Where to find model number on riding mower?
On a Craftsman riding mower like model 917253891, the model number is printed on a sticker or metal tag mounted to the mower’s frame or deck area. The most common spots are under the seat, on the frame rails, or on the cutting deck near the discharge chute.
Most common places to check
Look for a label that lists MODEL, PRODUCT, or MODEL NO. (often near a barcode). Check these areas first:
- Underside of the seat or on the seat pan
- Rear frame area between the back wheels
- Left or right frame rail near the footrest
- On the cutting deck (often on the left side or near the deck’s rear edge)
- Near the engine area on the frame (not on the plastic hood)
Quick tips to find it faster
- Wipe dirt and grass off the frame and deck; labels are easy to miss when coated.
- Use a flashlight and look for a rectangular sticker with a barcode.
- If the label is scratched, take a photo and zoom in to read faint characters.
What the model number helps us match
Using the exact model number ensures we match the correct deck and hardware for your mower, including items like the blade drive belt, deck blade, and gauge wheel.
| What you’re replacing | Why the model number matters |
|---|---|
| Deck belt | Belt length and width vary by deck design |
| Blades | Blade length and center hole pattern must match |
| Gauge wheels | Mounting style and wheel size vary |
Why it matters
Craftsman riding mowers often share similar looks across years, but parts can differ by deck size, frame revision, and engine configuration. The model number is the fastest way to avoid ordering the wrong belt, blade, or fastener.

What years did they make the Craftsman 917253891?
Craftsman model 917253891 is a specific riding mower and tractor configuration; Craftsman did not publish a simple “model-year range” for every 917.x model in a way that reliably maps to a single set of calendar years. The most accurate way to identify the build timeframe is to use the tractor’s product identification label (model and serial) and then match parts by model.
How to identify the year on the tractor
On most Craftsman riding mowers, the ID label is typically under the seat, on the frame rail, or near the rear fender pan. Once you have the serial information, you can narrow the manufacturing timeframe and ensure you are ordering the correct 50-inch deck parts.
Use this checklist:
- Confirm the model number reads 917253891 exactly.
- Record the full serial number from the ID label.
- Note the engine brand and model (Briggs & Stratton, Kohler, etc.).
- Compare your deck setup (50-inch replacement deck) to the parts diagram.
- Match wear items by part ID, not by “looks similar.”
Parts clues that help confirm you have the right configuration
Even when two tractors look alike, deck and belt routing differences can change which parts fit. For model 917253891, common deck-related parts you may see in the parts list include:
- Lawn tractor blade drive belt 532110884
- Lawn tractor 50-in deck blade 532121798
- Tower lawn tractor gauge wheel 532133957
Quick fit-check table (what to compare)
| What you’re checking | What to look for | Why it helps |
|---|---|---|
| Deck size | 50-inch deck | Confirms the deck family |
| Belt path | Idler and pulley layout | Prevents ordering the wrong belt |
| Blade mounting | Center hole and star pattern (if used) | Ensures blade compatibility |
| Gauge wheels | Wheel style and mounting hardware | Confirms deck hardware set |
Why it matters
Knowing the exact year is less important than matching the exact model and serial because Craftsman made running changes within the same general era. Using the correct model-based parts list prevents belt misrouting, poor cut quality, and premature spindle or idler wear.
Ordering the right parts
We recommend ordering replacement parts directly from the parts list for Craftsman 917253891; you can also search by model number on Sears PartsDirect if you are cross-checking another Craftsman tractor.

What brand engine does Craftsman use?
Craftsman riding mowers like model 917253891 can come with engines from several manufacturers; the most common are Briggs & Stratton, Kohler, and Kawasaki. The exact engine brand depends on the specific mower configuration and the engine model installed on your tractor.
How to identify the engine brand on your mower
Look for the engine identification label on the engine itself (not the deck). On most riding mowers, you will find it:
- On top of the blower housing (near the pull-start area on some engines)
- On the valve cover or near the spark plug
- On the side of the engine shroud
- Stamped into a metal tag or printed on a sticker
- Near the muffler heat shield area
What to write down (so you get the right parts)
When you find the label, record these items exactly as shown:
- Engine brand (Briggs & Stratton, Kohler, Kawasaki)
- Engine model
- Type/spec (or spec number)
- Code/date (common on Briggs & Stratton)
- Any serial number
Why it matters
The mower model number 917253891 helps match deck and chassis parts, but engine parts are matched to the engine model and spec. That is the difference between ordering the correct air filter, spark plug, carburetor parts, or starter components the first time.

What are common problems with Craftsman riding mowers?
Common problems on a Craftsman riding mower like model 917253891 usually fall into three buckets: no-start or hard-start (battery, safety switches, fuel), poor engine performance (fuel delivery, ignition), and cutting or drive issues (belts, blades, idlers, deck hardware). Most fixes start with basic checks and a quick inspection of wear parts.
Most common symptoms and what they usually mean
- Engine won’t crank: weak battery, loose/corroded cables, bad solenoid, blown fuse, or an open safety switch (seat, brake, PTO).
- Cranks but won’t start: stale fuel, clogged fuel filter, dirty carburetor, fouled spark plug.
- Runs rough or surges: partially clogged carburetor, air restriction, water in fuel.
- Blades won’t engage or cut is uneven: worn deck belt, worn idler, bent/dull blade, deck not level.
- Poor ground drive or slipping: worn drive belt or linkage adjustment (varies by transmission style).
Quick checks we recommend first (10 minutes)
- Verify the PTO is off, brake is fully set, and you are seated (safety interlocks).
- Check fuel: fresh gasoline, tank vent open, no debris in tank.
- Inspect wiring for loose connectors and damaged insulation.
- Look under the deck for packed grass and belt damage.
- Spin the blades by hand with the engine off (they should turn smoothly without grinding).
Deck and belt problems (very common on 50-inch decks)
If the mower starts and drives but the deck performance is poor, focus on the belt path and rotating parts.
| Symptom | Most likely cause | What to inspect/replace |
|---|---|---|
| Blades slow down in thick grass | Belt slipping | Lawn tractor blade drive belt 532110884 tension, glazing, cracking |
| Belt jumps or squeals | Idler not holding tension | Idler 532102403 bearing noise, wobble |
| Ragged cut | Blade worn/bent | Lawn tractor 50-in deck blade 532121798 edge condition, balance |
Why it matters
Catching belt, blade, and idler wear early prevents repeated belt failures, reduces vibration, and helps protect spindle bearings and deck hardware (nuts, washers, and brackets) from loosening.
