How to find Craftsman model number?
On a Craftsman walk-behind mower like model 917374941, the model number is printed on the mower’s ID label (often on the rear of the deck, near the height adjusters, or around the engine mounting area). Once you have it, match parts by model to ensure the blade, drive belt, and controls fit correctly; see the owner's manual for label locations and diagrams.
Where to look on a walk-behind Craftsman mower
Check these common spots on the mower itself:
- Rear of the cutting deck (behind the engine)
- Top of the deck near the engine mounting bolts
- Side of the deck near a rear wheel height adjuster
- Near the discharge opening or mulch door area
- On the handle bracket area (less common)
What the model number looks like
For this mower, the model number format is 917.374941 (you may also see it without the dot as 917374941). Record both the model number and any serial number shown.
| What you see on the label | What it means | How we use it |
|---|---|---|
| 917.374941 | Model number | Selects the correct parts diagrams and part list |
| Serial number | Production identifier | Helps confirm exact build variations |
Why it matters when ordering parts
Using the correct model number prevents mismatches in high-fit parts such as:
- Blade and blade hardware (for example, husqvarna lawn mower 22-inch deck 3-in-1 blade 532421825)
- Self-propel drive components (for example, lawn mower ground drive belt, 3/8 x 35-3/8-in 532421527)
- Drive controls and levers (for example, lawn mower drive control assembly 598688301)
Quick tips before you write it down
- Wipe the deck clean; grass buildup often hides the label.
- Copy the number exactly; one digit off can pull the wrong diagram.
- If the label is missing, use the parts diagrams in the owner's manual to visually match assemblies.

How much does it cost to repair a hydrostatic transmission on a lawn mower?
Hydrostatic transmission repairs are typically a high-cost job because the transmission is usually replaced as an assembly. For most lawn mowers, total repair cost commonly lands in the $600 to $2,500 range depending on the mower type, parts needed, and labor rates; confirm your Craftsman 917374941 service details in the owner's manual.
Typical cost ranges (what you can expect)
Hydrostatic transmission cost varies most by whether the mower is a walk-behind or a riding mower, and whether the fix is a linkage/belt issue versus a full transmission replacement.
- Diagnostic fee: often $75 to $150 (sometimes applied to the repair)
- Minor drive issue (belt, cable, adjustments): often $100 to $400
- Hydrostatic transmission replacement (riding mowers): often $800 to $2,500 installed
- High-end transmission parts alone: can approach $1,300 on some models
| Repair scenario | What is replaced | Typical total cost |
|---|---|---|
| Drive won’t move but engine runs | Belt, cable, drive control parts | $100 to $400 |
| Slips, surges, or loses drive under load | Transmission or drive assembly | $800 to $2,500 |
| Internal hydro failure on premium rider | Transmission assembly | Up to about $2,500 |
What matters most for Craftsman 917374941
Your Craftsman 917374941 is a gas walk-behind mower, and many “won’t move” complaints on walk-behind units are caused by the ground drive system (belt, control lever, cable, or drive control assembly) rather than a hydrostatic transmission.
Start with these common, lower-cost checks:
- Inspect the ground drive belt for glazing, cracking, or stretching
- Verify the drive control engages fully and returns smoothly
- Check for debris buildup around the belt path and pulleys
- Confirm the wheels and drive pawls are not worn or binding
If you’re replacing common drive parts for this model, these page-listed parts are often involved:
- Lawn mower ground drive belt, 3/8 x 35-3/8-in 532421527
- Lawn mower drive control assembly 598688301
- Lawn mower drive control lever 532425662
Why it matters
A full transmission replacement can exceed the value of some mowers, while a belt or control repair restores drive for a fraction of the cost. Checking the drive belt and controls first helps avoid unnecessary major repairs.

Should I use 87 or 89 gas for lawn mower?
For the Craftsman lawn mower model 917374941, use regular unleaded 87-octane gasoline for normal operation; higher octane (89) does not improve power or reliability in typical walk-behind mower engines. For fuel handling, safety, and maintenance details, follow the owner's manual.
What to use (and what to avoid)
- Use: fresh, clean unleaded 87 octane
- Avoid: old gas (stale fuel is a top cause of hard starting)
- Avoid: mixing fuels or using “race”/high-octane fuel as a fix for running issues
- Use the right oil and fill levels: this mower ships without oil or gasoline in the engine, so correct setup matters before first start
When 89 octane makes sense
89 octane is only useful if your engine specifically calls for it (for example, some high-compression engines). For most Craftsman walk-behind mower engines like the 917374941, 87 octane is the correct choice.
| Fuel choice | What you get | Best for |
|---|---|---|
| 87 octane (regular) | Correct combustion for most small engines | Everyday mowing |
| 89 octane (mid-grade) | No practical benefit in most mowers | Only if manual specifies |
Why it matters
Using the correct fuel helps prevent hard starting, rough running, and carburetor varnish. Just as important, safe service habits (like disconnecting the spark plug wire before cleaning or maintenance) reduce the chance of accidental blade movement.

