Hi How do I change a drive belt on a try built front wheel drive 21" lawn mower?

Usually there is a belt cover between the front wheels that must be removed to reveal the transmission. The transmission can be tilted backwards either by removing or pulling against a spring, or by backing out a screw that runs down to the deck. Either way, the trans tilts backwards to take tension off the belt, slip the belt off the trans pulley, feed it back through the hole between the deck and the engine, down around the blade and off. Feed the new belt up around the blade and out to the trans, reverse previous process.
