Looking around on the internet youtube the cheapest thing out there for moving rond bales is a roll behind device at Tractor Supply Company for $999.00.
I have a sub-compact diesel Massey Ferguson, the specs say the 3 point hitch can lift 1190 lbs. I read that the biggest round bales weigh about 1500lbs, so that ain't going to work!
You tube shows a "round bale dolly" that looks cool, but can't find where to buy!
I was thinking of maybe trying to get a hood from a car at a junk yard, and seeing if I could roll a bale on it and just drag it.
