70 HP Tractor Disk Size

[Soggy Bottom]

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. I am wanting a disk with wheels and not a 3 point. Thanks

Are you plowing first, or discing up sod? Or stubble?

in broke dirt 10' is about all you want. If your disking pasture you might get away with 12' but it will be a load if your cutting hard

 

[Soggy Bottom]

This will be disking pasture at first than disking broke up ground after a couple times a year.

I would not go bigger than 10' for all around use. Buy a good quality heavy one.

I have a 12 foot that I pull with a 6610 Ford. Pulls it fine.

John Deere DH1512 12 foot disc harrow 2,699 lbs rated at 55 - 85 hp
JD DH1510 10 ft 6 inch 2,480 lbs rated 45 - 75 hp

A lot depends on the disk. A heavy offset disk 6 foot will be too much, even a heavy tandem with large notched disks set aggressive a 10' maybe too much. A lighter finishing disk you could pull 12+ feet.

I have a JD 10 foot and in loose ground it's all my IH684 can do to pull it.. in sod or hard ground it pulls it like a breeze

Thanks for the info. I may get a good heavy 8 footer to be on the safe side.

That's what I'd probably do.

Not written in stone but good rule of thumb is 10hp per foot of disc. A heavy 8’ or decently built 10’ would probably be my recommendation. With FWA you could probably handle 12’ most of the time but I’d rather have one a little bit small and be able to run in the 6 mph range than have on too big and have to run at 4 mph.

I have a 10' I pull with a 60hp 2wd and I think it is perfect. In loose soil if pulling uphill it is all the tractor wants but with 70hp and front assist I think you would be fine. A 'transport' disc is what they call one with wheels.

A good well built disk with good blades. 8-10 foot nothing more. When you drop a good disk in worked ground you know it's back there. I perfer ih disk

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)
IF your 70 hp tractor only has 55 hp at draw bar you might need to lift up a bit, uphill in loose dirt.
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.

That's bang on. I have an old Kello Built 10' with I think 28" discs and 11" spacing that a 70hp tractor wouldn't move. There is a lot more at play than just width.

I have a 18' case ih 496 7'' spacing. I pull it with a 150hp 1086 with duals. I would not want any less tractor.

When you drop a good disk in worked ground you know it's back there. I prefer ih disk

Ahhh, yours is an 18 footer. Now it makes sense, as it's been a long time since I've even seen a
case-ih less than 12 foot.

1086 IH pto 146 hp drawbar 120 hp
I'm thinking his 70 hp NH is probably drawbar 55 hp

I’ve got a 14’ John Deere 210. And I’ve got a 12’ international that the numbers are worn off. The Deere cuts way better hands down. The international blows it away when it comes to leveling. I usually make a pass with both.

i just bought a 14' to pull with my 65hp. I have a 8' and its like nothing is back there.. it seems way too small.
