YES
maybe a one beer job.
you can use the opportunity to drain and change the hydraulic oil; when you drain it, just unbolt the 4 bolts around the shaft, pull the shaft out, and push in the new shaft, bolt it in and put in new oil.
or, do what I did(twenty some-odd years ago), park the tractor heading down a STEEP downhill, -this way the fluid won't drain out the back- then unbolt the 4 bolts etc... and you're on the way. No need to stand the tractor on its nose, just be reasonable; bad seals somewhere might leak and get some fluid in the clutch area, but otherwise, it works.
In either case don't forget the gasket before you insert the new shaft.
