No manual?
The mower decks come off quite easy.
Raise the deck, and drop the deck stop to the lowest level. Lower the wheels on each deck corner. Lower the deck to set on the deck wheels. Turn the tractor wheels for a right turn, and then turn off the tractor.
Reach ahead of the rear axle and disconnect the PTO (slide forward the lock ring, and slide off the shaft) I lay on the deck to reach it and have the right rear tractor wheel out of the way to reach it better.
Then release the front bail (draft bar) that will lower the front of the deck. Then pull the two spring loaded J bolts on the lift arms. Start the tractor and raise the lift arms out of the way.
Then slide the deck out one side or the other.
For the blade, first install the hitch and the hyd. lines. Then use it to pick up the blade.
All this should be in the manual (s)
