Craftsman 917271740 tractor Parts

Yes, replacing the engine on your Craftsman 917271740 front-engine lawn tractor is worth it when the mower deck, transmission, steering, and frame are in solid shape and the total engine swap cost stays well below the cost of a comparable replacement tractor. If the tractor has multiple worn systems, replacement usually makes more sense.

• The deck shell is not rusted through and the spindles are not loose or seized
• The transmission drives smoothly forward and reverse without slipping
• Steering is tight enough to track straight (no severe play)
• You can do the work (or pay labor) without exceeding your budget
• You plan to keep the tractor for several more seasons

Engine replacement is a bigger project than typical maintenance, so we recommend comparing total cost, not just the engine price.

If you are investing in an engine, it is smart to refresh wear items that affect cut quality and drivability.

• Lawn tractor ground drive belt, 1/2 x 82-in 532140294 if the tractor slips, squeals, or the belt is glazed
• Husqvarna lawn tractor mulching blade, 21-in 532134149 if the cut is ragged or the blade is bent
• Molded ignition key 532140403 if the key is worn, cracked, or intermittently loses contact

A new engine can restore reliability and power, but it will not fix a worn deck, weak transmission, or loose steering. When the rest of the Craftsman 917271740 is healthy, an engine swap can extend the tractor’s useful life for years.

For the Craftsman riding mower model 917271740, the exact engine make and model varies by build and prior repairs, so we identify it by checking the engine ID tag on your tractor. Once you match that ID, you can confidently buy the correct tune-up and drive parts for your mower.

Look for the engine identification label, then record the key numbers.

• Lift the hood and look on the blower housing, valve cover, or near the starter
• Write down the model, type, and code (common on Briggs & Stratton)
• If it is a Kohler engine, record the model and spec numbers
• Compare the numbers to the parts diagrams for your tractor and engine
• If the label is missing, use the tractor’s deck size, frame style, and pulley/belt layout to narrow it down

Even when the engine brand differs, many wear items on a front-engine lawn tractor are deck or drive related.

• Lawn tractor ground drive belt, 1/2 x 82-in 532140294
• Molded ignition key 532140403
• Husqvarna lawn tractor mandrel assembly 532130794
• Lawn tractor blade idler spring 532169022

The engine ID is the only reliable way to get the correct engine-specific parts (carburetor, air filter, spark plug, starter). Using the tractor model alone can lead to mismatched parts if the engine was changed or produced in multiple variants.

Craftsman push mower engines are typically supplied by major small-engine manufacturers, most commonly Briggs & Stratton, with some models using Kohler or Kawasaki engines depending on the mower and year. For your Craftsman model 917271740 (a front-engine lawn tractor), engine parts and fit are best confirmed by matching the engine model and type on the tractor itself.

Look for the engine ID label, then match it to the manufacturer.

• Check the engine shroud (top cover) for a sticker or stamped tag
• Record the engine brand (for example, Briggs & Stratton, Kohler, Kawasaki)
• Write down the engine model, type, and code/spec numbers
• Use those numbers when ordering ignition, fuel, and tune-up parts
• If the label is missing, check the valve cover area or blower housing for stamped numbers

Craftsman is the equipment brand, but the engine maker controls the correct carburetor, air filter, spark plug, starter, and ignition parts. Using the engine ID prevents wrong-part returns and helps troubleshooting (no-start, hard-start, surging).

• If you need a replacement key for starting, use the molded ignition key 532140403
• For common starting symptoms (clicks, no crank, spins but will not start), follow riding lawn mower engine spins but wont start video

For a Craftsman riding lawn tractor like model 917271740, replacing the engine typically costs about $260 to $1,800 installed, depending on the engine type, labor rates, and whether related drive or deck parts also need service.

• Engine cost (new, rebuilt, or used)
• Labor time (engine swaps on riding tractors take longer than walk-behind mowers)
• Extra parts often replaced during the job (belts, pulleys, hardware)
• Shop fees and pickup/delivery (varies by area)
• Condition of the tractor (rusted fasteners, worn wiring, damaged mounts)

Even when the engine is the main issue, we often see wear in the drive and deck system that is easiest to address while everything is accessible.

• Lawn tractor ground drive belt, 1/2 x 82-in 532140294 (cracks, glazing, slipping)
• Engine pulley 532140186 (wobble, worn bore, damaged keyway)
• Molded ignition key 532140403 (worn key causing intermittent start)
• Blade drive components (idler spring, mandrel parts) if the deck was noisy or vibrating

An engine replacement only pays off if the rest of the tractor is solid. If the transmission, steering, deck mandrels, or wiring are also failing, the total repair cost can exceed the value of the mower.

• Replace the engine if the deck and transmission are in good shape and you want several more seasons.
• Repair instead if the issue is fuel, spark, or safety interlocks (many “bad engine” symptoms are not engine failures).
• Consider replacement if multiple major systems are worn and you are facing repeated repairs.
