Craftsman 917371822 lawn mower Parts

For the Craftsman 917371822 gas walk-behind mower, we use fresh, regular unleaded gasoline and avoid higher-ethanol fuels (such as E15 or E85) that are not intended for most small engines. Use clean fuel and store it properly to prevent hard starting and poor performance; see the 917371822 owner's manual for model-specific operating and safety guidance.

• Use fresh, regular unleaded gasoline from a busy station (helps reduce stale fuel issues).
• Avoid E15 and E85; higher ethanol blends can cause starting and running problems in small engines.
• Keep the gas can clean and sealed to prevent water contamination.
• Buy only what you will use in about 30 days.
• If the mower will sit, add fuel stabilizer and run the engine briefly to circulate treated fuel.

Old fuel is one of the most common reasons a walk-behind mower will not start after sitting.

• For short storage (a few weeks): keep the tank nearly full and use stabilizer.
• For seasonal storage: follow the storage steps in the 917371822 owner's manual.
• If fuel smells sour or looks dark, drain and replace it with fresh gas.

Using the right gasoline helps protect the carburetor, fuel lines, and seals, and it reduces issues like surging, stalling, and hard starting. Fresh fuel also supports consistent power under load when cutting thicker grass.

For a Craftsman walk-behind mower like model 917371822, the model number is typically printed on a product label on the mower deck (often near the rear discharge area) or on the rear housing behind the engine. Use the model number to match the correct parts list and diagrams in the 917371822 owner's manual.

Check these common label locations first:

• Top of the mower deck, near the engine mounting area
• Rear of the deck, close to the discharge chute or rear door
• Back of the mower housing, behind the engine
• Near the handle mounting brackets on the deck
• On a sticker or metal tag that also lists a serial number

The manual identifies this mower as Model No. 917.371822 (you may see it with or without the dot). To avoid ordering the wrong parts:

• Copy the full model number exactly as shown
• Look for a second line with a serial number (helpful for production variations)
• Clean the label gently if it is covered with grass or oil
• Take a clear photo before the label fades further

Craftsman walk-behind mowers often share similar looks across multiple model numbers, but parts like the drive control, blade brake and clutch, and wheel hardware can differ. Using 917371822 keeps your repair accurate and safe.

Hydrostatic transmission repairs are typically a riding-mower cost; Craftsman walk-behind model 917371822 normally uses a belt-and-pulley drive system instead of a hydrostatic transmission. If your mower will not self-propel, the repair cost is usually much lower and often involves a belt, cable, or drive control adjustment described in the owner's manual.

Hydrostatic transmission work (common on riding mowers) is expensive because the transmission is a sealed, high-precision assembly.

Before assuming a major drivetrain failure, we recommend checking the common self-propelled items first:

• Inspect the ground drive belt for glazing, cracking, or stretching.
• Check the drive control cable for slack, kinks, or a broken end.
• Confirm the drive control bar fully engages and returns smoothly.
• Look for a damaged pulley or binding wheel/axle.
• Check for missing retaining hardware on the drive components.

Model-relevant parts that often relate to “won’t move” symptoms include the lawn mower drive control assembly 583297901 and the belt.rgd.vs 532406580.

A hydrostatic transmission quote can sound alarming, but it usually does not apply to walk-behind mowers. On model 917371822, a simple belt or control issue can mimic “transmission” trouble and is faster and cheaper to fix.

Use a professional service shop if:

• The drive system binds, smokes, or makes grinding noises.
• The mower surges forward unexpectedly when drive is engaged.
• You find bent shafts, cracked housings, or repeated belt failures.

For adjustment points and inspection locations, follow the Service and Adjustments guidance in the owner's manual.

A Craftsman self-propelled mower like model 917371822 usually pulls to one side when one drive wheel is not driving evenly. The most common causes are a slipping drive system, a sticking wheel/axle component, or a drive control that needs adjustment; use the owner's manual to match the control and adjustment points on your mower.

• Make sure both rear wheels spin freely with the engine off.
• Clean packed grass and debris from around the wheels and under the deck.
• Confirm the drive control lever is being pulled evenly and fully to the handle.
• If the mower will not roll backward after releasing drive, push it forward slightly to disengage the drive wheels (this is normal behavior noted in the manual).
• Inspect the wheels for missing retainers or worn drive parts.

Your 917371822 uses a drive control lever to engage forward motion. Over time, the drive control can feel “loose” and reduce drive tension, which can make one side lag and cause pulling.

Typical symptoms and what they point to:

If you find looseness, wear, or missing hardware at a wheel, these parts are often involved:

• Drive pawl 532404845 (helps the wheel drive consistently)
• Lawn mower wheel dust cover 581840401 (keeps debris out of the wheel area)
• Lawn mower e-ring 812000058 (retains wheel/axle components)
• Lawn & garden equipment nut 532409149 (wheel/axle fastening hardware)

When one drive wheel is doing more work than the other, the mower constantly “steers” itself. Fixing the uneven drive reduces operator fatigue, improves cut quality, and helps prevent premature wear on the drive belt, pulleys, and wheel components.

A 42-inch Craftsman deck belt size depends on the exact tractor model, not the brand alone. For your Craftsman walk-behind mower model 917371822, the drive belt listed in the parts breakdown is a V-belt (not a 42-inch deck belt); use the belt specified in the owner's manual and match it to the correct replacement part.

A “42-inch belt” question usually refers to a 42-inch cutting deck on a riding mower. Model 917371822 is a walk-behind rotary mower, so it uses a ground drive belt for self-propel, not a deck belt.

• 42-inch deck belt: riding mower only (belt drives the blade deck)
• Walk-behind drive belt: powers the transmission/wheels
• Belt size is not universal across Craftsman models
• The safest match is always by model number and belt part listing

In the model 917371822 drive system breakdown, the belt is identified as V-belt.

For this model, the belt is shown as V-belt in the drive assembly list; the corresponding replacement on our parts list is belt.rgd.vs 532406580.

• Confirm the mower model is 917371822 (walk-behind)
• Compare the old belt’s wear pattern and routing before removal
• Inspect belt keepers and pulleys for bending or rubbing
• If the mower “won’t move,” check the return spring and drive control cable adjustment
• Replace any missing retaining clips or hardware during reassembly

Using a 42-inch deck belt size on the wrong mower type leads to poor traction, slipping, or a belt that will not route correctly. Matching the belt to 917371822 keeps the self-propel drive working and prevents premature belt failure.
