I have a Furukawa loader it has a 1/2 yard bucket, when I was building my shop, getting a pumper up the mountain was expensive, $1,000 to $1,400 a time when we did the footings, I tacked in a couple of pieces of angled plate to give me a pour spout about 2 feet wide.
The truck could get-to about 1/2 the footings they poured from as far as they could I had the loader in the middle, he would fill the footings then fill the bucket and I did the part he could not get to when the job was done I ground out the plate. For the cost of a 4 ft square piece of steel cut and ground to fit it saved me a grand.
When we poured the walls I put the pieces back in and used it to redo a cracked section of sidewalk and make a ramp, to my back yard picnic table, barbecue area. Both of those areas were about a thousand ft from the pumper.
Worked for me!
