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.

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)

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)

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.

If the tag is missing or unreadable, use our guide: how to find your appliance model number (and what it means for parts).

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.

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

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

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.

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.

• 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.

• 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

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.

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

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.

Use how to find your appliance model number (and what it means for parts) to identify your Craftsman stock number so you can match the correct deck parts (blades, belts, spindles, idlers) to your mower.

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.

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

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

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.
