I have a New Holland 70 hp that weights 6500-7000lbs. It is front wheel assist tractor with 600lb of rear wheel weights. What is a comfortable size tandem disk harrow I can pull? It is black land I will be disking.
Seems answer has a wide range because of the wide range of disks available.
Your NH 70 hp fwa tractor will easily handle a JD DH1510
10 ft 6 in (45 hp minimum - 75 hp)
however It takes
95 hp to handle a Brush Hog 3D98
8 foot 0 inch with 22" notched discs 7.5" front 9" rear spacing
When you locate a disk for sale, look up the manufacturer's recommended hp for that model number.
