Craftsman 917370446 lawn mower Parts

For a Craftsman walk-behind mower like model 917370446, we use fresh, clean unleaded gasoline with no more than 10% ethanol (often labeled E10). Avoid E15 and E85 fuels because higher ethanol blends can cause hard starting, rough running, and fuel-system damage in small engines.

• Use fresh unleaded gasoline (regular grade is fine)
• Choose fuel labeled E10 or lower (0% to 10% ethanol)
• Avoid E15 and E85
• Buy only what you will use in about 30 days
• Store fuel in an approved gas can with a tight cap

1. Move the mower outdoors and let the engine cool completely.
2. Drain the tank into an approved container.
3. Refill with fresh E0 or E10 fuel.
4. If it still runs poorly, the carburetor may need cleaning.

For fuel and storage notes specific to your mower, follow the recommendations in the 917370446 owner's manual.

Higher-ethanol fuel attracts moisture and can separate during storage; that leads to corrosion, clogged carburetor passages, and degraded fuel lines. Using fresh E0 or E10 helps the engine start easier and run more consistently.

If fuel problems lead to repeated stalling or poor cutting performance, we often see customers also inspect maintenance and wear items such as:

• Blade condition (dull blades overload the engine)
• Drive system operation (belt and transmission engagement)
• Wheel traction and rolling resistance

The Craftsman 917370446 is a gas walk-behind mower; it’s the right fit for most small to medium residential lawns. In real-world use, we typically see this style of 22-inch-class mower perform best on lots up to about 1/2 acre, depending on terrain, obstacles, and grass thickness. See the 917370446 owner's manual for the recommended operating conditions.

A walk-behind mower like the Craftsman 917370446 is usually a good choice when you want maneuverability around trees, beds, and tight gates.

• Up to 1/4 acre: Fast, efficient mowing for most homeowners
• 1/4 to 1/2 acre: Still practical; plan for longer mow times
• Over 1/2 acre: You can mow it, but it becomes time-consuming; traction and fatigue matter more
• Hilly yards: Self-propel drive condition matters more than deck size
• Thick or wet grass: Expect slower ground speed and more frequent bagging or mulching checks

These factors usually matter more than the model number alone:

• Terrain: slopes, bumps, and soft ground reduce effective speed
• Obstacles: fences, landscaping, and playsets increase trimming passes
• Cutting height: higher cuts in thick grass can require a second pass
• Bagging vs. mulching: bagging can add stops and reduce pace
• Drive system condition: worn belts, wheels, or transmission reduce self-propel performance

Sizing the mower to the yard keeps mowing time reasonable and helps the mower last longer. Overworking a walk-behind mower on oversized or steep lawns increases wear on the drive system and cutting components.

If mowing time is creeping up because the mower is not pulling well or the cut quality is dropping, these model-compatible parts are common fixes:

• Replace a worn self-propel belt: lawn mower ground drive belt 532196853
• Improve cut quality with a sharp, correct blade: husqvarna lawn mower 22-inch deck 3-in-1 blade 532421825
• Restore traction with a worn drive wheel: lawn mower wheel and tire, 8 x 1.75-in 583719501

Repairing a Craftsman walk-behind mower like model 917370446 is cheaper when the problem is a normal wear item (blade, wheel, cable, belt) and the total repair cost stays under about half the price of a comparable new mower. Replacement makes more sense when the engine or drive system needs major work.

• Repair when the fix is straightforward and parts are readily available (blade, belt, wheel, cable).
• Replace when the repair involves major assemblies (engine-related issues, repeated drive failures) or multiple big-ticket parts at once.
• Repair when the mower is otherwise solid: deck is not rusted through, height adjusters are intact, and it starts reliably.

These are typical, high-value fixes on a self-propelled walk-behind mower:

• Replace a worn or bent blade (poor cut, vibration)
• Replace a slipping self-propel belt (mower will not pull well)
• Replace a damaged wheel or tire (uneven tracking, poor traction)
• Replace control cables (drive or zone control not engaging)

If you are pricing out a blade replacement for this model, start with the husqvarna lawn mower 22-inch deck 3-in-1 blade 532421825.

A mower that is repaired at the right time cuts cleaner, runs with less vibration, and avoids secondary damage (for example, a bad blade can stress the crankshaft and deck). For model-specific maintenance intervals and safety steps, follow the 917370446 owner's manual.

Common problems on a Craftsman walk-behind mower like model 917370446 are no-start or starts-then-stalls issues (fuel, spark, air), poor cutting (dull or bent blade, deck buildup), and self-propelled drive problems (worn belt, stretched cable, wheel drive wear). Use the 917370446 owner's manual for model-specific checks and adjustments.

• Use fresh gasoline; drain old fuel if it smells sour or looks dark.
• Confirm the spark plug wire is firmly seated.
• Check the air filter; replace it if it is dirty or oil-soaked.
• Inspect the blade for damage and tightness; a bent blade causes vibration and poor cut.
• Look under the deck for packed grass that blocks airflow and discharge.
• For self-propelled issues, check for a loose or worn drive belt and cable slack.

If you are seeing poor cut quality or heavy vibration, the blade is a frequent fix; for drive issues, the belt is a frequent fix.

• Cutting performance: husqvarna lawn mower 22-inch deck 3-in-1 blade 532421825
• Self-propelled drive: lawn mower ground drive belt 532196853
• Traction and rolling: lawn mower wheel and tire, 8 x 1.75-in 583719501

These problems usually get worse quickly: old fuel and restricted airflow can make starting unreliable, and a damaged blade or packed deck can strain the engine, reduce bagging/mulching performance, and leave an uneven cut.

There is no single “Craftsman 6.75” model number; 6.75 is an engine power label used on many different Craftsman walk-behind mowers. The correct model number is the 917.xxxxxx number printed on your mower’s ID tag; for this parts page, the model is Craftsman 917370446 (see the 917370446 owner's manual).

On most Craftsman walk-behind mowers, the ID tag is on the rear of the deck, near the rear discharge opening, or near the handle mounting area.

Check these common spots:

• Rear of the cutting deck (back edge)
• Left or right side of the deck, above the wheel
• Under the rear flap or near the bagger opening
• Handle bracket area (near where the handle bolts to the deck)

Craftsman walk-behind mower model numbers are typically 9 digits and often start with 917.

Parts fit is tied to the mower model number, not the engine power label. For example, the correct blade, drive belt, and wheel parts depend on the exact deck and drive system used on that model.

If you are ordering common wear items for model 917370446, examples include:

• Husqvarna lawn mower 22-inch deck 3-in-1 blade 532421825 (blade fit and lift profile)
• Lawn mower ground drive belt 532196853 (self-propel drive performance)
• Lawn mower wheel and tire, 8 x 1.75-in 583719501 (traction and drive engagement)

Once you confirm the ID tag reads 917370446 (or your specific 917 number), you can order parts from the list for that model, or search by model number on Sears PartsDirect to find the exact match.
