- Load the drum with bags and water
- Let it turn until the mix comes together
- Tip the drum and dump into a wheelbarrow or the forms
- Reload and start over
RYOBI rates the drum at 5.0 cubic feet and lists a working capacity of 300 lbs, or 3 concrete bags at once. So every batch is three bags, then a full stop to dump and reload.
How the MudMixer Works
The MudMixer Evolution is a continuous mixer, meaning there is no batch. Bags go into the hopper, water meters in through a dial, a horizontal auger blends the material as it travels down the chute, and mixed concrete comes out without stopping. As long as somebody keeps feeding bags, material keeps coming.
MudMixer rates it at 45+ bags per hour, twice the output of a traditional drum mixer.
With the RYOBI, you mix three bags, stop, dump, reload. On the MudMixer, you never stop.

Where RYOBI is the Better Machine
- Price: It costs roughly a tenth of a MudMixer. That is not a small gap and it should not get waved off.
- Raw materials: A drum will mix sand, gravel, and cement in your own ratios. MudMixer is built around bagged mix. If you batch your own from bulk material, the drum is the correct tool.
- Custom mix designs: Same reason. If the recipe changes job to job, the drum gives you that control.
- Occasional use: For a few bags a few times a year, a drum mixer in the garage is the sensible buy.
Where the MudMixer Wins
It takes a man off the mixer
A drum mixer usually takes two or more people to run at full speed. One holds and cuts bags, one handles water and the dump. That second body is a hidden cost of a cheaper machine.
MudMixer is a one-person operation with a design to back it up. Bags go down on the hopper deck, an integrated bag opener cuts them, and gravity feeds the auger. The only work is lifting the bag.
The contractor who ran both machines on the same pour said it plainly afterward.
"I could have done that pad by myself with the MudMixer. It's a one-man operation. With the RYOBI it literally takes two, three guys."
On the drum side of that job, his helper was lifting 80 lb bags up to the drum over and over. "You got to hold the bag up while you mix that thing, when you can just drop the bag on a MudMixer, crack it, and go. It's not even close."
If an extra crew member costs $25/hour and the drum needs him on every pour, the price gap between the RYOBI and MudMixer closes faster than you think.
Every Bag Comes Out the Same
Batch mixing drifts. Dry pockets can show up in the drum, so water is added to chase them out, and now that batch is wetter than the one before. Do that ten times, and there are ten slightly different batches in one slab.
That is exactly what showed on the split pour. "That side's soaking wet. And this side's pretty consistent." The cause was straightforward.
Different consistency is a strength problem, not a looks problem. Water added past the mix design can lower the compressive strength. Over-wet concrete also scales at the surface and cracks more as it shrinks.
The MudMixer meters water through a fully adjustable dial, so every bag gets the same dose.
It Runs On Almost No Power
This one gets missed in most comparisons. The Evolution pulls 1.6 amps at 120 volts, off a 250 W motor.
That is less draw than a household box fan. A long extension cord runs it without voltage drop trouble. A small portable generator runs it on a site with no power at all. The motor is IP55 rated, so dust and water spray on a job site are accounted for.
A 1/2 HP motor turning a loaded drum pulls considerably more than 1.6 amps. On a stretched cord or a small generator, that difference shows up.
It Runs More Than Concrete
MudMixer lists concrete, mortar, stucco, grout, and poolkrete as materials the Evolution handles. That matters for anyone doing block work, pool decks, or stucco patches alongside flatwork. One machine covers all kinds of bagged materials on the truck.
Cleanup and Placement
The reinforced steel chute on the MudMixer has a control flap, so material goes where it is pointed. That means less wheelbarrow work and fewer trips between mixer and forms.
Cleanup runs about five minutes using the built-in hose and spray nozzle. A drum still has to be washed out, and on a multi-batch job the washing has to happen between stages, not just at the end.
MudMixer vs. RYOBI: What 80 Bags on One Slab Actually Showed
In this video, a crew drew a line down the middle of the pad and split it: MudMixer on one half, RYOBI on the other. Same mix, same weather, same day. The pad sat about 250 feet down a steep grade and took roughly 80 bags.
| MudMixer Side | RYOBI Side | |
|---|---|---|
| Bags placed | 50 | 40 |
| Thickness | 7 to 8 inches | About 4 inches |
| Time | 50 bags in about 45 minutes | Still going when the MudMixer half was done |
| Crew | One man, start to finish | Two, then three for the last few bags |
The bag count is the part worth reading twice. The MudMixer half was the thick corner, so it took 10 more bags of material, and it still finished first with one man on it. "This side was 10 bags deeper, which makes sense cuz this back corner was like 7 in."
The drum side did not finish under its own power. The crew stepped in for the last eight or nine bags because the operator's back was finished.

Drum Size is Not Output
A 5.0 cubic foot drum does not pour 5 cubic feet of concrete. That figure is total drum volume. A drum cannot be filled to the top or nothing tumbles, which is why RYOBI lists the real working capacity separately at 300 lbs, or 3 bags.
Three 80 lb bags is about 1.8 cubic feet of finished concrete, since an 80 lb bag yields roughly 0.6 cubic feet. So the actual batch out of a 5.0 cubic foot drum is closer to a third of the number on the box.
The MudMixer number looks smaller on paper and works the opposite way. The hopper holds 120 lbs standard, or 300 lbs with the extension. But the hopper is not a batch. It is a holding point for a machine that never stops running. Material goes in the top while mixed concrete is already coming out the chute, so hopper size does not cap output at all. It only changes how often somebody needs to drop in another bag.
That is why MudMixer publishes 45+ bags per hour instead of a capacity number. At 0.6 cubic feet per bag, that works out to about 27 cubic feet per hour, or right around a cubic yard.
One machine is rated by how much it holds. The other is rated by how much it puts down.
Compare mixers on bags per hour. Drum ratings will mislead you.
Cost and Break-Even Point
The gap between $3,695 and $349 only makes sense as a labor calculation, not a machine calculation.
The RYOBI is the right buy if:
- Pours happen a few times a year
- Jobs are fence posts, a very small pad, a walkway patch, or footings
- Raw sand and gravel get mixed instead of bagged material
The MudMixer is the right buy if:
- Jobs regularly run 30 bags or more in a session
- Labor is being paid, and a second man standing at a mixer is money off the job
- The finished surface is customer-facing and has to look uniform end to end
- Working alone is normal, or should be
- Bagged concrete, mortar, stucco, or grout is the standard material on site
- Sites often have no power, or power at the end of a long cord

MudMixer vs. RYOBI: The Short Version
The RYOBI RMX001 is a solid drum mixer at a low price with a good warranty, and it does what a drum mixer does. Three bags, dump, reload.
The MudMixer changes how the work happens. It removes the batch cycle, the bag lift, the second man, and holds the water dose steady across the entire pour.
For a homeowner setting posts on a weekend, the drum mixer can be the correct purchase. For a contractor running bagged material week after week on residential work, the math turns on labor hours, and it turns quickly.
