3 To replace a transmission drive belt on a Cub Cadet LT1045 or LT 1050 you need to remove the deck, preferably put the front wheels up on blocks or stands, unplug the PTO power (directly under the engine, which can be a pain ), use an impact wrench (you need the speed of the impact wrench because the engine will turn) and a 5/8" socket and reverse the bolt out of the PTO. The PTO may be sized on there so you may want to tap it with a hammer and a block of wood carefully to release it. AT this point remove the 4 engine mount bolts from underneath (1/2" I believe). You will need to remove the left steering nut and arm to have access to the 4th bolt. Do not remove or replace engine mount bolts with impact wrench or bolts may break. Loosen old belt from tensioner pulley. Place pry bar under engine to slightly lift engine and move aft to expose belt from pulley and remove from pulley. Remove old belt from engine pulley first, transmission pulley last. Remember how belt goes around pulleys before doing so, draw a map if needed. You'll need to put the belt on the transmission pulley first then thread the belt up to the engine pulley. Carefully push engine back into place and exhaust pipes into forward muffler will take some patience. Bolt engine back on being careful not to over tighten bolts. Place steering arm and nut back in place. Thread your belt back through the pulleys and tensioner (make sure your spring is strong enough to tension the belt or buy a new one). The PTO is "keyed" on the shaft. Replace bolt and washer. Put your deck back on and you're ready to mow again. Give yourself an hour for this one.
