How much does it cost to repair a hydrostatic transmission on a lawn mower?
Hydrostatic transmission repairs are a riding-mower issue; your Craftsman 917376301 is a walk-behind mower that uses a belt-and-gear drive system instead of a hydrostatic transmission. For this model, repair costs usually center on the drive belt, gearcase parts, or drive control adjustments shown in the owner's manual.
For a walk-behind mower like the Craftsman 917376301, costs usually fall into these buckets:
- Drive belt replacement: typically $30 to $120 total (part plus labor)
- Drive control/cable or linkage service: typically $50 to $150
- Gearcase internal repair or replacement: typically $120 to $350 (more if multiple internal parts are worn)
- Full “won’t move” diagnosis and tune-up add-ons: typically $80 to $200
If you are pricing a hydrostatic transmission (again, usually on riding mowers), the transmission unit and labor can run hundreds to a couple thousand dollars depending on mower type and whether the transaxle is replaced as an assembly.
If your mower drives poorly, slips, or will not self-propel, these parts are common suspects:
- Belt 532157769 (worn, stretched, glazed, or oil-soaked)
- Control 532184588 (drive control assembly issues)
- Gearcase internal wear (gears, bushings, bearings)
- Wheel/drive hardware wear (washers, E-rings, dust covers)
| Symptom | Most common cause | What we check first |
|---|---|---|
| Mower will not self-propel | Belt slipping or broken | Belt condition and routing |
| Moves but slips under load | Belt worn or pulley issue | Belt and engine pulley |
| Grinding/clicking from drive | Gearcase wear | Gearcase gears/bearings |
| Drive lever feels loose | Control/linkage issue | Drive control assembly |
Hydrostatic transmissions are expensive because they are sealed hydraulic drive systems. Your 917376301 is typically cheaper to fix because most drive problems are mechanical (belt, pulley, gearcase), and many repairs are straightforward once the worn part is identified.
Use the troubleshooting and drive system sections in the owner's manual, then compare the symptoms to the parts list for your model. If the gearcase is noisy or binding, plan for a higher repair total than a simple belt swap.

Is it cheaper to repair or replace a lawn mower?
It’s cheaper to repair your Craftsman lawn mower model 917376301 when the fix is routine maintenance or a single worn part. Replace the mower when repair costs approach about half the price of a comparable new mower, or when the engine or drive system has major damage.
- Repair when the mower starts and runs well but has a wear item issue (blade, belt, wheel, primer bulb).
- Repair when the problem is isolated and parts are readily available.
- Replace when the engine has severe internal damage (low compression, crankshaft damage) and labor plus parts are high.
- Replace when the drive system needs multiple major parts and the deck or frame is also worn.
- Replace when you need features your current mower cannot support (different cut width, self-propel type, bagging setup).
These are typical “high value” fixes because they restore performance without major teardown:
- Replace a worn or bent blade: lawn mower blade 532406713
- Replace a slipping self-propel belt: belt 532157769
- Fix drive control issues: control 532184588
- Replace a cracked primer bulb (hard starting): primer 36045A
- Refresh the carburetor (fuel varnish, surging): carburetor 632671C
| Situation | Typical complexity | Usual best choice |
|---|---|---|
| Blade is dull/bent, mower vibrates | Low | Repair |
| Self-propel won’t pull, belt worn | Low to medium | Repair |
| Won’t start after storage, fuel issue | Medium | Repair |
| Major engine internal failure | High | Replace |
| Multiple systems failing (engine + drive + deck) | High | Replace |
A walk-behind mower like the 917376301 is designed for regular maintenance. The owner’s manual calls out routine service and wear items (such as blades and belts) as normal upkeep, so repairing those items usually delivers the best value over replacing the whole mower. Check the maintenance and troubleshooting sections in the owner's manual before you decide.

Should I use 87 or 89 gas for lawn mower?
For your Craftsman walk-behind mower model 917376301, use regular unleaded gasoline with a minimum of 87 octane. Using 89 octane is fine, but it does not improve performance in this mower when the manual already specifies 87 minimum; fresh fuel matters more than higher octane (see the owner's manual).
- Use fresh, clean, regular unleaded gasoline (87 octane minimum).
- Do not mix oil with gasoline (this mower uses separate engine oil in the crankcase).
- Buy only what you can use in about 30 days to keep fuel from going stale.
- In cold weather (below 32°F / 0°C), use fresh winter-grade gasoline for easier starting.
- If the mower will sit 30 days or longer, run it dry or drain the fuel system for storage.
| Fuel choice | Works in 917376301? | What you may notice | Best use case |
|---|---|---|---|
| 87 octane (regular) | Yes (recommended) | Normal power and starting | Everyday mowing |
| 89 octane (mid-grade) | Yes | Typically no difference | If 87 is unavailable |
Small-engine fuel systems are sensitive to stale fuel and moisture. The manual warns that alcohol-blended fuels can attract moisture, which can lead to separation and acids during storage; that is why fuel freshness and proper storage prevent hard-starting and carburetor problems more than stepping up from 87 to 89.
These fuel-related checks solve most no-start complaints:
- Drain old fuel and refill with fresh 87 octane.
- Check for water-contaminated fuel (drain tank and carburetor, then refill).
- Inspect the primer bulb for damage (if equipped); replace the primer 36045A if it is cracked or won’t pump.
- If the pull cord is stuck, follow the steps in lawn mower pull cord stuck.

What year is Craftsman Model 917376301?
Craftsman lawn mower model 917376301 does not have a single built-in “model year” the way cars do; the most reliable way to date your specific mower is by using the serial number and the identification decal location shown in the owner's manual.
The model number (917376301) identifies the mower design, but the serial number identifies your specific unit.
- Look for the decal on the rear of the lawn mower housing.
- Record the serial number exactly as shown.
- Also record the date of purchase if you still have it (receipt, warranty paperwork).
- Use the serial number when ordering parts or confirming production details.
According to the documentation for this mower, the identification decal is on the rear of the mower housing.
| Item | What it tells you | Where to find it |
|---|---|---|
| Model number: 917376301 | Which Craftsman walk-behind mower design you have | Rear housing decal |
| Serial number | Which exact unit you own (best for dating) | Rear housing decal |
| Engine model number | Which engine version is installed | On the engine blower housing |
Walk-behind mowers like this Craftsman model often stay in production across multiple seasons with small running changes. That is why the serial number and purchase date are the practical way to pin down when your mower was made and put into service.
If you are already inspecting the mower, it is a good time to check common wear items that affect cut quality and drive performance:
- Blade condition (bent, cracked, or dull)
- Blade mounting hardware and adapter fit
- Drive belt wear and glazing
- Wheel and height adjuster condition
For example, a worn blade or adapter can cause vibration and poor cutting; the parts list for this model includes items like the lawn mower blade 532406713 and lawn mower blade adapter 581547901.
Using the correct identification (model number plus serial number) helps ensure you get the right Craftsman parts, diagrams, and service procedures for your exact 917376301 mower.
