man they work great regardless of the land. we had a model 1069 in the mid and late 80'2 on our dairy. it was self proppeled and woudl haul 165 bales at once. took 10 to 15 minutes to pick up a load. great machines. the pull type ones are just as handy but dont hold as much hay in a load. but they defiently save time and money and back ache......if you can afford a good used self proppeled that is the way to go. they are out there any where from $10 to $60 or a pull type from $3500 to 20,000.......if you have any questions let me know, i can help out
