Craftsman 247204120 zero-turn riding lawn mower Parts

A rear-engine riding mower like the Craftsman 247204120 puts the engine behind you, which improves forward visibility and keeps the front end compact for trimming around landscaping. It is also typically simpler to maintain than many larger tractors, while still giving you seated comfort for medium-size lawns.

Key benefits you will notice

• Better sightline to the cutting path and obstacles (trees, beds, edging)
• Tighter turning and easier maneuvering in smaller yards
• More stable feel on flat ground because weight is carried over the drive wheels
• Easier deck access for basic cleaning and blade checks on many rear-engine designs
• Generally lower overall size for storage in a standard shed or garage

How rear-engine compares to other mower types

Mower type	Best for	Main advantage	Main tradeoff
Rear-engine riding mower	Small to medium lawns	Maneuverability and visibility	Not ideal for steep slopes or very rough ground
Lawn tractor (front-engine)	Medium to large lawns	More attachments and heavier-duty options	Larger turning radius
Zero-turn mower	Larger open areas with obstacles	Fast trimming and tight turns	More maintenance points and higher cost

Why it matters

Rear-engine mowers are popular when you want the comfort of a rider but still need to weave around obstacles and store the machine easily. For safe operation details (especially slope limits, starting interlocks, and mowing patterns), follow the guidance in the 247204120 owner's manual.

Tips to get the most out of a rear-engine mower

• Mow when grass is dry to reduce clumping and improve cut quality
• Keep the deck clean to maintain airflow and discharge performance
• Check belt condition if you notice slipping or uneven cutting
• Verify tire pressure regularly; it affects cut height and tracking
• Use sharp blades; dull blades tear grass and can make the mower feel underpowered

For a riding mower, the “best” engine is the one that matches your yard size and workload: a proven V-twin with strong parts support for weekly mowing, or a commercial-grade engine if you mow for hours at a time. For Craftsman model 247204120, use the engine specifications and maintenance schedule in the 247204120 owner's manual to choose the right replacement or tune-up approach.

How we pick the best engine for your use

• Yard size and terrain: hills and thick grass need more torque and cooling capacity.
• Hours per week: occasional mowing favors value; frequent mowing favors durability.
• Serviceability: easy oil changes, accessible air filter, and common wear parts.
• Fuel system type: carbureted engines are common; fuel-injected engines handle storage and temperature swings better.
• Parts availability: filters, plugs, starter components, and belts should be easy to source.

Quick comparison: what “best” means in practice

Your situation	Engine traits that perform best	What to prioritize
Typical residential mowing	Reliable single or V-twin, good cooling	Maintenance schedule, parts support
Heavy grass, hills, towing	Higher torque V-twin, robust charging system	Cooling, torque, air filtration
Long run times (near-commercial)	Commercial-grade build, heavy-duty internals	Longevity, service intervals

What to check before you decide

Use your mower’s exact engine model and spec numbers (often on the engine label) and confirm these items in the 247204120 owner's manual:

• Crankshaft size and length (must match your pulley/clutch setup)
• Mounting pattern (bolt spacing and base style)
• Charging output (for headlights, PTO clutch, and battery charging)
• Throttle/choke linkage compatibility
• Exhaust routing and heat shielding

Why it matters

An engine that is “best” on paper can still be a poor fit if the crankshaft, charging system, or controls do not match your Craftsman 247204120. Matching the specs prevents belt misalignment, starting issues, and premature wear on drivetrain and deck components.

The Craftsman model 247204120 identifies a specific rear-engine riding mower configuration, but the model number alone does not map to one single “year”. We use the mower’s product ID label information (and sometimes the engine model/type/code) to pinpoint the exact production date; the best reference for label locations and identification is the owner's manual.

How to find the build date on a Craftsman 247204120

Check these common spots for the product ID label (often called a model/serial tag):

• Under the seat pan or on the seat support
• On the rear frame near the hitch plate
• Along the left or right side of the frame rail
• Near the footrest or floorboard area
• Under the hood area (if equipped)

Once you find it, record:

• Serial number (most helpful)
• Any date code printed on the label
• The engine model/type/code (often on the engine shroud)

What information actually determines the “year”

For riding mowers, the “year” is typically tied to the serial number range or a date code, not the marketing name.

What you have	What it tells us	How useful it is
Model number (247204120)	Family/configuration	Medium
Serial number	Production run and date range	High
Engine model/type/code	Engine build date reference	Medium
Parts diagram match	Confirms correct version for parts	High

Why it matters

Getting the correct year or production range helps you match the right belts, hardware, and drivetrain parts for your exact build. For example, this model’s parts list includes wear items like the lawn tractor ground drive belt 954-04317A and the lawn tractor blade drive belt 954-04033A, which can vary by production run.

Quick tips before ordering parts

• Match parts by model plus serial whenever possible
• Compare belt width and length to your old belt before installing
• Replace missing fasteners with the correct size (for example, a cotter pin 714-04040)
• Use the diagrams to confirm pulley routing and shield placement

If you want the fewest problems over time, we recommend focusing less on brand hype and more on proven design and maintenance. For a rear-engine rider like Craftsman model 247204120, the most reliable choice is the mower that matches your yard size, uses a simple drive system, and is maintained on schedule using the specs in the 247204120 owner's manual.

What “least problems” usually means (and what to shop for)

Reliability comes from fewer failure points, good cooling, and correct belt and deck setup. When comparing riding mowers, prioritize:

• Hydrostatic drive (smooth, fewer shifting issues than manual transaxles)
• V-twin engine (typically smoother and less vibration than many single-cylinder designs)
• Easy belt access and correct belt routing (prevents premature belt wear)
• Greaseable deck spindles/mandrels (when equipped)
• Strong dealer and parts support (so routine wear parts are easy to get)

Practical reliability checklist for a mower like 247204120

Even a solid mower becomes “problem-prone” when belts slip, pulleys seize, or safety switches get bypassed. These are the most common reliability drivers we see:

• Keep the deck clean under the housing to prevent corrosion and belt heat
• Replace worn belts before they start slipping or glazing
• Fix vibration early (often a spindle/mandrel or blade issue)
• Keep battery terminals tight and clean; weak voltage causes hard-start complaints
• Use fresh fuel and a clean fuel system to avoid no-start and surging

Parts that commonly affect “problem rate”

On Craftsman 247204120, recurring issues often trace back to normal wear items. If symptoms match, these parts are common fixes:

• Slipping or no movement: lawn tractor ground drive belt 954-04317A
• Blades not engaging or poor cut: mtd lawn tractor blade drive belt 954-04033A
• Clicking or no crank: lawn tractor starter solenoid 725-06153
• Uneven cut or deck noise: lawn tractor mandrel assembly 918-04822A

Quick comparison: what tends to break less

Feature	Tends to have fewer problems	Tends to have more problems
Drive type	Hydrostatic	Worn manual linkages, misadjusted belts
Deck condition	Clean, level, sharp blades	Packed grass, bent components
Electrical	Clean connections, good battery	Corroded terminals, weak battery
Maintenance	On-schedule oil and belt checks	Deferred service until failure

Why it matters

Most “unreliable mower” complaints are really maintenance and wear problems that show up as belt slip, hard starting, poor cut quality, and vibration. Choosing a mower with a simpler layout and then maintaining it to spec delivers the fewest headaches.
