Coming back in after 8hrs in the fields, steering started to shudder as low oil. I stopped and checked oil ALL OK. Got back in the cab started up, and when i put it in gear, I got three beeps and a flashing "P" on the dash, this stops out of gear. Over the next 10 minutes of checking things, All hydraulics (Forks, Slasher and PTO) are totally non responsive.... Thanks in anticipation of your assistance.
