Does Husqvarna use Kawasaki engines?
Yes. Husqvarna uses engines from multiple manufacturers across its mower lineup, and Kawasaki is one of the engine brands used on some Husqvarna models. For the Husqvarna 917376823 walk-behind mower specifically, the owner’s manual identifies a 173cc Kohler engine, not a Kawasaki.
Our documentation for Husqvarna model 917376823 lists:
- Engine brand: Kohler
- Displacement: 173cc
- Mower type: power-propelled 21-inch multi-cut walk-behind
For the exact engine details and maintenance specs (oil type, spark plug, tune-up intervals), use the owner's manual.
Husqvarna builds equipment with different engine options depending on the product line and model. Kawasaki engines are commonly found on many riding mowers, zero-turn mowers, and some commercial models, while walk-behind models often use other engine brands.
| Item you’re shopping for | Usually depends on | What to do on 917376823 |
|---|---|---|
| Air filter, spark plug, carburetor parts | Engine make and model | Match parts to the Kohler engine listed in the manual |
| Blade, wheels, drive belt, handle parts | Mower model number | Match parts to 917376823 parts diagrams |
| Drive system components | Mower model and drive design | Use the mower model parts list (belt, pulley, lever) |
Engine brand affects engine-specific maintenance and replacement parts. If you order ignition or fuel-system parts for the wrong engine family, they typically will not fit. Mower-deck and drive parts still match the mower model number.

What is e0 E10 gas for lawn mowers?
E0 and E10 describe how much ethanol is blended into gasoline for your Husqvarna 917376823 gas walk-behind lawn mower: E0 has 0% ethanol and E10 has up to 10% ethanol. This mower uses unleaded regular gasoline, and E10 is the common maximum blend used in many small engines; check the fuel guidance in the owner's manual.
- E0: ethanol-free gasoline (0% ethanol)
- E10: gasoline with up to 10% ethanol
- Higher blends (such as E15 or E85) are not intended for most walk-behind mower engines
- Ethanol blends can attract moisture during storage, which contributes to starting and running problems
The manual’s troubleshooting guidance for “does not start” includes stale fuel and water in fuel as common causes. Use these habits to avoid those problems:
- Buy fresh fuel in small quantities you will use soon
- Keep the fuel container tightly sealed to reduce moisture absorption
- If fuel is old, drain the tank and refill with fresh gasoline before troubleshooting deeper
- Store the mower only after the engine cools, and avoid storing it indoors with gasoline in the tank
- For seasonal storage, follow the storage steps in the owner's manual
| Fuel label | Ethanol content | Best use case in a mower |
|---|---|---|
| E0 | 0% | Best for storage and reducing ethanol-related issues |
| E10 | Up to 10% | Common everyday pump gas; use fresh and avoid long storage |
Using the right fuel blend helps your mower start easier, run smoother, and reduces carburetor and fuel-system issues caused by stale fuel or moisture. If your mower is already hard to start, fuel quality is one of the first things we check before replacing parts.

Is 500 hours a lot for a Husqvarna riding mower?
500 hours is a lot of use for any mower, but your Husqvarna 917376823 is a gas walk-behind lawn mower (not a riding mower). At 500 hours, it is normal to plan on more frequent maintenance and replacement of wear items; use the service intervals in the 917376823 owner's manual.
On a walk-behind mower, hours add up through repeated heat cycles, vibration, and debris exposure. At this point, performance depends mainly on maintenance history and whether common wear parts have been kept up.
Check these areas first:
- Cutting system: blade sharpness, blade balance, blade bolt tightness
- Drive system (if self-propelled): belt condition, pulley wear, drive control feel
- Engine basics: clean air filter, fresh fuel, correct oil level
- Deck and discharge: grass buildup under the deck, clogged bagging path
- Vibration sources: bent blade, damaged blade adapter, loose fasteners
These checks help you decide if the mower is still in good working shape:
- Starts without excessive pulling and runs smoothly at steady speed
- Cuts evenly without leaving strips or tearing grass
- Handle vibration stays low during mowing
- Self-propel (if equipped) pulls consistently without slipping
- No heavy grass buildup under the deck after cleaning and normal use
If you are chasing poor cut quality or vibration, the blade is the first wear item we replace.
| Symptom | Most common wear item | Example part for this model |
|---|---|---|
| Uneven cut, ragged grass, vibration | Blade | Lawn mower blade 532406712 |
| Slipping or no self-propel drive | Ground drive belt | Lawn mower ground drive belt, 3/8 x 32-3/4-in 532194149 |
| Speed control feels wrong or won’t hold setting | Throttle cable | Lawn mower throttle cable 532168552 |
Hours alone do not decide remaining life; maintenance does. The manual’s troubleshooting section ties symptoms like loss of power, uneven cut, and excessive vibration to correctable maintenance items, so staying on schedule keeps the mower reliable.
