What are the most common issues with 917275902?
On the Craftsman 917275902 front-engine lawn tractor, the most common problems are no-start or intermittent starting, blades not engaging, poor cutting performance, and steering or drive belt issues. These symptoms usually trace back to ignition/safety circuits, PTO controls, idler pulleys, or worn steering and axle components.
Common symptoms and what they usually point to
- Engine will not crank: ignition key, ignition harness connections, safety interlocks, or wiring damage
- Engine cranks but will not start: ignition module, fuel delivery issues, or spark problems
- Blades will not engage: PTO switch, deck belt routing/tension, or idler pulley wear
- Squealing, vibration, or uneven cut: worn idler pulleys, loose hardware, or deck drive issues
- Loose steering or wandering: steering shaft, sector gear wear, or front axle/bearing wear
Parts that commonly wear on this model
These are frequently replaced items we see tied to the symptoms above:
| Problem area | What fails most often | Example part for 917275902 |
|---|---|---|
| Blade engagement | PTO switch | Switch.pto 582107601 |
| Deck belt tension | Idler pulley | Lawn tractor blade idler pulley 532177968 |
| Starting/keys | Ignition key | Molded ignition key 532140403 |
| Steering play | Steering shaft | Lawn tractor steering shaft 532177883 |
| Front-end looseness | Axle/bearing wear | Wizard lawn tractor axle flange bearing 532009040 |
Quick checks we recommend before buying parts
- Confirm the PTO switch is fully disengaged before starting
- Inspect wiring at the dash and along the frame for rubbed-through insulation
- Check belt condition and tension; look for glazing, cracking, or slack
- Spin idler pulleys by hand (engine off); replace if rough, noisy, or wobbly
- Verify steering linkage fasteners are tight and not elongated at the holes
Why it matters
Catching a failing PTO switch, idler pulley, or worn steering component early prevents belt damage, poor cut quality, and hard-to-diagnose intermittent electrical problems.
For model-specific diagrams, adjustment points, and maintenance intervals, use the owner's manual.

What model number is the Craftsman 42 riding mower?
For the Craftsman riding mower on this page, the model number is 917.275902 (often written without the dot as 917275902). You can confirm it on the product ID label and in the 917275902 owner's manual.
How to confirm the model number on your mower
Use these quick checks to make sure you are matching the correct Craftsman tractor for parts and diagrams:
- Check the product ID label under the seat, on the frame rail, or near the engine compartment
- Match the model number format: it may appear as 917.275902 or 917275902
- Compare your mower deck size and engine details to the manual description
- Use the model number (not deck size alone) when ordering parts like belts, blades, or switches
42-inch vs 48-inch: why the deck size can be confusing
“Craftsman 42 riding mower” usually refers to the cutting deck width, not the tractor’s model number. The 917275902 manual describes a 48-inch mower deck and a 26.0 HP lawn tractor, so a 42-inch Craftsman mower is typically a different model.
| What you have | What it identifies | Example |
|---|---|---|
| Model number | Exact tractor version for parts lookup | 917275902 |
| Deck size | Cutting width only | 42-inch, 48-inch |
| Engine model | Engine-specific service parts | Kohler CV730-0043 (example) |
Why it matters for parts and repairs
Parts fit is driven by the model number, because Craftsman tractors can share similar looks but use different mower decks, steering parts, and electrical components. For example, a PTO switch or blade idler pulley can vary by model.
If you are troubleshooting a no-start or no-crank issue on this tractor, the riding lawn mower engine clicks but doesnt turn over video is a good next step.

What year did Craftsman make the 917275902?
Craftsman model 917275902 was sold in the later Craftsman 917-series era (commonly late-2000s into the 2010s); the exact year for your tractor is determined from the product identification label (model and serial/date code) on the machine and the identification guidance in the 917275902 owner's manual.
How to find the exact year on your tractor
Use the model and serial/date code from the ID label; that is what ties your unit to a specific build date.
- Park on level ground, set the parking brake, and remove the key
- Let the engine and muffler cool completely
- Lift the seat and check the frame area for the model/serial label
- Confirm the model number reads 917275902 (exact match)
- Write down the serial number and any date code shown
- Use the identification section and parts lists in the 917275902 owner's manual to interpret the information
What the model number tells you (and what it does not)
The 917-prefix identifies a Craftsman tractor platform family; it does not, by itself, guarantee a single model year.
| Item | What it tells you | Best way to use it |
|---|---|---|
| Model number 917275902 | Exact configuration family for parts lookup | Match it to diagrams and parts lists in the manual |
| Serial number/date code | The actual build timing for your unit | Use it to pinpoint the year |
| Decals and options | Helpful clues (deck size, features) | Use only as supporting info |
Why it matters
The correct year helps ensure the right fit for electrical and safety-interlock parts that can change across production runs (ignition switch, seat switch, PTO switch, wiring harness). If you are diagnosing PTO engagement while you confirm the year, the switch.pto 582107601 is one of the key components listed for this model.
