What engine does Craftsman riding mower use?
For Craftsman lawn tractor model 917288220, the operator’s manual identifies it as a 20.0 HP (as rated by the engine manufacturer), 42-inch mower with an electric start and automatic transmission; the manual does not specify the engine brand in the excerpted specs. For exact engine make and model, use the ID and specification section in the 917288220 owner's manual.
How to identify the exact engine on 917288220
Use these quick checks to match the correct engine parts (air filter, spark plug, fuel filter, starter, carburetor):
- Look for the engine ID label on the blower housing, valve cover, or near the starter
- Record the model, type, and code (common on Briggs and Stratton) or the model/spec (common on other engines)
- Compare the ID to the engine information listed in the 917288220 owner's manual
- Use the engine ID when ordering ignition and starting parts such as the lawn tractor starter solenoid 582042802
- If the tractor cranks but will not start, verify fuel quality and choke/throttle settings before replacing parts
What we can confirm from the manual (model-specific)
The manual for this tractor family (917.28822) calls out these key specs:
| Spec item | What the manual shows |
|---|---|
| Horsepower rating | 20.0 HP (engine manufacturer rating) |
| Mower deck size | 42-inch |
| Starting | Electric start |
| Transmission | Automatic |
Why it matters
The engine brand and exact engine model determine the correct maintenance and repair parts. Using the tractor model number alone can point you to chassis and deck parts, but the engine ID is what prevents ordering the wrong tune-up items.

How much does it cost to replace a riding lawn mower engine?
For the Craftsman riding lawn tractor model 917288220, a full engine replacement typically costs about $800 to $2,500 installed (engine plus labor). The biggest cost drivers are the engine type, whether the replacement is a direct-fit, and the shop labor rate.
Typical cost breakdown
Here is what we see most often for a front-engine riding mower engine swap:
- Engine (new): $500 to $1,800
- Labor: $300 to $700 (often 4 to 8 hours)
- Shop supplies and small parts: $25 to $100
- Optional add-ons: battery, belts, blades, fuel line, tune-up parts
| Cost item | Typical range | Notes |
|---|---|---|
| Engine | $500 to $1,800 | Direct-fit engines cost less to install than conversions |
| Labor | $300 to $700 | More if rusted fasteners or wiring issues slow the job |
| Misc. parts | $25 to $100 | Clamps, hardware, oil, filter, spark plug |
When replacement makes sense (and when it does not)
Engine replacement is usually worth it when the tractor is otherwise in good shape (deck, transmission, steering) and you want to keep the same machine.
Replacement is less attractive when:
- The mower deck has major spindle or mandrel wear (vibration, noisy bearings)
- The drive system has ongoing belt or pulley problems
- The wiring harness is damaged or heavily corroded
- The tractor has multiple high-dollar needs at the same time
Checks to do before buying an engine
Many “bad engine” symptoms are caused by fuel, ignition, or safety circuits. The troubleshooting chart in the 917288220 owner’s manual covers common no-start and power-loss causes like stale fuel, dirty fuel filter, loose spark plug wire, and wiring issues.
- Confirm the battery is strong and connections are clean
- Verify fresh gasoline and a clean fuel filter
- Check spark plug condition and spark plug wire fit
- Inspect wiring for looseness or damage
- Make sure safety interlocks are working (seat and brake)
Why it matters
An engine swap is one of the highest-cost repairs on a riding mower. Doing a quick diagnostic first helps you avoid replacing the engine when the real issue is a fuel delivery problem, ignition problem, or a safety interlock shutting the engine down.

What year was Craftsman 917288220 made?
Craftsman model 917288220 (also shown in the operator manual as 917.28822) was manufactured across multiple production runs, not as a single one-year model. The exact year for your tractor is identified on the serial number and product label on the machine; use the 917288220 owner's manual to confirm the label location and how to record it.
How to find the build year on the tractor
On most Craftsman front-engine lawn tractors, the model and serial number label is located under the seat or on the rear fender area near the seat pan.
- Park on a flat surface, set the parking brake, and remove the key
- Tilt the seat forward and look for a white or silver product label
- Write down the model number (917288220) and the serial number exactly
- If the label is dirty, wipe it gently so all digits are readable
- Use the serial number to determine the production date range for that specific unit
What the manual tells us (and what it does not)
The operator manual confirms the tractor family and configuration (20.0 HP, 42-inch mower deck, electric start, automatic transmission) and lists the model as 917.28822, which corresponds to 917288220. That manual format is typically used across more than one year of production.
Quick reference
| Item | What it helps with | Where to look |
|---|---|---|
| Model number | Identifies the tractor series | Product label, manual cover |
| Serial number | Pins down the build year/run | Product label on tractor |
| Engine model/type | Helps match tune-up parts | Engine shroud label |
Why it matters
Knowing the exact build year helps us match the correct parts and diagrams for your specific production run, especially for wear items like deck blades, belts, and mandrel components.
If you are also matching deck parts, these are common 42-inch deck items used on this model family: lawn tractor mandrel housing 587819701, lawn tractor drive belt 532125907.

Is it worth replacing a lawn mower engine?
Replacing the engine on your Craftsman lawn tractor model 917288220 is worth it when the tractor is otherwise in solid shape (deck, transmission, steering) and the total repair cost stays well below the price of a comparable replacement mower. Use the 917288220 owner's manual to confirm maintenance and troubleshooting steps before committing to an engine swap.
Quick decision checklist
- The deck and frame are not rusted through or cracked
- The transmission and drive system still pull strongly (no slipping or loss of drive)
- The electrical system is in good condition (battery cables, wiring, switches)
- You can source the correct engine and any required pulleys, wiring, and mounting hardware
- The total cost (engine + labor + incidentals) is under about 50% of the mower’s current value
What to check first (often cheaper than an engine)
Before replacing an engine, we recommend ruling out common no-start and poor-running causes listed in the troubleshooting guidance:
| Symptom | Common non-engine causes | Typical fix |
|---|---|---|
| Clicks but won’t start | Weak battery, dirty terminals, bad solenoid | Charge/clean connections; replace solenoid if needed |
| Cranks but won’t start | Stale fuel, dirty fuel filter, spark plug issue | Fresh fuel; replace filter; service spark plug |
| Loss of power | Dirty air filter, clogged muffler, low oil | Clean/replace filter; service muffler; change oil |
| Excessive vibration | Worn/bent blade, bent mandrel | Replace blade; inspect mandrel and housing |
If you’re chasing a click/no-crank condition, the lawn tractor starter solenoid 582042802 is a common wear item on this model family.
Why it matters
An engine replacement can restore years of service, but it only pays off if the rest of the tractor is safe and reliable. The manual also emphasizes keeping debris off hot engine/exhaust parts and maintaining tight fasteners, which helps prevent repeat failures after a major repair.
