JD 2020 No Hydraulics or PTO

Just acquired an early 2020 with the hydraulics and the ptos not working. There is no flow from the transmission pump and neither the rear or mid pto turn. The previous owner said he hit something real hard while bush hogging and everything quit. What is the common point to both systems in the transmission that will cause this problem? Do you have a picture of the system?
 
My operators manual calls it a transmission driven pto. "The single 540 rpm trans driven pto is driven by the transmission clutch shaft and
its operation is dependent on the engine single stage clutch." I just look at the clutch thru the inspection hole on the right side of the
bellhousing and it looks like a single stage clutch. In the 10 feet that I have driven it, the clutch needs to almost out to engage the
transmission. This is a 66 model by the serial number.
 

Not trying to be smart Alec but there is no inspection hole in RH side of clutch housing. Inspection holes in 2020 clutch housing are in LH (drivers) side). I suppose you only saw 3 pressure plate fingers and one throw out brg??? Are you positive your operators manual is for your tractor?
 
Your right the inspection hole is on the left side of the bellhousing but no matter what side its still looks like a single pressure plate
and throw out bearing. Is not the transmission driven pto the standard and the others would be special order upgrade items? S# 5r3c 022978t
Do you have a picture of what you think is broken?
 

I can't remember which style pto was standard when I sold them when they were new. I think mid-pto option will not be transmission driven but I will need to do some research.
 
All of those tractors only had 3 clutch fingers. The two stage clutch had three pins in the
clutch cover that the fingers hit when depressed about half way. The pins released the pto
clutch as the pedal was pushed all the way down.
 
I already put the tractor in the shop, drained the water and took the batteries out for the winter. So no longer able to start and run it.
 
(quoted from post at 18:48:16 10/16/16) I already put the tractor in the shop, drained the water and took the batteries out for the winter. So no longer able to start and run it.

Put trans in 8th gear & rock rear wheel then observe engine fan to see if fan moves.
 
I was able to drive it from where the tow truck dropped it into the shop, about 10ft and let it run while I checked pump and pto operation. I didn't want to run it anymore without fluid to the
front pump. I'll move the tractor in gear if you still think it necessary. Thanks
 
Ok so what else is the common denominator? Both hydraulics and pto stopped working at the same time.
