3-1/2 cu. ft. with 1/2 Horse Power Electric Motor Wheelbarrow Mixer
This mixer is OK for occasional home use, Not up to constant commercial usage. I have mixed about 35 60# bags so far.
- Reasonably well made for occasional home projects.
- I like the wheelbarrow design, easy to pour into a trough and easy to move about.
- The motor belt and idler cover simply does not fit and does not work. Period. The six bolts that fasten the drive gear to the drum hit the cover six times per revolutiion and would quickly destroy the cover. I am an engineer and very expert at things mechanical.. trust me, no amt of adjusting is going to make this work. its a joke. I decided that it would be too hard to adjust the belt tension occasionally with it on so decided it would be simply easier to forget the cover.
- the larger drum gear cover also has problems and like the belt cover you'll be happier just shelving the safety covers and forgetting them. Mind you I accept no responsibilty for this advice. You are on your own. Greasing the gear and aligning the idler gear to drum gear mesh and angle would require constant removal.
- drum design allows a lot of unmixed material to accumulate at the bottom abd drum vanes. requires stopping mixer and manually scraping the unmixed material into the batch.
- I do not expect long life from the drums plastic sleeve bearings. YOU MUST ZIRK GREASE EACH USE !!

Rated 4.0 out of 5.0 by Wally Mixed feelings about mixer - overall good.
I have mixed impressions after assembling and using the product. There are a couple of annoying things about the way it is made, but overall it is a nice machine to use.
Assembly took a couple of hours and was uneventful with one exception: belt tensioning. I grew up on a farm, worked construction while going to college, and am a degreed manufacturing engineer, so I have some perspective on this. Took an hour just to get the belt aligned and tensioned. I had to mess with four bolts in slots that run one way in the motor mount, and at right angles to those slots in the frame. The same four bolts hold alignment and tension. If I could make one improvement, it would be to have one set of bolts hold alignment, and a separate set to hold tension, so we could set alignment, and then adjust tension.
Setting gear engagement was a little sloppy. There were no proper instructions. If you don't know how gears are supposed to engage, it would be easy to mess up.
Other than that, assembly was quick and painless, though instructions could be better at every step.
The bearings are polymer bearings, plastic sleeves that get greased. Plastic bearings can be just fine if kept clean and lubed; time will tell how these hold up. So far, no complaints about the bearings. The grease fittings are easy to find and easy to get at with a grease gun.
Tires are standard pneumatic wheel barrow tires. They are fine, but I think I would prefer not to have to worry about air in the tires.
In use, I find that the moulded-in mixing paddles make cleaning very, very easy. I did not even have to use a brush, but simply hosed it out clean. Mixing was good, as long as the mix is wet. I was trying for a stiffer mix, and I found that if the mix is not just a LITTLE looser than optimum for high strength, it will roll around in the middle and not mix properly. Most concrete workers like the mix a little loose, so it is alright. Keep the mix just a tad wet, and it mixes well.
Handling is easy, even with a full 160-lb load of concrete. I have to be careful after decades of abusing my back, but I had no trouble moving and dumping loads where I needed. If dumping higher than ground level, it might be difficult to empty it. For walks and patios, it will be fine. If you wanted to dump more than 8-10 inches high, you would need a ramp. I had no trouble at all dumping at ground level.
It is a nice height for loading.
The pushbutton on-off switch is very low and hard to see, but works OK by feel.
The handles slide in, making it smaller for storage.
One concern I have is that the motor has no overload protection. If overloaded or run with too light gage extension cord for too long, it could simply burn out. Not a problem so far, since it seems to have plenty of power, even with a full load of 160 lb. I used 12 gage 50ft cord with GFCI; I highly reccommend using GFCI when working around water and electricity. GFCI costs just a little more, and is literally a life saver.
I have not tested endurance; I just did a two-hour job with it. Overall, I like this machine for home use. It is not easy to assemble, but easy to use, easy to clean, and did not falter. It did the job well.
