Agitator

Newrock or redrock superflow would do the trick

My advice is stay away from anything with a flap on the spout, seems to spread the jet of slurry. Like Reggie said newrock/redrock, hardrock are also the same.

Standard flow would be well able for what you're mixing so if theres anything to be saved between it and the super flow then I'd hold on to the extra money myself. Mixing a 4 bay single and 2 bay double with suspended passage here with the standard flow and can move the full 4 bays from 1 end.

Some of the smaller stuff isn't compatible.

A while back I was agitating an outdoor tank with a cross. Lovely job as you could see exactly what you were doing.

2 hours finished . Farmer remarked how quick I was doing it.

Previous year a neighbour agitated it and was the bones of 2 days doing it

I like the look of the cross, but the size of the base would make it incompatible with every tank we have.

That's an interesting thought. We have an NC Super flow and are unimpressed with it.
