Sky, The smaller bags are often available at the big box stores where many customers aren't really candidates for handling the big bags. The Home Depot I used to frequent had its Redi-Crete in 60 lb bags. I used to buy it by the pallet (about 3500 lbs, including the pallet.) I always had he same conversation about delivery. "Just put it in the bed of my pickup." "But sir, it will overload you, we have had customers not make it out of the parking lot, etc etc. One ton dually Dodge with 10,000 lb air bags and custom overloads. Had less than 2 miles to drive.
I have the little Red Lion brand electric mixer. It will just barely hold 3 of the 60 lb bags and the required water so it makes 200 lbs of crete per batch. I have learned that when dumping into 5 gal plastic buckets to let the 200 lbs be 3 partial buckets or they get too heavy too fast.
I bought the mixer assembled as floor model and got discount. Unfortunately the store folks did not attach the motor guard bracket and worse yet I didn't know it was supposed to have one (no manual.) Unit got tipped over (empty, just moving it around) and the motor struck the pavement bending the drive sprocket which defied straightening.
I now use a
3PH PTO powered mixer. (haven't turned it and the tractor over yet
)
