How much does it cost to repair a hydrostatic transmission on a lawn mower?
The Craftsman 917387601 is a gas walk-behind mower, and walk-behind mowers typically do not use a hydrostatic transmission. If your mower is not self-propelled, there is no transmission repair cost; if it is self-propelled, costs usually relate to the drive belt, cable, or wheel drive parts instead.
What you are likely dealing with on model 917387601
On this Craftsman walk-behind platform, “won’t move” or “won’t self-propel” problems are usually caused by a control/cable issue, a worn drive component, or a wheel/height hardware problem rather than a hydrostatic unit.
Common repair targets:
- Drive control or zone control cable adjustment or replacement
- Worn or damaged wheel components
- Loose or missing fasteners at the handle or wheel brackets
- Blade and blade adapter service (if vibration or stalling is part of the complaint)
Typical cost ranges (parts and labor)
Pricing varies by region and shop minimums, but these ranges are typical for walk-behind mower drive repairs.
| Repair type (walk-behind) | Typical parts cost | Typical labor cost | Notes |
|---|---|---|---|
| Cable replacement/adjustment | $15 to $50 | $50 to $150 | Often restores self-propel function |
| Wheel/drive hardware repair | $10 to $75 | $50 to $200 | Depends on what is worn or seized |
| Major drive system overhaul | $50 to $200+ | $150 to $350+ | Usually not called “hydrostatic” on walk-behinds |
Parts that commonly come up for this model
If your symptom is “engine runs but mower won’t move,” start with the control cable and wheel-related parts.
Helpful model-matched parts:
- Husqvarna poulan lawn mower zone control cable 532168552
- Lawn mower wheel 532189159
- Wheel bracket 532407494
Why it matters
Hydrostatic transmission pricing (often discussed for riding mowers) can be much higher than walk-behind drive repairs. Identifying whether you have a self-propel drive issue versus a true hydrostatic transmission issue prevents overpaying and helps you buy the right Craftsman parts the first time.
Where to confirm your drive system
Use the 917387601 owner's manual to verify whether your mower is self-propelled and to follow the correct adjustment and service steps for your specific configuration.

What happens if you put premium gas in a lawn mower?
Putting premium gas in a Craftsman 917387601 gas walk-behind lawn mower typically causes no harm and usually provides no performance benefit; what matters most is using clean, fresh gasoline and avoiding fuel that causes deposits or starting problems. Follow the fuel and storage guidance in the 917387601 owner's manual.
What you may notice (and what it means)
- No change in power or cut quality: The engine speed is factory-set for optimum performance and is not adjustable.
- Same starting behavior: Hard starting is more often tied to stale fuel, water in fuel, or a dirty air filter.
- Higher cost per tank: Premium fuel generally costs more without improving mowing results.
- Fewer fuel-related issues when fuel is fresh: Fresh fuel helps prevent “won’t start” symptoms linked to stale fuel.
Fuel tips that prevent most “won’t start” problems
The manual’s troubleshooting list points to fuel quality and basic maintenance as common causes of no-start conditions.
- Use fresh gasoline (do not store gasoline from one season to another).
- Keep the gas can clean and rust-free; rust and dirt in gasoline cause problems.
- If the engine is flooded from over-priming, wait a few minutes and try starting again without additional priming.
- Replace the air filter on schedule (a dirty filter can keep the engine from running properly).
- Keep the mower clean; built-up grass and debris can make the engine run hotter and shorten engine life.
Quick comparison: premium vs regular gas in a mower
| Fuel choice | What it changes | What it does not change |
|---|---|---|
| Regular unleaded | Normal operation when fresh and clean | Engine speed setting, cutting performance when the mower is healthy |
| Premium unleaded | Usually no practical difference besides cost | Does not “fix” stale fuel, water in fuel, or maintenance issues |
Why it matters
Most fuel-related mower problems come from stale fuel, contamination, or storage habits, not octane rating. Using fresh gas and storing the mower safely helps prevent starting issues and protects the engine over the season.

What model number is a Craftsman 6.75 lawn mower?
A “Craftsman 6.75” label usually refers to the engine series, not a single mower model number. For the Craftsman walk-behind mower on this page, the model number is 917.387601 (often written without the dot as 917387601); you can confirm it on the ID label and in the 917387601 owner's manual.
Where to find the model number on the mower
Look for the mower model number on the mower housing or rear deck area, typically on a sticker or stamped plate.
- Check the rear of the deck near the height adjusters
- Look under the handle mounting area
- Clean grass and debris off the label so all digits are readable
- Write the number exactly as shown (including dots if present)
- Use the mower model number (not the engine number) when ordering parts like a blade or cable
“6.75” vs. mower model number (quick comparison)
| What you see | What it usually means | What to use for parts |
|---|---|---|
| 6.75 (or 6.75 HP) | Engine power/series marketing label | Mower model number (example: 917.387601) |
| 917.387601 | Craftsman mower model number | Use this to match diagrams and parts |
| Engine model number | Engine identification (separate from mower) | Use for engine-specific parts only |
If you are trying to match a different “Craftsman 6.75” mower
Many Craftsman mowers can be described as “6.75,” so the correct model number depends on the exact unit.
- Match the full model number from the mower label
- Compare deck size and discharge style (side discharge vs. bagging)
- If you need common wear parts, start with the blade and control cable for your exact model
Common parts customers replace on model 917387601
- Lawn mower blade 532406713 (blade wear, poor cut)
- Husqvarna poulan lawn mower zone control cable 532168552 (engine won’t stay running when you release the bar)
- Lawn mower blade adapter 532418373 (blade wobble or stripped mounting)
Why it matters
Using the correct mower model number prevents ordering the wrong Craftsman parts, especially for deck components (blade, adapter, discharge chute hardware) that vary between similar-looking 6.75-series mowers.
