Concrete and PTO

We finally dug our foundation out with the Case 580C. Now I'm looking for a concrete mixer that runs off a PTO. Would like something that can do a yard. I have 28 yards to pour for the walls and 14 yards for the cement pad. I have a bout 400 bags of 80lb Portland in the barn.. gears are turning here.

Do they make a pumper for a PTO? Case has a PTO but I will run it off the ole MF165 tractor with a 60hp perkins.

northern tool sells one 5 cu ft you might find a used one for sale somewhere that is 3 point mount . i didnt see any thing about pto driven concrete pumps

That's a lot of concrete to do in a small mixer assuming you're going to shovel in the sand, gravel and cement by hand. I hope you have a lot of help.

27 cu. ft is a big mixer to load by hand.
You could set up a chute and load it with the backhoe.
We have one of these 16 cu. ft. mixers that works very well, also available as one yard.
They are directly driven by hyd. motor.
Initially had it on a Ford 4610, which worked ok, but engine rpm had to be increased as the mixer was loaded to maintain a suitable speed.
We now have it on a JD 6320 with pressure flow compensated hyd. system....Set a suitable speed and forget.
We recently had a large(ish) concrete project and looked at buying an old, truck mounted, agitator and loading it with a loader etc.
Also priced some large European ribbon mixers but found them too expensive.
Ended up putting the money into readymix and saving a lot of headaches.

378 wheel barrows of concrete by hand isn't to bad if your really ambitious or say it fast.

28 yards is a lot to place, never mind mix in small batches. You don't want to get hot spots in your slab or foundation. A

I just finished site mixing 27 cu. yards of concrete over 1 week. I made a hopper to go on the front of my tractor. I purchased bulk sand, pea gravel and portland cement by the bag. The hopper was placed at the material which was easily shoveled in as it was below knee level. Then taken to each of three 9 cu ft mixers I rented then dumped into a auger bucket on the front of a CTL which transported and dispensed the concrete around each 12"x 12" piling. I had to do it this way as we drilled each shaft, set each piling then dispensed the concrete. Ready mix was not an option. This method was much less expensive and easier than lifting 80# bags to shoulder height.

That's what came to my mind at first as well Blazin. Mixing 28 yards of mud for a wall pour by hand will produce cold joints in your wall which may or may not be an issue later on.

How long will it take you to mix one yard and place it in the wall? For example - if it takes 15 mins to mix the mud and get it placed in the wall forms then it will take 7 hours to mix and pour the wall, there will be cold joints.

I wouldn't do it for the wall pour nor the slab pour. If you want to use your materials on hand you might try the footings, just make sure you overkill the rebar for the cold joints.

Another thing to consider is getting the proper mix when mixing so much in small batches. 3K PSI is minimum for a residential wall, quality control can be an issue.

Bannerd it's a lofty goal and I wish you the best if you go this route but I would highly recommend against it.:cool2

I think my plan is to just have concrete trucks show up, use the case loader and then dump that where needed. I cannot find a mixer the size I want.. they're out there but the cost is that of your own concrete truck. My issue is the foundation is in the side of a hill and will need a frost wall. The truck chutes are 10 ft which will reach in some places.. but the foundation is on a mild slope and we have some big maples we don't want to down. I have the over sized bucket for the case so it should go quick if I did it that way for the footers, frost wall and floor.

Pumpers are pricey up here, $900 for four hours plus some money per yard poured, plus delivery. Might need the pumper for the ICF walls though. 2foot lifts 8ft walls.. hour in between should work.

Be careful with the "Over size" bucket.
Concrete is very heavy per yd.

Done that. When I was a kid, maybe 50 years ago, my father was in demand. He was a powerful man, able to push a wheelbarrow up a tall ramp. The guy who always shoveled gravel into the mixer was old, probably 60. My job was the Portland. A foundation crew was invariably Saturday. Usually ten men for a pour. Two brothers had identical gas powered (Wisconsin twin cylinder) mixers. while one batch was mixing, the hopper was being loaded for the next. A hand crank winch pulled the scoop shaped hopper up to dump into the mixer. As I recall they each mixed five wheelbarrow loads in constant mix. One foundation was for the third brother of the mixer owners. He had a new tractor A Fordson Dexta my father dubbed it the Rattlin' blue Devil. It had a three point backhoe. My father suggested using the backhoe to load mixers. The owner refused. They would pour up to 40 yards a day.

These days we call for ready mix

This Wisconsin mixer is over Forty years old!

Dad has a mixer from the 1970's, old Gilson with a Wisconsin engine.

Looks like this;

I think it does about three yards or more. It's a brute. I'll take pictures of the excavation this weekend. Just not sure how I will get cement to the site.

You guys sure you're not forgetting a few decades? BlazinSS, did you mean that mixer is ONLY 40 years old? as in from the 70's.

Bannerd, that picture looks like a relatively new model, but that style of mixer was more common in the 20's and 30's than the 70's.

Those are two chunks newer than what I speak of. They are similar. If the weeds aren't too tall, one is still around, I'll get a picture. This is an old family. An adjacent town was named for them. They changed the name to Peru????? Now there is a ski area bearing their name. They refer to the new engine on the saw mill. It was bought in 1928 when the great grandfather was getting fed up with ongoing problems with the steam engine it had before. He disappeared in his T, and came back saying it'd be delivered after lunch.

They still talk of how they never got anything new until Delos got mad. The "Boys" (all dead now). The last passed a few years ago at 93, would intentionally figure out a way to make their father mad. One effort on their part yielded a new 1939 Farmall M, the first of its kind in town. They still use it today. It is unrestored functional now. The paint is worn off the nose cone from chopping corn. It has never spent a night outdoors.

lol yea it's with a 75 or 76. Can't tell the label is damaged. But that beast runs 5-6 hours straight and sips gasoline. Oh and starts on the first pull every time!
