Craftsman 917288050 tractor Parts

To look up your Craftsman model number, we recommend finding the model and serial tag on the tractor first, then using that exact model number (for this page, 917288050) to match the correct parts list and 917288050 owner's manual. On most riding tractors, the tag is under the seat area.

Where to find the model and serial number tag

On Craftsman riding mowers and lawn tractors, the ID tag is commonly located in one of these spots:

• On the frame under the seat (lift the seat and look on the chassis rails)
• On the underside of the seat pan
• Near the rear fender or seat bracket area
• Occasionally near the engine compartment on the frame

How to use the model number once you find it

After you locate the tag, use these steps to ensure you pull the right diagrams and parts:

• Write the model number exactly as shown (include all digits)
• Use the model number to select the matching parts diagrams for your tractor
• Use the serial number to confirm production variation when ordering parts
• Cross-check key specs (deck size, transmission type, engine HP rating) in the manual

Quick check: model number vs. serial number

Item	What it does	Example for this tractor
Model number	Identifies the exact tractor design and parts breakdown	917288050
Serial number	Identifies the production run and can affect part fit	Varies by unit

Why it matters

Craftsman tractors often have similar-looking frames and mower decks across multiple model numbers. Using the exact model number helps us match the correct blade, belt, mandrel, and electrical parts so you avoid returns and downtime.

A tractor engine is built from a few core systems: the rotating assembly (crankshaft, pistons, connecting rods), the valve train (camshaft, valves), and the support systems (fuel, ignition, lubrication, cooling, and exhaust). For Craftsman model 917288050, we use the 917288050 owner's manual to match parts and service steps to your exact engine setup.

Main tractor engine parts (what they do)

• Cylinder block and cylinder head: the main structure where combustion happens
• Pistons, piston rings, and wrist pins: compress the air-fuel mix and transfer force to the crankshaft
• Connecting rods and crankshaft: convert piston motion into rotating power
• Camshaft, valves, valve springs, and lifters: control air intake and exhaust flow
• Gaskets and seals: keep compression, oil, and fuel where they belong
• Lubrication system (oil pump, oil filter, sump): reduces wear and carries heat away
• Fuel and ignition (carburetor or injection, fuel pump, spark plug, ignition module): starts and sustains combustion

Support systems you should include in an “engine parts” list

Even though they bolt around the engine, these are essential to how it runs:

• Starter and charging system (starter motor, solenoid, alternator/stator)
• Cooling system (air shrouds and fins on many lawn tractors; some engines use liquid cooling)
• Exhaust system (muffler, exhaust pipe)

Quick breakdown by system

System	Key parts	What you notice when it fails
Mechanical	pistons, rings, crankshaft, bearings	low power, knocking, heavy smoke
Valve train	camshaft, valves, guides	hard starting, backfiring, poor compression
Fuel/ignition	carburetor, spark plug, coil	no-start, surging, stalling
Lubrication	oil pump, filter, seals	rapid wear, overheating, oil leaks

Why it matters

Knowing which system a symptom belongs to speeds up troubleshooting and helps you order the right Craftsman parts the first time. It also supports safe operation practices called out in the manual (controls, starting, and operating guidance).

The Craftsman riding lawn mower model 917288050 uses a 17.5 HP (as rated by the engine manufacturer), low-emission gas engine; it’s paired with a 42-inch mower deck and an electric start system. For the exact operating details and specifications, use the 917288050 owner's manual.

What we can confirm for model 917288050

From the operator’s manual for this tractor, these are the key engine-related identifiers:

• 17.5 HP engine rating (manufacturer-rated)
• Low-emission engine design (operates differently than some older engines)
• Electric start
• 42-inch mower deck
• 6-speed transaxle (drive system)

Quick spec snapshot

Item	What you’ll see on 917288050
Engine rating	17.5 HP (manufacturer-rated)
Emissions design	Low-emission engine
Starting system	Electric start
Mower deck size	42-inch
Transmission	6-speed transaxle

Why the engine type matters

Engine design affects how you start, run, and maintain the tractor. A low-emission engine can have different starting behavior and warm-up needs than older designs, so following the correct throttle and choke procedure helps prevent hard starting and poor performance.

Helpful operating tips (engine and drive)

These basics help protect the engine and drivetrain during normal mowing:

• Read the safety and starting steps before the first start-up (especially for low-emission engines).
• Run the engine at full speed (fast) for best mower performance.
• Bring the tractor to a complete stop before shifting gears to reduce transaxle wear.
• Avoid letting the tractor idle on grass for long periods; hot exhaust can brown turf.
• Do not leave the ignition switch in any position other than STOP when parked; it can drain the battery.

Craftsman model 917288050 identifies the tractor configuration (17.5 HP, 42-inch mower, 6-speed transaxle), but the exact build year is determined from the serial number/date code on your tractor’s ID decal, not from the model number alone. Use the identification section in the 917288050 owner's manual to locate and interpret that information.

How to find the build date on a 917288050

Look for the model and serial information on the tractor, then use it to determine the manufacturing date.

• Check under the seat, along the frame rail, or near the rear fender for the ID decal
• Record the model number (917288050) and the full serial number/date code exactly
• Clean the decal area so every character is readable
• Compare what you wrote down to the identification and service sections in the manual
• Use the serial information when ordering parts to avoid mismatches between production runs

What the manual cover tells you (and what it does not)

The operator’s manual confirms the model and major specs, but it does not assign a single “model year.”

Item shown in manual	What it helps with	What it does not confirm
Model No. 917.28805 (917288050)	Correct manual and parts diagrams	Exact manufacturing year
17.5 HP, 42-inch mower	Deck size and engine class	Exact engine model/date
6-speed transaxle	Drivetrain type for parts matching	Production month/year

Why the year matters for parts

Craftsman tractors can have mid-run changes; the serial number keeps you from ordering the wrong version.

Common items that vary by production run include:

• Deck hardware (mandrels, pulleys, blade hardware)
• Electrical starting components and wiring routing
• Steering and axle hardware
• Brake linkage parts and springs

Example deck parts often replaced

If you are servicing the 42-inch deck, these model-matched parts are commonly used:

• Lawn tractor mandrel housing 587819701
• Lawn tractor 42-in deck high-lift blade 532138971
