A deck belt replacement should begin with the correct deck identification and end with a guarded, checked cutting system. There is no universal routing diagram for all mower decks.
Before removal: identify the deck
Record the mower and deck identifiers, then locate the belt reference and diagram in the correct manual. A deck of the same width can still use a different belt. Check whether the job concerns the engine-to-deck belt or a belt linking blade pulleys.
Make the machine safe
Park securely, switch off and prevent accidental starting using the manufacturer’s isolation instructions. Allow movement to stop and hot parts to cool. Use only the specified deck service or removal position and suitable supports. Keep hands away from sharp blade edges.
During fitting: follow the diagram
Use the manual’s tension-release and guard-removal sequence. Inspect accessible components for damage before installing the replacement. Do not force a belt over pulley flanges or use a guessed route. If the deck has a timed blade system, its timing procedure is essential.
After fitting: inspect before testing
Check the belt path, seating and freedom from twists with power isolated. Reinstall guards and use the specified tension settings, where adjustable. Test only as the manual directs; stop if there is unusual noise, vibration or smell. Recheck through the approved service procedure.

Can I use a similar deck’s diagram?
Use only the diagram that applies to your deck model and serial range.
