Craftsman 917370920 lawn mower Parts

We do not recommend leaving gasoline in your Craftsman walk-behind mower model 917370920 for long storage; fuel can go stale, cause hard starting, and create fuel-system problems. For short gaps between mows, fresh fuel is fine, but for end-of-season storage, drain or treat the fuel.

Best practice for short-term vs. storage

• Short term (days to a couple weeks): Keep the tank sealed and use fresh gasoline.
• Long term (seasonal storage): Do not store gasoline from one season to the next; either run the tank dry or use a fuel stabilizer and follow the storage steps in the 917370920 owner's manual.
• If it already sat: Expect “stale fuel” symptoms like no-start, surging, or rough running.

What to do before storing the mower

• Let the engine cool completely before putting the mower away.
• Decide on a fuel plan: drain the tank or stabilize the fuel.
• If you drain it, run the engine until it stops to help clear fuel from the carburetor.
• Store fuel only in a clean, non-rusting gas can; replace rusty cans.
• Store the mower in a ventilated area away from ignition sources.

Quick decision table

Situation	Recommended action	Why
Mowing again soon	Use fresh fuel; keep cap tight	Prevents moisture and contamination
Storing 30+ days	Drain fuel or stabilize and run engine	Reduces stale-fuel and varnish issues
Won’t start after sitting	Replace old fuel; check air filter and spark plug	Stale fuel is a common no-start cause

Why it matters

Old gasoline is a top cause of “does not start” complaints on walk-behind mowers; it can leave deposits that restrict fuel flow and make the engine difficult to start and keep running.

For a Craftsman walk-behind mower like model 917370920, you can look up the model number by finding the model/serial label on the mower deck or handle area, then matching that number in the parts list and diagrams in the 917370920 owner's manual. Using the exact model number ensures you get the right blade, belt, and drive parts.

Where to find the model number on a walk-behind mower

Check these common label locations first (clean off grass and dirt so the tag is readable):

• On top of the mower deck near the engine
• On the rear of the deck near the bagger door or discharge area
• On the side of the deck near a rear wheel
• On the handle support brackets or handle crossbar area
• Stamped into the deck (less common) if the sticker is missing

How to use the model number once you find it

After you locate the tag, use the full model number exactly as shown (including dots or dashes if present). For this mower, the manual identifies it as 917.370920.

• Confirm the model number matches your tag
• Use the exploded-view diagrams to identify the exact part name
• Match the part name to the part number/part ID before ordering
• Keep the model number handy for future maintenance (blade, belt, wheels)

Quick example: model-specific parts you can match by diagram

These are examples of parts called out in the 917370920 diagrams and parts list:

What you are replacing	What to match in the diagram/parts list	Example part anchor
Blade	Deck/blade section	Husqvarna lawn mower 22-inch deck 3-in-1 blade 532421825
Drive belt	Drive system section	Lawn mower ground drive belt, 3/8 x 35-3/8-in 532421527
Zone control cable	Handle/control section	Lawn mower zone control cable 587326602

Why it matters

Craftsman model numbers often look similar across different 22-inch, power-propelled mowers. Using the exact model number (and the matching diagram callouts) prevents ordering a blade, belt, or cable that fits a different deck or drive setup.

On the Craftsman walk-behind mower model 917370920, the main parts include the engine controls, handle and safety controls, cutting deck components (blade and discharge parts), and the drive system (belt, wheels, axle, and gear case). For the complete illustrated list, use the 917370920 owner's manual.

