What are the most common issues with 917370927?
The most common problems we see on the Craftsman 917370927 walk-behind mower are drive issues (self-propel not pulling), poor cut quality, and discharge or mulching problems. These usually trace back to wear items like the drive belt, blade and adapter, or chute and control cables; use the owner's manual for model-specific adjustments and safety steps.
- Self-propelled stops working or slips: worn or stretched drive belt, worn drive wheel components, or a sticking drive control.
- Uneven cut, vibration, or poor mulching: bent or dull blade, damaged blade adapter, or debris buildup under the deck.
- Clumping or side discharge not closing: weak or broken chute door springs, damaged clipping deflector, or mulching door not sealing.
- Engine runs but blade does not spin: blade adapter damage or loose mounting hardware.
- Bail/zone control feels wrong: stretched, kinked, or misrouted zone control cable.
- Shut the mower off, disconnect the spark plug wire, and tip the mower safely (air filter and carburetor up).
- Inspect the underside for packed grass; clean the deck and check for a bent blade.
- Check drive engagement: with the drive control held, the belt should tension and the wheels should drive.
- Inspect cables for fraying and verify clamps are holding the cable housing securely.
- Confirm the discharge chute door snaps closed and springs return it fully.
| Symptom | Part to check | Example part on this model page |
|---|---|---|
| No/weak self-propel | Drive belt, pulleys, transmission | Poulan lawn mower ground drive belt, 3/8 x 35-1/2-in 580364604 |
| Vibration or poor cut | Blade, blade adapter | Husqvarna lawn mower 22-inch deck 3-in-1 blade 532421825, husqvarna lawn mower blade adapter 581851501 |
| Chute will not close | Chute springs, deflector | Husqvarna lawn mower discharge chute door spring, left 532419949, husqvarna lawn mower discharge chute door spring, right 532419948 |
A slipping drive system, damaged blade, or stuck discharge chute can reduce cut quality and increase wear on the transmission, pulleys, and deck hardware. Catching these issues early keeps the mower cutting cleanly and helps prevent bigger repairs.

What kind of gas do I put in my push lawn mower?
For the Craftsman lawn mower model 917370927, we recommend using fresh unleaded gasoline; regular 87-octane is the typical choice. If you can, choose fuel with 0% ethanol because ethanol-blended gas can absorb moisture and cause hard starting after storage. See the fuel guidance in the 917370927 owner's manual.
- Unleaded gasoline, typically 87 octane
- Fresh fuel (avoid gas that has been sitting for weeks or months)
- 0% ethanol (E0) when available; otherwise E10 is commonly used
- Use a clean, approved gas can to prevent dirt and water contamination
- Add fuel stabilizer if the mower will sit more than about 30 days
| Fuel type | What it is | Best use case | Storage risk |
|---|---|---|---|
| E0 | Unleaded with 0% ethanol | Best for seasonal equipment | Lower |
| E10 | Unleaded with up to 10% ethanol | OK for frequent mowing | Higher (absorbs moisture) |
- Buy only what you will use in 30 days.
- Keep the gas cap tight and store fuel in a cool, dry place.
- If the mower starts running rough, drain old fuel and refill with fresh gas.
- Before off-season storage, follow a winterizing routine like how to winterize a lawn mower.
Fuel quality is the most common reason a push mower becomes hard to start after sitting. Fresh unleaded gas and good storage habits help protect the carburetor, reduce varnish buildup, and keep your Craftsman 917370927 running reliably.
