What is the configuration for the belt on a John Deere 455 60 inch mower?

As it is made from the factory, you must remove the deck. Remove the four nuts that hold the belt guards on, unclip the four fasteners. Remove the two nuts on the top of the deck toward the front, that hold the bracket for the gearbox. Loosen the two at the back lower side of the bracket. Raise the bracket up enough to get the belt out.

To install just go in reverse. One thing to remember is after the belt is on, to set the

small lower isolator that slides out to the tension pulley. This keeps the idler pulley from backing off enough to let the belt come off the pulleys, when the PTO stops suddenly.

ALSO, if the belt comes off, the deck has to be removed to just put the belt back on the pulleys. I took my belt guards off and cut the slots out to the end so the cover it can be removed from above. Now to change, i lower the deck, unlatch the linkage, loosen the

four nuts remove the guards. Put the belt back on, without removing the deck!!!
