Craftsman 917376790 lawn mower Parts

For a Craftsman walk-behind mower like model 917376790, it’s usually cheaper to repair routine wear items (blade, belt, cables, tune-up parts). Replacement makes more sense when the engine or self-propel drive system needs major work, or when repair cost approaches about half the price of a comparable new mower.

A practical cost rule we use

• Repair when the fix is maintenance or a single, accessible part.
• Replace when multiple major systems are failing (engine performance plus drive problems plus deck damage).
• Replace when the mower has chronic starting issues even after a tune-up.
• Repair when the mower is otherwise solid and you can restore safe, reliable operation.

Common repairs that are usually worth it

These are typical “high value” repairs because parts cost is modest and the mower often returns to normal performance:

• Replace a worn or bent blade (poor cut, vibration)
• Replace a slipping self-propel belt
• Replace a stretched/binding drive cable
• Clean under the deck and service the drive cover area
• Annual tune-up items (spark plug, air filter)

When replacement is usually the better choice

Major failures often cost more in parts and labor than the mower is worth:

• Engine internal damage (low compression, heavy smoking, knocking)
• Repeated drive failures after belt and cable replacement
• Cracked or severely rusted deck (unsafe and hard to repair)

Quick comparison table

Situation	Typical best choice	Why
Blade is dull/bent, mower vibrates	Repair	Restores cut quality and reduces wear on the crankshaft
Self-propel slips but engine runs strong	Repair	Often belt/cable related, not a full transmission issue
Engine runs poorly even after tune-up	Replace	Engine work can exceed the mower’s value
Multiple big issues at once	Replace	Costs stack quickly and reliability stays low

Parts that commonly drive repair decisions

If your mower won’t move or the drive slips, these model-matched parts are often involved:

• Belt 532157769 (self-propel drive belt kit)
• Lawn mower drive control cable 532194653 (controls engagement)
• Lawn mower transmission assembly 532415226 (major drive component)

Why it matters

A mower that cuts unevenly, vibrates, or has unreliable self-propel can become unsafe and can also accelerate wear on expensive components. Following the maintenance schedule in the manual (including annual spark plug and air filter service) helps you avoid the “replace vs. repair” decision for longer.

The most common issues we see on the Craftsman 917376790 walk-behind mower involve cutting performance (dull or loose blade and adapter), self-propel drive problems (belt, drive wheel, pawls, or transmission), and control/handling issues (cables, handle hardware, or rear door/bagger fit). Use the 917376790 owner's manual for the correct adjustments and safety steps.

Common symptoms and what usually causes them

• Poor cut quality or vibration: bent/dull blade, loose blade bolt, worn blade adapter
• Mower will not self-propel or slips: worn drive belt, worn drive pawl, damaged drive wheel, transmission wear
• Hard to pull back or wheels drag: drive components binding, wheel debris, worn dust covers
• Blade will not engage properly: blade adapter damage, blade installed incorrectly
• Controls feel loose or unresponsive: stretched/binding drive control cable, engine control cable routing issues

Quick checks we recommend first

1. Disconnect the spark plug wire before inspecting under the deck.
2. Tip the mower with the air filter and carburetor side up (common safe practice for walk-behind mowers).
3. Inspect the blade and adapter for cracks, rounding, or wobble.
4. Check the self-propel belt for glazing, fraying, or slack.
5. Verify the drive control cable moves the transmission/drive arm through its full travel.

Parts that commonly fix these problems (when worn)

Symptom	Likely wear item	Example part for this model
Vibration, uneven cut	Blade or adapter	Lawn mower blade 532406713, lawn mower blade adapter 532421176
No self-propel	Drive belt or pawls	Belt 532157769, drive pawl 532404845
Poor traction	Drive wheel	Lawn mower drive wheel 532403111
Grinding, no drive	Transmission	Lawn mower transmission assembly 532415226

Why it matters

Ignoring vibration or drive slippage can quickly damage the blade adapter, transmission pulley, and fasteners; fixing the root cause early helps protect the crankshaft area and keeps the mower safe to operate.

A “Craftsman 6.75” mower description usually refers to the engine series, not a single mower model number. For the Craftsman walk-behind mower covered by this page, the model number is 917.376790 (a 22-inch rotary mower with a Briggs & Stratton 625 Series engine). See the 917.376790 owner's manual to confirm the exact model and specifications for your unit.

Where to find the model number on your mower

We recommend matching the model number from the mower’s ID label to the manual and parts diagrams.

• Check the ID label on the mower deck (top surface near the engine) or rear deck area
• Look for a number formatted like 917.XXXXXX
• Write down the full model number and any product number information
• Use the model number (not the engine label) when ordering parts like blades, belts, and cables

“6.75” vs. mower model number: what’s the difference?

“6.75” is commonly used as an engine power/series identifier, but many different Craftsman mowers can use similar engines. The mower model number identifies the exact deck, drive system, and handle controls.

What you’re looking at	What it identifies	Example you might see
Engine label	Engine family/series	Briggs & Stratton 625 Series
Mower model label	Exact mower configuration	Craftsman 917.376790
Parts diagrams/manual	Correct replacement parts	Blade, drive belt, control cable

Why it matters

Using the correct mower model number prevents ordering the wrong blade, drive belt, or control cable. For example, this Craftsman 917.376790 uses a specific 22-inch deck setup and drive components that can differ from other “6.75” Craftsman mowers.
