Craftsman 917275632 tractor Parts

The most common issues we see on the Craftsman 917275632 front-engine lawn tractor involve the mower deck (poor cut quality, vibration, belt problems), starting and electrical no-starts, and steering or drive wear. Using the correct maintenance intervals and the right-fit replacement parts prevents repeat failures; see the 917275632 owner's manual for model-specific checks.

Common problems and what they usually point to

• Uneven cut or missed strips: dull/bent blades, deck not leveled, worn mandrel bearings
• Excessive vibration: damaged blade, loose blade hardware, failing mandrel assembly
• Blades will not engage: PTO switch issue, clutch problem, belt off or stretched
• Mower deck belt keeps coming off: worn idler pulley, weak idler spring, misrouted belt
• Clicks but will not crank: weak battery connections, bad solenoid, safety switch issue
• No power or intermittent start: ignition switch, key, or harness connection problems

Quick checks we recommend first (fast and safe)

1. Park on level ground, set parking brake, remove the key, and disconnect the spark plug wire.
2. Inspect blades for bends, cracks, and heavy nicks; replace as a set when needed.
3. Check belt routing and tension; look for glazing, fraying, or a rolled edge.
4. Spin idler pulleys by hand; roughness or wobble means replacement.
5. Confirm the PTO switch and ignition switch feel positive (not loose or sticky).

Parts that commonly solve these symptoms

Symptom	Likely wear item	Example part for this model
Belt slips, squeals, or jumps	Deck belt	Craftsman lawn tractor blade drive belt, 5/8 x 97-2/5-in 532174883
Vibration, noisy deck spindle	Mandrel/spindle	Husqvarna lawn tractor mandrel assembly 532130794
Belt won’t stay tensioned	Idler pulley or spring	Lawn tractor blade idler pulley 532139245 and lawn tractor blade idler spring 532169022
No crank, single click	Starter solenoid	Solenoid with brass plunger 532146154
No start, intermittent power	Ignition switch/key	Lawn tractor ignition switch 532193350 and molded ignition key 532140403

Why it matters

Deck and starting issues often share the same root cause: normal wear that changes alignment, tension, or electrical contact. Fixing the worn component (belt, idler, mandrel, switch) restores safe operation and protects the engine, electric clutch, and deck housing.

For the Craftsman front-engine lawn tractor with a 42-inch mower deck shown here, the model number is 917.275632 (often written without the dot as 917275632). You can confirm the exact model and deck details in the 917275632 owner's manual.

Where to find the model number on the tractor

We recommend matching the model number from the ID label to ensure you get the right parts (blades, belts, ignition parts, and deck hardware).

• Check under the seat area or on the rear fender pan near the seat
• Look on the frame rail near the engine compartment
• Check near the transaxle area on the rear frame
• Write down the full model number exactly as shown (including any dots)

Why the model number matters for parts

Craftsman 42-inch riding mowers can share the same deck size but use different blade styles, mandrel assemblies, and electrical parts. Using the correct model number helps us match the right diagrams and part IDs.

Examples of model-matched parts for this tractor

What you are replacing	Example part on this model	What it affects
Mower blade (mulching)	Mulching blade 532134149	Cut quality and mulching performance
Mower blade (high-lift)	High-lift blade 532138971	Bagging and side discharge airflow
Ignition switch	Ignition switch 532193350	Starting and run power to circuits
PTO switch	PTO switch 582107601	Blade engagement control

Quick tip if you see a different number (like 13AN77XSA93)

Numbers such as 13AN77XSA93 are used on some other Craftsman riding mower lines and do not match this Craftsman tractor’s manual identification. For this page, the correct model identification is 917.275632 / 917275632.

Ordering the right parts

Once you confirm the model number from the ID label, you can order replacement parts from the parts list for model 917275632 on this page, or search by model number on Sears PartsDirect.

Craftsman model 917275632 was produced during the LT-series era; most tractors in this model family were built in the early-to-mid 2000s. To pinpoint the exact build year for your specific tractor, use the serial number and date code information shown in the 917275632 owner's manual.

How to find the exact year on your tractor

We use the tractor’s identification label and date code because the model number alone can span multiple production runs.

• Look for the model/serial label (commonly under the seat, on the frame near the seat pan, or under the hood area).
• Write down the serial number exactly as shown.
• Check for a date code on the label; many Craftsman-built tractors use a numeric date format.
• Compare what you find to the identification guidance in the 917275632 owner's manual.
• If the label is damaged, inspect the tractor for replaced panels (hood, fender/footrest) that may not match the original build.

Quick reference: what you can confirm from the documentation

The documentation confirms the model and many component part numbers, but the build year is determined from the serial/date code on the tractor.

Item	What it tells you	Where to look
Model number (917275632)	Identifies the tractor family/configuration	ID label; manual parts lists
Serial number	Identifies your specific unit	ID label on tractor
Date code	Determines the build date/year	ID label (format varies)

Why it matters

The exact year affects parts fitment and revisions (deck components, electrical switches, chassis pieces). For example, the manual’s mower deck list shows model-specific deck parts such as the 42-in blades and mower housing; ordering by the correct build information helps avoid mismatches like the wrong blade style or mandrel setup.

Parts that commonly vary by production run

When you confirm the year, these are the types of parts we match most carefully:

• Mower deck blades (hi-lift vs mulching)
• Mandrel and mandrel shaft components
• Electrical starting and PTO controls
• Belts and belt keepers
• Chassis and fender/footrest assemblies

If you’re replacing deck parts, match what’s installed now to the parts list; common deck items for this model include the lawn tractor 42-in deck high-lift blade 532138971 and the husqvarna lawn tractor mulching blade, 21-in 532134149. You can also search by model number on Sears PartsDirect if you’re comparing multiple diagrams or assemblies.
