What engine is in a Murray riding mower?
For a Murray riding mower, the engine brand and size depend on the exact model and production year. For the Murray 9-38600 front-engine lawn tractor, the engine is typically a single-cylinder or V-twin gasoline engine from a major small-engine maker; confirm the exact engine model by checking the engine ID label and then match parts on this model’s parts list or through Sears PartsDirect.
How to identify the exact engine on a Murray 9-38600
Look for the engine identification label (usually on the blower housing, valve cover, or near the starter). Record these items:
- Engine manufacturer (commonly Briggs & Stratton, Tecumseh, or Kohler on many Murray tractors)
- Engine model number
- Type and code (or spec number)
- Displacement (cc) or horsepower rating
- Serial number
Quick checks that help you match the right parts
Even when two tractors look similar, engine variants can change the correct fuel, ignition, and mounting parts.
- Compare the engine label numbers to the parts diagrams for Murray 9-38600
- Match by function first (fuel system, ignition, starter) and then by exact part ID
- If you are servicing the fuel line, use the correct clamp size and style; a common replacement is the clamp 791850
- If you are working around linkages or shafts, keep hardware organized; items like the retaining ring 11X7MA are easy to misplace
Common engine types you may see on Murray riding mowers
| Engine maker | Typical configuration | Where you’ll notice it |
|---|---|---|
| Briggs & Stratton | Single-cylinder or V-twin | Very common on many Murray tractors |
| Tecumseh | Single-cylinder | More common on older units |
| Kohler | Single-cylinder or V-twin | Often on higher-trim tractors |
Why it matters
The exact engine model determines the correct tune-up parts (spark plug, air filter, fuel line routing), starting system components, and even some mounting hardware. Identifying the engine label first prevents ordering the wrong parts and reduces no-start or hard-start issues.

Who makes Murray engines?
Most Murray riding mowers, including the Murray 9-38600 front-engine lawn tractor, are commonly equipped with Briggs & Stratton small engines. The exact engine manufacturer can vary by production run, so we recommend confirming by checking the engine ID tag on your tractor and matching parts by model.
How to confirm what engine you have
Look for the engine identification label (usually on the blower housing, valve cover area, or near the starter). Use these details to identify the engine maker and order the right tune-up and fuel system parts.
- Record the engine brand shown on the decal (often Briggs & Stratton)
- Write down the engine model, type, and code numbers
- Compare the engine label to your tractor’s parts breakdown for the correct fit
- If you are servicing the fuel line, replace worn clamps such as the clamp 791850
Quick ID guide (what to look for)
| What you see on the engine tag | What it means | Why it helps |
|---|---|---|
| Brand name (example: Briggs & Stratton) | Engine manufacturer | Confirms who made the engine |
| Model / Type / Code | Engine build identifiers | Ensures correct carburetor, filter, and ignition parts |
| Displacement (cc) or HP | Engine size | Helps match common maintenance parts |
Why it matters
Murray used multiple engine suppliers across different mower lines and years. Identifying the engine by its tag prevents ordering the wrong air filter, spark plug, carburetor parts, or fuel line hardware, and it speeds up troubleshooting when the engine clicks, spins, or will not start.

If your tractor is cranking issues are part of why you are checking the engine, follow the steps in riding lawn mower engine spins but wont start video to narrow down fuel, spark, and compression problems.

When did they stop making Murray lawn mowers?
Murray’s original lawn mower and lawn tractor manufacturing largely ended in 2005, when the company’s core production shut down after bankruptcy and an asset sale. The Murray name continued later through brand licensing, so you may still see newer “Murray” mowers even though the original Murray-built production had already stopped.
Quick timeline (what most owners mean by “stopped making them”)
- Before 2005: Murray manufactured many of its own riding mowers and lawn tractors.
- 2005: Original Murray production effectively ended (the point most people reference).
- After 2005: The Murray brand name continued under licensing arrangements, so “Murray” units could still be produced by other companies.
How this affects parts for your Murray 9-38600 lawn tractor
Even if the brand ownership changed later, parts support is typically based on the model number and the exact part ID, not the logo on the hood. For your Murray 9-38600 front-engine lawn tractor, match parts by the diagrams and the part listing for this model.
Common examples from this model’s parts list include:
| What to match | Where to look | Why it matters |
|---|---|---|
| Model number | Tractor ID tag (frame area) | Ensures you pull the correct diagrams |
| Part ID | Parts list for Murray 9-38600 | Prevents ordering a similar-looking but wrong part |
| Part condition | Compare old vs new | Avoids repeat failures from worn hardware |
Why it matters
Knowing the 2005 cutoff helps date the “original Murray” era, but repairs depend on your exact Murray 9-38600 configuration. Using the correct part ID is the fastest way to get the right fit and function.
To order parts shown for this model or search additional Murray parts by model number, use the parts list for this tractor or visit Sears PartsDirect.

