Craftsman 917288031 tractor Parts

For the Craftsman lawn tractor associated with model family 917288031, the operator documentation identifies the tractor as Model No. 917.28803. You can usually find that same model identifier on a product label on the tractor frame under the seat; verify the characters match the format shown in the 917.28803 operator's manual.

Start with the spots most commonly used on this platform:

• On the tractor frame directly under the seat (lift the seat)
• On the underside of the seat pan
• On the frame near the seat mounting area
• On the rear frame area near the fender support

Craftsman 917-series numbers are sometimes printed with punctuation (like 917.28803) and sometimes shown without dots or with extra suffix digits in parts listings. When ordering parts, we recommend matching what you see on the tractor label first, then cross-referencing it to the parts listing.

Even when the model number is clear, these details can help confirm the correct diagrams and replacements:

• Model number exactly as printed (including dots)
• Any product number shown on the same label
• Engine identification numbers (model/type/code) from the engine label

Small model-number formatting differences can point to different deck setups or revisions, which affects fit for items like a blade drive belt or blades.

Replacing the engine on your Craftsman 917288031 can be worth it when the tractor’s deck, steering, and transaxle are in good condition and you’ve confirmed true internal engine failure. Start by using the troubleshooting chart in the 917288031 operator's manual to rule out simpler causes.

The manual’s troubleshooting section covers “will not start,” “hard to start,” and “loss of power.” Before pricing an engine, check these common service items:

• Fresh fuel (the manual notes fuel should generally be used within about 30 days)
• Clean air filter and clear air screen/cooling fins
• Good spark plug and tight spark plug wire connection
• Clean fuel filter and unrestricted fuel flow
• Correct oil level and on-schedule oil changes

If the tractor runs but bogs when you engage the mower deck, the engine may be fine and the deck may be overloading it.

A slipping belt, binding pulley, or dull blade can drag the deck and make the engine struggle.

Engine replacement is most practical when you are not stacking multiple major repairs.

• Good candidate: solid deck shell, tight steering, transaxle drives smoothly
• Poor candidate: slipping transaxle, severe deck rust-through, repeated electrical failures
• Diagnose first: no-start or power-loss symptoms that match routine maintenance items

An engine swap is a high-effort, high-cost repair. Verifying the failure first helps you avoid replacing an engine when the real issue is fuel, ignition, airflow, or mower-deck drag.
