Tractor Barn is correct. Be sure that you don't confuse live hydraulics and live PTO. In general, if the hydraulic pump is on the engine, the tractor has "live" hydraulics that are unaffected by the PTO or clutch. If the hydraulic pump is on the rear of the tractor or in the transmission, the hydraulics only work while the clutch is "out".
So it is possible to have a tractor with live hydraulics without having live PTO. Lots of customers confuse the two because of experience with old Ford or Massey tractors where the hydraulic pump, pto, and transmission ran off the same shaft.
