PTO Concrete Mixer

Doug_Norman · Aug 25, 2006

I know there are other threads about PTO Concrete Mixers, and I've read those. I wanted to start a new thread, because I am in the market for one and thought maybe there is some new information out there.

I bought a mixer (French built) I am about to return because while it says it has a 1/3 yard capacity, that must be if you could tilt it all the way up and fill the drum completely full. When I tested it with water in the normal mixing position, it could only hold thirty some gallons - in the 4 to 5 cubic foot range. It also has a problem that the drive line to U-joint angle at the mixer is too tight in the mixing position. What I'd like to find out is:

1. Has anyone seen a PTO mixer that will truely mix 1/3 yard of concrete?
2. Any idea what they cost?
3. Has anyone seen one with a two-way hydraulic cylinder? Most seem to have a one-way to pull it up, and use gravity to dump - can't cycle when empty or nearly empty
4. Is anyone familiar with the Eagle EA320 Tractor Mounted Cement Mixer. It claims to mix 1/3 yard. I also wonder if it suffers from the tight drive line to U-joint angle.

Any dealers out there that sell a good mixer?

Thanks for any help,
Doug

If you searched for PTO mixer threads, you have prob already seen my
comments. I will try not to repeat myself (too much).

I have seen the Eagle and it looks similar to my Italian-made Mixer80. I
have not measured the volume of mine, but you have a very good point.
The actual total drum volume is way more than what you can actually
mix. Also, the most efficient mixing will happen with the drum nearly
horizontal.

It still amazes me that these units are sold with SA cylinders. DA is
clearly needed and I have tried it both ways.

AgriSupply sells the Mixer80 for $600 plus shipping. I have not seen a
bigger one for the 3pt. I think hydraulic is a good way to go, but you
are looking at 4x the cost. Hyd allows you to reverse the drum and
mount it on the your loader. No PTO hassles, either.

im confused...
1 cu yd = 12 cu ft
1/3 of 12 = 4
4 cu ft = 29.9 gallon

so how is 30 gallon mixxer not a 1/3 of a yard?

That's my better side. If I can fit MY head in one of these mixers,
it gotta be big......

.....and SCHMISM, a cy is 27cf, last time I checked......

I prefer hydraulic attachments, however, they are usually more expensive and the compact tractors typically don't have much implement hydraulics. Your L3130 only has about 8.0 GPM hydraulic flow.

The Kushlan unit seems pretty slick but it only mixes about 3.5 cu. ft. and it costs $1600. This price does not include hoses or other items you may need such as a 3rd SCV, diverter, etc. It runs at 0 to 30 GPM (5 to 30 RPM). I would have to guess that 8 GPM will get you 5 to 8 RPM. You would need to contact Kushlan to see what 8 GPM would get you with this unit.

Worksaver makes a heavier duty unit, the SS-585, which costs around $3600. It handles a 5 cu. ft. mix. It requires 8 GPM minimum, so your L3130 could probably handle it.

The other option would be to mount an electric unit on your loader, carry-all or to a sturdy trailer. You could then easily power it through a DC-AC inverter or a PTO Generator. I like this option because you can use the inverter/generator for other items such as pressure washers, air compressors, etc.

This Red Lion has a 5.5 Cu. Ft. capacity and only draws 7 Amps. It costs around $670 from Northern Tool. Since it is electric, it would be very easy to turn on and off with a nearby switch. You don't need to run to your PTO or hydraulic control.

I really like the idea of having it mounted to the loader. You could then pour the concrete anywhere you want.
