For a Craftsman walk-behind mower like model 917370442, it’s cheaper to repair when the fix is routine and the total repair cost stays under about 50% of the price of a comparable new mower. Replace when you’re facing major engine or drive-system failure, repeated breakdowns, or extensive deck damage.

Quick rule of thumb

• Repair if the mower still starts reliably and needs common wear items (blade, belt, cables, hardware).
• Replace if the repair estimate is more than half the cost of a similar new mower.
• Replace if the mower has major engine problems (low compression, heavy smoke, internal knocking).
• Replace if the self-propel/drive system needs multiple major parts at once (belt plus transmission plus wheels).
• Repair if the mower is otherwise solid and you can restore performance with a tune-up and a few parts.

What “repair” usually means on this model

These are typical, cost-effective repairs on a gas walk-behind mower:

Repair type	Common symptom	Typical value	Example part for 917370442
Blade service	Poor cut, tearing grass	High	Husqvarna lawn mower 22-inch deck 3-in-1 blade 532421825
Drive belt	Won’t move or slips	High	Lawn mower ground drive belt 532196853
Drive cable	Drive won’t engage	Medium to high	Drive cable 532447570
Discharge control	Clippings blow back	Medium	Lawn mower clipping deflector 532426129

When replacement makes more sense

Replacement is the better value when:

• The engine needs major internal work or replacement.
• The deck is rusted through, cracked, or badly bent (poor cut quality even with a new blade).
• The mower has recurring failures that keep stacking up each season.
• You need features your current mower cannot provide (different cut width, lighter weight, easier starting).

Why it matters

A mower that’s mechanically sound but needs wear parts is usually worth fixing because parts like a blade, belt, or cable restore cut quality and drive performance quickly. Once the engine or drive system becomes a repeated expense, replacement typically lowers your long-term cost per season.

For model-specific maintenance intervals and safety steps, follow the 917370442 owner’s manual.

Common problems on a Craftsman walk-behind mower like model 917370442 are usually tied to fuel quality, ignition, blade and deck wear, and self-propel drive components. Most issues show up as hard starting, rough running, poor cut quality, or the mower not pulling itself forward; the 917370442 owner's manual helps confirm the correct operating and maintenance checks.

Most common symptoms and what they usually mean

• Won’t start or starts then dies: stale gas, dirty carburetor, fouled spark plug, or a safety control issue
• Runs rough or surges: partially clogged carburetor, restricted fuel flow, or dirty air filter
• Cuts unevenly or leaves strips: dull/bent blade, blade installed upside down, or deck packed with wet grass
• Excessive vibration: bent blade, loose blade hardware, or debris wrapped around the blade adapter area
• Self-propel won’t move or slips: worn/stretching drive belt, cable out of adjustment, or transmission wear
• Grass clumps or poor bagging: wet grass, clogged deck, damaged deflector or mulching door

Quick checks we recommend first (fast, no special tools)

1. Use fresh fuel (especially after storage) and confirm the fuel cap vent is open.
2. Inspect the blade and underside of the deck; clean packed grass after the engine cools.
3. Check blade condition; replace a bent or badly worn blade with the correct 22-inch blade such as the husqvarna lawn mower 22-inch deck 3-in-1 blade 532421825.
4. If self-propel is weak, inspect the lawn mower ground drive belt 532196853 for glazing, cracking, or slack.
5. Confirm control cables move freely; a stretched or binding cable can prevent full engagement.

Troubleshooting guide by symptom

Symptom	Most likely cause	Best first action
Won’t start	Fuel/ignition	Drain old gas, check spark plug, verify controls
Poor cut	Blade/deck	Sharpen or replace blade; clean deck
Won’t self-propel	Belt/cable/transmission	Inspect belt and cable adjustment
Vibrates	Blade/hardware	Stop use; inspect blade and mounting

Why it matters

Catching blade, belt, and deck issues early protects the crankshaft, improves cut quality, and reduces strain on the drive system. Routine maintenance also prevents the most common “won’t start” problems after storage.

The Craftsman lawn mower model 917370442 is commonly equipped with a 150cc Briggs and Stratton gas engine. For the exact engine family and spec numbers used on your mower, match the engine ID tag to the listings in the 917370442 owner's manual.

How to confirm the exact engine on your mower

Engine model and spec can vary within the same mower model, so we recommend verifying what is physically on your machine.

• Look for the engine ID label on the blower housing, valve cover, or near the muffler
• Record the engine model, type, and code/spec numbers
• Compare those numbers to the engine identification section in the manual
• If your mower has electric start, also note the battery and harness routing
• Use the engine numbers when ordering tune-up parts (spark plug, air filter, carburetor parts)

What “150cc Briggs and Stratton” means in practical terms

This describes the engine size (displacement) and manufacturer; it helps you choose the right maintenance parts and fuel practices.

Item	What to look for	Why it matters
Displacement	150cc (typical for this model)	Power and general engine class
Brand	Briggs and Stratton	Parts compatibility
Engine ID	Model/type/code	Exact replacement parts

Why it matters

Using the correct engine model and spec prevents wrong-part orders and helps troubleshooting (no-start, surging, stalling). It also ensures you use the right blade and deck setup for safe cutting performance.

If you are servicing the cutting system at the same time, use the correct blade for this mower, such as the 22-inch deck 3-in-1 blade 532421825, and torque the fasteners per the manual.

Craftsman model 917370442 is identified by its model number, not a built-in “year” field. The most reliable way to determine the manufacturing date is to match the mower’s product date code (from the ID label) to the date-code format shown in the 917370442 owner's manual.

How to find the date code on your mower

On most Craftsman walk-behind mowers, the date information is on the model and serial label (often on the rear of the deck, near the handle brackets, or on the engine shroud).

• Look for a sticker or metal tag with MODEL and SERIAL information
• Write down the full serial/date string exactly as shown
• Clean the label gently if it is dirty (avoid solvents that can erase printing)
• Compare the code format to the date-code guidance in the manual
• If the label is missing, use the engine model/type code as a secondary clue

Common Craftsman date-code formats (what the numbers usually mean)

Different production runs used different formats. These are the most common patterns we see on Craftsman outdoor power equipment labels.

Format example	What it typically represents	Example result
MMDDYY	Month, day, year	072811 = July 28, 2011
YYWW	Year, production week	1128 = week 28 of 2011
YYMMDD	Year, month, day	110728 = July 28, 2011

Why it matters

Knowing the build date helps you choose the correct replacement parts and maintenance items for your Craftsman mower, especially when there are mid-year changes to the deck, drive system, or controls.

Parts that often vary by production run

• Blade and blade hardware (for example, husqvarna lawn mower 22-inch deck 3-in-1 blade 532421825)
• Drive components such as the ground drive belt
• Control cables and handle hardware
• Discharge/mulch components (deflector, mulching door)
