I used to be able to toss a regular bale to the 4th tier but I was a lot younger and in much better shape then. Now I doubt I could get one to the 2nd. On a bad day not to the first.That reminds me of Garrett Medicine Bear. He was a big old boy. Dad employed him one haying season but he was always showing up drunk. One day he was bucking bales with Dad driving and I was on the truck stacking. I was three tiers up and I heard an OOOF! I looked up in time to see a bale fly over my head missing the truck completely.
The next year we bought a pop-up loader.
Getting old and beat up sucks.
