Craftsman 917270631 tractor Parts

“Craftsman 6.75” by itself is not a single model number; it describes the engine horsepower used on many different Craftsman walk-behind mowers. The model number you need is printed on the mower’s model tag, and it will look like a 9-digit number (often starting with 917). For reference, our page here is for Craftsman tractor model 917270631, which is a different product type than a 6.75-hp walk-behind mower.

Check the model tag first; that tag is the only reliable way to match the correct parts list.

• Look on the rear of the mower deck near the discharge chute
• Check under the seat area on self-propelled models with a rear cover
• Look near the engine mounting area on top of the deck
• If the tag is dirty or faded, wipe it clean and use a flashlight at an angle

Most Craftsman walk-behind mower model numbers are 9 digits and commonly start with 917. You may also see a format with a dot (example: 917.XXXXXX).

Parts like belts, blades, wheels, and pulleys vary by deck size and drive system, even when the engine rating is the same. Using the exact model number prevents ordering the wrong blade or ground drive belt.

If you are actually working on Craftsman 917270631 (42-inch deck tractor), the owner's manual lists the model and includes parts diagrams. Common deck-related parts shown for this tractor include the husqvarna lawn tractor mulching blade, 21-in 532134149 and the lawn tractor drive belt 532144200.

On Craftsman lawn tractors like model 917270631, the model number identifies the tractor family, but the build year is determined from the product’s serial number/date code on the ID label. Use the date-code format shown in the owner's manual section for identification and recordkeeping.

We typically see the ID label in one of these spots on a front-engine Craftsman rider:

• Under the seat pan or on the seat bracket area
• On the rear fender pan near the seat
• On the frame rail (left or right side)
• Near the engine compartment on the chassis

Many Craftsman-built riding mowers use a date code embedded in the serial number that reads as MMDDYY (month, day, year). When your label uses that format:

• First 2 digits = month
• Next 2 digits = day
• Last 2 digits = year

Some labels use a different pattern (letters mixed with numbers, or a longer code). In that case, we use these checks to narrow it down:

• Confirm the model number is 917270631 (it should match exactly)
• Compare the tractor’s decal set and equipment to the parts diagrams in the manual
• Match common wear parts (deck belt, blades, mandrel parts) to the parts list for your model

If you are servicing the mower deck while you identify the build date, common deck-related parts for this model include the lawn tractor drive belt 532144200 and the husqvarna lawn tractor mulching blade, 21-in 532134149.

Knowing the correct build year helps us match the right parts diagram and avoid ordering the wrong belt, blade, mandrel assembly, or steering components for your Craftsman tractor.

Replacing the engine on a Craftsman front-engine lawn tractor like model 917270631 typically costs $260 to $1,800 for the engine plus labor. Most riding-mower engine swaps are billed at about 4 to 8 labor hours, with the total driven mainly by engine price and any extra parts needed.

• Engine cost: new vs. rebuilt, horsepower, crankshaft size, and mounting pattern
• Labor hours: removal, transfer of pulleys and wiring, and setup
• Extra parts and supplies: oil, filter, spark plug, fuel line, clamps, hardware
• Related wear found during teardown: belts, pulleys, wiring, battery cables
• Setup and testing: throttle/choke linkage adjustment and safety checks

The troubleshooting chart in the 917270631 owner's manual focuses first on starting-system checks that often solve a “clicks but won’t start” complaint.

• Recharge or replace the battery; clean and tighten terminals
• Check the fuse and inspect wiring connections for looseness or corrosion
• Verify the brake, seat, and PTO safety interlock switches are operating
• Test the starter solenoid and starter motor

If the tractor clicks but won’t crank, a failed solenoid is a common fix; this model’s parts list includes the solenoid 532146154 (part number 145673).

An engine replacement is one of the highest-cost repairs on a riding mower. Confirming the battery, wiring, and solenoid first can prevent replacing a good engine and can restore reliable starting faster.

Craftsman riding mower model 917270631 uses a Briggs & Stratton 2-cylinder (V-twin) gasoline engine. The exact engine model, type, and code are printed on the engine ID label; match that information to the specifications section in the 917270631 owner's manual.

Use the engine ID label so you get the right tune-up specs and parts.

• Locate the engine model/type/code label (commonly on the valve cover, blower housing, or near the starter)
• Write down the full model/type/code exactly as shown
• Confirm the tractor model tag reads 917270631
• Use the engine ID when selecting spark plug, air filter, fuel filter, and oil specs
• Keep the engine ID with your maintenance records for faster parts matching

A V-twin riding mower engine typically has stronger torque and smoother operation than a single-cylinder; it also has a few extra maintenance touchpoints.

• Expect two spark plugs (one per cylinder)
• Air filtration and cooling-fin cleaning are critical to prevent overheating
• Battery, cables, and starter circuit condition strongly affect starting performance

If the engine clicks but does not crank, the starter solenoid is a common checkpoint on riding tractors.

• Solenoid 532146154

The engine’s model/type/code determines the correct maintenance parts and specifications (oil type and capacity, spark plugs, air filter, and some electrical components). Matching by engine ID prevents ordering the wrong parts.
