Spiveyman...how are you folks doing on hay in your neck of the woods in Kentucky? Around here, rolled hay (grass hay that is) is going for around $75-$80 a roll for cows. Alfafa is going over $100 a roll, even seen it up to $125. Word is around here (Franklin, just south of Bowling Green), hay will be scarce during winter months in my neck of the woods.
As for rear ballast, my rear tires are loaded and they get light carrying a 2000 lbs of rolled hay. I have a 55 gallon drum that I had filled with concrete last fall when I poured a sidewalk. The driver asked me where I wanted the extra concrete poured of what was left over and I told him to put it in the drum I had set aside. He knew right away what it was for. He told me his company fills them all the time for people that need ballast for there tractors. Some contractors wont let the driver pour out what they have left over on the job sight. So the driver takes it back to the company and they have a place they dump it. If you dont want to buy and mix concrete, you might call your local concrete company and ask if they will fill it with waist concrete that they have left over from a construction sight. I dont think they charge very much for it since you are doing them a favor of taking there waist concrete from them. Just might be a option that you could/can look into. What I did was cut the top off my plastic drum, I cut just enough of the top just to get the top off. The driver was able to get 60 gallons of concrete in it. My concrete does not have rock in it. When I took it into town to have the southern states weigh station weigh it, they said it weighs a little over 1200 pounds. All I did was cut two holes in it for the drawbar to slide through it and welded a 3"x3"x1/4" steel tube to the drawbar. I still need to finish the top link for it. But until I finish the top link, I just use a chain so that I can chain the top link to the square steel tube. Using this ballast is like night and day when moving rolls of hay or doing dirt work. Maybe this thread will make me finish the top link. I got a back seat driver saying to me right now that I wont finish it until the chain slips off it and I broke something on my tractor. Funny thing is, she is probably right. Think I might prove her wrong tomorrow. We'll see, just depends on this Kentucky heat where having.
