Here is the sequence from the JD manual:
1. Stop tractor on a hard, level surface. Such as a cement floor.
2. Raise mower as high as it will go by pulling hydraulic lever backward.
3. Adjust the mower deck depth stop to the lowest cut height setting.
4. Turn front wheels to the left.
5. Put rear gauge wheels in the sideways position.
6. Lower mower to the ground by pushing hydraulic lever forward.
7. Stop the engine.
8. Put the park brake in the LOCKED position.
9. wait for ALL moving parts to STOP.
10. Pull spring loaded pin OUTWARD and rotate handle FORWARD. (This is on the front of the tractor)
11. Slide mower pivot rod out of slots. (on front of tractor)
12. Remove front draft rod of mower front draft assembly from slotted bracket on mower deck.
13 Remove front draft assembly from underneath tractor.
14. Pull each spring loaded J-pin out of each mower bracket and each tractor lift arm.
15. Lift right side rear tractor lift amr and LOCK into the UP position with J-pin.
16. Lift left side rear tractor lift arm and LOCK into the UP position with J-pin.
17. Remove driveshaft from tractor shaft by pulling collar on locking coupler back and pulling shaft from splines.
18. Turn front gauge wheels so they roll toward right side of tractor.
19. Roll mower deck out from right side of tractor.
JD provides an additional note that if the tractor is equipped with the 26x12x12 tires, it may be necessary to remove the left-hand rear gauge wheel. I have found it easier just to raise the back of the tractor a couple of inches with a hydraulic jack.
You will need to order a manual on the mower from the manufacturer (I assume Simplicity).

You will need to remove the cutting deck to get to the blades. Here you will find the drive belt, which you just slip off.

As long as they are close to the same year and model, yes. I have two decks side by side, one 38" and one 42", and all the brackets are the same. The belt will need to be changed for a longer one, though.
Look for a 3/8 drain plug underneath the deck (where the blade is) Loosen. Drain. If no plug is there, remove the oil dip stick and turn the mower on the side until all the oil is out.
most likely 2, look underneath

just get new belts they stretch or buy a can of belt grip
To install the idler spring on a 38-inch mower deck, first, ensure the mower is turned off and disconnected from power. Locate the idler pulley and the spring mounting points on the deck. Attach one end of the spring to the idler arm and the other end to the designated anchor point on the mower deck, ensuring it's securely in place. Finally, check the tension and adjust if necessary to ensure proper operation.
