Craftsman 917273764 lawn tractor Parts

Replacing the engine on a Craftsman lawn tractor model 917273764 typically costs $900 to $2,500 total (engine plus labor). The biggest cost drivers are whether you install it yourself, the exact engine spec, and any extra parts needed to restore safe starting and blade operation.

Typical cost breakdown

• Engine (new replacement): $600 to $1,800
• Labor (shop install): $300 to $900
• Pickup/delivery (if used): $50 to $200
• Optional add-ons: $25 to $250 (belts, battery, tune-up parts)

Scenario	What you pay for	Typical total cost
DIY swap	Engine + your time	$600 to $1,900
Shop install	Engine + labor	$900 to $2,500
“While we’re in there” refresh	Engine + labor + wear items	$1,050 to $2,750

What usually adds cost (and prevents repeat failures)

When an engine is replaced, we also check common no-start and poor-running causes listed in the troubleshooting guidance, because they can look like “bad engine” symptoms.

• Weak battery or corroded terminals
• Damaged wiring, ignition switch, solenoid, or starter
• Stale fuel, clogged fuel filter, dirty air filter
• Low oil level or overdue oil change
• Safety interlock issues (seat/brake/attachment clutch)

For model-specific procedures and safety checks, use the 917273764 owner’s manual.

When engine replacement makes sense

Replace the engine if:

• The engine has internal damage (knocking, seized crank, heavy smoke)
• Compression is low and a rebuild is not cost-effective
• The tractor is otherwise in good shape (deck, transaxle, steering)

Consider repair instead if:

• The engine cranks but will not start (often fuel, spark, or safety circuit)
• The engine clicks but will not turn over (often battery or starter circuit)

A fast way to narrow this down is to follow riding lawn mower engine spins but wont start video or riding lawn mower engine clicks but doesnt turn over video.

Why it matters

A correct diagnosis saves money; many “engine replacement” quotes are avoided by fixing the starting circuit, fuel delivery, or safety interlocks first. If you do replace the engine, budgeting for small wear items helps protect the new engine and improves reliability.
