Craftsman 917273664 lawn tractor Parts

The Craftsman lawn tractor model 917273664 uses a low-emission engine (as specified in the owner’s manual) and is built as a 25.0 HP, 48-inch mower configuration. For the exact engine manufacturer and model designation, match the engine ID label to the specifications in the 917273664 owner's manual.

We recommend confirming the engine make and model from the engine itself, then cross-checking it with the manual’s product specifications and parts information.

• Turn the ignition to STOP, remove the key, and let the engine cool.
• Lift the hood and locate the engine ID label (often on the blower housing, valve cover, or near the starter).
• Record the engine model, type, and code (or serial number).
• Compare those numbers to the engine section in the 917273664 owner's manual.
• Use the engine ID when ordering tune-up parts (air filter, spark plug, fuel filter) to avoid mismatches.

The owner’s manual for Craftsman 917273664 identifies the tractor configuration and key operating characteristics.

Engine families can vary within the same tractor model over production runs. Using the engine ID label (not just “Craftsman 917273664”) ensures the correct maintenance parts and avoids fit issues.

For the Craftsman lawn tractor model 917273664, the engine manufacturer depends on the specific engine installed on the tractor; Craftsman has commonly used engines from Briggs & Stratton, Kohler, and Kawasaki across different riding mower and tractor models. The sure way to identify yours is to match the engine brand and model shown on the engine ID label and in the 917273664 owner's manual.

Check these spots on the tractor and engine:

• Engine shroud or valve cover for a brand badge (Briggs & Stratton, Kohler, Kawasaki)
• Engine ID label (usually on the blower housing, valve cover, or near the starter)
• Owner documentation and parts diagrams in the 917273664 owner's manual
• Decals and labels on the hood or dash (helpful, but the engine ID label is the best proof)

Most riding mower engine labels include:

• Manufacturer name (brand)
• Engine model
• Type/spec code (common on Briggs & Stratton and Kohler)
• Serial number

Use those numbers when ordering tune-up parts (air filter, oil filter, spark plug) so you get an exact match.

The engine maker determines the correct maintenance parts and service specs (spark plug type, oil capacity, air filter style). Matching by engine ID prevents ordering the wrong parts even when the tractor model number is correct.

Yes, it’s worth replacing the engine on your Craftsman lawn tractor model 917273664 when the tractor’s deck, frame, steering, and transmission are still solid and the total engine swap cost stays well below the cost of a comparable replacement tractor. If the tractor also needs major drivetrain or deck repairs, replacement usually makes more sense.

• The mower deck is structurally sound (no major rust-through or cracks)
• The transmission drives normally (no slipping, no loss of motion)
• Steering and front axle are tight enough to track straight
• You can do basic maintenance safely (engine off, cooled down)
• The engine failure is isolated (not multiple systems failing at once)
• You can source the correct engine and mounting hardware for this chassis

Use this simple comparison to decide where your money goes.

Many “bad engine” symptoms are actually starting or safety issues. Check these first:

• Battery and cable connections (clean and tight)
• Safety interlock operation (brake, seat, PTO)
• Fuel delivery (clogged in-line fuel filter can restrict flow)
• Spark plug condition (often replaced at the start of each mowing season or every 100 hours)
• Cooling and debris buildup (blocked screens and dirty cooling fins can cause overheating damage)

For model-specific maintenance intervals and safety guidance, follow the 917273664 owner’s manual.

An engine swap can extend the life of a good Craftsman chassis and mower deck, but it only pays off when the rest of the tractor is reliable. The manual’s maintenance items (spark plug, fuel filter, cooling system cleaning) also help protect your investment after the repair.

For a Craftsman lawn tractor like model 917273664, a full engine replacement typically costs $260 to $1,800 installed, depending on the engine, labor rates, and whether related items (battery cables, belts, pulleys) also need service. Plan on about 6 hours of labor for a riding mower engine swap.

• Engine price: the biggest variable; OEM-style replacements cost more than some aftermarket options.
• Labor rate and shop minimums: small-engine shops often bill a flat rate or hourly.
• Extra parts found during teardown: worn belts, pulleys, wiring, or mounts can add cost.
• Fuel system cleanup: stale fuel or debris can require tank and carburetor cleaning.
• Pickup/delivery: transport fees can be significant for riding mowers.

Replacement is usually the better value when the engine has low compression, a thrown rod, severe oil consumption, or major internal damage. Repair is often smarter for starter, solenoid, carburetor, or wiring issues.

• If the engine clicks but won’t crank, follow riding lawn mower engine clicks but doesnt turn over video.
• If it spins but won’t start, use riding lawn mower engine spins but wont start video.
• For model-specific safety and service cautions (key removal, blade shutdown, and repair precautions), follow the 917273664 owner’s manual.

A correct engine match (shaft size, mounting pattern, charging system) prevents repeat failures and protects the mower’s PTO, deck drive belt, and electrical system from damage.
