Place the mower on a flat, level surface and set the parking brake to keep the mower from rolling while you're working.
Open the hood and remove the spark plug wire(s). Ground the spark plug wire (s) against the engine to prevent it from starting during lawn mower maintenance.
Remove the cutting deck. Instructions for removing the cutting deck can be found in your Operator's Manual in the "Service" section. Then lift the seat to gain access to the battery. When disconnecting the battery, always disconnect the black negative battery cable first, and then disconnect the red positive battery cable.
Look down through where the battery was located. You will see a large transaxle pulley. Loosen the large nut holding the pulley to the input shaft using a 7/16" socket.
Disconnect the spring from the anchor bolt on the left side of the tractor using a spring puller or a small piece of rope. This will relieve tension on the upper drive belt. Note: Orientation of left and right is determined from the operator's position in the seat.
Maneuver the upper (rear) belt from the transaxle pulley and remove the belt from the mower. Next, remove the belt guide from the variable speed pulley bracket using a 1/4" socket. Note: These are all accessed through the battery compartment.
Lift the middle sheave slightly so the lawn mower belt will clear the belt guide, and slip the belt off of the variable speed pulley.
Remove the bolt securing the crankshaft pulley using a 5/8" socket. Note: The use of an air impact gun is recommended for removal purposes. If not, use a strap wrench to hold the crankshaft pulley while loosening the bolt.
Lawn mower belt installation is essentially the removal process in reverse. As you install the new lower drive belt, confirm the correct belt routing inside of all the belt keepers and through all the guide pins using the pictures taken before the lawn mower belt removal.
Apply a very small quantity of anti-seize compound to the engine crankshaft. This will help ease the crankshaft removal in the future when needed. Note: DO NOT get any anti-seize compound on the bolt threads or in the bolt hole of the crankshaft.
