Craftsman 917253790 tractor Parts

The Craftsman riding mower model 917253790 uses a gasoline engine, but the exact engine brand, horsepower, and model are identified on the engine label and in the specifications section of the owner's manual. Use your mower’s model and serial information to match the correct tune-up and starting parts.

How to identify the exact engine on model 917253790

Check these locations on the mower:

• Engine blower housing or valve cover label (usually lists engine model, type, and code)
• Under the hood near the engine shroud
• Frame tag for the tractor model and serial number (helps confirm the correct parts list)
• The specifications pages in the owner's manual

Why the engine ID matters

Craftsman tractors in the 917-series were built with different engine families over time. The engine model number is what determines the correct maintenance parts (spark plug, air filter, fuel filter) and some starting components.

Common starting-system parts that must match your engine and wiring

If you’re troubleshooting a no-start or click-no-crank condition, these parts are commonly involved:

• Battery and battery cables (clean and tight connections)
• Starter solenoid (switches battery power to the starter)
• Ignition switch (sends start signal and powers safety circuits)
• Safety interlock switches (seat, brake, PTO)

If your symptoms match a click but no crank, use riding lawn mower engine clicks but doesnt turn over video for a step-by-step diagnostic flow.

Quick reference: what to record before ordering parts

Tractor model number: 917253790	Tractor frame tag	Confirms correct tractor diagrams
Tractor serial number	Tractor frame tag	Confirms production variation
Engine model/type/code	Engine label	Matches tune-up and engine-specific parts

Yes, replacing the engine on your Craftsman 917253790 front-engine lawn tractor is worth it when the tractor’s deck, steering, and drive system are still solid and the total engine-swap cost stays well below the cost of replacing the whole machine. Use the maintenance and safety guidance in the owner's manual to plan the job.

Quick decision checklist

• The mower deck is not rusted through or cracked (especially around spindle/mandrel mounts).
• The tractor still drives smoothly (no slipping, grinding, or loss of power under load).
• You can get the wear parts you typically replace each season (blades, belts, pulleys).
• The engine failure is major (thrown rod, no compression) rather than a tune-up issue.
• You can do the swap yourself or have a clear labor estimate before buying an engine.

Cost rule that works

A practical rule: replace the engine when the swap totals less than about 50% of the tractor’s replacement cost and the rest of the machine is in good condition.

If your tractor is...	Engine swap usually makes sense when...	Better choice when...
Mechanically solid	Deck and drive are healthy	Deck is damaged or drive system is failing
Easy to maintain	You can still get common parts	Multiple major systems need work
Used regularly	You want to keep the same attachments/deck	You need a different size or features

What to inspect on model 917253790 before you decide

Focus on the systems that commonly determine whether the tractor is “worth it”:

• Deck and spindles/mandrels: wobble, noise, or repeated blade loosening can point to spindle/mandrel wear (see lawn tractor mandrel housing 587819701).
• Blades and cut quality: bent blades or severe vibration means you will be replacing blades and checking balance; the manual notes blades must be kept sharp and tightened to 45 to 55 ft-lbs.
• Belts and idlers: glazing, cracking, or frequent belt throw can add cost quickly (common wear item: husqvarna lawn tractor belt, 1/2 x 101-1/6-in 592855001).

Why it matters

An engine swap only pays off when it restores a reliable tractor. If the deck, blades, and drive components are already near end-of-life, you can end up chasing multiple repairs after the engine is replaced.

A Craftsman “6.75” walk-behind mower is identified by its full model number on the product label; a common example is model 917377911 (a Craftsman 21-inch 6.75-hp rotary mower). For your Craftsman 917253790 front-engine lawn tractor, the correct model number is 917253790 as shown in the owner's manual.

Where to find the model number on a Craftsman mower

Look for the model label in one of these common spots:

• On the rear of the mower deck near the discharge chute
• On the frame near the rear wheels
• Under the seat (riding mowers and lawn tractors)
• Near the engine mounting area or control panel
• On a sticker or metal tag with model and serial information

Why “6.75” is not the model number

“6.75” is a power rating used on many Craftsman walk-behind mowers, so it does not uniquely identify the machine. The model number is what we use to match the correct parts list, blades, belts, and diagrams.

Quick ID checklist (what to write down)

Before ordering parts or looking up diagrams, we recommend recording:

• Model number (example: 917377911)
• Product type (walk-behind mower vs. riding mower/tractor)
• Deck size (often 21-inch walk-behind, or 42-inch tractor deck)
• Serial number (helps confirm production run)

Walk-behind vs. lawn tractor: what changes

Item	Walk-behind mower	Front-engine lawn tractor
Typical model label location	Deck/frame	Under seat/frame
Common wear items	Blade, air filter, spark plug	Deck belt, blades, pulleys, electrical parts
Example from this page	Not applicable	Craftsman 917253790

Why it matters

Using the exact model number prevents ordering the wrong blade, belt length, or electrical part. For example, this Craftsman 917253790 tractor commonly uses 42-inch deck components such as the lawn tractor 42-in deck high-lift blade 532138971 and drive system parts like the lawn tractor ignition switch 532193350.

The Craftsman lawn tractor model 917253790 is a 2005 model year. You can also confirm the build information by checking the product identification label on the tractor and comparing it to the identification details shown in the owner's manual.

How to confirm the year on the tractor

Look for the model and serial number label (commonly under the seat or on the rear fender area). Once you find it:

• Verify the model number reads 917253790
• Record the serial number exactly as shown
• Note any date code or “MFD” (manufacture) marking if present
• Keep the label info with your maintenance records

Why we call this a 2005 model

The documentation for this Craftsman 917253790 includes a 2005 marking in the identification section, which aligns with the model’s production labeling.

Year vs. manufacture date (quick guide)

Sometimes the model year and the exact build date are not the same thing. Here is how to think about it:

What you’re checking	What it tells you	Where to find it
Model number (917253790)	Model family and configuration	ID label, owner's manual
Model year (2005)	The model’s year designation	Documentation and ID label
Serial number/date code	The specific unit’s build timing	ID label on tractor

Why the year matters for parts and repairs

Using the correct year and model helps ensure you get the right deck, blade, belt, and electrical parts for your tractor. For example, deck and blade compatibility can vary even within similar Craftsman tractor series.

If you are replacing cutting components, match your deck size and blade style to the parts list for this model; common examples on this page include the lawn tractor 42-in deck high-lift blade 532138971 and the husqvarna lawn tractor 42-in deck 3-in-1 blade 532422719.
