We use two hungry 1800 lb. Beef cows... oh wait. That's how we hide the round bales. You just need to move them. :)
We use the pallet forks on our new holland. We just slip them under the bale and lift. Works great for us going short distances. I'm not sure how much the bales weigh, but I don't think they're quite that heavy. Usually one person can roll them where they need to go.
I've never tried rolling any of mine by hand (they average 800-1000 pounds too) because they always seem to have that one flat side....and I'm too lazy LOL.
I have used a saddle horse to pull a bale off the back of a pickup though. Once I put a rope around the bale and the other time I had a rope tied to a hay hook (I don't advise that, though, because it's really dangerous).
Those little trailers with the spikes and winch are really common around here, there must be someone who mass-produces them.
I did a search for a "bale trailer" and came up with this. These are really handy and just about any vehicle can manage a bale on here.
Edited to add: You might do a search for an "ATV bale trailer". It seems that is what those things are most often called.
When we lived in TX those were the things to have, the bale dollies/trailer! So cool!
I could never find one used and cheap enough to justify it because they were in high demand- hence the rolling the bale out of the pickup by slamming on the brakes..LOL!
Now we get the big 1200-1500 lb. Square bales and I have hubby throw a couple on the back of the hay trailer when he loads at a ranch that has good horse hay and I pull them off with the pickup and a chain in the driveway.
A tractor and a set of hay spikes are on my list to send to Santa :)
