Craftsman 9172736404 lawn tractor Parts

Craftsman engines are made by several manufacturers depending on the specific mower or tractor model and production year. For Craftsman lawn and garden equipment, the most common engine suppliers are Briggs & Stratton, Kohler, and Kawasaki; your Craftsman 9172736404 uses an 18.5 HP gasoline engine (see the owner's manual for the exact engine identification details).

How to identify the engine maker on model 9172736404

Use these quick checks to confirm the engine manufacturer and engine model family:

• Look for the engine ID label on the engine shroud, valve cover, or blower housing
• Record the engine model, type, and code/spec numbers (often three separate fields)
• Check the tractor’s product identification label under the seat or on the frame
• Match those numbers to the engine section in the owner's manual
• If the label is missing, use the tractor model number 9172736404 to cross-reference the correct engine parts list

What “Craftsman engine” usually means

Craftsman is the equipment brand; the engine is typically sourced from a major small-engine maker. On riding lawn tractors, that sourcing can vary by:

• Deck size and configuration (this model is a 42-inch mower deck)
• Horsepower rating (this model is listed as 18.5 HP)
• Emissions family and production run
• Replacement engine history (some tractors have had engine swaps)

Common engine suppliers (quick comparison)

Engine supplier	Where you’ll see it most often	What to look for on the label
Briggs & Stratton	Many Craftsman riding mowers	Model, type, code
Kohler	Some mid to higher spec tractors	Model, spec, serial
Kawasaki	Some premium tractors	Model, spec, serial

Why it matters

Knowing the engine maker helps you buy the right tune-up and starting-system parts (spark plug, air filter, fuel filter, starter components) and follow the correct maintenance schedule. It also speeds up troubleshooting when the tractor won’t crank or won’t start.

If your tractor clicks but will not crank, a common fix path is checking the battery connections and the starter solenoid; the solenoid with brass plunger 532146154 is one of the starting-system parts available for this model.

On a Craftsman lawn tractor like model 9172736404, the model number does not contain the build year; the year is determined from the serial number/date code on the tractor’s ID label. Use the date code format shown on your label, then confirm the label location and decoding notes in the owner's manual.

Where to find the serial number/date code

Most Craftsman riding mowers and lawn tractors place the ID label in one of these spots:

• Under the seat pan or on the seat deck
• On the rear fender pan near the seat
• On the frame rail near the engine
• Near the rear axle area
• Under the hood on the chassis

How to decode the year from the serial number

Many Craftsman-built riding mower serial/date codes use a MMDDYY style date code (month, day, year). If your label shows six digits that match this pattern, decode it like this:

• First 2 digits: month (01 to 12)
• Next 2 digits: day (01 to 31)
• Last 2 digits: year (00 to 99)

Quick examples

Date code	Decodes to	Build year
072811	July 28, 2011	2011
031905	March 19, 2005	2005
112320	November 23, 2020	2020

If your label does not match MMDDYY

Some labels use a different format (letters mixed with numbers, or more than six digits). In that case, use these checks:

• Look for a separate line that says “Date”, “MFG Date”, or similar
• Compare any 2-digit year to the tractor’s feature set (deck size, transmission type, safety switch style)
• Use the identification and maintenance sections in the owner's manual to confirm you are reading the correct label

Why it matters

Knowing the correct build year helps us match the right parts and diagrams for your 9172736404, especially wear items like mower deck blades, belts, and mandrel components.

For Craftsman lawn tractor model 9172736404, the fastest way to find the right replacement part is to match your model number to the parts diagrams and parts list, then confirm the part name and identifier before ordering. Your owner's manual also helps you identify assemblies and maintenance items.

Step-by-step: find the correct part for your 9172736404

• Locate the model number tag on the tractor frame (then match it to 9172736404).
• Use the parts diagrams to find the exact assembly (mower deck, steering, electrical, drivetrain).
• Click into the assembly and match the callout number to the parts list.
• Confirm the part by part name and part ID (not just a description).
• Compare what you see on your tractor to the diagram (mounting holes, connectors, belt routing).
• Order the part once the ID matches.

Common parts customers look for on this model

If you are stocking up on wear items for the 42-inch deck, these are common starting points:

What you are replacing	What to match	Example part on this model page
Mower blade	Deck size and blade style	Lawn tractor 42-in deck high-lift blade 532138971
Mulching blade	Deck size and mulching profile	Husqvarna lawn tractor mulching blade, 21-in 532134149
Blade drive belt	Length and width	Craftsman lawn tractor blade drive belt, 5/8 x 97-2/5-in 532174883
PTO engagement switch	Connector style and mounting	Switch.pto 582107601

Tips to avoid ordering the wrong part

• Match by model number first, then by part ID.
• If a part has multiple versions, use the diagram notes and your tractor’s configuration.
• For deck parts, confirm you have the 42-inch mower deck (this model is listed as 42-inch in the manual).
• For electrical parts, compare plug shape and wire count before ordering.

Why it matters

Riding mower parts often look similar across Craftsman and Husqvarna-built tractors, but small differences in deck hardware, belt routing, and electrical connectors can cause fit issues. Using the model-specific diagrams and the owner's manual prevents mismatches and saves time.

Replacing the engine on a Craftsman front-engine lawn tractor like model 9172736404 typically costs $900 to $2,500 installed. Most of that total is the engine itself plus about 4 to 8 hours of labor, fluids, and any worn drive components found during the swap. Use the 9172736404 owner's manual for safety steps before any engine work.

What makes the price go up or down

• Engine type and source: new engines cost more than rebuilt or used
• Labor time: engine swaps commonly run 4 to 8 hours on riding tractors
• Add-on parts: belts, pulleys, wiring, and battery cables often need attention
• Fluids and tune-up items: oil, filter (if equipped), fuel filter, spark plug
• Deck removal: removing and reinstalling a 42-inch deck can add time

Typical cost breakdown

Cost item	Typical range	Notes
Engine (part)	$600 to $1,800	Biggest variable; depends on horsepower and configuration
Labor	$300 to $900	Based on 4 to 8 hours and local shop rates
Fluids and small parts	$25 to $150	Oil, filter, clamps, hardware
Related repairs (if needed)	$50 to $600	Belts, electrical, PTO, deck components

Check these before paying for an engine

Many “bad engine” symptoms are actually starting or safety-interlock problems. The troubleshooting chart in the manual points to checks like battery condition, terminals, fuses, wiring, ignition switch, and the starter solenoid.

• Battery fully charged and terminals clean
• Brake pedal fully depressed and PTO disengaged
• Fuse and wiring connections in good condition
• Ignition switch and solenoid operating correctly

If the tractor clicks but will not crank, a common fix is a failed solenoid; this model’s parts list includes the solenoid with brass plunger 532146154.

Why it matters

An engine replacement is one of the highest-cost repairs on a riding mower. Confirming the problem first can turn a major expense into a smaller electrical or fuel-system repair.
