Craftsman 917370930 lawn mower Parts

Common problems we see on the Craftsman 917370930 walk-behind mower include hard starting or no-start, loss of self-propel drive, excessive vibration, and poor cutting quality. Most issues trace back to fuel quality, routine maintenance (air filter, spark plug, blade), or wear items like the drive belt.

Most common symptoms (and what usually causes them)

• Won’t start or starts then dies: stale fuel, dirty air filter, fouled spark plug, or a loose/disconnected spark plug wire
• Loss of drive or slow drive speed: drive control out of adjustment, worn drive belt, or debris in the drive wheel area
• Excessive vibration: bent/worn blade, loose blade bolt, or a damaged blade adapter
• Poor cut or uneven cut: dull/bent blade, deck packed with grass, or wheels set at different heights
• Hard to pull starter rope: operator presence control not held, blade dragging in grass, or internal engine issue

For model-specific troubleshooting steps and maintenance intervals, use the 917370930 owner’s manual.

Quick checks we recommend first (fast, no parts needed)

• Drain old gas and refill with fresh unleaded fuel (use fuel within about 30 days).
• Check engine oil level before each use; low oil can cause hard starting and poor performance.
• Clean the underside of the deck after mowing; packed grass can cause power loss and uneven cutting.
• Verify all four wheels are set to the same cutting height.
• Inspect for loose fasteners, especially around the blade and handle.
