What kind of oil do you use in a Craftsman lawn tractor?
For the Craftsman lawn tractor model 917287053, we use 4-cycle engine oil; choose the viscosity by temperature (the tractor is shipped from the factory filled with summer-weight oil, and you switch to a cold-weather viscosity for easier starting). For the exact viscosity chart and service interval, use the 917287053 owner's manual.
Recommended oil type and viscosity
Use 4-cycle (4-stroke) engine oil that meets current small-engine performance standards. Then match viscosity to your typical mowing temperatures.
- Warm weather mowing: summer-weight oil (as shipped from the factory)
- Cold weather starting: change to a lighter viscosity per the manual’s viscosity chart
- Never mix oil with gasoline (this is a 4-cycle engine)
- Check oil on level ground before each use
- Fill only to the FULL mark on the dipstick; do not overfill
Quick viscosity guide (typical)
These are common small-engine choices; always follow the manual’s chart when temperatures are borderline.
| Typical outdoor temperature | Common choice | Why it helps |
|---|---|---|
| Below about 40°F | 5W-30 | Easier cranking and faster lubrication at startup |
| About 40°F and above | SAE 30 (summer-weight) | Good film strength in warmer mowing conditions |
How to check and top off oil (model 917287053)
We follow the same basic steps outlined in the manual:
- Park on a level surface and let the engine cool briefly
- Remove the oil fill cap/dipstick, wipe clean, reinstall and tighten
- Remove again and read the level
- Add oil slowly until it reaches the FULL mark
- Reinstall the cap/dipstick securely
Why it matters
Correct oil viscosity protects the engine from wear, reduces hard starting in cold weather, and helps the engine run cooler under load. Overfilling can cause smoking and performance problems, so the dipstick level is the final word.

What model number is the Craftsman 42 riding mower?
For the Craftsman front-engine lawn tractor on this page, the model number is 917287053. In the 917287053 owner's manual, this tractor is also shown as model 917.28705 (a shortened, formatted version of the same model family used in the manual header).
Where to find the model number on the tractor
We recommend confirming the exact model from the tractor’s ID label so you match the correct parts list (blades, belts, electrical parts) the first time.
- Check the model/serial label under the seat or on the rear fender area
- Look on the frame near the engine compartment
- Write down both the model and serial number
- Match the model number exactly when ordering parts
- Use the manual’s model reference if the label is worn or missing
Model number formats you may see (and what they mean)
Craftsman tractors often show the model in more than one format.
| Where you see it | Example | What it means |
|---|---|---|
| Sears PartsDirect model page | 917287053 | Full model number used for parts lookup |
| Owner’s manual cover/header | 917.28705 | Manual’s formatted/shortened model reference |
Why it matters
Using the correct model number ensures you get parts that fit your 42-inch deck setup and drive system. For example, the correct model helps you choose the right deck blade style (mulching vs. high-lift) and the correct ground drive belt routing.
If you are shopping for blades for this tractor, common options include the husqvarna lawn tractor mulching blade, 21-in 532134149 and the lawn tractor 42-in deck high-lift blade 532138971 (choose based on the cut and bagging/mulching setup you run).

What year did Craftsman make the 917287053?
Craftsman model 917287053 does not have a single “model year” printed in the model number; the build date is tied to the serial number/date code on your tractor’s ID label. Use the ID label information and the 917287053 owner's manual to locate the label and confirm the correct identification details.
How to find the build date information
On Craftsman riding mowers and tractors, we use the product ID label to determine the manufacturing timeframe.
- Park on a flat surface, set the parking brake, remove the key, and let the engine cool.
- Look for the product identification label under the seat, on the seat pan, or on the frame near the rear fender.
- Write down the model number (917287053) and the serial number exactly as shown.
- Check the label for a date code or manufacture date line (format varies by production run).
- Keep that information with your records; it also helps match the correct parts diagrams.
Important clarification about model numbers
The operator’s manual text commonly shows a formatted model like 917.28705 (with a decimal) on the cover. That formatted number is a different model identifier than 917287053.
| What you see | What it means | What to do |
|---|---|---|
| 917287053 | Your Sears model number used for parts lookup | Use this for ordering parts and diagrams |
| 917.28705 | A different formatted model shown on some manuals | Do not assume specs or year match your tractor |
Why it matters
The exact build timeframe affects parts fitment on items that change during production runs, such as the mower deck drive system and hardware. For example, blade and belt selections can vary; matching by model and serial helps avoid returns.
