Did you pull the long power take off shaft. It is splined right to a hub in the flywheel?

If you have been pulling on the engine with this shafty still in the tractor I suggest you take it all the way out and checkmto make sure it is still straight. If not it can be straightened. This happened to me the first time I had a tractor worked on. Fellow I had work on the 1855 apparently hadn't worked on Olivers before and tried to pull the engine with the PTO drive shaft still in the tractor. Put it back in bent. Made the clutch drag. Pulled the shaft, rolled it across the floor and bent the shaft back with a press. I was lucky.

Ryan, the pto shaft, as you see it on the back of the tractor, remains in place. There is a long drive shaft, however, that is splined into the engine flywheel that runs all the way through the transmission/rear end that must be slid out so that it is completely disengaged from the engine flywheel; it must in fact be pulled out as far as the transmission input shaft, where the coupler you slid back is. At the rear of the tractor, you'll see the cover for the dry pto clutch retained by 4 capscrews on the bottom side of this cover. Remove them, then engage the pto lever on the tractor to remove the cover. Behind the pto clutch assembly you'll see 3 capscrews; remove them and then pull on the pto clutch assembly. It may be seized where it is splined into the flywheel hub, but it will come out and can either be removed completely or just slide it out and leave it hang out the back of the tractor about 5 feet. You can then remove the engine. Good luck...
