MTD 31A-240-752 snow thrower Parts

To tell the year of your MTD snow thrower model 31A-240-752, we use the model and serial number label on the unit; the serial number format is what lets you decode the build date. The most reliable method is to match your serial number to the date-code format shown in the owner's manual.

Where to find the serial number

On this MTD snowblower, the model/serial label is on the frame (commonly near the rear of the unit when you’re standing in the operator position and looking down). Write down both numbers exactly as shown.

• Look for a sticker or metal tag labeled MODEL NUMBER and SERIAL NUMBER
• Clean off snow, salt, and grime so every character is readable
• Copy the serial number carefully (letters and numbers)
• Take a photo before the label wears further
• Keep the number with your maintenance records for parts lookup

How the “year” is typically encoded (what to check)

MTD has used more than one serial-number date format over the years. Once you have the serial number, compare it to the date-code examples in the manual and decode it from left to right.

What you see on the label	What it usually means	What to do next
Serial number includes a clear date pattern	Exact build date is embedded	Decode the date characters using the manual’s format notes
Serial number does not look like a date	Year may be encoded by position	Use the manual’s serial-number guidance, then confirm by parts list match
Label is missing or unreadable	Year cannot be decoded from the unit tag	Use engine tag info and compare to the parts diagrams for 31A-240-752

Why it matters

Knowing the build year helps us match the correct auger, chute, belts, and hardware for your exact configuration. Even within the same model family, MTD can change pulleys, cables, and fasteners across production runs.

Tip: use the year to confirm common wear parts

If you’re already checking age because performance changed, these are common wear items to inspect on a snowblower:

• Drive and auger belts (cracking, glazing, stretching)
• Cables and springs (binding, slack, broken ends)
• Scraper blade and skid shoes (uneven wear)
• Chute components (stiff rotation, weak return)

For belt-related issues, the snowblower ground drive belt 754-0367 is one of the listed parts for this model.

On the MTD snow thrower model 31A-240-752, the model number is on the model plate; stand in the operator’s position and look down at the rear of the deck to find it. Record both the model and serial number for parts lookup and service.

Where to look on your snowblower

Check these common model plate locations first:

• Rear of the deck (look down from the operator’s position)
• Rear frame area between the wheels
• Side of the auger housing
• Near the engine mounting area
• On the engine itself (engine model and type are separate from the snowblower model)

What to write down (and why)

You typically need both identifiers:

Item to record	What it’s used for	Example format
Model number	Matches the correct parts diagrams and part numbers	31A-240-752
Serial number	Helps narrow production variations and correct revisions	Varies by unit

Tips to make the label easier to read

If the sticker is dirty or faded, these steps usually help:

• Brush off packed snow, salt, and debris
• Wipe the plate with a damp rag, then dry it
• Use a flashlight at an angle to highlight stamped numbers
• Take a close-up photo and zoom in
• Copy the characters exactly (including dashes)

Why it matters

MTD operator’s manuals often cover multiple similar models, and parts can vary by production run. Using the exact model number and serial number helps ensure you get the right belt, cable, chute parts, and hardware for your specific machine.

For model-plate details and recording fields, use the 31A-240-752 owner's manual.

The MTD 31A-240-752 snow thrower has an average useful life of 7 years or about 60 operating hours. After that point, we recommend replacing the machine or having it inspected annually to confirm the mechanical and safety systems are still in good condition (see the 31A-240-752 owner's manual).

What “average useful life” means

This is a benchmark for typical homeowner use and maintenance. It helps you plan for wear items like belts, scraper components, and auger parts that naturally degrade with time and use.

Typical wear items to watch

• Drive and auger belts for glazing, cracking, or slipping
• Scraper blade and skid surfaces for uneven wear
• Auger paddles and auger assembly for damage or excessive play
• Cables and springs for stretching or binding
• Wheels and hardware for looseness or wobble

When to repair vs. replace

If the engine runs well and the auger/drive system is solid, replacing common wear parts can extend performance. If multiple major systems are worn at once, replacement is usually the better value.

Situation	What we recommend	Why it matters
Unit is under 7 years and runs well	Replace worn wear parts as needed	Restores throwing and drive performance
Near 7 years or around 60 hours	Annual inspection and targeted repairs	Prevents safety issues from worn components
Past useful life with repeated failures	Consider replacement	Reduces downtime during storms

Parts that commonly support longer life

These model-matched parts are often involved when performance drops:

• Snowblower ground drive belt 754-0367 (loss of drive or slipping)
• MTD snowblower scraper blade 731-1033 (poor scraping, leaving snow behind)
• Chute spring 732-04111 (chute control not holding position)

Why it matters

A snow thrower that is past its average useful life can still run, but worn belts, cables, and auger components increase the chance of poor throwing performance and unexpected breakdowns when you need it most.
