Craftsman 917273135 tractor Parts

Craftsman model 917273135 was produced during the LT1000-era of Craftsman front-engine lawn tractors, which is typically late 1990s through mid-2000s. For the exact build year of your specific tractor, use the identification and documentation details in the 917273135 owner's manual.

How to pinpoint the exact year for your tractor

Use these quick checks; they work even when the model family spans multiple years:

• Look for the product identification label (commonly under the seat or on the frame near the rear fender pan).
• Record the serial number exactly as shown.
• Compare the tractor’s configuration to the illustrated parts lists in the manual (chassis, steering, seat, decals).
• Match major assemblies that often changed over time (deck style, hood/dash layout, wiring harness routing).
• If you are replacing wear items, confirm the part by model before ordering (blade, belt, mandrel).

What the manual confirms for this model

The documentation we have is explicitly labeled for TRACTOR, MODEL NUMBER 917.273135 and includes detailed parts breakdowns (for example: chassis and enclosures, steering assembly, seat assembly, decals, and lift assembly). That confirms you are working from the correct model family documentation when you cross-check your tractor’s ID tag and configuration.

Common “year” clues vs what they mean

What you find	What it usually tells you	What to do next
Model number 917273135	Identifies the model family/configuration	Use serial number to narrow the build year
Serial number on frame/under seat	Best indicator of production run	Use it with the manual’s identification section
Deck/blade type	Helps confirm deck size and setup	Verify blade and belt match your deck

Why it matters

The exact year affects parts compatibility for items like the mower deck, drive system, and electrical/safety interlocks. Confirming the build year and configuration helps you avoid ordering the wrong blade, V-belt, or mandrel components.

For the Craftsman lawn tractor model 917273135, we use a high-quality detergent 4-cycle engine oil that meets API service classification SF-SJ, and we choose the SAE viscosity based on the outdoor temperature (the manual includes an oil viscosity chart). See the 917273135 owner's manual for the exact viscosity recommendation for your season.

Recommended oil type and viscosity

Use oil that matches these requirements:

• 4-cycle (4-stroke) engine oil (not 2-cycle mix)
• High-quality detergent oil
• API rating: SF through SJ
• SAE viscosity: pick based on expected operating temperature (warm weather vs. cold weather)

If you mow in colder weather, switching to a lighter winter-grade oil helps with easier starting (as shown in the manual’s viscosity chart).

Quick oil-check and change basics (model 917273135)

The owner’s manual for this tractor calls out these best practices:

• Check oil with the tractor on level ground
• Wipe the dipstick, reinsert it, then read the level
• Fill only to the FULL mark; do not overfill
• Check oil before starting and about every 8 hours of operation
• Change oil every 50 hours of operation or at least once a year

Oil selection guide (simple)

Your mowing conditions	What to do	Why
Typical spring and summer mowing	Use the manual’s warm-weather viscosity	Protects the engine at higher temps
Late fall or cold-weather use	Use the manual’s cold-weather viscosity	Improves starting and lubrication
Tractor sits for long periods	Change oil at least annually	Removes moisture and contaminants

Why it matters

Using the correct API-rated oil and the right viscosity helps your 17.0 HP engine stay lubricated, run cooler, and resist wear. It also reduces hard-start complaints that often show up when oil is too thick for the temperature.

For the Craftsman 917273135 front-engine lawn tractor, the essential parts are the systems that make it start, move, stop, and cut safely: engine and fuel delivery, drive and steering, electrical and safety interlocks, and the mower deck (blades, belts, and spindles). See the 917273135 owner's manual for your control locations and safety steps.

Essential systems to keep in good shape

These are the parts and assemblies that most directly affect reliability and cut quality:

• Engine and fuel system: fuel tank, fuel line/filter, carburetor, spark plug, air filter, engine oil
• Electrical and starting: battery, ignition switch/key, starter/solenoid, wiring connections
• Drive and braking: transaxle/transmission, ground drive belt, clutch/brake pedal linkage, parking brake
• Steering and front axle: steering wheel/shaft, tie rods, axle bearings/bushings
• Mower deck and blade drive: deck belt, idler pulleys/springs, mandrel (spindle) assemblies, blades
• Tires and wheels: tires, rims, valve stems, tire pressure

Model-specific examples of “essential” wear parts

These are common maintenance or failure items we see on 42-inch deck tractors like model 917273135.

System	What it does	Example part for this model
Blade drive	Transfers power to spin blades	V-belt 532138255
Cutting	Cuts grass; affects cut quality	Lawn tractor 42-in deck high-lift blade 532138971
Spindle/mandrel	Supports blade and pulley; reduces vibration	Husqvarna lawn tractor mandrel assembly 532130794
Starting/security	Lets you start the tractor	Molded ignition key 532140403

Quick checks we recommend before each mow

Your manual calls out several basics that prevent no-starts, poor cutting, and premature belt wear:

• Check engine oil level and add oil if needed
• Use fresh regular unleaded gasoline
• Confirm tires are properly inflated (important for deck leveling)
• Verify the mower deck is level side-to-side and front-to-rear
• Inspect mower and drive belts for cracking, glazing, or misrouting
• Look over wiring connections to make sure they are secure and clamped

Why it matters

Most “tractor problems” trace back to a few essentials: low battery or loose wiring (no crank), stale fuel (won’t start), worn belts or mandrel bearings (poor cut and vibration), or out-of-adjustment brakes (unsafe operation). Keeping these core parts maintained saves time and protects the transaxle and deck.

For the Craftsman tractor model 917273135, the engine parts are grouped by system so you can identify what you need quickly: fuel delivery, starting, lubrication, exhaust, and internal engine components such as the cylinder head, valves, and crankshaft. Use the 917273135 owner's manual to match the exact diagram and key number.

Major tractor engine systems (what you will see in parts diagrams)

These are the main assemblies typically listed for a front-engine riding lawn tractor engine:

• Fuel system: fuel tank, cap, fuel line, hose clamps, carburetor, air cleaner gaskets
• Starting system: starter assembly and starter drive components
• Lubrication: dipstick assembly, oil fill cap, O-rings, drain tube or drain plug parts
• Exhaust: muffler, exhaust manifold gasket, spark arrester (if equipped)
• Cylinder head and valve train: cylinder head, intake and exhaust valves, push rods, rocker arms, valve springs, breather parts
• Crankshaft and rotating parts: crankshaft and related fasteners

Examples of engine-related parts called out for model 917273135

The manual’s engine breakdown for this model commonly lists items like these:

System	Example parts you may see listed	What it affects
Fuel	Fuel tank, cap, fuel line, clamps	Starting, stalling, fuel leaks
Starting	Starter assembly	Cranking and turn-over
Lubrication	Dipstick assembly, oil fill cap, O-rings	Oil level control, oil leaks
Exhaust	Muffler, exhaust gasket, spark arrester	Noise, power, exhaust leaks

Quick tips for identifying the right engine part

• Match the model number 917273135 first; then use the engine diagram key numbers.
• Identify the system first (fuel, starting, lubrication, exhaust) before choosing a part.
• Replace sealing items (gaskets, O-rings) whenever you open a sealed joint.
• If you are also troubleshooting poor cutting or heavy load, inspect the deck drive components; a worn blade can increase load. A common example is the lawn tractor 42-in deck high-lift blade 532138971.

Why it matters

Engine symptoms overlap. A “won’t start” issue can be fuel delivery, starter cranking, or oil-related safety conditions; using the correct system diagram prevents ordering the wrong part.
