Husqvarna 917384511 lawn mower Parts

Yes. For Husqvarna lawn mower model 917384511, SAE 30 is the correct engine oil choice for warm-weather mowing (above 32°F). When temperatures drop below 32°F, SAE 10W-30 is the better option for easier starting and lubrication; see the owner's manual for the exact oil guidance.

Recommended oil type and when to use it

Use a high-quality detergent oil with an API service rating in the SJ to SL range.

• SAE 30: best for above 32°F
• SAE 10W-30: best for below 32°F
• Check oil level before starting and after every 5 hours of continuous use
• Change oil every 25 hours of operation or at least once per year

Quick reference table

Outdoor temperature	Oil to use	Why it helps
Above 32°F	SAE 30	Maintains proper viscosity in warm conditions
Below 32°F	SAE 10W-30	Flows better for cold starts

Tips to avoid oil-related engine problems

• Park the mower on a level surface before checking the dipstick
• Do not overfill; too much oil can cause smoking and rough running
• Tighten the oil fill plug securely after checking or adding oil
• If you need to tip the mower to drain oil, run the engine until the fuel tank is empty first (per the manual)

Why it matters

Using the right viscosity oil helps protect the crankshaft and internal engine parts, improves starting in cold weather, and reduces wear during hot-weather mowing.

For your Husqvarna lawn mower model 917384511, use regular unleaded gasoline with a minimum of 87 octane. Using 89 octane will not improve performance in normal mowing; the bigger priority is using fresh fuel and avoiding higher-ethanol blends.

What we recommend for fuel

Use these fuel guidelines to help your mower start easier and run more consistently:

• Use fresh, clean, regular unleaded gas (at least 87 octane)
• Avoid gasoline with more than 10% ethanol (E10)
• Buy only what you can use in about 30 days to keep fuel fresh
• Do not mix oil with gasoline (this is a 4-cycle engine setup)
• Wipe up spills and keep fuel away from ignition sources

For the exact fuel notes and capacity listed for this model, check the owner's manual.

87 vs 89: what changes and what does not

In most walk-behind mower engines, higher octane does not add power; it mainly resists knock in engines designed for it.

Fuel choice	Works in model 917384511?	When it makes sense
87 octane (regular)	Yes (recommended minimum)	Everyday mowing and normal temperatures
89 octane (mid-grade)	Yes	Only if 87 is unavailable or you prefer it; no typical performance gain

Ethanol and storage tips (prevents hard starting)

Ethanol-blended fuel can absorb moisture during storage, which can lead to rough running or starting problems. If the mower will sit for 30 days or longer:

• Run the tank low and empty the fuel system before storage
• Start the engine and let it run until it stops (fuel lines and carburetor run dry)
• Refill with fresh fuel when you put it back in service

Why it matters

Using the correct octane (87 minimum) and keeping fuel fresh helps protect the carburetor and fuel system, reduces varnish buildup, and prevents common “won’t start” complaints after storage.

Husqvarna model 917384511 uses many different part numbers because each assembly (blade system, wheels, deck, controls, and engine hardware) has its own replaceable components. The fastest way to identify the correct part number is to match your mower’s diagram callout to the parts list in the 917384511 owner's manual.

What “part number” can mean on this mower

You may see more than one identifier for the same item:

• Part name: what the item does (example: lawn mower blade)
• Part ID: the Sears PartsDirect identifier used to order (example: 532406712)
• Manufacturer part number: the number stamped on packaging or in diagrams (example: 406712)
• Assembly location: where it appears (deck, chassis, handle, engine, etc.)

Common 917384511 parts (examples you can order)

These are real examples of parts listed for Husqvarna 917384511 on this model page:

• Lawn mower blade 532406712
• Lawn mower blade adapter 532418373
• Clipping deflector 589482402
• Lawn mower wheel 585911001
• Lawn mower zone control cable 532183281
• Rear door assembly 532401814

Quick reference table

What you’re replacing	Part name (example)	Part ID (ordering)
Cutting blade	Lawn mower blade	532406712
Blade mounting hub	Lawn mower blade adapter	532418373
Side discharge flap	Clipping deflector	589482402
Drive/roll component	Lawn mower wheel	585911001
Operator control	Lawn mower zone control cable	532183281

How we recommend finding the exact part number you need

Use this process so you do not order the wrong version:

• Find your model number: 917384511 on the mower label.
• Identify the system: deck, handle/controls, wheels, or engine.
• Use the diagram callout and description in the parts list (the manual helps confirm names).
• Compare your old part to the listing (shape, mounting holes, and orientation).
• If you’re replacing a blade, follow safe removal steps from lawn mower blade removal tool.

Why it matters

Walk-behind mowers often have multiple “close” versions of blades, wheels, and control cables. Matching the diagram callout and part ID prevents fit issues, vibration, poor cutting, or control problems.
