Owner’s manual
What kind of oil do you use in a Craftsman lawn tractor?
For the Craftsman lawn tractor model 917252561, we use a high-quality detergent 4-cycle engine oil that meets API service classification SF or SG, then choose the SAE viscosity based on the outdoor temperature (per the oil viscosity chart in the owner's manual).
Recommended oil type and viscosity
Use detergent engine oil (API SF or SG) and match viscosity to temperature:
- 5W-30: best for cold-weather starting; check oil level more often if used above 32°F
- 10W-30: common for moderate temperatures
- Straight 30 (summer weight): commonly used in warmer weather (many tractors ship with summer weight oil)
If you mow across big temperature swings, a multi-viscosity oil (like 5W-30 or 10W-30) is convenient, but it can increase oil consumption in warm weather.
How to check and add oil correctly
We recommend this routine before every mowing session:
- Park the tractor on level ground
- Remove the oil fill cap/dipstick, wipe it clean
- Reinsert and tighten the dipstick, wait a few seconds, then remove to read
- Add oil slowly until the level reaches the "FULL" mark
- Do not overfill
Oil change intervals (what to follow)
For this Craftsman tractor, the manual schedule is:
- First oil change: after the first 2 hours of operation
- Ongoing: every 25 hours of operation
- Minimum: at least once per year
| Maintenance item | When to do it | Why it matters |
|---|---|---|
| Check oil level | Before starting; then about every 8 hours of use | Prevents low-oil engine damage |
| Change engine oil | 2 hours first change; then every 25 hours or yearly | Extends engine life |
| Choose viscosity by temperature | Before the next oil change period | Improves lubrication and starting |
Why it matters
Correct oil type and viscosity keeps the engine properly lubricated, reduces wear, and helps prevent overheating, especially when mowing in hot weather or dusty conditions.

What model number is the Craftsman 42 riding mower?
For the Craftsman front-engine lawn tractor on this page, the model number is 917252561. You can confirm it on the model plate under the seat; the owner's manual also notes this exact location and lists MODEL NUMBER 917.252561 for parts identification.
Where to find the model number on the mower
On Craftsman riding mowers like model 917252561, the model number is on the tractor’s model plate under the seat.
- Park on a flat surface and set the parking brake
- Turn the key off and remove it
- Lift the seat to access the model plate
- Write down the full model number exactly as shown
- Use that model number when looking up diagrams and ordering parts
Model number vs. deck size (why “42” can be confusing)
“42” usually refers to the mower deck cutting width (42-inch deck), not the tractor’s model number. Many different Craftsman tractors can use a 42-inch deck, so the deck size alone is not enough to identify the correct parts.
| What you’re looking at | What it tells you | Example for this tractor |
|---|---|---|
| Tractor model number | Identifies the exact tractor for parts | 917252561 |
| Deck size | Cutting width only | 42-inch mower deck |
| Engine model number | Identifies the engine for engine-specific parts | Listed separately in the manual |
Why it matters
Using the correct model number prevents ordering the wrong belt, blade, mandrel, or steering parts. For example, deck and blade-drive components can vary even among 42-inch Craftsman tractors.
Parts examples tied to this model
If you are shopping for common deck parts for model 917252561, examples on this page include the lawn tractor drive belt 532144200 and the husqvarna lawn tractor mandrel assembly 532130794.

What year is my Craftsman mower serial number lookup?
On a Craftsman riding mower like model 917252561, the model number does not contain the build year; the year is determined from the product serial number/date code on the tractor’s ID tag. Use the date-code format shown in your owner's manual to translate the serial/date code into a calendar date.
Where to find the serial number (ID tag)
We typically see the ID tag in one of these spots on front-engine lawn tractors:
- Under the seat pan or on the seat support
- On the rear fender pan near the seat
- On the frame rail (left or right side)
- Near the engine compartment or dash tower
- Near the transaxle area on the frame
How to decode the year from the serial/date code
Many Craftsman tractors use a 6-digit date code that reads as:
- MM = month
- DD = day
- YY = year
Quick examples
| Date code | Decodes to | Year |
|---|---|---|
| 072811 | July 28, 2011 | 2011 |
| 031905 | March 19, 2005 | 2005 |
| 112320 | November 23, 2020 | 2020 |
If your tag does not match the MMDDYY pattern
Some ID tags show a longer serial number plus a separate date code, or they use a different format depending on the production run. In that case, use these steps:
- Write down every character on the tag (letters and numbers)
- Look for a separate 6-digit number that resembles a date
- Check the identification section in the owner's manual
- If you’re ordering parts, match parts by model 917252561 first, then confirm fit by the part listing
Why it matters
The build year helps when you’re matching parts that changed over time (especially mower deck items like a blade, mandrel parts, and belt routing). For example, the 42-inch deck parts list for this model includes items such as the husqvarna lawn tractor mulching blade, 21-in 532134149 and the lawn tractor drive belt 532144200, and the correct selection depends on the exact deck configuration.
