GVW, I had a IH 340 Utility (about 1958 model?)until about 6 years ago. It also had power steering, live pto and a torque amplifier, but it didn't have position or draft control. I never tried to dig post holes with it, but putting down pressure on a disc or blade only made the wheels spin. I kept that tractor 15 years and got good use from it, but I really enjoy my more modern Kubota!!
