How much horseower to run a 9 ft discbine??

It will be a load for a 1650.

Not familiar with the numbers but if it is a pull type with conditioner rolls than I doubt it will.

Just a disc mower takes about 8 to 10 HP per ft.

Ouch it should run it but only at a very slow ground speed. Beter find another 15 hp if you got much to cut or want to make any time
 

Most manufacturers state 9ft rubber rolls need minimum 60 PTO HP

the "12 foot" ones need 85 PTO HP +

I've run a 1411 NH on a TL-100 (82 PTO HP) and it ran it fine, but you were gearing back on upgrades.
 
Don't know what you guys are cutting, but I pulled a NH 9 foot discbine with flail conditioner with a Farmall 666 last year. First cutting orchard grass averaged about 120 small squares/acre. Pulled at 5 MPH but would handle it at 7 MPH if I could stay in the seat. Book says 75 hp for this machine.
 
I've got a John Deere 925 with flail conditoner. I usually run it with a 4020 Diesel, and that is not a problem for it at all. I have run it with my 686 International Diesel, and it will do it, but she's grunting to do it. I have also used my Allis Chalmers 6070. Again, it will do it, but it's working it pretty hard. Only time the 4020 ever knows it's back there is when I get into heavy canary hay. By heavy we're talking hay as high as the fenders and thick!
 
I'd suggest the answer is, "It all depends"; what kind of hay are you planning on cutting? Had some sudex one wet year that got about 8 ft tall; 4020 would barely handle the 9 ft Tarrup in 1st gear...........
 
The neighbor runs a JD 1360 (a little over 9foot) with an 80hp tractor in heavy alfalfa/timothy at about 4 MPH and it growls pretty good. Another neighbor has a 9 foot Gehl with an AC 200 tractor (95 hp) and can run up to 5.5 MPH in heavy conditions. Most literature on that size discbine usually recommend 80 PTO hp or more.
Be prepared to run low gear with that size machine. I don't know how many machines are out there at 8 ft but I don't think you will be time efficient with 9 ft. Lighter grasses will obviously be less an issue. We run a 9ft sickle NH haybine. It allows us to make use of the lower hp tractors we still have.
 
I dont know anything about a 1650 Oliver. As to the discbine, 9 feet should do fine with anything over 80 horsepower in normal mowing conditions.
 
My son bought our 1990 NI nine foot discbine, runs it with his 3020 JD. We used it with the 4430 or 4240. Works fine for him.
 
Our 1650s and 1655 have no problem pulling our 8ft NH 408 Discbine. I normally mow in 4th direct or overdrive and if conditions permit, 5th under or direct.

Loaded tires, no loader.
 
I run a 1460 Deere on a NewHolland TS90 which is rated for 70 PTO... but the test says 77 PTO hp. The mower is a 9'9" Kuhn bar.
On first cut it makes the tractor whimper.
It runs it for as much silage as we chop, then the mower goes on the other tractor at about 105 hp. Works much better...
The hesston is supposed to take a bit less power with it's shaft drive bar, but I wouldn't bank on that.
You want 85 horse to make it 'functional'.

10 Hp per foot pretty much the norm up here on rubber rollers, more with flails. If you have lower HP try a vicon 281 km with 3 blades on each head. Does cut with less HP than 2 blades. Cuts better in down crop too.
 
My 2640JD(65hp) pulls a Gehl 2360 discbine pretty well. It measures 10' across the front apron. You know its back there but she cuts nice.
