Those Ford"s where at 540 pto speed around 1750 engine rpm. The engine would go to 2300-2400 rpm. So if you figure it out 1750/540 = 2400/740. The JD 990 does not get to 540 pto speed until around 2300 engine rpm. That is one reason I don"t like using those small compact tractors. If you need 540 pto speed you have to run them wide open even if you don"t need the horse power. There is no way to change the pto speed on the JD 990. The engine would not have any torque don"t at the lower engine speed any way.
Like an old equipment dealer always was saying: There are horses and there are ponies. These compacts are ponies.