Are zero turn baggers worth it?
Zero-turn baggers are worth it when you want the cleanest finish and the least raking; they collect clippings and leaves efficiently, especially in fall or on properties with lots of trees. For your Craftsman 917374941 walk-behind mower, bagging is also a practical upgrade because it was designed to convert from mulching to bagging using the steps in the 917374941 owner's manual.
When a bagger is worth the money
A bagger pays off most when you care about appearance, allergies, or cleanup time.
- You want a cleaner lawn with fewer clumps and less thatch buildup
- You mow around patios, pools, or sidewalks and want less blowout
- You pick up leaves regularly in fall
- You have allergy concerns and want fewer clippings left behind
- You plan to compost clippings and leaves
When it is not worth it
Baggers add cost and maintenance; mulching or side discharge can be the better choice.
- You mow large areas and do not want to stop to empty bags
- Your grass is often wet or overgrown (bags fill fast and can clog)
- You prefer returning nutrients to the lawn through mulching
- Storage space is limited
Walk-behind bagging vs zero-turn bagging (quick comparison)
| Feature | Walk-behind bagging (Craftsman 917374941) | Zero-turn bagging |
|---|---|---|
| Best for | Small to medium lawns, tighter spaces | Larger lawns, faster mowing |
| Cleanup quality | Very good when the bag is emptied before overfilling | Excellent, especially with high lift airflow |
| Downtime | More frequent emptying | Larger capacity, fewer stops |
| Cost | Lower (bag and frame) | Higher (bagger system and accessories) |
What matters most on your Craftsman 917374941
Your mower ships ready to mulch, and you convert it to bagging by installing the grass catcher and keeping the mulcher door closed and locked. For side discharge, the rear door must be closed and the discharge deflector installed. Those conversion steps help prevent blowout and keep the deck airflow working correctly. See the 917374941 owner's manual for the exact conversion procedure and safety notes.
If you need replacement bagging components, common items include the lawn mower grass bag 580943401 and the lawn mower grass bag frame 585054702. You can order model-matched parts from the parts list for this mower, or search by model number on Sears PartsDirect.
Why it matters
Choosing bagging vs mulching changes deck airflow, cut quality, and cleanup time. Using the correct configuration (rear door, mulcher door, and catcher/deflector) also helps prevent damage and improves performance.

What are the common problems with Craftsman lawn mowers?
Common problems on the Craftsman 917374941 gas walk-behind mower are no-start conditions (stale fuel, dirty air filter, bad spark plug, water in fuel), loss of power from airflow or deck buildup, poor cut from a worn or loose blade, and self-propelled drive issues from belt or control problems. See the owner's manual for the model’s troubleshooting chart and maintenance schedule.
Most common symptoms and what usually causes them
- Won’t start: dirty air filter, out of fuel, stale fuel, water in fuel, spark plug wire off, bad spark plug, control bar not held to the handle
- Loss of power: dirty air filter, grass and debris buildup under the deck, cutting too much grass at once
- Poor cut or uneven cut: worn or bent blade, uneven wheel height settings, deck packed with clippings
- Excessive vibration: loose or damaged blade, blade adapter issues, bent crankshaft (stop using the mower until inspected)
- Hard to push or loss of drive (self-propelled): worn/slipping drive belt, drive control/cable out of adjustment, transmission pulley or drive components worn
Quick checks we recommend before replacing parts
- Use fresh gasoline and drain/replace old fuel if it has been sitting.
- Inspect and clean under the deck (built-up grass can cause power loss and poor cutting).
- Check the blade for damage and tightness; replace a worn blade.
- Verify the control bar is held to the handle during starting and operation.
- Look over the drive system for obvious belt wear or a loose control cable.
Parts that commonly fix cutting and drive complaints
| Symptom | Part to inspect first | Example part for this model |
|---|---|---|
| Poor cut, ragged grass tips | Blade condition (nicks, rounding, bends) | Husqvarna lawn mower 22-inch deck 3-in-1 blade 532421825 |
| Loss of drive or slowing drive speed | Drive belt wear or glazing | Lawn mower ground drive belt, 3/8 x 35-3/8-in 532421527 |
| Drive won’t engage smoothly | Drive control linkage/cable/lever | Lawn mower drive control assembly 598688301 |
Why it matters
These issues usually trace back to basic maintenance items (fuel quality, airflow, blade condition, deck cleanliness) that directly affect starting, engine load, and cut quality. Fixing the root cause prevents repeat failures and reduces wear on the drive system.
