Craftsman 917375450 lawn mower Parts

For your Craftsman walk-behind mower, the model number is printed on the mower’s ID label (often called the model tag) mounted on the deck housing or rear of the mower. For this parts page, the correct model number format looks like 917.375450 (often shown without the dot as 917375450).

Check these common ID-label locations first (wipe off grass and dirt so you can read it clearly):

• On top of the mower deck near the engine
• On the rear of the deck, behind the engine
• Near the rear discharge area or bagging opening
• On the handle bracket area near the deck
• Under a flap or cover near the deck edge

For diagrams and label examples that match your mower, use the 917375450 owner's manual.

Record the information exactly as shown on the tag:

• Model number (example: 917.375450)
• Product number (if listed)
• Serial number
• Engine model/type/code (engine parts often use this)

Craftsman walk-behind mowers can look identical across multiple model numbers, but use different drive belts, wheels, and controls. Using the exact model number helps us match the correct diagrams and parts, like the lawn mower ground drive belt 532196853 when you’re troubleshooting self-propel issues.

The model number is 917375450. On Craftsman walk-behind mowers, the model number is the primary identifier we use to match the correct parts, diagrams, and maintenance information for your exact mower; see the 917375450 owner's manual for the model ID locations.

Most Craftsman walk-behind mowers show the model number on a label or stamped plate. Check these common spots:

• Rear of the deck near the discharge opening
• Top of the deck near the engine mounting area
• Back of the mower housing near the height adjusters
• Handle support/bracket area
• Under the rear flap or near the bagger mounting points

When you locate the ID label, record these details:

• Model number: 917375450
• Product name/brand: Craftsman walk-behind mower
• Any additional numbers on the tag (often a serial or production code)
• Engine brand and engine model (helpful for tune-up parts)

Craftsman model numbers can look similar across different mower versions. Using 917375450 ensures you get the right walk-behind mower parts such as the lawn mower blade 580244002, drive components, and deck hardware.

For a Craftsman walk-behind mower model 917375450, the serial number can often tell you the build date, but the format depends on who manufactured the mower and the engine. We use the serial tag on the mower (and the engine code on the engine) to pinpoint the year and sometimes the exact week or day.

Check these common locations:

• On the mower deck, usually near the rear wheel area or discharge opening
• On the handle bracket or rear skirt area
• On the engine itself (engine model/type/code label or stamped code)
• In the Craftsman 917375450 owner's manual under identification or service information

Serial number formats vary, so we recommend checking both the mower serial and the engine code.

• If you see a clear date pattern like MMDDYY or YYMMDD, that is typically the manufacture date.
• If the serial starts with a year/week style code, the first digits often represent the year and production week.
• If the mower serial is unclear, the engine code is often the fastest way to date the machine because engines commonly include a manufacture date in the code.

• Record the full model number (917375450) and the full serial number exactly as shown
• Record the engine code (photo helps)
• Decode the engine date first, then compare it to the mower serial date code
• If dates differ, use the newer of the two as the likely final assembly timeframe

Knowing the manufacture date helps us match the correct Craftsman parts and diagrams for wear items like the blade, drive system, and controls, especially when a model has mid-year production changes.

The 754-05025 belt is commonly sold as a 54-inch deck belt (about 54 inches effective length) on many riding mower deck applications. For your Craftsman 917375450 walk-behind mower, we use the model’s parts list in the 917375450 owner's manual to confirm the correct belt and size before ordering.

Walk-behind mowers like the Craftsman 917375450 typically use a ground drive belt (self-propel belt), not a “deck belt.” If you install the wrong belt length, the mower can slip, squeal, or not self-propel.

Check these items on your mower:

• Where the belt is used: self-propel drive vs blade/deck drive
• The belt marking: 754-05025 vs a similar suffix (A, B, etc.)
• Pulley layout: idler pulley and transmission pulley positions
• Belt width profile: fractional-horsepower style belts are common on walk-behinds
• Whether the belt is stretched, glazed, or cracked (a worn belt can “measure” longer)

Belt listings often show one of these measurements; sellers do not always label them the same way.

Before replacing parts, we check the basics that cause “no drive” symptoms:

• Inspect belt for glazing, cracks, or missing chunks
• Verify the drive cable has tension and returns freely
• Check the drive pulley and idler for wobble or binding
• Look for debris wrapped around the transmission input or wheels
• Confirm the belt is routed correctly per the 917375450 owner's manual

If you need the self-propel belt for this model, the correct model-matched option is the lawn mower ground drive belt 532196853.

A belt that is even slightly off in length or profile changes pulley engagement. That leads to poor traction, premature belt wear, and extra strain on the transmission and idler system.

On a Craftsman walk-behind mower like model 917375450, the serial number format varies by manufacturer and production run, so we use the ID label plus the model number to interpret it correctly. Start by locating the serial tag, then match its pattern using the 917375450 owner's manual.

