Craftsman ALL CURRENT STOCK NUMBERS mower deck Parts

For Craftsman riding mower decks, we use the model number to match the correct deck parts (blades, belts, spindles, idlers). On most Craftsman riders, you can find the model and serial tag on the frame under the seat or on the underside of the seat itself; then use that exact model number to look up parts.

Where to find the model number on a Craftsman riding mower

Check these common locations first:

• On the frame directly under the seat (lift the seat to view the sticker/plate)
• On the underside of the seat pan
• Near the rear fender area, close to the seat mounting points
• On the frame rail near the battery tray (some designs)

How to use the model number to look up the right deck parts

Once you have the tag, copy the model number exactly as printed (including dashes and suffixes). Then:

• Search using the full model number, not just “Craftsman”
• Match the product type to your machine (riding mower, tractor, or zero-turn)
• Confirm the deck size listed on the mower (common sizes are 42-inch, 46-inch, 48-inch, 50-inch, 54-inch)
• Compare your deck configuration (2-blade vs 3-blade, single belt vs double belt)

Quick checklist: what to write down

What to record	Why it matters
Model number	Drives the correct illustrated parts breakdown
Serial number	Helps confirm production run changes
Deck size (inches)	Narrows blade and belt fit
Number of blades	Confirms spindle and belt routing

Why it matters

Craftsman deck parts change across stock numbers and production runs; using the exact model number prevents ordering the wrong mower deck belt, blade set, or mandrel (spindle) assembly.

Craftsman serial numbers are read by matching the format on your ID label. Many Craftsman riding mowers and mower decks use a 6-digit date code (MMDDYY), but other units use longer numeric or alphanumeric serials that do not decode as a simple date.

Step 1: Find the ID label and copy everything

For Craftsman mower decks, the ID label or stamped tag is usually on the deck shell or tractor frame. Record the model number and the full serial number exactly as shown.

• Top of the mower deck near the belt cover or spindle area
• Deck hanger bracket area (front or side)
• Frame rail near the engine or under the seat (riding mowers)
• Inside a fender well
• Near the rear frame or hitch plate

Step 2: Identify which serial format you have

Use the serial number length and characters to decide how to read it.

What you see on the label	Common meaning	How to read it
6 digits, ALL numbers (example: 072811)	Date-style code	MM DD YY (month, day, year)
Longer number string (8 to 12+ digits)	Production sequence code	Use the full serial for identification; it is not a direct date
Letters + numbers mixed	Factory/production code	Use the full serial for identification; it is not a direct date

If your serial is a 6-digit date code (MMDDYY)

Read it like this:

• First 2 digits: month (01 to 12)
• Next 2 digits: day (01 to 31)
• Last 2 digits: year (00 to 99)

Example: 072811 = July 28, 2011.

Why it matters for mower deck parts

Craftsman can change deck designs within the same product family. Using the full model and serial helps match the correct blades, belt, spindles, idler pulleys, and hardware.

Tips to avoid ordering the wrong parts

• Clean the label so every character is readable
• Write down the full model and serial; do not drop leading zeros
• Confirm deck size (42-inch, 46-inch, 54-inch) before buying parts
• Compare mounting holes and pulley/blade interfaces on the old part
• Use how to find your appliance model number (and what it means for parts) to confirm the right identification numbers

Common Craftsman lawn mower problems include no-start or hard-start, stalling/surging, loss of power, uneven cutting, and excessive deck vibration. Because this page covers many Craftsman mower deck stock numbers (not a single model), these are the most frequent issues we see across Craftsman walk-behind and riding mowers.

Most common symptoms and what they usually point to

• Won’t start / starts then dies: stale fuel, clogged carburetor, dirty air filter, fouled spark plug, or a safety interlock (riding mowers)
• Runs rough / surges: partially restricted carburetor, vacuum leak, dirty fuel, or choke not opening fully
• Loses power under load: clogged deck, dull blades, restricted cooling fins/shroud, or fuel delivery restriction
• Cuts unevenly / scalps: deck out of level, bent/dull blade, worn spindle bearings, or low tire pressure (riding mower)
• Vibration or rattling: bent blade, debris wrapped around a spindle, loose blade hardware, or damaged pulley

Quick checks we recommend first

1. Replace old gas with fresh fuel; use the correct octane and stabilizer for storage.
2. Clean or replace the air filter; clear grass from the engine cooling area.
3. Inspect and replace the spark plug if fouled; set the correct gap.
4. Clean packed grass from under the mower deck; check blades for bends and nicks.
5. On riding mowers, verify the seat switch, brake switch, and PTO switch operation.

Deck-related issues that mimic engine problems

A dragging deck can make the engine bog, surge, or stall.

Symptom	Likely deck cause	What to inspect
Engine bogs in thick grass	Buildup or dull blades	Deck underside, blade sharpness
Squeal or burning smell	Belt slip or idler issue	Belt wear, idler pulley spin/tension
Loud grinding	Spindle bearing wear	Spindle play, pulley alignment
Uneven cut	Deck not level	Deck height settings, tire pressure

Why it matters

Fixing the root cause prevents repeat failures; for example, a bent blade can quickly damage spindles and belts, and old fuel can clog the carburetor and foul a new spark plug.

Craftsman model ALL is not a single production model year range; it is a catch-ALL label used to group “ALL current stock numbers” for Craftsman mower deck parts. To get the exact years made, we match the actual tractor or deck model number from your ID tag to its production range.

How to identify the correct years for your Craftsman mower deck

Use the model and product number from the equipment label, then cross-reference it to the correct parts listing.

• Look for an ID tag under the seat, on the frame rail, or near the engine
• Write down the model number and any product number (often a 917.xxxxx format on many Craftsman tractors)
• If the deck has its own tag, record the deck model and deck size (for example, 42 in, 46 in, 48 in)
• Note the engine brand (Briggs & Stratton, Kohler) and transmission type (gear, hydro) to avoid mismatches
• Use the model number to confirm the correct deck parts such as blades, mandrel/spindle assemblies, idler pulleys, belt keepers, and deck belt

Example of how “years made” is typically shown

When a Craftsman tractor is identified by its real model, the production range is usually listed in a format like the example below.

What you have	What you need to find	What you can then determine
“Craftsman ALL” deck parts grouping	Your exact tractor or deck model number	The correct parts diagrams and typical production years
LT-series name (example: LT1000)	The full model identifier from the ID tag	The specific year range for that exact variant

Why it matters

Craftsman mower decks changed frequently across years (belt routing, spindle height, pulley diameter, and blade center hole patterns). Matching by the exact model number prevents ordering the wrong deck belt, blades, or spindle parts.