What company makes Murray lawn mowers?
Murray lawn mowers have been produced under the Murray brand by different companies over time; for modern Murray-branded riding mowers and lawn tractors, the brand has been owned by Briggs & Stratton since 2004. For parts support on your Murray 9-38600 lawn tractor, we match replacements by the exact model number and the part ID.
Who actually “makes” a Murray mower?
Brand ownership and manufacturing can change across decades, so the most reliable way to identify what fits is to use the model number (9-38600) and the specific part ID.
Common scenarios we see:
- Briggs & Stratton-owned Murray (2004 to present): Murray is a brand under Briggs & Stratton.
- Older Murray equipment: May have been built by Murray Ohio Manufacturing or produced under licensing and private-label arrangements.
- Engines vs. tractors: The tractor brand and the engine brand can be different; many riding mowers use engines from major small-engine makers.
Why model number matching matters for parts
Even if two tractors both say “Murray,” they can use different hardware (fasteners, supports, adapters, fuel line clamps) depending on the production run.
Here are examples of parts we list for Murray model 9-38600:
Quick reference: brand vs. what you should use for ordering
| What you have | What it tells you | What to use to get the right part |
|---|---|---|
| Murray name on hood | Brand family | Model number 9-38600 |
| Engine label | Engine maker/model | Engine model and type code |
| Old part in hand | Exact match | Part ID and measurements |
Ordering tip
We recommend ordering from the parts list for your Murray 9-38600 first; if you are searching across models or looking up a part by number, use Sears PartsDirect.
Why it matters
Using the exact model number and part ID prevents returns and downtime, especially for fit-critical items like a retaining ring, support bracket, or fuel line clamp.

Is it worth replacing a lawn mower engine?
Yes, replacing the engine on your Murray 9-38600 lawn tractor is worth it when the deck, frame, steering, and transmission are still solid and the total cost stays well below the price of a comparable replacement tractor. If the deck is rusted through or the drivetrain is failing, the money is better spent elsewhere.
Quick decision checklist
Use these checkpoints before you commit to an engine swap:
- Deck shell is not cracked, bent, or rusted through
- Transmission pulls strongly; no constant belt slip
- Steering and front axle have minimal play and track straight
- You can still get common wear parts for the tractor
- Total cost (engine + tune-up parts + incidentals) stays under about 50% of a similar replacement mower
Cost and value comparison
| Situation | Best move | Why it matters |
|---|---|---|
| Deck and chassis are in good shape; engine is the main failure | Replace engine | Extends service life without buying a whole tractor |
| Deck is rusted/cracked or frame is structurally weak | Replace tractor | The deck and chassis drive long-term reliability |
| Engine swap cost is close to a replacement unit | Replace tractor | Near-new cost without a new drivetrain and deck |
Check these items first (they can mimic “bad engine”)
We recommend ruling out common no-start causes before pricing an engine:
- Battery condition and cable corrosion
- Starter/solenoid clicking and starter engagement
- Fuel quality and fuel line security (a loose clamp can cause fuel starvation)
- Safety interlock switches (seat, brake, PTO)
For click-no-start troubleshooting steps, use riding lawn mower engine clicks but doesnt turn over video.
Small parts that often come up during engine-related repairs
If you are repairing fuel delivery or reassembling linkages, these parts are commonly needed:
- Clamp 791850 (engine fuel line clamp)
- Retaining ring 11X7MA (retaining ring)
You can order parts from the list for Murray 9-38600, or search by model number on Sears PartsDirect.
Why it matters
An engine swap only pays off when the tractor’s deck and drivetrain are still worth investing in; otherwise, you risk fixing the engine and immediately chasing bigger, costlier failures.
