Craftsman 917377532 rotary lawn mower Parts

For a Craftsman walk-behind mower, we read the model number from the identification decal on the mower housing; for model 917.377532, the model and serial numbers are on a decal attached to the rear of the lawn mower housing. Use that full model number to match the correct parts list and owner’s manual.

Check these common spots first:

• Rear of the mower deck (housing), on a decal (most common)
• Near the rear discharge door area
• On the back plate area behind the handle mounts
• On the handle bracket area (less common)

For diagrams and the exact identification location callouts, use the owner's manual.

On this Craftsman mower, the model number is typically shown with a dot format (example: 917.377532). When ordering parts online, you can enter it with or without the dot (example: 917377532).

Using the exact model number prevents ordering the wrong blade, belt, wheel, or control parts. For example, this model’s parts list includes items like the lawn mower mulching blade 532406713 and the belt 532157769, which must match your deck size and drive system.

Hydrostatic transmission repairs are typically a riding mower cost; your Craftsman 917377532 is a 22-inch walk-behind rotary mower and normally uses a belt-and-gear drive system instead of a hydrostatic transmission. For this mower, “won’t move” repairs usually involve the drive belt, pulleys, or drive control, which are far less expensive than hydrostatic replacement. See the 917377532 owner's manual for the drive system layout and service checks.

Hydrostatic transmissions are most common on riding mowers; costs vary widely by mower type and whether you replace the whole transaxle.

• Walk-behind self-propelled mower (like 917377532): usually a belt, control cable/assembly, or gear issue
• Riding mower with hydrostatic drive: higher parts cost and more labor time
• If the mower moves weakly: belt wear, pulley wear, or drive control adjustment is common
• If the mower will not move at all: belt off/broken, damaged drive gear, or failed drive control is common

If your Craftsman 917377532 is self-propelled and the wheels are not pulling, these parts are frequent suspects:

• Belt 532157769 (worn, stretched, or broken)
• Control 532184588 (drive control assembly not engaging)
• Walk-behind lawn mower engine pulley 532084596 (worn pulley can slip)
• Lawn mower drive pinion gear 532137054 (stripped gear teeth)
• Drive cover 583720801 (damage or debris buildup affecting the drive area)

A hydrostatic transmission quote can look alarming, but it usually does not apply to a walk-behind mower like the Craftsman 917377532. Checking the belt, pulley, and drive control first helps you avoid unnecessary repairs and gets the self-propel drive working again faster.

Craftsman model 917377532 is identified by its serial number, not by the model number alone. On this mower, the model and serial label is on a decal attached to the rear of the mower housing; use that serial number to determine the manufacturing date (see the owner's manual).

1. Locate the model/serial decal on the rear of the mower housing.
2. Write down the serial number exactly as shown.
3. Use the serial number to decode the manufacture date (the model number 917377532 stays the same across production runs).

• Look for a decal that lists MODEL NO. 917.377532 and a SERIAL NO.
• Clean the area so all digits are readable.
• Record the serial number before ordering parts or doing repairs.

The model number 917377532 identifies the Craftsman rotary lawn mower design and parts breakdown, but it does not uniquely identify the build date. The serial number is what ties your mower to a specific production period, which matters for matching items like the drive system and hardware.

If you are ordering parts, confirming the serial number first helps avoid mismatches.

The correct manufacture date and configuration help ensure you get the right replacement parts the first time, especially for drive components, wheels, and control assemblies.

Common problems on the Craftsman 917377532 gas walk-behind mower include no-start conditions (stale fuel, dirty air filter, disconnected spark plug wire, bad spark plug), loss of power from heavy grass or deck buildup, and uneven cutting from a worn or loose blade or uneven wheel height settings. See the owner's manual troubleshooting chart for model-specific checks.

• Engine will not start: dirty air filter, out of fuel, stale fuel, water in fuel, spark plug wire disconnected, bad spark plug, control bar not held down
• Loss of power: cutting too much grass at once, grass and debris buildup under the deck, dirty air filter, walking speed too fast
• Poor cut or uneven cut: worn or bent blade, loose blade hardware, wheel heights set unevenly, deck packed with clippings
• Self-propelled issues (if equipped): worn drive belt, damaged drive control, worn drive gears

1. Confirm the control bar is held against the handle while starting (operator presence control must be engaged).
2. Check fuel quality: drain and refill if fuel is stale; water-contaminated fuel also needs to be drained.
3. Inspect the air filter: clean or replace if dirty.
4. Check ignition basics: make sure the spark plug wire is firmly connected; replace the spark plug if fouled.
5. Look under the deck (engine off, spark plug wire removed): remove grass buildup that can drag the blade and reduce power.
6. Inspect the blade and mounting: a loose blade bolt or a broken blade adapter can cause starting and cutting problems.

Most “won’t start” and “loses power” complaints come down to airflow (air filter), fuel condition (stale or water-contaminated gas), or drag from a packed mower deck. Fixing those basics first prevents unnecessary parts replacement and helps protect the engine and blade system.

The Craftsman 917377532 is a gas walk-behind rotary lawn mower, not a stand-on mower, so it is not priced as a stand-on unit. For this model, we focus on replacement parts and maintenance; use the owner's manual to confirm features and configuration.

Stand-on mower pricing varies widely by brand, deck size, and engine; most new stand-on mowers typically run several thousand dollars. If you are shopping for a mower, make sure you are comparing the same mower type (stand-on vs walk-behind) and deck size.

Common replacement parts for this Craftsman walk-behind mower include:

• Lawn mower mulching blade 532406713 for cutting and mulching performance
• Belt 532157769 if the self-propel drive slips or stops pulling
• Lawn mower wheel 582976701 if a wheel is cracked, wobbly, or won’t roll smoothly
• Lawn mower blade adapter 581547901 if the blade won’t tighten securely or the adapter is worn
• Husqvarna lawn mower height adjuster knob 532701037 if height settings won’t hold

Pricing confusion usually comes from mixing mower categories. Matching the correct equipment type to the model number helps you avoid ordering the wrong parts and helps you compare costs accurately.
