How to look up Craftsman model number?
For a Craftsman riding lawn tractor like model 917273761, the model number is printed on the tractor’s identification label. On most tractors, you’ll find that label under the seat or on the frame near the rear fender area; match the full number exactly (including dots or dashes) when looking up parts or the manual.
Where to check on a riding lawn tractor
Look in these common spots first:
- Under the seat (lift the seat and check the underside area)
- On the frame rail near the rear wheels
- Near the rear fender pan or footrest area
- Under the hood near the engine compartment (less common)
- On the mower deck shell (sometimes a separate deck tag)
How to use the model number to find the right info
Once you have the full model number, use it to pull the correct diagrams, parts, and maintenance instructions.
| What you need | What to match | Example for this tractor |
|---|---|---|
| Tractor model number | Exact full model | 917273761 |
| Manual | Same model as the tractor | 917273761 owner's manual |
| Parts | Use the model to select the correct diagram section | Blades, belts, steering, wheels |
Why it matters
Craftsman tractors often share similar looks across multiple years and deck setups. Using the exact model number prevents ordering the wrong blade, belt, or steering part and helps you follow the correct safety and maintenance steps.

What year is my Craftsman mower serial number lookup?
For a Craftsman lawn tractor like model 917273761, the model number does not tell the year. The year is typically encoded in the serial number or date code on the tractor’s ID label; once you find that code, you can translate it into a build date using the format shown in the owner's manual.
Where to find the serial number/date code
On most Craftsman riding mowers and tractors, the ID label is commonly located in one of these spots:
- Under the seat pan (lift the seat and look on the frame)
- On the rear fender or fender pan near the seat
- On the frame rail near the engine compartment
- Near the transmission area on the frame
Write the serial number exactly as shown, including any letters.
How the date code is commonly formatted
Many Craftsman-built units use a 6-digit date code that reads as MMDDYY (month, day, year). Example: 072811 = July 28, 2011.
Quick decode table
| Code position | Meaning | Example (072811) |
|---|---|---|
| 1 to 2 | Month (MM) | 07 |
| 3 to 4 | Day (DD) | 28 |
| 5 to 6 | Year (YY) | 11 (2011) |
If your label uses a different pattern (letters mixed in, longer string), use the parts diagrams and identification info in the owner's manual to confirm you are reading the correct number from the correct label.
Why it matters
Knowing the build year helps us match the right parts and specs for your Craftsman 917273761, especially for wear items like blades, belts, and deck hardware.
Parts that often depend on correct identification
- Mower blades (deck type and lift style)
- Ground drive belt routing and length
- Mandrel and spindle components
- Steering and axle hardware

How to identify a lawn mower engine?
On Craftsman lawn tractor model 917273761, the most reliable way to identify the engine is to read the engine model and type numbers shown in the tractor documentation and then match them to the ID tag or stamping on the engine itself. Our owner's manual lists a Briggs & Stratton 31H777 engine with type 0297-E1 for this tractor.
Where to find the engine identification
Use these common ID locations on riding mower engines:
- Engine shroud/blower housing label (often the easiest to read)
- Valve cover area (near the cylinder head)
- Top of the engine near the cylinders (some V-twins have a stamped code)
- Engine block near the starter or muffler side
- Under the hood on a sticker near the engine compartment (sometimes)
What numbers you need (and what they mean)
For engine parts and service lookups, you typically need all of these:
| What you see on the engine | What it’s used for | Example for this tractor |
|---|---|---|
| Engine model number | Identifies the engine family | 31H777 |
| Type number | Identifies the exact build configuration | 0297-E1 |
| Code/date (if present) | Helps date the engine build | Varies |
Quick match for Craftsman 917273761
When you’re confirming you have the correct engine, match your engine tag to these manual-listed identifiers:
- Tractor model: 917273761
- Engine brand: Briggs & Stratton
- Engine model: 31H777
- Engine type: 0297-E1
Why it matters
The same tractor model can use different engine variations over time, and small differences (type number, carburetor style, ignition system) change which tune-up and fuel system parts fit. Using the engine model and type prevents ordering the wrong spark plug, air filter, or solenoid.

Is it cheaper to repair or replace a lawnmower?
For a Craftsman lawn tractor like model 917273761, repairing is usually cheaper when the fix is a normal wear item (blade, belt, solenoid) and you can do the work yourself; replacement becomes the better value when the engine or transmission needs major work or multiple big parts fail at once. See the maintenance and troubleshooting guidance in the owner's manual.
Quick rule of thumb (repair vs replace)
- Repair when the problem is isolated (one system, one or two parts).
- Repair when the tractor still cuts and drives well after basic maintenance.
- Replace when you have repeated no-start, no-drive, or poor-cut issues across seasons.
- Replace when the frame, deck housing, or drivetrain has major wear plus other problems.
- Replace when repair cost approaches the value of a comparable used tractor.
Common repairs that are typically cost-effective
These are frequent, straightforward fixes on riding mowers and tractors:
- Dull or bent blades (poor cut, vibration)
- Worn drive belt (loss of drive)
- Starter/solenoid issues (clicking, no crank)
- Deck buildup and deck leveling (poor discharge, uneven cut)
- Tire issues (low pressure causing uneven cut)
If you are replacing cutting components, the parts list for this model includes blades such as the lawn tractor 42-in deck high-lift blade 532138971 and the husqvarna lawn tractor mulching blade, 21-in 532134149.
Cost comparison table (typical)
| Scenario | What you usually replace | Typical value call |
|---|---|---|
| Poor cut or vibration | Blade(s), deck cleaning, deck leveling | Repair |
| Loss of drive | Ground drive belt, idler checks | Repair |
| Clicks but won’t crank | Battery/cables, solenoid | Repair |
| Multiple major systems failing | Engine plus transmission plus deck rebuild | Replace |
Why it matters
A well-maintained tractor can run for years, and the owner's manual maintenance schedule (lubrication, tune-up, adjustments, storage steps) helps you avoid the expensive failures that push the decision toward replacement.
