How much does it cost to repair a hydrostatic transmission on a lawn mower?
Hydrostatic transmission repairs are typically a riding-mower cost, not a walk-behind cost. Your Craftsman walk-behind mower model 917388932 uses a belt-and-cable drive system, so “hydrostatic transmission repair” usually does not apply; most drive issues are fixed by servicing the drive cable, belt, or related hardware listed in the owner's manual.
What you can expect to pay (typical ranges)
Hydrostatic transmissions are most common on riding mowers and lawn tractors. Typical cost ranges depend on whether you are repairing a leak or replacing the entire transaxle.
| Repair scenario (riding mower) | Typical parts cost | Typical total cost with labor |
|---|---|---|
| Minor service (fluid leak, linkage adjustment) | $50 to $300 | $150 to $600 |
| Pump or internal repair (limited availability) | $200 to $800 | $500 to $1,500 |
| Full transmission or transaxle replacement | $600 to $1,300 | $1,200 to $2,500 |
If your 917388932 “won’t move”, check these first
These are the most common causes on a self-propelled walk-behind mower:
- Drive (zone control) cable stretched, kinked, or broken; replace the lawn mower zone control cable 532183281
- Handle hardware loose so the control does not fully engage; inspect the handle bolt 532191574 and handle brackets
- Debris buildup under the deck creating drag (especially in heavy grass)
- Blade area damage after impact; inspect the blade adapter 532418373 and blade mounting hardware
- Wheels or height adjusters binding; clean and lubricate per the owner's manual
Why it matters
Hydrostatic transmission replacement can be one of the most expensive mower repairs, so it is important to confirm the mower type first. For model 917388932, focusing on the self-propel drive controls and deck drag points you to the repairs that actually restore forward motion.
Quick decision guide
- Riding mower with hydrostatic drive: use the cost table above.
- Walk-behind mower like 917388932: troubleshoot the drive cable, handle engagement, and deck drag before buying major parts.

How old is my lawn mower by serial number lookup?
Your Craftsman walk-behind mower model 917388932 does not use a universal serial-number-to-year format printed in the manual; instead, we use the serial number mainly to identify the exact production run. For the most accurate age estimate, match the serial number on the rear housing decal to the identification guidance in the 917388932 owner's manual and compare it to any recorded purchase date.
Where to find the serial number on model 917388932
The serial number is on a decal on the rear of the lawn mower housing.
- Tip the mower only as directed in the manual (to avoid oil or fuel issues)
- Wipe the rear housing clean so the decal is readable
- Record the model number (917388932) and the serial number exactly
- If the decal is damaged, look for any secondary ID labels on the deck or handle supports
How to estimate the mower’s age using what you have
Use these practical checks to narrow down the timeframe:
- Purchase date: Many owners wrote the purchase date in the manual or kept the receipt
- Engine model: This mower commonly uses a Briggs and Stratton engine (the manual shows 122K02-0577-E1); engine ID data can help narrow production era
- Parts history: If you have records of blade, cable, or handle replacements, the earliest service date is a strong clue
- Decal style and safety labels: Label designs often change over time, which can help bracket the age
Quick reference: what information helps most
| What you check | Where to find it | How it helps |
|---|---|---|
| Serial number | Rear housing decal | Identifies the production run |
| Date of purchase | Your records or manual notes | Best indicator of “how old” in real use |
| Engine model/type | Engine shroud label, manual | Helps narrow the manufacturing timeframe |
| Maintenance history | Receipts, notes | Establishes earliest known in-service date |
Why it matters
Knowing the approximate age helps us choose the right maintenance parts and specs for your mower, such as the correct blade hardware torque and common wear items like the blade adapter 532418373 or the zone control cable.

How to find Craftsman model number?
On the Craftsman walk-behind mower model 917388932, the model and serial numbers are printed on a decal on the rear of the lawn mower housing. Once you have that model number, you can match the correct parts list and diagrams in the owner's manual.
Where to look on model 917388932
Check these common spots in this order:
- Rear of the mower deck or rear housing area (look for a decal/label)
- Top of the deck near the engine mounting area
- Side of the deck near the discharge chute opening
- Handle support area (near the handle brackets)
- Under heavy grass buildup (wipe the deck clean to reveal the label)
What to write down (and why)
Record both numbers so you can identify the exact version of your mower.
| Item | What it’s used for | Example format |
|---|---|---|
| Model number | Ensures you get the correct diagrams and parts | 917.388932 |
| Serial number | Helps match production run changes | Varies by unit |
| Date of purchase | Useful for maintenance records | Month/Year |
Why it matters
Craftsman walk-behind mowers can look similar across multiple model numbers, but parts like the blade adapter, zone control cable, and handle hardware can differ. Using the exact model number from the rear housing decal helps prevent ordering the wrong replacement part.
Quick tip if the label is hard to read
- Clean the rear housing/deck with a damp rag and mild detergent
- Use a flashlight at a low angle to make faded printing easier to see
- Take a close-up photo and zoom in to read the characters

Should I use 87 or 89 gas for lawn mower?
For the Craftsman lawn mower model 917388932, use regular unleaded 87-octane gasoline for normal operation; higher octane (like 89) does not improve power or reliability in typical small 4-cycle mower engines. Follow the fuel and safety guidance in the owner's manual.
What to use (and what to avoid)
- Use fresh, clean, unleaded gasoline (87 octane).
- Avoid old gas (especially fuel that has been sitting for weeks or months).
- Avoid getting gasoline on tires, wheels, or painted surfaces; wipe spills promptly.
- Do not mix oil into the gas on this mower; it uses a 4-cycle engine.
- If you store fuel, use a fuel stabilizer to help prevent varnish and hard starting.
Why 87 is the right choice
Small walk-behind mower engines are designed to run at their specified compression ratio on regular fuel. Higher octane mainly resists knock in high-compression engines; it typically does not make a mower start easier, run smoother, or cut better.
Quick comparison: 87 vs 89 for a walk-behind mower
| Fuel choice | When it makes sense | What you should expect |
|---|---|---|
| 87 octane (regular) | Everyday mowing | Normal starting, power, and performance |
| 89 octane (mid-grade) | Only if your manual specifically calls for it | Usually no noticeable benefit |
Why it matters
Using the correct fuel helps prevent common problems like hard starting, rough running, and carburetor deposits. Fuel quality matters more than octane for most mower issues.