Most Craftsman walk-behind mowers place the model and serial information on a sticker or stamped tag in one of these spots:

• Rear of the mower deck (near the discharge opening)
• Top of the deck near the engine mounting area
• Back panel near the bagger opening or rear skirt
• Handle bracket area (left or right side)

Craftsman equipment has been built by different manufacturers over the years, so serial numbers are not one universal code. These are the most common ways they’re structured:

• Date-coded serials: a section of the serial indicates month, day, and year
• Julian date serials: a 3-digit day-of-year plus a year digit
• Production/sequence serials: no readable date; it’s a build sequence used for parts tracking

Reading the serial number correctly helps us match the right Craftsman parts for your 917375450 mower, especially for items that change by production run (drive system hardware, deck components, and controls).

When ordering or troubleshooting, record both:

• Model number: 917375450
• Full serial number exactly as printed

Common problems on Craftsman walk-behind mowers like model 917375450 usually fall into a few buckets: hard starting, poor cutting, excessive vibration, and self-propel/drive issues. Most fixes start with basic maintenance checks, then move to inspecting wear parts and linkages.

• Won’t start or starts then dies: stale fuel, dirty carburetor, fouled spark plug, clogged air filter
• Rough running or surging: fuel restriction, dirty carburetor jets, vacuum leak, old gas
• Cuts unevenly or leaves strips: dull/bent blade, deck packed with grass, cutting height mis-set
• Excessive vibration: bent blade, loose blade bolt, damaged blade adapter (if equipped)
• Self-propel won’t move or slips: stretched/worn drive belt, cable out of adjustment, worn transmission components
• Grass clumps or poor bagging: wet grass, clogged deck, damaged deflector or mulching door

1. Fuel: drain old gas and refill with fresh fuel (especially after storage).
2. Spark plug: inspect and replace if fouled or worn.
3. Air filter: clean or replace if dirty.
4. Blade and deck: clean the underside of the deck and inspect the blade.
5. Drive system (self-propel models): check belt condition and cable tension.

These are frequent “wear item” culprits on Craftsman 917375450 mowers:

Catching these problems early prevents bigger failures (like a damaged transmission or deck) and improves cut quality, bagging performance, and engine life.

Craftsman walk-behind mowers (including model 917375450) are commonly equipped with engines supplied by major small-engine manufacturers; the most common supplier is Briggs & Stratton, with some Craftsman models using Kohler or Kawasaki engines depending on the specific mower series and production run. For your exact engine identification, we use the engine model and type codes shown in the 917375450 owner's manual.

Use these quick checks on the mower itself (no disassembly needed):

• Look for the engine shroud decal (usually says Briggs & Stratton, Kohler, or Kawasaki).
• Check the valve cover or recoil starter housing for a brand badge.
• Find the engine ID tag (often near the muffler, flywheel cover, or above the spark plug).
• Record the engine model, type, and code (or spec number) exactly as printed.
• Match that information to the engine section in the 917375450 owner's manual.

Craftsman is the mower brand, but many tune-up and repair parts are engine-specific. The engine brand and model determine the correct spark plug, air filter, carburetor parts, and governor settings.

If you are troubleshooting drive or cutting performance, these parts are tied to the mower platform (not the engine brand):

• Lawn mower blade 580244002 for cutting quality issues (uneven cut, tearing).
• Lawn mower ground drive belt 532196853 for self-propel problems (slipping or no drive).
• Drive cable 532447570 if the drive control feels loose or does not engage.

• For blade service, we follow the steps in how to sharpen a lawn mower blade.

Ordering by the correct engine brand and engine model prevents wrong tune-up parts, hard starting, and poor performance. Ordering by the correct mower model (917375450) prevents fit issues with deck, wheels, and drive components.

For a Craftsman walk-behind mower like model 917375450, repairing is cheaper when the fix is a normal wear item (blade, belt, cable). Replace the mower when a major failure pushes the repair estimate to about 50% or more of the cost of a comparable new mower.

Use this simple decision check before buying parts:

• Repair if the mower runs well and the problem is a wear part or adjustment
• Repair if the estimate is under ~50% of replacement cost
• Replace if the engine has low compression, heavy smoke, or severe internal damage
• Replace if the drive system needs multiple major components at once (belt plus transmission plus wheels)
• Replace if the deck is cracked or badly rusted through (structural damage)

These are typical, cost-effective fixes on self-propelled walk-behind mowers:

• Replace a worn drive belt such as the lawn mower ground drive belt 532196853
• Replace a stretched or sticking drive cable such as the drive cable 532447570
• Replace a bent or dull blade such as the lawn mower blade 580244002
• Replace a damaged discharge component such as the lawn mower clipping deflector 532426129

Choosing repair vs. replace the right way saves money and time. On model 917375450, many drive and cutting problems trace back to serviceable parts, but major engine or transmission failures can turn into a high-cost repair fast.

• Price a comparable new mower first (so you have a real replacement number)
• List the failed parts and add them up (parts plus any shop labor)
• Check the maintenance and adjustment steps in the 917375450 owner's manual
• If the mower “won’t move,” use the lawn mower wont move troubleshooting video motion drive failure guide to narrow it down before ordering parts
