Craftsman 247377050 lawn mower Parts

For the Craftsman lawn mower model 247377050, we use standard 4-cycle small-engine oil; SAE 30 is the typical choice for warm-weather mowing, and SAE 10W-30 is a better all-temperature option for many climates. For the exact oil type and fill amount, follow the 247377050 owner's manual.

Recommended oil types (what to buy)

Use 4-stroke engine oil (never 2-cycle mix) and choose viscosity based on temperature:

• SAE 30: best for consistently warm conditions
• SAE 10W-30: good for variable temperatures and easier cold starts
• Synthetic 5W-30: strong cold-weather performance and year-round protection
• Use an oil labeled for small engines or 4-cycle use

How much oil does it take?

Most walk-behind mower engines take about 15 to 20 oz of oil, but the correct fill level is always set by the dipstick or fill plug threads, not by “ounces.” Use the 247377050 owner's manual for the model-specific capacity and checking method.

What you are doing	Best practice	What to avoid
Adding oil	Add a little, recheck, repeat	Filling to a guessed amount
Checking level	Mower on level ground	Checking on a slope
Oil choice	Match viscosity to temperature	Using 2-cycle oil or mixed fuel

Quick oil-change checklist

• Run the engine 1 to 2 minutes to warm the oil (then shut off)
• Disconnect the spark plug wire before servicing
• Drain oil into an approved container
• Refill slowly and recheck the dipstick level
• Start and run briefly, then recheck for correct level and leaks

Why it matters

Correct oil viscosity helps the engine lubricate properly, reduces wear, and improves starting. Overfilling can cause smoking and fouled plugs; running low can quickly damage the engine.

The model number for this Craftsman walk-behind lawn mower is 247377050. You will typically find it on the mower’s model tag (often on the rear of the deck, near the handle mount, or on the side of the deck), and it is the number we use to match the correct parts and diagrams.

Where to find the model number on the mower

Check these common locations on Craftsman walk-behind mowers:

• Rear of the mower deck, behind the engine
• Left or right side of the deck near the wheels
• Near the handle brackets or height adjuster area
• On a sticker or metal plate labeled “Model” and sometimes “Serial”

If the tag is dirty or faded, wipe it clean and use a flashlight to read stamped characters.

Why the model number matters for parts

Using 247377050 helps us match the correct part design and fit for your exact mower, especially for items that vary by production run (wheels, cables, belts, and bagging parts).

Here are examples of parts that are model-sensitive:

• Drive system parts (belt, transmission, control cable)
• Handle hardware and brackets
• Deck components (side chute, rear skirt)
• Bagging and mulching components

Quick parts cross-check (examples)

What you are replacing	Example part for model 247377050	What it affects
Self-propel drive belt	954-04259A	Mower movement and drive engagement
Drive control cable	946-04728	Drive control response at the handle
Grass bag	964-04154	Bagging performance and fit

Helpful reference

For model tag location and identification details, use the 247377050 owner’s manual.

Why it matters

A single digit off in the model number can lead to the wrong Craftsman or MTD-style part, which can cause poor fit, unsafe operation, or repeat failures.

Craftsman model 247377050 is a model number, not a date code, so it does not directly tell the year. To find the year your mower was built, we use the engine date code or the product ID/serial tag on the mower, then confirm the format shown in the 247377050 owner's manual.

Where to find the build date on a walk-behind mower

Check these common locations (clean the area first so the stamp is readable):

• Engine shroud (top cover) near the starter housing
• Valve cover or muffler heat shield area
• Engine block stamping near the spark plug
• Mower deck tag (often near the rear discharge opening)
• Rear axle area or handle bracket tag

How to decode what you find

Different components use different formats. Here are the most common ones we see on Craftsman walk-behind mowers:

What you find	What it usually means	Example result
6-digit date code (MMDDYY)	Month, day, year	072811 = July 28, 2011
4-digit date code (MMYY)	Month and year	0711 = July 2011
Serial number with letters + numbers	Year is embedded; varies by maker	Use the manual’s ID section

Quick checks that prevent wrong-year guesses

• Do not use 247377050 as the year; it is only the mower’s model identifier.
• If you see a 6-digit number, read it as MMDDYY unless the tag states otherwise.
• If the mower has been repaired, the engine date can be newer than the mower deck.
• Match the ID tag information to the identification section in the 247377050 owner's manual.

Why it matters

Knowing the correct year helps us match the right Craftsman parts and hardware, especially for items that change by production run (drive system parts, wheels, and control cables).

On a Craftsman walk-behind mower like model 247377050, the model number is typically printed on a product ID label attached to the mower deck or rear housing area. We use that exact model number to match the correct Craftsman parts list and diagrams for your mower.

Common places to check on a Craftsman walk-behind mower

Look for a sticker or metal tag; it is usually near areas that stay relatively protected from grass and debris:

• Top of the mower deck, near the engine mounting area
• Rear of the deck, behind the engine or near the bagging opening
• Side of the deck, close to a rear wheel or height-adjuster bracket
• Rear discharge door area (lift the rear flap and look around the frame)
• Handle mounting area where the lower handle bolts to the deck

What the label looks like (and what to write down)

Most ID labels include more than one identifier. Recording all of them helps ensure an exact match.

Label item	What it’s used for	Example format
Model number	Identifies the mower platform	247377050
Serial number	Identifies your specific unit	Numbers/letters
Product number	Sometimes needed for parts lookup	Varies

Tips if the label is dirty or hard to read

• Brush off dry debris first; then wipe with a damp rag.
• Use a flashlight and take a close-up photo; zooming in often reveals faded text.
• If the sticker is scratched, look for the same info stamped on a metal tag nearby.

Why it matters

Craftsman walk-behind mowers can look similar across multiple model families, but parts like the ground drive belt, drive control cable, wheels, and deck components vary by model. Using the exact model number helps us match the correct diagrams and replacement parts the first time.

For model-specific label location details and identification info, use the 247377050 owner’s manual.
