Disc harrow size for MF 1433?

[Woodgoat]

Howdy do. New guy here and I've enjoyed reading for the past two days. I need some advice about a MF 1433. I'm fixing to buy one and will be using it for planting food plots, bush hogging a field and some hunting trails and maintaining a 1500 ft gravel driveway. It's got a FEL on it and I've got a 5' bush hog, but was wondering what size disc harrow this little machine would comfortably pull? Thanks
