Craftsman 917385123 lawn mower Parts

Hydrostatic transmission repairs are typically a riding-mower cost category; the Craftsman 917385123 is a gas walk-behind mower and normally does not use a hydrostatic transmission. For walk-behind drive problems, the repair cost is usually much lower and often involves cables, wheels, or deck hardware instead of a transmission.

What you can expect to pay (typical ranges)

Hydrostatic transmission work usually applies to riding mowers and garden tractors.

• Hydrostatic transmission replacement (riding mower): commonly $1,300 to $2,500 installed
• Hydrostatic transmission repair (riding mower): often several hundred dollars depending on parts and labor
• Walk-behind mower drive issue (this model type): commonly $30 to $200 for parts, plus labor if you hire service

Mower type	Likely “transmission” type	Typical repair scope	Typical cost range
Walk-behind mower (Craftsman 917385123)	Belt/cable/wheel drive components	Cable adjustment, wheel/drive parts	$30 to $200 + labor
Riding mower	Hydrostatic transaxle	Replace transaxle or internal repair	$1,300 to $2,500 installed

How to tell if your mower actually has hydrostatic drive

On a hydrostatic riding mower, you usually see a forward/reverse pedal or lever controlling speed smoothly (no shifting). On a walk-behind mower like the 917385123, drive issues are more often tied to the handle controls and wheel drive components.

• Drive control feels loose or does not engage
• Mower pulls intermittently or slips under load
• Wheels do not turn even though the engine runs
• Cable routing is kinked, stretched, or out of adjustment

For model-specific adjustment and service checks, follow the 917385123 owner's manual.

Common lower-cost fixes for “won’t move” symptoms on walk-behind mowers

If your Craftsman 917385123 will not self-propel, start with the simple mechanical items that fail most often.

• Inspect the wheel assemblies for wear or binding
• Check the drive control cable for damage and proper routing
• Verify fasteners at the handle and brackets are tight
• Confirm the blade and deck area are not packed with debris (drag can feel like drive failure)

If you are replacing a wheel, match the exact assembly used on this model, such as the lawn mower wheel assembly 583720201.

Why it matters

Hydrostatic transmission repairs can be expensive, so confirming the mower type first prevents overpaying for the wrong diagnosis. On the Craftsman 917385123, most “drive” complaints are resolved with adjustments or common wear parts rather than a transmission replacement.

Your Craftsman walk-behind mower model 917385123 uses a model and serial decal on the rear of the mower housing. The serial number identifies your specific unit, but the most reliable way to determine the mower’s age is to match that serial number to the date-code format shown in the 917385123 owner's manual.

Where to find the serial number on model 917385123

Look for a decal on the rear of the lawn mower housing (behind the deck area). We recommend writing it down exactly as shown.

• Check the rear of the mower housing for the decal
• Record the serial number and your date of purchase
• Copy letters and numbers exactly (no spaces added)
• If the decal is dirty, wipe it gently so every character is readable

How to estimate the build date from the serial number

Many outdoor power equipment serial numbers include a date code, but the format varies by manufacturer and production run. Use these practical checks:

• Look for a 6-digit block that resembles a date (common patterns include MMDDYY or YYMMDD)
• If you see a 4-digit block, it often represents month and year (for example, MMYY or YYMM)
• Compare the decoded date to your purchase date; the build date is typically earlier
• If the serial includes multiple number groups, the first group is often the date code

Quick date-code cheat sheet (common formats)

What you see in the serial	Often means	Example interpretation
6 digits like 031524	MMDDYY	March 15, 2024
6 digits like 240315	YYMMDD	March 15, 2024
4 digits like 0921	MMYY	September 2021

Why it matters

Knowing the mower’s age helps us match the correct Craftsman parts and maintenance schedule for your 22-inch deck mower, especially wear items like the blade, blade adapter, and hardware.
