What engine is on a Craftsman edger?
The engine on a Craftsman edger depends on the exact model. For Craftsman model 536797540, the engine is a small gas engine (carbureted) that uses common service parts like a primer bulb and carburetor components; the exact engine make and displacement are listed in the 536797540 owner's manual.
How to identify the exact engine on model 536797540
Use these quick checks to match the engine correctly before ordering parts:
- Check the engine shroud or valve cover for an engine brand badge (commonly Tecumseh or Briggs & Stratton on older Craftsman outdoor power equipment)
- Look for an engine model and spec number stamped on the blower housing or on an ID tag
- Match the carburetor style (primer bulb vs. choke) to the parts diagram
- Compare your carburetor parts to known items like the primer 36045A
- Confirm the fuel system type (float bowl carburetor vs. diaphragm carburetor)
What we typically see on Craftsman gas edgers
Most Craftsman walk-behind gas edgers in this family use a 4-cycle, pull-start, carbureted engine. If your edger starts only with priming, surges, or won’t stay running, the issue is often in the carburetor or fuel delivery.
Common engine-related parts for this model
| Symptom | Likely area | Example part for 536797540 |
|---|---|---|
| Hard starting, needs repeated priming | Primer/fuel pickup | Primer bulb |
| Starts then dies, runs lean/surges | Carburetor seals/air leak | Carburetor O-ring |
| Fuel leaking from carburetor | Float/needle/seat | Needle seat |
| Pull cord won’t retract or slips | Recoil starter | Starter assembly |
Why it matters
The engine make and spec determine the correct carburetor kit, gaskets, and starter parts. Matching the engine ID first prevents ordering the wrong primer bulb, needle seat, or rebuild kit.

What size blade does a Craftsman edger take?
For Craftsman lawn edger model 536797540, the edger blade is typically 9 inches long, about 2 inches wide, with a 1/2-inch round center hole. For the exact blade spec and hardware stack-up for your unit, use the 536797540 owner’s manual.
How to confirm the blade size on your edger
We recommend verifying the blade by measuring the old blade (or the blade guard opening) before ordering.
- Measure blade diameter/length across the cutting edge (tip to tip)
- Measure blade width (top to bottom of the blade body)
- Measure the center hole diameter (most commonly 1/2-inch on many Craftsman edgers)
- Check whether your blade uses washers/spacers that must be reused
- Inspect the blade for stamping that may show a size or part reference
Common Craftsman edger blade specs (quick reference)
These are the most common dimensions customers see on many Craftsman walk-behind edgers; your exact setup is confirmed in the manual.
| Spec to check | Typical value | Why you check it |
|---|---|---|
| Blade length/diameter | 9 in. | Ensures proper cutting depth and guard clearance |
| Blade width | 2 in. | Affects trench width and stability |
| Center hole | 1/2 in. round | Must match the arbor/spindle exactly |
| Blade thickness | Varies | Impacts fit with washers and clamp load |
If the blade will not fit or keeps loosening
A blade that does not seat flat or loosens usually points to worn mounting hardware or a bent guard area.
- Clean rust and packed dirt off the arbor and washers
- Replace damaged fasteners; a worn lock nut can back off under vibration (see lock nut 703251)
- Check the blade guard for bends; a misaligned guard can force the blade to run out
- Tighten the blade hardware firmly (follow the manual’s torque guidance)
- If vibration is severe, stop using the edger and inspect for a bent blade or spindle
Why it matters
Using the correct blade size on a Craftsman edger helps the blade track straight, prevents guard contact, and reduces vibration that can damage the spindle, fasteners, and belt drive.

Does Craftsman make a battery-powered edger?
Yes. Craftsman makes battery-powered (cordless) edgers, typically in the V20 (20V MAX) lineup. Your Craftsman model 536797540 is a gas edger, so cordless options are a separate product line; use the 536797540 owner's manual to confirm your current edger’s fuel and starting system.
What to look for in a Craftsman cordless edger
When you compare cordless models, focus on the specs that affect edging power and runtime.
- Battery platform: V20 (20V MAX) compatibility with your other Craftsman tools
- Runtime claims: how many feet of edging per charge (varies by grass type and depth)
- Blade size and depth adjustment range
- Weight and balance (important for long sidewalks and curbs)
- Included items: battery, charger, and replacement blade availability
Cordless vs gas edger: quick comparison
| Feature | Cordless (battery) | Gas (like 536797540) |
|---|---|---|
| Starting | Push-button or trigger | Pull-start recoil starter |
| Maintenance | Low (battery care, blade) | Higher (fuel, carburetor, starter) |
| Noise and exhaust | Lower | Higher |
| Best for | Light to medium edging | Heavy edging, longer sessions |
If your gas edger is hard to start, fix that first
Many shoppers consider cordless because a gas edger becomes difficult to start after storage. On model 536797540, these parts commonly affect starting and fuel delivery:
- Primer bulb: cracked or not pumping fuel (see primer 36045A)
- Carburetor wear or varnish: rebuild instead of replacing the whole unit (see carburetor rebuild kit 632592)
- Fuel line connection leaks: air leaks can prevent priming (see fuel line connector 632164)
- Recoil starter issues: rope not retracting or slipping (starter components may be involved)
Why it matters
Choosing between cordless and gas comes down to workload and upkeep. Cordless is convenient for routine edging; keeping your 536797540 tuned (primer, carburetor, fuel connections) restores reliable starts and full cutting power.
