Craftsman 917273320 tractor Parts

For Craftsman lawn tractor model 917273320, the most reliable way to tell the year is to match the manufacture date code on the tractor (typically on the product ID tag) to the date-code format shown in the 917273320 owner's manual. That tag date is the build date for your specific tractor.

Where to find the date information

Look for a product identification tag or decal on the tractor. Common locations include:

• Under the seat pan (lift the seat)
• On the frame rail near the engine
• Near the rear fender area
• Under the hood near the dash tower
• Near the transaxle area on the frame

How to decode it (what to look for)

Most riding mower tags include a serial number and sometimes a date code. When you find the code:

• Write it down exactly (letters and numbers)
• Look for a pattern that separates month, day, and year
• Compare it to the identification information and examples in the manual
• Use the decoded date as the tractor’s “year” for maintenance history and parts matching

Quick example of a common date-code pattern

Some tags use a format where the code includes:

Code segment	Often represents	Example meaning
First 2 digits	Month	07 = July
Next 2 digits	Day	12 = 12th
Last 2 digits	Year	94 = 1994

(Your tractor’s tag may use a different pattern, so always confirm with the manual and the exact tag on your unit.)

Why it matters

Knowing the build year helps us match the correct parts and specs for your Craftsman tractor, especially for items that change over production runs (belts, electrical parts, and deck hardware). If you are troubleshooting an electrical no-start, the wiring diagrams in the manual are also key.

On the Craftsman riding tractor model 917273320, the engine identification is on the engine itself, not on the mower deck or hood. Your manual lists the engine as a Kohler CV26S with type number 69526; use that ID when ordering engine-specific parts and tune-up items. See the 917273320 owner's manual for the engine breakdown and labeling references.

Where to look on the engine

Check these common ID locations on Kohler V-twin engines used on riding lawn tractors:

• On the blower housing or shroud near the recoil or cooling air intake area
• On the valve cover area or near the cylinder head
• On a label or stamped pad near the starter or flywheel side
• Near the carburetor/intake side of the engine
• On a metal tag or sticker attached to the engine shroud

What numbers to write down

For the best match, record all identifiers you see (even if one is partially worn).

What to record	Example for this tractor	Why it matters
Engine model	CV26S	Identifies the engine family
Type number	69526	Narrows down the exact build/spec
Spec/serial (if shown)	Varies	Helps match carb, ignition, and gasket variations

Quick tips to avoid ordering the wrong part

• Clean the area first; oil and grass dust can hide the stamp or label.
• Copy the characters exactly; letters and numbers can look similar.
• Use the engine model and type when shopping for engine parts; use the tractor model 917273320 for chassis, deck, steering, and drive parts.
• If you are replacing the ignition key, match it to the tractor model; the molded ignition key 532140403 is a common tractor-side part.

Why it matters

The tractor model number identifies the frame, mower deck, belts, and controls, but the engine model and type number identify the correct Kohler ignition, fuel, and internal engine parts. Using both prevents fit and wiring mismatches.

For a Craftsman riding mower like model 917273320, we look up the model number on the product ID label, which is typically on the frame under the seat or on the underside of the seat. Once you have the full model number, you can match the correct parts and specifications in the 917273320 owner's manual.

Where to find the model number on a Craftsman riding mower

Check these common label locations first:

• On the frame directly under the seat (lift the seat to view)
• 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 (on some builds)

What to write down (so parts match correctly)

Record the information exactly as shown on the label.

• Model number (for this tractor: 917273320, sometimes printed with a dot as 917.273320)
• Serial number (helps confirm production run)
• Any engine model/type/code listed on the engine tag (useful for tune-up parts)

Label item	What it’s used for	Example you may see
Model number	Main identifier for tractor parts diagrams	917273320 (or 917.273320)
Serial number	Confirms exact build version	Varies
Engine ID	Matches engine-specific parts	Varies

Why it matters

Using the exact model number prevents ordering the wrong belt, blade, PTO switch, or steering parts. Even small differences in a Craftsman tractor series can change deck size, drive system parts, and hardware.

For Craftsman model 917273320, the 54-inch mower deck belt length depends on the exact deck and belt routing; the most reliable way to confirm the correct belt specification is to match the deck belt by model and deck configuration in the 917273320 owner's manual.

How to identify the correct 54-inch deck belt

We recommend confirming these details before ordering a replacement belt:

• Verify the mower deck size and style (54-inch decks can use different belt paths)
• Check whether your deck uses one belt or multiple belts
• Compare the belt routing diagram to your deck’s idler pulleys and mandrel pulleys
• Inspect the old belt for any printed size or part number (often worn off)
• Confirm whether the belt rides on a flat idler or a V-idler in key locations

Quick belt measurement guidance (if the old belt is available)

If you still have the old belt, measuring it helps you validate you are buying the right replacement.

• Measure the belt’s outside circumference with a flexible tape
• If the belt is broken, wrap a string around the full path and measure the string
• Note belt profile (V-belt vs. flat) and approximate top width

Typical deck belt sizing (what to expect)

Deck size	Common belt type	Typical belt length range
54-inch riding mower deck	V-belt	About 140 to 150 inches

Related parts that affect belt fit and performance

A belt that slips, squeals, or jumps off is often caused by worn pulleys or tension hardware, not just belt stretch.

• Lawn tractor idler pulley 532139245 (worn bearing can cause squeal and heat)
• Lawn tractor mandrel pulley 532173436 (groove wear can throw the belt)
• Check idler arm movement and spring tension (binding changes belt tracking)

Why it matters

Using the correct deck belt length and profile keeps blade speed consistent, prevents premature belt wear, and reduces the chance of the belt coming off during engagement.

Yes, replacing the engine on your Craftsman 917273320 front-engine lawn tractor is worth it when the tractor’s deck, steering, and transmission are solid and the total engine-swap cost stays well below the price of a comparable new riding mower. If multiple major systems are worn, replacement makes more sense.

Quick decision checklist

• The mower deck is not rusted through and still cuts evenly after leveling
• The transmission drives smoothly (no slipping, no loss of drive)
• The frame and steering are tight (no excessive play or bent linkage)
• You can source the correct engine and mounting hardware for this tractor
• The repair cost is clearly less than buying a new unit (a common cutoff is about 50%)
• You plan to keep the tractor several more seasons

Cost and value comparison

Option	Upfront cost	Reliability after repair	Best when
Replace engine	Medium to high	High if the rest of the tractor is sound	Deck and drivetrain are in good shape
Repair existing engine	Low to medium	Medium	Issue is fuel, spark, or maintenance related
Replace tractor	High	High	Deck, transmission, and steering show heavy wear

Before you commit: rule out common “engine is bad” problems

Many no-start or low-power complaints are maintenance related. Our manual calls out routine items like air filter care, spark plug replacement intervals, fuel filter replacement, and oil checks. Use the 917273320 owner’s manual to confirm the correct tune-up schedule and specs.

Start with these checks:

• Fresh gasoline; drain stale fuel if it sat over a season
• Clean or replace the air filter (a clogged filter causes loss of power)
• Replace the spark plug if it is fouled or past the service interval
• Replace a clogged fuel filter if fuel flow is restricted
• Verify safety interlocks and wiring are intact (seat switch, PTO switch)

If the engine clicks or cranks but will not start, follow riding lawn mower engine spins but wont start video for a step-by-step diagnosis.

Why it matters

An engine swap can restore dependable starting and power, but it does not fix worn deck components, a slipping drive system, or safety switch problems. Confirming the tractor’s overall condition prevents spending engine money on a mower that still will not perform.
