You must disconnect the rubber coupling between the engine and input shaft to the transmission. There is three bolts that connect the coupling to the engine, they are threaded right into the crankshaft. The remaining three are bolts with nuts that connect the coupling to the drive shaft. You must completely remove the coupling in order to change the alternator/water pump belt. I just changed mine, however I had the radiator out due to head gasket and water pump replacement. I think you should be able to do this from underneath the tractor.
you must take out the four bolts holding the hydraulic pump to the engine, located just below the front radiator about 6 inches. After the bolts are out you are looking at a flat side which connects to the fluid pump and the other side has two aluminum humps one on each side of the of the part that connects to the engine. you can manipulate this part to give you a small space that you can fold and incert the belt, then pull the belt thru to the outside of the motor to pump connection. It doesn't just slip thru the gaps, you have to force them thru. Needless to say, you need to replace the AC compressor belt at the same time. I was replacing the water pump, so I had everything off from the block forward to the radiator.
CAT IN THE HAT
Remove the alternator and disconnect the hydraulic pump the belt will fit over the fan. Then reconnect
