Lift the mower to an upright position and secure (so it doesn't fall on you) 4. Remove the engine crankshft pulley, along with that end of the belt, by removing the crankshaft bolt (pay attention to how it comes off) 5. Unscrew the "Forward/ Reverse" knob, remove the plate beneath the knob to give access to the PTO pulley. (be sure to unplug the SAFETY device from the bottom of plate) 6. Remove the SNAP RING from the PTO pulley, and remove the pulley (pay attention how it comes off. Which belt where? MY pulley was a double pulley, of which one side "Floated") 7. Remove the clip (spring) from the Forward/ Reverse lever that is about half way down the shaft, and to the left of the pulley. Give it a twist and squeeze to the right. (This is tricky to put back on. PAY ATTENTION. The "U" part of the clip will go on the BACK side of the shaft when reinstalling. Then use pliers and/ or screwdriver to push the other part over the front side to catch the shaft) 8. Pull the tension pulley away and remove the rear drive belt.

which one? there are two belts. take off the shift knob and access panel (two screws) remove clip on the varispeed pulley and pull up and remove the top belt which is the rear one and then you can also remove the bottom belt which is the front one, then to remove front belt you will have to first remove deck belt at the engine pulley and then remove the pulley to drop it down so you can remove the front drive belt. the installation is the reverse. the rear belt is kinda harder to install, just get it started on the rear pulley and walk it on, it is sometimes easier to remove the battery and the insert to get at it better. sometimes you will have to do some adjustments but not always. Get the manual somewhere on the web which will tell how to change belt and adjust as necessary.