Major lawn mower parts (what they do)

• Handle and controls: upper handle, lower handle, control bar, zone control cable
• Cutting system: mower blade, blade hardware, deck baffles, rear skirt
• Discharge and bagging: discharge deflector, grass bag, grass catcher frame, mulching door
• Self-propel drive (if equipped): drive control assembly, drive belt, drive pulley, gear case (transaxle), rear axle
• Wheels and height adjust: front and rear wheels, wheel adjuster hardware
• Safety and labels: decals, shields, belt retainers, fasteners

Common parts you may replace on this model

These are frequently serviced items on model 917370920:

• Lawn mower zone control cable 587326602 (engine stop and operator presence control)
• Lawn mower ground drive belt, 3/8 x 35-3/8-in 532421527 (self-propel drive)
• Husqvarna lawn mower 22-inch deck 3-in-1 blade 532421825 (cut quality and vibration)

Quick “system map” of a walk-behind mower

System	What you see	Typical related parts
Operator controls	Handle and control bar	Zone control cable, knobs, brackets
Cutting deck	Under the mower	Blade, baffle, rear skirt, fasteners
Discharge/bagging	Side/rear opening	Deflector, grass bag, mulching door
Drive system	Wheels and belt area	Drive belt, pulley, gear case, axle

Why it matters

Knowing the part groups helps you troubleshoot faster. For example, poor cutting usually points to the blade or deck baffles, while “won’t move” problems usually point to the drive belt, pulley, or gear case.

Safety notes when inspecting parts

• Disconnect the spark plug wire before working near the blade
• Stop and inspect the mower if you strike an object
• Never adjust wheel height with the engine running
• Wear gloves when handling the blade

For an elderly person, the best lawn mower is usually a self-propelled model with easy starting, simple controls, and low push effort; many people prefer battery mowers for this. If you already own a Craftsman 917370920, keeping the drive system and blade in top shape can make it much easier to handle.

What to look for (features that reduce strain)

• Self-propelled drive: reduces pushing effort on flat and sloped lawns.
• Easy start: push-button (battery) or a smooth, reliable pull start (gas).
• Lighter weight and good balance: easier turns and less fatigue.
• Easy height adjustment: never adjust wheel height with the engine running.
• Comfortable handle and controls: easy-to-squeeze zone control bar.
• Good cut quality with fewer passes: a sharp blade and proper mowing height help.

If you already have a Craftsman 917370920: make it “senior-friendly”

A well-maintained mower feels dramatically lighter to use. For this model, we focus on the items that most affect effort and control:

• Keep the blade sharp and balanced; consider replacing it with the husqvarna lawn mower 22-inch deck 3-in-1 blade 532421825 if it is bent, nicked, or worn.
• If the self-propel drive feels weak or inconsistent, inspect the belt and replace the lawn mower ground drive belt, 3/8 x 35-3/8-in 532421527 when glazed, stretched, or cracked.
• If the operator presence (zone control) feels stiff or doesn’t fully engage, check cable routing and condition; replace the lawn mower zone control cable 587326602 if it binds or has broken strands.
• Reduce pushing effort by mowing dry grass and avoiding overgrowth; the manual recommends cutting only the top one-third of the grass.

Quick comparison: battery vs gas for seniors

Feature	Battery walk-behind	Gas walk-behind (like 917370920)
Starting	Push-button	Pull start, more upkeep
Weight/handling	Often lighter	Often heavier
Maintenance	Lower	Higher (fuel, oil, tune-ups)
Runtime	Limited by battery	Refill and keep going

Why it matters

Lower push effort and simpler starting reduce fall risk and fatigue. On a self-propelled mower, a sharp blade and a healthy drive belt also mean fewer passes, less wrestling in turns, and a cleaner cut.

• Confirm the model is written exactly as 917.370920 (sometimes shown without the dot as 917370920).
• Record the serial number and any date code printed on the label.
• Compare major assemblies listed for this model (for example, zone control cable, drive belt, wheels) to ensure you are working with the correct variant.
• If the label is missing or unreadable, use the parts list diagrams in the manual to confirm the configuration.

Model confirmation using common parts for this mower

The 917.370920 manual parts list calls out several assemblies that help confirm you have the right model. Here are a few examples you can cross-check:

What you check	What it tells you	Example part for this model
Blade and deck setup	Confirms 22-inch walk-behind deck family	Husqvarna lawn mower 22-inch deck 3-in-1 blade 532421825
Drive system	Confirms self-propelled drive layout	Lawn mower ground drive belt, 3/8 x 35-3/8-in 532421527
