Does it matter what gas I put in my lawn mower?
Yes. For the Craftsman lawn mower model 917376534, using the right gasoline helps it start easier, run smoother, and avoid fuel-system problems like hard starting from stale or contaminated fuel. In most cases, fresh regular unleaded gasoline (often E10) is the correct choice; avoid old fuel and keep water and dirt out of the tank.
- Use fresh, clean regular unleaded gasoline from a busy station.
- If your area sells E10 (up to 10% ethanol), it is commonly used in walk-behind mower engines.
- Avoid stale fuel (gas left sitting for weeks or carried over from last season).
- Avoid fuel that may be contaminated with water, rust, or dirt (a common cause of no-start issues).
- Do not store gasoline from one season to the next; the manual specifically warns against it.
The 917376534 manual calls out stale fuel and water in fuel as common “does not start” causes, and it also warns that rust or dirt in your gas can will create problems.
- Store gasoline in a clean, approved gas can that is not rusting.
- Keep the can tightly closed to reduce moisture absorption.
- If fuel is old, drain the tank and refill with fresh gasoline.
- Consider using fuel stabilizer for storage periods (especially off-season).
- Let the engine cool before storing the mower; do not store it indoors with gasoline in the tank.
| Symptom | Likely fuel issue | What to do |
|---|---|---|
| Won’t start after sitting | Stale fuel | Drain and refill with fresh gas |
| Starts then dies | Water/contamination | Replace fuel, check can and tank cleanliness |
| Hard starting, rough running | Old fuel or varnish | Fresh fuel; tune-up steps per manual |
Fuel quality directly affects starting and engine life. The manual notes that a clogged, dirty engine runs hotter and shortens engine life, and fuel contamination can quickly lead to repeated starting failures and poor performance.
For model-specific operating and storage guidance, follow the 917376534 owner's manual.

How to tell the year of a Craftsman lawn mower?
For a Craftsman mower, the most reliable way to tell the year is to use the model and engine identification information, then match it to the manufacturing date code. For Craftsman model 917.376534, start with the ID tag information and confirm details in the 917.376534 owner's manual.
On most Craftsman walk-behind mowers, you can identify the mower and narrow down the build year using these locations:
- Model number label on the mower deck or rear housing area
- Engine model/type/code stamped on the Briggs & Stratton engine shroud or valve cover area
- Serial number (if present) on the mower’s product label
- Date code on the engine (often the fastest way to get the year)
Because Craftsman walk-behind mower labels vary by production run, we use this practical approach:
- Confirm the mower model number (example: 917.376534).
- Use the engine code to get the build date (Briggs & Stratton engines commonly include a code that indicates the manufacturing date).
- Use the mower’s purchase timeframe as a cross-check (receipt, warranty start, or first season of use).
| What you find | What it usually tells you | Best use |
|---|---|---|
| Engine “code” number | Engine build date (often includes the year) | Most accurate for year |
| Mower serial number | Production sequence, sometimes includes date | Helpful if it includes a date format |
| Model number (917.xxxxx) | Product family identifier | Confirms correct parts/manual |
The build year affects parts compatibility and maintenance specs, especially for wear items like the blade, drive belt, and control cables. For example, using the correct 22-inch blade style helps cutting performance and protects the crankshaft.
If you are confirming the year to buy parts for Craftsman 917.376534, these are common version-sensitive items:
- Blade and blade hardware (nut/washer)
- Drive system parts (belt, pulley, transmission)
- Control cable routing and handle hardware
- Rear door, deflector, and mulch door components
If you are replacing the cutting blade on this model, match it by model number and deck size; the husqvarna lawn mower 22-inch deck 3-in-1 blade 532421825 is a common fitment item listed for this mower.

What model number is the DGS6500?
The model number DGS6500 is commonly associated with a Craftsman riding lawn tractor, not our Craftsman walk-behind mower model 917376534. For the DGS6500 tractor, the model number is typically 917.287460; for your walk-behind mower, the correct model number is 917376534 (shown in the parts list in the 917376534 owner's manual).
We recommend verifying the model number from the product ID label so you order the right parts (blade, drive belt, wheels, and control cable).
- Look for a sticker or metal tag on the frame
- For walk-behind mowers, check the rear of the deck, near the handle mounts, or by the rear discharge door
- For riding tractors, check under the seat, on the frame rail, or near the engine compartment
- Match the full model number exactly (including dots if present, such as 917.287460)
- Use the model number to match the correct engine family and parts diagrams
If you are troubleshooting or buying parts, these identifiers help you avoid mixing tractor parts with walk-behind mower parts.
| Item you have | Typical product type | Model number format | Example |
|---|---|---|---|
| DGS6500 | Riding lawn tractor | 917.xxxxxx | 917.287460 |
| 917376534 | Walk-behind mower | 9 digits (no dot) | 917376534 |
Parts are model-specific. A tractor model like DGS6500 uses different drive systems, blades, belts, and controls than a walk-behind mower like Craftsman 917376534, so confirming the model number prevents wrong-part returns and fit issues.
