This is a little embarrassing since I grew up on a farm, but... I have a 6 1/2 ' offset wheeled disc (not 3pt). I also have a 50hp tractor. I'm pretty sure have the power to pull it but the tractor struggles with it as far as slippage goes. I filled the rear tires with water and that helped but the tractor still snatches and grabs and I have to use the interlock nearly all the time. Of course, I also have all the angle in the disc but I don't run the wheels all the way up and it still bogs. I grew up running a 12' tandem cutting disc behind a 5020 JD (133HP) and currently use the same disc behind a 4320 JD (116HP). I really think my main problem is lack on weight on my 50hp tractor. Anyway, any suggestions would be helpful. By the way, adjusting the angle on the offset disc is a real pain..
