Hi Doggman, If you are talking about the big round bales, I would say not to do it . Out hay was dense and weighed about 1600 lbs a roll. Among other things,it would probably spread out the sides of the bed. Then when you spear it with the the spear on the tractor loader,to take it off , you would have to push to get the spear in . I think this would be rough on the unit. There are some smaller round balers out there and I don't know what they weight bales they put out. The big ones I was talking are about 5 feet tall. We quit feeding big bales when we got the feed/mixer wagons.These are each connected to a dedicated tractor. Now we get 18 wheeler loads of corn gluten from Memphis ,the same of cotton seed and gin mote. {Stored under the big barn} I load this with the Cat 252B.We add minerals, mix and drive by troughs we made out of split big oilfield pipe {weighs 86 lbs a foot after split } and auger the mixed feed out.I made lanes around the troughs with electric fencing and run the cows out with the RTV when they are though eating . This is how we can farm amost a 1,000 acres with just us 3 and we have free time. and have nice looking animals.We use to have 2 hired hands when we did the hay.Using the RTV and feed wagons made a big difference here but just not with big hay bales. I sprayed selective herbicide on so much pasture with the RTV that we didn't even use the clipper this year. Now you neighbor would love that idea.Good Luck, Bordercollie[&]
