Disc harrow size for 47hp

[moparguy55]

Hello all have a 1547 massey hst 47hp 4wd
Industrial tires (rears are full) supposedly 36hp st wheels.
How wide of a disc can i pull? Or how big of a 3 point disc can i hang?Land has wet spots and a bit of incline in spots. It has left over corn stocks.

From what i see a pull disc is better for uneven grounds.

Thanks

A 2 row pull disc is better generally. I pull a 6 ft wide 8 ft long towner with articulating wheels. It's old and heavy but I added weight to cut the hard rocky soil here. My tractor has 52 hp so not much different than your tractor. It can be all I can pull or even stop me when it sinks but I have those wheels which can push down lifting the disc out of the soil when it gets buried. This disc set is made by Towner, nearly as old as me. In this picture the wheels are raising the disc off the ground for transport. I hope this helps

Yes, slightly. But you give up field maneuverability.

The key metric for Disk Harrow penetration is Disk Harrow total weight bearing on each pan. 35 pounds weight per pan is minimal. 50 pounds weight per pan is reasonably effective. The angle at which pans are set also affects penetration.

As your tractor has 4-WD I expect you can pull a Disk Harrow with pans 22" or 24" in diameter 72" to 84" wide at a good clip.

Monroe Tufline is a key independent supplier of Disk Harrows. You can calculate the weight bearing on each pan for Tufline's various models.

The disc is quite old. The wheels had a screw crank on it when it came to me. I put a hydraulic cylinder on it, much better plus I control the depth, like when it gets too deep or when making a sharp turn around. It's a solid old rig.
I don't use it as much as I used to though, open ground seeds weeds and mowing promotes grasses, so I gravitated towards mowing.

Your tractor would handle a 12 foot pull-type or an 8 ft 3-point. I certainly would recommend the pull-type as I’ve yet to see any 3 point disk that I thought was worth more than its weight in scrap metal. It takes many more passes with those, to get the ground sufficiently worked, wasting lots of fuel.

A 12 footer would be ok in ideal soil conditions. A 10 footer would let you get out there in less than ideal conditions, and that’s what I’d go for. I use a 8 foot pull type on my 43 hp 4wd and can pull that thru mud if I want to, without even knowing it’s behind me, at the most aggressive angle setting.

Is there 4 rows of disks or just two? What would a set up like that weigh?
