Snapper ZT18441KHC (5900608) hydro drive ztr 350z/400z riding mower Parts

Your Snapper model number is printed on the mower’s identification tag; on many Snapper zero-turn riders it’s on the frame and is listed as the Unit Model Number (separate from the serial number). Once you find it, match that exact model number when ordering parts or looking up specifications in the ZT18441KHC owner's manual.

Where to look for the model number tag

Check these common locations on Snapper riding mowers and zero-turn mowers:

• On the frame near the operator platform or floor pan area
• On the rear portion of the frame (near the engine area)
• Under the seat area on the frame rail
• Near the mower deck area (deck model and deck serial may be listed separately)
• On a white or silver sticker or metal plate with multiple fields (model and serial)

What you should see on the tag

The identification label typically lists multiple numbers. Use the Unit Model Number for parts lookup.

Label field	What it means	What to use it for
Unit model number	The mower’s exact model identifier	Parts lookup and manual match
Unit serial number	Unique serial for your specific mower	Service history, identification
Mower deck model number	Deck-specific model	Deck parts and deck specs
Mower deck serial number	Deck-specific serial	Deck identification

Why it matters

Snapper model families can look similar but use different deck sizes, spindles, wiring harnesses, and engine components. Using the exact model number prevents ordering the wrong blade, bearing, or electrical part.

If you are ordering parts

After you confirm your model number, you can order parts from the parts list for that model, or search by model number on Sears PartsDirect. Common examples on this model page include the briggs & stratton lawn and garden equipment engine oil filter 696854 and the Snapper blade 1716696ASM.

On the Snapper ZT18441KHC zero-turn rider, the identification label that lists the model and serial information is placed on the mower frame; use the label details to match the correct parts and manual for your exact unit.

Where to look on the mower

Check these common label locations first (clean the area so the sticker or tag is readable):

• Lower right-hand side of the frame, above the right front tire
• Frame rail near the operator seat mounting area
• Inside the engine compartment area on a frame crossmember
• Near the rear of the frame by the transaxle or hydro drive components

What information to write down

Record the full set of numbers exactly as shown; this prevents ordering the wrong Snapper parts.

• Model number (for this page: ZT18441KHC)
• Manufacturing number (often shown as 5900608 on the manual cover)
• Serial number
• Engine model/type/code (engine tag is separate from the mower tag)

Quick ID checklist (why it matters)

Using the correct identification numbers helps us match the right illustrated parts breakdown and hardware sizes for your mower deck and drive system.

Item you find	Where it’s used	Why it matters
Model number (ZT18441KHC)	Mower parts lookup	Ensures correct Snapper parts diagrams
Mfg. No. (5900608)	Manual and configuration	Confirms the exact build/version
Serial number	Production run	Helps avoid fit issues across revisions
Engine code	Engine service parts	Matches engine-specific filters and tune-up parts

Use the manual to confirm the exact label location

Your ZT18441KHC owner's manual includes an “Identification Numbers” section that points you to the correct tag location and what numbers to record.

Yes. Replacement parts are still available for the Snapper ZT18441KHC rear-engine riding mower; the key is matching parts to your exact model and configuration (deck size, engine, and serial number). You can order many common maintenance and repair items directly from the parts list for this model, or search by model on Sears PartsDirect.

What to do first (so you get the right part)

• Confirm the model number is ZT18441KHC on the product ID tag.
• Use your mower’s serial number to avoid version-to-version part differences.
• Check whether you have a 44-inch or 50-inch deck, since belts and blades can differ.
• Verify the engine make/model (Kohler, Kawasaki, Briggs & Stratton) because tune-up parts vary.
• Use the exploded views and part listings in the owner's manual to cross-check what you’re replacing.

Common parts that are typically available

For this model page, we show multiple in-stock parts that cover routine service and frequent repairs, including:

• Oil filter: briggs & stratton lawn and garden equipment engine oil filter 696854
• Mower blade: Snapper blade 1716696ASM
• Electrical starting component: Snapper briggs and stratton solenoid-4 pole 12 volt dc ( 1686981YP
• Fuel system assembly: Snapper fuel tank assembly 5102544YP

Quick guide: which “type” of part you need

Need	What to look up	Typical symptom
Routine maintenance	Oil filter, blades	Hard starting, poor cut quality
Cut quality issues	Blades, deck components	Uneven cut, clumping, scalping
No-crank / click	Solenoid, wiring	Starter won’t engage
Fuel delivery problems	Fuel tank, lines, fittings	Stalling, surging, fuel smell

Why it matters

Snapper riding mower parts availability depends less on the brand name and more on exact model matching. On ZTR and hydro-drive mowers, small differences in deck setup, spindle hardware, or electrical harness routing can change the correct part.

For your Snapper ZT18441KHC, the serial number is used to identify the unit; the most dependable way to pin down the mower’s age is to record the exact model and serial numbers from the ID tag and use those numbers consistently when looking up parts and service history. The ZT18441KHC owner's manual shows where these identification numbers are recorded and referenced.

Find the right numbers first

Use the mower’s identification tag information (and the engine identification numbers) so you are working from the correct source.

• Record the unit model number (ZT18441KHC)
• Record the unit serial number exactly as printed
• Record the mower deck model number and deck serial number (if applicable)
• Record the engine make, engine model, and engine code/serial number
• Keep these numbers with your maintenance log and receipts

How to estimate age using what you have

Many riding mowers do not use a simple, universal serial-number date code. A practical way to estimate age is to combine the purchase date, engine identification date information, and your service records.

What you have	What it tells you	Best use
Date purchased (receipt)	In-service start date	Most accurate ownership age
Engine code/serial	Engine build timeframe	Confirms approximate mower timeframe
Unit serial number	Unit identity	Ensures correct parts and diagrams
Deck serial number	Deck identity	Helps if the deck was replaced

Why it matters

Getting the correct model and serial information prevents ordering the wrong parts for your Snapper mower, especially for fit-critical items like blades, bearings, and electrical components.

Parts lookup tip (when you are ready to maintain or repair)

Once you have the model and serial details written down, you can match routine service parts to the correct diagrams.

• Use the parts list for ZT18441KHC to match by diagram callout
• Common maintenance items include filters, blades, and hardware
• Example maintenance part: briggs & stratton lawn and garden equipment engine oil filter 696854
• For broader model searches and ordering, use Sears PartsDirect
