I never tried to haul mixed concrete. Frankly it all sounds more trouble than it is worth. I have always done my own mixing for small jobs, am now 68 and still do my own mixing when needed. The key is to find ways to minimize the lifting. I buy 60 lb sacks and get it loaded onto a pallet in the pickup by the sturdy lads at Lowes, about 1000 lbs at a time. Use the tractor and forks to lift it out of the pickup. Switch to loader bucket. Empty the sacks into the loader bucket at ground level. Then raise the bucket to chest height which makes shoveling into the mixer a breeze. I do not use it much these days, but I keep this mixer around, it always starts on the first pull and does a fast good job of mixing. I have a big old construction wheelbarrow but I only fill it half way to make moving it easier. For the small jobs I do around our property this is the way to go. I wouldn't mind paying the minimum fee for ready mix, but I am usually working in a place where a big truck cannot go, and on projects where the concrete cannot be dumped all in one place anyway. And another thing is, around here it is pretty hard to find a young helper who actually wants to work. They like to get paid but the work part is a different story. So I work in small batches at my own pace.
