Craftsman 917273758 tractor Parts

For a Craftsman riding tractor like model 917273758, a full engine replacement typically runs $800 to $2,500 installed (engine plus labor). The total depends on the engine type, whether the wiring and fuel system need updates, and shop labor time.

What drives the total cost

• Engine price: Most replacement riding mower engines fall in the $500 to $1,800 range.
• Labor time: Commonly 4 to 8 hours for a riding mower engine swap.
• Extra parts: Belts, pulleys, wiring, fuel filter, and mounting hardware can add cost.
• Shop rates: Local labor rates vary widely.
• Condition of the tractor: Rusted fasteners, damaged harnesses, or worn drive components increase time.

Typical cost breakdown (installed)

Cost item	Typical range	Notes
Replacement engine	$500 to $1,800	Biggest variable (brand, horsepower, shaft specs)
Labor	$300 to $900	Often 4 to 8 hours
Misc. parts and supplies	$25 to $200	Fuel line, clamps, oil, filter, hardware
Estimated total	$800 to $2,500	Most common real-world range

Before you replace the engine, check these common “no start” causes

Many tractors get quoted for an engine when the real issue is electrical, fuel, or safety interlocks.

• Battery condition and cable connections
• Safety interlock system (seat switch, brake/clutch switch, PTO/attachment clutch)
• Fuel quality (old fuel or water in fuel)
• Spark plug and plug wire connection
• Air filter and cooling fins/screens (overheating and poor running)

For model-specific operating and maintenance checks, use the 917273758 owner’s manual.

Why it matters

An engine replacement can cost close to the value of an older riding mower. Pricing the job with the correct engine specifications (shaft diameter/length, crank orientation, charging output) helps avoid fitment problems and repeat labor.

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 example, 917.273758 for model 917273758) when searching parts and manuals. On most Craftsman riding tractors, the tag is on the frame under the seat area.

Where to find the model and serial number on model 917273758

Check these common locations (clean off grass and dirt so the tag is readable):

• On the frame under the seat (lift the seat and look down at the chassis rails)
• On the underside of the seat pan
• Near the rear fender or seat bracket area
• On a sticker or metal plate close to the transaxle area

For diagrams and model identification details tied to your tractor, use the 917273758 owner's manual.

How to use the model number to look up the right parts

Once you have the tag information, match it exactly (including dots and any extra digits/letters). Then:

• Search using the full model number: 917273758
• Use the parts diagrams to confirm the part fits your exact configuration
• Match the part description and hardware style (nuts, clips, pulleys) before ordering
• If you are replacing deck parts, confirm deck size (this model is shown as a 42-inch mower deck in the manual)

Quick lookup checklist

What you have	What to type for lookup	Why it matters
Model tag shows 917.273758	917273758 (or 917.273758)	Ensures correct parts diagrams and revisions
Serial number	Keep for reference	Helps identify production run differences

Why it matters

Craftsman tractors often share similar frames and decks across multiple models. Using the exact model number prevents ordering a blade, belt, or transaxle part that looks right but mounts differently.

For Craftsman model 917273758, the owner’s manual identifies it as an 18.0 HP front-engine riding lawn tractor with a 42-inch mower deck; the manual does not specify the engine manufacturer in the excerpted pages, so we use the manual’s horsepower rating as the reliable identifier. See the 917273758 owner's manual for the engine section and maintenance specs.

How to identify the exact engine on your 917273758

The most accurate way to confirm the engine brand and model is to read the engine ID label on the engine itself.

• Lift the hood and locate the engine label (often on the blower housing, valve cover, or near the starter)
• Write down the engine model, type, and code (or serial)
• Compare those numbers to the engine section in the manual
• Use the engine ID when ordering tune-up items (spark plug, air filter, fuel filter)
• If the label is dirty, wipe it gently so the numbers are readable

What we can confirm from the manual (model-specific)

Based on the documentation for model 917273758:

Item	What the manual shows
Tractor model	917.273758
Engine rating	18.0 HP
Deck size	42 in
Starting system	Electric start

Why it matters

Craftsman tractors can use different engine families across similar-looking models. Using the engine ID label prevents ordering the wrong ignition parts, filters, or carburetor-related items, and it helps match the correct maintenance intervals.

Related parts you may replace during engine and mowing maintenance

These are common wear items on this tractor platform:

• Blades (for cut quality and vibration)
• Deck drive and ground drive belts
• Mandrel components (if you hear grinding or see wobble)

If you are refreshing the deck at the same time, a correct-fit blade option is the lawn tractor 42-in deck high-lift blade 532138971.

The Craftsman riding mower model 917273758 is identified in the 917273758 owner's manual as an 18.0 HP, 42-inch mower with electric start and a 6-speed transaxle. The manual excerpt provided does not list a specific manufacture year, so we use the model and product ID label on the tractor to match the exact production date.

Where to find the year on model 917273758

On Craftsman tractors, the build date is typically tied to the product identification label rather than printed in the owner’s manual.

• Look under the seat pan area and seat bracket
• Check the frame rail near the engine compartment
• Look near the rear fender or transaxle area
• Record the model number and any serial number/date code
• Use the exact characters as shown (including dots or dashes)

Quick ID checklist (what we know from the manual)

From the documentation for Craftsman 917273758, we can confirm these model identifiers:

Item	What to look for	Why it helps
Engine rating	18.0 HP	Confirms you are matching the correct tractor family
Deck size	42-inch mower deck	Ensures the correct deck and blade system
Starting system	Electric start	Helps distinguish from similar manual-start units
Transmission	6-speed transaxle	Narrows down the correct configuration

Why it matters

The exact year affects parts lookups and compatibility for common repairs like mower deck service, belts, and blades. For example, this model’s 42-inch deck uses specific blade options such as the husqvarna lawn tractor mulching blade, 21-in 532134149 and the lawn tractor 42-in deck high-lift blade 532138971, and the correct match depends on the tractor’s exact configuration.
