Craftsman 247889330 33" wide cut mower Parts

Common problems on the Craftsman 247889330 gas walk-behind mower are hard starting, rough running, poor cutting, drive or belt issues, and abnormal vibration after striking debris. We troubleshoot by checking fuel, air flow, ignition, blade condition, and the drive system settings in the 247889330 owner’s manual.

Most common symptoms and likely causes

• Won’t start or starts then dies: stale fuel, dirty carburetor, clogged air filter, fouled spark plug, choke/throttle set wrong
• Runs rough or surges: restricted fuel flow, dirty carburetor, air leak, partially clogged filter
• Poor cut quality or uneven cut: dull or bent blade, deck height set wrong, wet grass buildup under the deck
• Excessive vibration: blade damage, loose fasteners, spindle damage (often after hitting an object)
• Self-propel or drive problems: worn or loose belt, idler pulley wear, drive cable out of adjustment

Quick checks we recommend first (safe and fast)

• Set choke for a cold start, then move to fast for mowing; the manual notes best performance is at fast.
• Use fresh gasoline; drain and refill if fuel is old or smells sour.
• Inspect the blade for bends, cracks, or heavy nicks; tighten mounting hardware.
• If you strike a foreign object and vibration starts, stop the engine and inspect immediately before mowing again.
• Keep nuts and bolts tight; vibration and poor cutting often trace back to loose hardware.

Example wear parts on this model

Problem area	What you’ll notice	Example part from our list
Cutting blade	ragged cut, vibration	Blade (part number 742-04154)
Drive belt	weak or no drive, slipping	V-belt (part number 754-04139)
Idler pulley	squeal, belt won’t tension	Pulley, idler, 4.25" dia. (part number 756-04129)

Why it matters

Abnormal vibration is a warning sign. Continuing to mow can damage the spindle assembly and loosen hardware. The manual also stresses stopping the engine and waiting for the blade to fully stop before clearing clogs or removing the grass catcher.

The model number for this Craftsman walk-behind mower is 247.889330 (often written without the dot as 247889330). You can confirm it on the identification label and in the Craftsman 247889330 owner's manual, which lists the mower as “Model No. 247.889330.”

Where to find the model number on the mower

We recommend checking the mower’s model tag first, then matching it to the manual.

• Look on the rear of the deck near the discharge area
• Check around the engine mounting area on the deck
• Look near the handle mounting brackets
• Record the full model exactly as shown (including any dots)
• If a serial number is present, write it down too (helpful for parts lookups)

Model number formats you may see

Both formats refer to the same mower model.

How it may appear	What it means
247.889330	Standard Craftsman model format (with dot)
247889330	Same model number without punctuation

Why it matters

Using the exact model number ensures you get the right parts for your Craftsman 33-inch wide cut mower, especially for fit-critical items like the blade, belts, cables, and spindle assemblies. Even small model-number differences can change deck hardware and drive components.

On the Craftsman walk-behind mower model 247889330, the mower’s model and serial number are printed on the mower’s identification label on the machine (not stamped into the engine). You can also confirm the model number on the cover of the 247889330 operator's manual.

Where to look on the mower

We recommend checking these common ID-label locations first:

• Rear of the deck near the discharge chute area
• On the frame near the handle mounting points
• Near the transmission area (rear drive components)
• Under the belt cover area (if equipped)
• Any flat, protected surface on the deck where a label will not get scraped off

Mower model number vs. engine model number

It’s easy to mix these up. Here’s the difference:

What you’re identifying	Where it’s found	Why it matters
Mower model number (247889330)	On the mower’s ID label	Used to match Craftsman/MTD deck, drive, and handle parts
Engine model/type/code	On the engine (often stamped or on an engine label)	Used to match engine parts like spark plug, carburetor, air filter

Tips to read the label successfully

If the label is dirty or faded, these steps usually help:

• Brush off dry grass and debris first
• Wipe with a damp rag and mild soap (avoid harsh solvents)
• Use a flashlight at a low angle to make faint printing easier to see
• Take a close-up photo and zoom in to read small characters

Why it matters

Using the correct mower model number ensures you get the right walk-behind mower parts for the 33-inch wide cut deck, such as the blade, belts, pulleys, and cables. The engine number is helpful too, but it does not identify the mower’s chassis and drive system.
