About This Craftsman Lawn Mower
This riding lawn tractor is part of Craftsman’s YT4000 series, built by Husqvarna during a period when Craftsman outsourced much of its riding equipment manufacturing to Husqvarna rather than building tractors in house. Closely related YT4000 siblings from the same production years used either a Briggs and Stratton or a Kohler V-twin engine depending on the exact model number, so confirming the engine badge under the hood matters when ordering a carburetor or ignition coil rather than assuming based on the tractor’s YT4000 family name alone. The tractor uses a Tuff Torq hydrostatic transaxle, a sealed drive unit that eliminates the shifting gears found on older manual transmission tractors, which changes the diagnostic approach for a tractor that will not move under power compared to troubleshooting a belt driven gear transmission. A high back seat with sliding adjustment and an open operator station round out the platform’s comfort features across the YT4000 lineup. Seasonal habits like sharpening the blade, checking tire pressure on wheeled models, and clearing grass buildup from the underside of the deck all add up to fewer mid season breakdowns and a cleaner, more even cut over the life of the machine. Keeping the underside of the deck free of packed grass clippings also helps the mower discharge or mulch properly, since a caked deck restricts airflow and can leave visible clumps behind on an otherwise well maintained lawn. A quick visual check of the wheel height adjusters, handle hardware, and safety controls at the start of each season catches small issues, like a loose bolt or a sticking cable, before they turn into a bigger repair mid mow. Draining or stabilizing leftover fuel before the mower sits unused for more than a month or two remains one of the simplest ways to avoid a hard starting complaint the following season. Mowing at a slightly higher deck setting during hot, dry stretches puts less strain on the engine and blade than scalping the lawn short, and it tends to leave the grass healthier once cooler weather returns. Cleaning debris out from around the muffler and cylinder cooling fins periodically helps the engine run at a safer operating temperature, particularly during long mowing sessions on a hot afternoon. Rotating or replacing the blade before it becomes visibly dull, rather than waiting for grass to look torn instead of cleanly cut, reduces the extra strain a dull blade places on the engine and drive system. Keeping the owner’s manual on hand, whether in print or as a downloaded PDF, makes it easier to look up the correct oil type, blade torque, and maintenance interval specific to this mower rather than relying on general assumptions.

Most Replaced Parts on the 917.288570
Carburetor and Hard Starting Issues on the 917.288570
A V-twin engine that cranks slowly, floods, or stumbles at idle after sitting over winter usually has a gummed up carburetor from stale, ethanol blended fuel. Confirm the fuel is fresh and the air filter is clean before disassembling the carburetor.
Spark Plug and Ignition Coil Problems on the 917.288570
This V-twin engine uses two spark plugs, one per cylinder, so uneven running or a miss under load often traces back to just one fouled plug rather than both. Test and replace plugs before condemning either ignition coil, since fouled plugs are considerably more common than a failed coil.
Hydrostatic Drive and No Movement Problems on the 917.288570
If the tractor starts and the engine runs normally but the tractor will not move, check the drive belt connecting the engine to the Tuff Torq transaxle before assuming the transaxle itself has failed internally. A slipped or broken belt is a far more common and less costly repair than a sealed transaxle problem.
Safety Switch and No Start Problems on the 917.288570
This tractor will not start unless the seat switch, brake safety switch, and blade engagement switch all report the correct position to the control system. Before assuming the starter or solenoid has failed, confirm the operator is seated, the brake is fully depressed, and the blades are disengaged.

917.288570 Parts FAQ
What engine and transmission does this tractor have?
It uses a V-twin engine, either Briggs and Stratton or Kohler depending on the exact model, paired with a Tuff Torq hydrostatic transaxle for smooth, gearless drive.
Why won’t the tractor move even though the engine runs?
Check the drive belt connecting the engine to the transaxle first, since a slipped or broken belt is far more common than an internal transaxle failure.
Why won’t the tractor start even though the key turns?
Check the seat switch, brake safety switch, and blade engagement switch first, since the engine will not crank unless all three report the correct position.
Why is the tractor running rough on only one cylinder?
A single fouled spark plug is a common cause on this V-twin engine. Test and replace both plugs individually before assuming an ignition coil has failed.
