How to install a belt for a 42'' Murray mowing deck?

To install a belt on a 42'' Murray mowing deck, first, ensure the mower is turned off and disconnected from the power source. Remove the deck from the mower by detaching the pins or bolts securing it. Once the deck is removed, locate the old belt and note its routing; then, remove it from the pulleys. Install the new belt by following the same path as the old one, ensuring it sits properly in the pulleys, and reassemble the deck back onto the mower.
