Craftsman 917377795 rotary lawn mower Parts

Gas walk-behind mowers like the Craftsman 917377795 are not universally “phased out”; instead, rules vary by state and city, and many restrictions focus on new equipment sales or commercial use rather than banning existing mowers. For safe operation and maintenance details, use the 917377795 owner's manual.

What’s happening (in plain terms)

Most changes are policy-driven (noise and emissions goals), so the impact depends on where you live and whether you’re a homeowner or a pro.

• Some areas restrict new sales of certain gasoline-powered outdoor equipment.
• Some areas set rules for commercial landscaping fleets.
• Many places still allow continued use of existing gas mowers.
• Battery mowers are growing fast, but gas models remain widely supported with parts and service.

How to decide what to do with your current mower

If your Craftsman 917377795 runs well, keeping it maintained is usually the most practical move.

• Keep fresh fuel and consider stabilizer for storage.
• Change engine oil on schedule (this mower ships without oil in the engine when new).
• Keep the blade sharp and replace it if bent.
• Clean grass buildup from the deck and drive wheel areas.
• Store safely: let the engine cool; avoid storing with fuel indoors near ignition sources.

Quick comparison: gas vs battery (typical homeowner use)

Feature	Gas walk-behind mower	Battery walk-behind mower
Runtime	As long as you have fuel	Limited by battery capacity
Maintenance	Fuel, oil, air filter, spark plug	Mostly blade and cleaning
Storage	Fuel handling required	Battery care and charging
Noise	Typically louder	Typically quieter

Why it matters

Local rules can affect future purchasing options and service practices, but your day-to-day reliability still comes down to maintenance. Following the manual’s safety and upkeep guidance helps your mower start easier, cut cleaner, and last longer.

For Craftsman model 917377795, use unleaded regular gasoline (87 octane). Higher octane (like 91) does not add power or protection in a mower engine; the key is using fresh fuel and the correct type listed in the 917377795 owner's manual.

What fuel to use (and what to avoid)

• Use fresh unleaded regular fuel.
• Avoid stale gas (especially fuel left from last season).
• Keep fuel clean; dirt or rust in the gas can cause running and starting problems.
• Do not store gasoline from one season to the next.
• If your gas can starts to rust, replace it to prevent contamination.

87 vs 91: what changes and what does not

Higher octane fuel mainly resists knock in high-compression engines. Most walk-behind mower engines are designed for regular fuel, so octane above 87 typically provides no benefit.

Fuel choice	Works in 917377795?	Best use case
87 octane (regular)	Yes	Everyday mowing, normal temps
91 octane (premium)	Yes, but unnecessary	Only if it is the only fresh fuel available

If your mower is hard to start after fueling

Stale fuel is a common cause of “won’t start” symptoms.

• Confirm you have fresh gas in the tank.
• Check the air filter and spark plug connection.
• Make sure the control bar is held in the start/run position.
• If the engine still will not crank or the rope is stuck, follow lawn mower pull cord stuck.

Why it matters

Using the correct fuel (unleaded regular) and keeping it fresh helps prevent carburetor varnish, fuel system contamination, and no-start issues, which reduces downtime and protects the engine.
