Craftsman 917276780 tractor Parts

The Craftsman lawn tractor model 917276780 holds 56 oz of engine oil with the oil filter and 48 oz without the filter. Use the dipstick to set the final level at the FULL mark after filling, since draining and filter changes can vary slightly.

Your 917276780 uses common small-engine oil weights based on temperature (check the chart in the 917276780 owner's manual).

• SAE 30 for temperatures above 32°F
• SAE 5W-30 for temperatures below 32°F
• Use an oil that meets API SG through SL

• Park on a level surface and let the engine cool.
• Remove the oil fill cap/dipstick, wipe it clean.
• Add oil slowly toward the correct capacity (48 oz or 56 oz).
• Reinsert and tighten the dipstick, wait a few seconds, then recheck.
• Stop when the oil reaches the FULL mark; do not overfill.

Correct oil capacity helps protect the engine from overheating and premature wear. Too little oil can starve internal parts; too much oil can cause foaming, smoking, and poor running.

To look up the model number for your Craftsman riding mower, find the model and serial number label on the tractor frame under the seat (or on the underside of the seat). For model 917276780, the model number is also shown on the cover of the 917276780 owner's manual.

On most Craftsman front-engine lawn tractors, the ID label is in one of these common spots:

• On the frame directly under the seat
• On the underside of the seat pan (flip the seat up)
• Near the rear fender area close to the seat mounting points
• Occasionally on the frame rail near the engine compartment

Use the full model number exactly as printed (including all digits) to match the correct parts diagrams and maintenance information.

• Enter the model number when searching for parts like blades, belts, and ignition keys
• Use it to confirm deck size and engine specs before ordering
• Match it to the correct operator instructions and maintenance schedule
• Keep it handy for service calls and troubleshooting

Craftsman tractors often share similar looks across multiple model numbers, but parts like the ground drive belt, mower blades, and starter solenoid can vary by model. Using the correct model number helps ensure the part fits and the repair steps match your tractor.

The Craftsman lawn tractor model 917276780 uses a 20.0 HP, 42-inch mower configuration per the operator documentation; that manual does not identify an “IntelliPOWER” 547cc engine maker for this model. For the correct engine manufacturer, match the engine’s model and type code on the engine label to the listings in the 917276780 owner's manual.

Use the engine’s ID tag, not the tractor model number. On most front-engine riding mowers, the engine label is on the blower housing, valve cover, or near the starter.

• Turn the key off and remove it; let the engine cool completely
• Lift the hood and locate the engine ID label or stamped plate
• Write down the engine model, type, and code (or spec number)
• Compare those numbers to the engine maker’s lookup (Briggs and Stratton, Kohler, Tecumseh, etc.)
• Use the engine ID when ordering tune-up parts (air filter, spark plug, fuel filter)

“IntelliPOWER” is commonly used as a technology name on some riding mower lines, but the 917276780 documentation we have focuses on operation, safety, and maintenance and does not call out that branding.

The engine maker determines the correct carburetor parts, ignition parts, and service specs. Using the engine model/type/code prevents ordering the wrong parts even when two tractors share the same 42-inch deck size.

For the Craftsman riding lawn tractor model 917276780, we use 4-cycle engine oil; SAE 5W-30 is a solid all-temperature choice for most mowing conditions. Always confirm the exact oil type and oil-change interval in the 917276780 owner's manual.

Most Craftsman front-engine lawn tractors use a standard 4-stroke (4-cycle) engine that takes detergent motor oil.

• Use 4-cycle engine oil (not 2-cycle mix)
• SAE 5W-30 works well for a wide range of temperatures
• If you mow in consistently hot weather, SAE 10W-30 is also commonly used on riding mowers
• Check oil level before each use; low oil can cause loss of power and engine damage
• Change oil more often under heavy load or high ambient temperatures (as noted in the maintenance schedule)

Correct engine oil keeps internal parts lubricated and helps control heat. The manual’s maintenance schedule also ties oil checks and oil changes to reliable starting, steady power, and longer engine life.

• Park on level ground before checking oil
• Clean grass and debris off the engine area to reduce heat buildup
• Keep fasteners tight and inspect belts and blades on schedule
• If you notice power loss, check oil level and condition as part of troubleshooting

For a Craftsman riding mower like model 917276780, the most reliable way to identify the year is to read the product identification tag (model and serial number) and then decode the serial number date code using the format shown in your 917276780 owner's manual.

On most Craftsman front-engine lawn tractors, the ID tag is typically in one of these spots:

• Under the seat pan or on the seat support
• On the rear fender area near the seat
• On the frame rail near the engine compartment
• Near the transmission area on the frame

Write down both the model number (917276780) and the serial number exactly as shown.

Many Craftsman tractors use a 6-digit date code at the start of the serial number:

• MM = month
• DD = day
• YY = year

Example:

If your serial number begins with letters or uses a different pattern, use the identification and specifications sections in the 917276780 owner's manual to confirm the correct tag format for your tractor.

Knowing the build year helps us match the correct Craftsman parts and service procedures, especially for items that change over production runs (mower deck blades, belts, mandrel assemblies, and electrical parts).

When ordering or troubleshooting, these are the most year-sensitive items:

• Mower deck blades (mulching vs. high-lift)
• Ground drive belt routing and length
• Mandrel and spindle components
• Starter and solenoid wiring style
• Steering and brake linkage revisions

If you are replacing deck components, match your setup to the correct blade type, such as the husqvarna lawn tractor mulching blade, 21-in 532134149 or the lawn tractor 42-in deck high-lift blade 532138971.

The Craftsman lawn tractor model 917276780 is equipped with a 20.0 HP gasoline engine with electric start (paired with an automatic transmission and a 42-inch mower deck). For the exact engine manufacturer and engine model code on your tractor, match the ID tag on the engine and the specifications in the 917276780 owner's manual.

The tractor model number identifies the chassis and deck; the engine has its own ID label that you use for engine parts and service.

• Look for an engine ID decal or metal tag on the blower housing
• Check near the valve cover or spark plug area
• Inspect around the muffler heat shield area (let the engine cool first)
• Wipe off dirt and oil so the numbers are readable
• Write down every line exactly as shown

Engine parts (air filter, spark plug, carburetor, starter components) are selected by the engine’s brand and model code, not just the tractor model number. Deck and drive parts are selected by the tractor model.

These are common tractor-side parts for the 42-inch cutting system and drive; match by your deck setup and symptoms.

• Blades (mulching vs. high-lift)
• Mandrel and mandrel pulley components
• Ground drive belt
• Starter solenoid (starting issues)

If you’re refreshing the cutting system, common blade options include the husqvarna lawn tractor mulching blade, 21-in 532134149 and the lawn tractor 42-in deck high-lift blade 532138971.
