Craftsman 917388420 lawn mower Parts

Yes, you can pull the Craftsman 917388420 self-propelled mower backward, but we recommend doing it only when necessary. When backing up, keep the drive disengaged, look down and behind you, and move slowly to stay in control and avoid contact with the blade area.

How to back up safely

• Release the self-propel drive control (so the wheels freewheel instead of trying to drive).
• Keep the operator presence control bar held as required for operation; if you need to step away, shut the engine off.
• Always look down and behind before and while moving backward.
• Back up slowly and only as far as needed.
• Keep hands and feet away from the deck and discharge opening.

What to do if it feels hard to pull backward

If the mower resists when you pull it backward, the drive may still be partially engaged or the wheels may be binding.

Symptom	Most common cause	What we recommend
Wheels “lock” or drag in reverse	Drive not fully disengaged	Fully release the drive control and try again
Grinding or clicking	Debris in wheel/drive area	Shut off engine, remove spark plug wire, clear debris
Pull cord suddenly becomes hard to pull after backing up	Blade or engine binding	Stop immediately and inspect under deck before restarting

Why it matters

Backing up increases the chance of slips and puts your feet closer to the deck. The manual specifically advises not pulling the mower backward unless absolutely necessary, and to look down and behind while moving backward. Use the safety guidance in the 917388420 owner's manual.

For a Craftsman 6.75 (675 Series) walk-behind mower like the one covered on this parts page, the model number is 917.388420 (often written without the dot as 917388420). You’ll find it on the model/serial decal on the rear of the mower housing; confirm it against the 917388420 owner’s manual.

Where to find the model number on the mower

Look for the identification decal before ordering parts or referencing specs.

• Check the rear of the lawn mower housing for the decal
• Record both the model number and serial number
• Write down the date of purchase for maintenance and service records
• Use the model number to match the correct blade, cable, and handle parts

Model number formats you may see

Both formats refer to the same Craftsman mower.

You might see it as	It means
917.388420	Standard manual/label format
917388420	Common online/parts lookup format

Why it matters

Craftsman “6.75” or “675 Series” describes the engine family, not the exact mower build. The model number (917.388420) is what ensures the right fit for parts like the lawn mower blade 532406712 and lawn mower zone control cable 532183281.

For your Craftsman lawn mower model 917388420, use fresh, clean regular unleaded gasoline; most owners use E10 (up to 10% ethanol). Avoid old or contaminated fuel because it commonly causes hard starting, surging, and stalling. For fuel and safety details, follow the 917388420 owner's manual.

What to use (and what to avoid)

• Use fresh regular unleaded from a clean gas can.
• E10 is commonly used; keep it fresh and tightly sealed.
• Avoid stale fuel (especially fuel stored for weeks or months).
• Avoid fuel contaminated with water, rust, or dirt.
• Avoid mixing oil into the gas; this mower uses a 4-cycle engine (oil goes in the crankcase, not the fuel).

Quick fuel checklist before you fill up

• Shut the engine off and let hot parts cool.
• Wipe dirt away from the fuel cap area so debris does not fall into the tank.
• Use a clean, non-rusting container; replace rusty cans.
• Add fuel stabilizer if the mower will sit unused.
• Tighten the fuel cap securely after filling.

If the mower will not start after fueling

Stale or contaminated gasoline is a top cause of “won’t start” on this model. If you suspect bad fuel:

• Drain the tank and refill with fresh gasoline.
• Check the spark plug connection.
• Inspect for a loose blade or a worn blade adapter (a loose blade can affect starting and safety).

Symptom	Common fuel-related cause	What to do
Won’t start	Out of fuel or stale fuel	Refill with fresh gasoline
Starts then dies	Water in fuel	Drain and refill with fresh gasoline
Runs rough	Dirt/rust in fuel	Replace gas can, use clean fuel

Why it matters

Fresh fuel protects the carburetor and fuel system, improves starting, and reduces deposits that shorten engine life. It also helps prevent troubleshooting issues that look like ignition or compression problems but are really fuel quality.

For Craftsman walk-behind mowers like model 917388420, the model number is printed on a decal on the rear of the lawn mower housing. Once you find that decal, match the model number exactly (all digits) to identify the correct parts list and manual.

Where to look on a walk-behind mower

Check these common spots first:

• Rear of the mower deck or housing (most common for this model)
• Near the engine mounting area on the deck
• On the handle support/frame area near the rear wheels
• On a label that also lists the serial number

For this Craftsman mower, the manual specifies the model and serial numbers are on a decal on the rear of the lawn mower housing; use the 917388420 owner's manual to confirm the label location and what the decal looks like.

What to write down (and why)

Record both the model number and serial number from the decal.

• Model number: identifies the correct parts diagrams and part compatibility
• Serial number: helps confirm production variation when parts changed mid-run
• Date of purchase (if known): useful for maintenance planning and service history

Quick ID checklist

• Model number is numbers only for this unit (example: 917388420)
• Copy it exactly; do not add spaces or punctuation
• If the decal is worn, clean the area and use a flashlight at an angle to read it

Why it matters

Using the exact model number prevents ordering the wrong blade, cable, or handle hardware. For example, parts like the lawn mower blade 532406712 and blade adapter 532418373 are model-matched; the wrong version can cause poor cutting, vibration, or fit issues.

If you see this	It usually means	What to do
Decal says 917.388420	Same model format	Use 917388420 when searching
Decal missing or unreadable	Wear, corrosion, or repaint	Check other label locations and compare parts diagrams
Model matches but parts differ	Serial-based variation	Use serial number to confirm the correct part
