For Craftsman rotary lawn mower model 917377582, the year is not determined by the model number itself. The model number identifies the mower family, while the manufacture date is typically found on the product ID tag (often shown as a date code) and in some cases referenced in the 917377582 owner's manual.

We recommend checking the mower’s product identification label first; that label is what ties your specific unit to a build date.

• Look for a sticker or metal tag on the rear of the deck, near the height adjusters, or around the handle mounting area
• Check near the engine shroud for an engine label (your manual lists an engine model family)
• Write down any date code or serial number exactly as shown
• Compare the label info to the identification section in the 917377582 owner's manual
• If the label is worn, clean it gently and use a flashlight to read stamped characters

Knowing the correct year helps you avoid ordering the wrong blade, drive parts, or controls when there were mid-production changes. For example, drive system parts like the belt 532157769 must match the exact configuration used on your mower.
