What model number is a Craftsman 6.75 lawn mower?
A “Craftsman 6.75” is typically a walk-behind mower, not a riding tractor. The model on this page is Craftsman 917276700, which is a 24.0 HP, 48-inch front-engine lawn tractor; confirm your exact mower’s model from the ID label and the 917276700 owner's manual.
Look for the model/product ID label on the machine and match it exactly (including all digits).
- Walk-behind mowers: check the rear deck, near the wheels, or behind the engine
- Riding mowers/tractors: check under the seat, on the frame rail, or near the engine compartment
- Write down the full model number and any product number
- Use the label, not the engine cover decal (horsepower decals are often generic)
- If the label is worn, lightly clean it and use a flashlight to read stamped characters
“6.75” usually refers to an engine rating used across many Craftsman walk-behind mowers, so multiple different models can share that marking.
| Marking you see | What it usually means | What you need for parts |
|---|---|---|
| 6.75 | Engine rating/series | Full mower model number from the ID label |
| 917276700 | Tractor model number | Tractor parts and diagrams for this exact unit |
| 48" | Deck size (tractor) | Deck and blade-drive parts matched to the model |
Craftsman 917276700 is a riding lawn tractor (24.0 HP, 48-inch mower deck). For common deck-drive issues (noise, wobble, uneven cut), a frequent wear item is the mandrel assembly; the correct match shown for this model is the lawn tractor mandrel housing 587819701.
Using the exact model number prevents ordering the wrong blades, belts, pulleys, or electrical parts (like a starter solenoid or PTO switch) that can look similar across Craftsman equipment.

Is it worth replacing a lawn mower engine?
Yes, replacing the engine on your Craftsman lawn tractor model 917276700 is worth it when the deck, transmission, and chassis are in solid shape and the total engine swap cost stays well below the cost of a comparable new tractor. If multiple major systems are worn out, replacement usually makes more sense.
- The mower deck is straight (no cracks) and cuts evenly after basic leveling
- The transmission drives smoothly (no slipping, no loss of pull)
- The frame and steering are tight (no severe rust-through or bent axle)
- You can do basic service safely (battery, fuel, belts, blades)
- The engine is the main failure, not a long list of other problems
We use this simple comparison to decide:
| If your total repair cost is... | Typical best choice |
|---|---|
| Under ~50% of a comparable new tractor | Replace the engine (or short block) |
| Around 50% to 70% | Decide based on deck/transmission condition |
| Over ~70% | Replace the tractor |
Use these checks to avoid replacing an engine when the real issue is elsewhere:
- Starting system: weak battery, dirty terminals, blown fuse, bad wiring, ignition switch, solenoid, or starter
- Fuel and tune-up items: stale fuel, dirty fuel filter, dirty air filter, fouled spark plug
- Safety controls: brake and attachment clutch must operate correctly
- Deck condition: clean underside, verify blades and belt drive are in good condition
For model-specific operating and safety guidance (including service cautions like not adjusting with the engine running), use the 917276700 owner's manual.
If you diagnose a no-crank or click-no-start condition, one common electrical replacement is the lawn tractor starter solenoid 582042802.
An engine swap can extend the life of a good Craftsman tractor for years, but it only pays off when the rest of the machine is safe and mechanically sound. Checking the starting circuit, fuel quality, and deck drive first prevents spending engine money on a non-engine problem.

What engine does Craftsman riding mower use?
For Craftsman lawn tractor model 917276700, the operator’s manual identifies it as a 24.0 HP tractor with a low-emission engine and electric start. The manual does not name a specific engine brand, so the most accurate way to confirm the exact engine make and model is to match the engine ID label to the specs in the 917276700 owner's manual.
Use these quick checks to get the engine make and model without guessing:
- Lift the hood and look for an engine ID sticker (often on the blower housing, valve cover, or near the starter)
- Record the model, type, and code (common on Briggs & Stratton labels) or the equivalent ID fields on other engines
- Compare those numbers to the engine information and service sections in the 917276700 owner's manual
- If the label is missing or unreadable, check for stamped numbers on the engine shroud or tag bracket
- Use the tractor model number 917276700 when shopping parts so you get the correct electrical and deck components
The engine brand and exact model determine the correct tune-up parts and service specs (spark plug type/gap, air filter style, oil capacity, and fuel system parts). It also helps diagnose starting problems accurately.
| Symptom | Most common area to check | Related part examples for 917276700 |
|---|---|---|
| Clicks but won’t crank | Battery cables, solenoid, safety switches | Lawn tractor starter solenoid 582042802 |
| Cranks but won’t start | Fuel, spark, choke use, stale gas | Air filter, spark plug (engine-specific) |
| Blades won’t engage | PTO switch, clutch, wiring | Switch.pto 582107601 |
If you’re troubleshooting a no-start or no-crank condition, follow a step-by-step process in riding lawn mower engine clicks but doesnt turn over video or riding lawn mower engine spins but wont start video.

How much does it cost to replace a riding lawn mower engine?
Replacing the engine on a Craftsman riding tractor like model 917276700 typically costs about $260 to $1,800 installed, depending on the engine type, labor rates, and whether related items (battery cables, belts, wiring) also need service. Engine replacement labor is commonly around 6 hours.
- Engine price (new or remanufactured; horsepower and shaft specs affect cost)
- Labor time (engine swap, alignment, test run)
- Extra parts often replaced at the same time (belts, pulleys, wiring, fuel line)
- Electrical starting issues discovered during diagnosis (battery, fuse, solenoid, starter)
- Shop fees and pickup/delivery (varies by area)
| Cost item | Typical range | Notes |
|---|---|---|
| Engine (part) | $200 to $1,400 | Biggest variable; depends on specs and brand |
| Labor | $300 to $900 | Often based on ~6 hours plus shop rate |
| “While you’re in there” parts | $20 to $250 | Belts, idlers, wiring repairs, fuel filter |
Many “dead engine” symptoms on riding mowers are caused by starting or safety circuits, not a failed engine. The troubleshooting steps in the 917276700 owner’s manual cover common no-start and no-crank checks such as:
- Depress the brake pedal and disengage the attachment clutch/PTO
- Check the battery condition and clean/tighten terminals
- Check/replace the fuse
- Inspect wiring connections
- Test/replace the solenoid or starter
If you hear a click but the starter does not turn, a failed solenoid is a common fix; the lawn tractor starter solenoid 582042802 is one of the model-matched parts we list for this tractor.
An engine replacement is one of the highest-cost repairs on a riding mower. Verifying the battery, wiring, fuse, PTO switch, and solenoid first can prevent paying for an engine when the real issue is an electrical or interlock problem.
