Zetor 6745 hydraulic pressure low

[mpr128]

I'm slowly working through all the faults in an old 6745 I've just bought.

Finally got it running and found the hydraulic pressure is low.
It struggles to lift my disc mower and doesn't have the strength to fold it up (there is a ram on the mower plugged into a port on the tractor), even at high revs.

I'll pull out my workshop manual tomorrow and find out where the hydraulic filter is. If it's anything like my other tractors it will be buried in the hydraulic fluid tank. Is my Zetor any different ?

If the filter is ok, is there anything else to check before assuming the hydraulic pump is worn out ?

Is there a repair kit available for the hydraulic pump or is it a throw away item ?

thank you

I bought a used hydraulic pump out of another Zetor . Had to remove it myself, cost about $US30.
Unknown condition. Will fit it in winter.
I've been using my 6745 all through summer to pull my Welger AP71 hay baler around and it works well.
Plenty of power to run the baler. Lots of weight & traction to get it up hills.
