I used two different 3pt pto cement mixers and self mixed many yards. Great for short yards and places a cement truck couldn’t go.
Then bought a multi quip trailer type gas driven mixer. Liked loader able to help lift Portland, sand, gravel and then transport and place the mix. It has forklift loops for moving while empty. Two DIY modifications I’ve wanted to pursue. 1) Funnel bucket or funnel/chute to charge ingredients to the mixer with the tractor FEL. This would include a 3pt mixer. 2) stronger forklift pockets to transport a loaded stand alone mixer.
