It is to bad if we knew where you were perhaps someone could help in person.
You can try and adjust but if the clutch is worn it is not going to help.
If your a big guy your going to want to pull the drivers seat. to get your head and shoulders to a point you can see.
Loosen the lock nut screw the rod out you might want to check it could be screwed out all the way already .
This only adjusts free play and pedal height it does not adjust the clutch .
