Craftsman 917378200 lawn mower Parts

On Craftsman walk-behind mower model 917378200, the serial number is primarily used to identify your exact unit for parts and service; the most reliable first step is to find the serial decal on the rear of the mower housing and record it exactly as shown in the 917378200 owner's manual.

Where to find the serial number (917378200)

We see the serial number location called out for this model on a decal at the rear of the mower housing.

• Look on the rear of the lawn mower housing (near the deck, behind the engine area)
• Write down both the model number and serial number
• Record the date of purchase if you still have it
• Take a clear photo of the decal before it gets worn or dirty

How to interpret the serial number

Craftsman serial-number formats vary by mower family and production run. Many Craftsman mowers use a date-coded serial number (often read as month, day, year in the first six digits), but the exact pattern depends on the label format printed on your mower.

Common problems we see on the Craftsman 917378200 walk-behind mower are hard starting, loss of power, poor cut quality, excessive vibration, starter rope that is hard to pull, and self-propel drive issues. Most fixes start with basic maintenance and a quick inspection using the 917378200 owner's manual.

Most common symptoms and what usually causes them

• Won’t start or starts then dies: old fuel, dirty carburetor, fouled spark plug, dirty air filter
• Loss of power: grass buildup under the deck, cutting height too low, dirty air filter, oil level issues
• Poor cut or uneven cut: dull, bent, or loose blade; uneven wheel height settings; deck packed with clippings
• Excessive vibration: worn/bent/loose blade; impact damage (possible crankshaft issue)
• Starter rope hard to pull: control bar not held to the handle; blade dragging in grass; damaged blade adapter
• Self-propel won’t move or slows: worn belt, belt off pulley, worn/broken drive cable

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

1. Make it safe: disconnect the spark plug wire before working near the blade.
2. Check the control bar: hold it against the upper handle before pulling the starter rope.
3. Look under the deck: remove packed grass and debris (a common power and cut-quality killer).
4. Inspect the blade and hardware: tighten a loose blade; replace a bent or damaged blade.
5. Check drive wheels: if they do not turn freely, clean debris from the wheel area.
