So I purchased a house and a Massey Ferguson 35 (70s ish? I can not find a date or serial number) came with it. After a little work the, tractor runs. I was checking the fluids and the transmission / hydraulic fluid looked milky (I assumed it had gotten water in it?). I drained out the old fluid and replaced it with a universal Tractor Hydraulic oil. It took 6 gallons and the dip stick says its full. However now the tractor will move with no issues but the hydraulic arms for the 3 point hitch will not move. And I have an oil leak around the PTO. (I am assuming the PTO needs a new seal?) Any help would be greatly appreciated.
