Harder to push clutch on a tractor with hyd. clutch assist means no pressure from MCV pump. This pump also provides pressure for steering, brakes and TA operation. If everything was working two weeks ago, it sounds like MCV pump has lost prime, possibly from low oil level. First, change hydraulic filter and clean bypass screen and fill transmission to full level on dipstick. Check the dump valve as others suggested. I would put a jack under the front end and get most weight off the wheels , then start engine. It might take a minute or more for the pump to prime , but I believe that it will. When it does cycle steering wheel from side to side full limit, also cycle clutch pedal, brakes and TA. When the pump primes and charges the system, you've got to get the air worked out of all parts of the system. Sometimes for unknown reasons these old tractors lose prime in the MCV pump. My 756 did a while back after it sat a couple of weeks while I was waiting to get a new injection pump delivered and installing it. Started it and no steering, brakes, etc. Managed to get it aimed downhill a little and parked it . Let it sit for a while and when I restarted it I heard the pump take hold of oil and prime. Everything worked and has since. Good luck.
