JD 2030 losing power steering and pto

I own a John Deere 2030 tractor made in Mannheim. After a time bushhogging, my power steering becomes hard to steer, the bushhog almost won't cut, and the 3 pt lift arms will drop if I have the 'hog up. By moving the pto lever from "Engage" to "Disengage" and immediately back to engaged, the steering gets easy to turn again, the bushhog starts cutting better and will lift back up if it had dropped down any. I have cleaned the hydraulic fluid intake screen to the trans pump, put on a new hydraulic fluid filter, and topped off the hydraulic fluid with the engine running- and it still has the same problem. Since I have a pto off-on lever, I believe it has an independent pto (but the pto turns all the time the engine is running), and the pto brake won't slow the pto down at all in "Disengage". I don't know if the steering could recover so fast if the hyd. lines to the pto clutch were broke, or if the pressure control valve needs a rebuild, but I need your advice before I spend too much having it split in half.

sometimes the tubes from the shift lever cover, which it the valve block for the low pressure system, are touching the shifter shafts under the cover and get holes in them. a hole in the pto clutch line will reduce pressure in the pto clutch and create slippage. on the other hand, oil lost through the hole will be missed by the main pump, this can cause problems in the high pressure system.
even with no high pressure, when lift arms are up (in 'd' sesitivity),they should not drop. if they do there is another problem there that can contribute to the other problems.
you shold check the low pressure in low rpm and look for changes between pto on and off positions.
