Craftsman 917377980 rotary lawn mower Parts

Gas lawn mowers are not being universally phased out, but some states and cities are restricting certain gasoline-powered outdoor equipment over time. Your Craftsman rotary lawn mower model 917377980 can still be used where allowed; local rules determine what is permitted.

Restrictions are typically aimed at reducing emissions and noise from small engines. In many areas, gas walk-behind mowers remain legal, while certain categories (often leaf blowers) may face earlier limits.

Common outcomes you may see locally:

• New sales of some gas-powered equipment may be limited by a future date
• Commercial use rules may differ from homeowner use
• Seasonal “no-use” days may be implemented in some communities
• Enforcement and timelines vary widely by location
• Battery-powered equipment incentives may be offered

Good maintenance helps reduce smoke, hard starting, and rough running, which are the issues most likely to draw complaints.

• Check engine oil level before each use
• Replace the spark plug about once per year
• Replace or service the air filter at least once each season
• Keep the underside of the mower deck clean (built-up grass makes the engine work harder)
• Use fresh fuel and consider fuel stabilizer for storage

For model-specific operating and maintenance details, use the 917377980 owner’s manual.

If your area adopts restrictions, the biggest impact is usually on new purchases or commercial operation, not immediate bans on using an existing mower. Staying on top of tune-ups also keeps performance strong and reduces visible exhaust.

Common self-propelled problems on the Craftsman 917377980 rotary lawn mower are drive not engaging, weak or slipping forward motion, and drive cutting out during use. Many issues start with control operation, then move to belt, cable/linkage, wheel traction, or transmission wear.

On model 917377980, self-propelling works when you hold the operator presence control bar down to the handle and push the drive control lever forward until it clicks, then release the lever. Confirm the steps in the 917377980 owner's manual.

• Hold the operator presence control bar firmly against the handle while you want drive
• Push the drive control lever forward until it clicks (then let go)
• To stop moving without shutting off the engine, slightly release the control bar until drive disengages
• For turns, lift the front wheels slightly while turning to help keep drive engaged

• Worn or broken drive belt (engine runs, mower will not pull)
• Stretched or misrouted drive cable/linkage (lever clicks but drive does not fully engage)
• Worn drive wheels or traction surfaces (mower slips, especially on slopes or damp grass)
• Grass buildup under the deck creating drag (drive feels weak in heavy grass)
• Transmission wear (intermittent drive, weak pull, unusual noise)

A slipping drive belt or dragging deck forces the drive system to work harder, which accelerates belt wear and can strain the transmission. Catching the cause early keeps the mower moving consistently and reduces repair cost.

For a Craftsman walk-behind mower like model 917377980, the cheapest time to buy a lawn mower is typically late summer through fall and into early winter. That is when many retailers clear out seasonal inventory, so you often see the deepest discounts on gas rotary lawn mowers.

• Late summer (August): early markdowns start as demand drops.
• Fall (September to November): the most common clearance window for walk-behind mowers.
• Early winter (December): remaining stock is often discounted further to free up floor space.
• Early spring (March to May): usually the highest prices because demand is strongest.

Even at a great price, we recommend checking these basics so you do not end up with a mower that is costly to maintain:

• Deck size and discharge style (this model is a 22-inch rear discharge mower)
• Self-propelled drive condition (if buying used)
• Engine starts easily and runs smoothly (no surging)
• Blade and deck condition (bent blade, heavy deck rust, or vibration)
• Ongoing maintenance needs (oil changes, air filter, spark plug)

Buying during clearance season can save money up front, and it also leaves room in your budget for essentials like fresh oil, a sharp blade, and tune-up items that help your mower cut cleanly and start reliably.

• For maintenance intervals and storage steps, use the 917377980 owner's manual.
• If you are evaluating blade condition on a used mower, see how to sharpen a lawn mower blade.
