Is it cheaper to repair or replace a lawnmower?
For a Craftsman 917276641 riding lawn tractor, it’s cheaper to repair when the fix is a normal wear item (blade, belt, pulley, solenoid) and the tractor is otherwise solid. Replace the mower when repair cost is about half (or more) of the price of a comparable new tractor, or when the engine or transmission has major internal failure.
Quick rule of thumb we use
- Repair if the issue is maintenance or a single failed part (belt, blade, battery/starting circuit, deck hardware).
- Replace if you’re facing repeated breakdowns, severe rusted deck/chassis, or major engine or transmission work.
- Decide faster by pricing the parts plus labor time, then comparing to a new tractor’s cost.
Common repairs that are usually worth it on model 917276641
These problems are typically straightforward and cost-effective compared to replacing the whole tractor:
- Mower blades will not rotate due to a worn belt or frozen pulley/mandrel (the manual calls out belt, idler pulley, and mandrel checks).
- Poor cut or uneven cut from worn or bent blades, deck buildup, or deck leveling needs.
- No-crank or clicking start issues tied to battery connections, fuse, wiring, ignition switch, solenoid, or starter.
Example parts that often solve “repairable” problems
| Symptom | Likely repair area | Example part for this model |
|---|---|---|
| Blades won’t spin | Deck drive system | Husqvarna lawn tractor belt, 1/2 x 101-1/6-in 592855001 |
| Uneven cut, vibration | Blade/mandrel area | Lawn tractor mandrel housing 587819701 |
| Clicking, no crank | Starting circuit | Lawn tractor starter solenoid 582042802 |
Why it matters
A riding mower like the Craftsman 917276641 is designed to be serviced. Replacing wear parts on schedule (belts, blades, pulleys, battery cables) restores cut quality and reliability for far less than the cost of a new tractor.
What to check before you spend money
Use the troubleshooting steps in the 917276641 owner’s manual and confirm:
- Battery condition and clean, tight terminals
- Fuse condition
- Wiring connections (especially at the solenoid and ignition switch)
- Deck underside is clean; vent holes around mandrels are clear
- Belts are routed correctly and not glazed, cracked, or stretched

What are the parts of a riding lawn mower called?
On the Craftsman 917276641 riding lawn tractor, the “parts” are typically grouped into engine, cutting deck, drive/steering, electrical, and operator controls. In our experience, the most commonly referenced items are the controls (clutch/brake, throttle/choke, ignition), the mower deck components (blades, mandrels, belt), and the starting/charging parts.
Common riding mower part names (and what they do)
Here are the names you will see most often in diagrams and troubleshooting for a front-engine tractor like model 917276641:
- Operator controls: clutch/brake pedal, parking brake, throttle/choke control, ignition switch, attachment clutch lever, motion control lever
- Cutting system (mower deck): blades, mandrel (spindle) assemblies, deck housing, idler pulleys, mower drive belt
- Drive and steering: transmission, freewheel control, front axle, steering linkage
- Electrical: battery, starter solenoid, ignition harness, headlight circuit (if equipped)
- Fuel and air: fuel tank, fuel lines, carburetor, air filter
For the exact control names and locations used on your tractor, use the 917276641 owner's manual.
Examples of model-matched parts you may see on this tractor
These are real part names that commonly come up when customers ask “what is that part called?”
| System | Example part name | What it affects |
|---|---|---|
| Cutting deck | Lawn tractor mandrel housing 587819701 | Blade support and rotation (deck spindle area) |
| Cutting deck | Mandrel pulley 532195945 | Transfers belt power to the mandrel |
| Starting | Lawn tractor starter solenoid 582042802 | Sends battery power to the starter |
| Deck drive | Husqvarna Lawn Tractor Belt, 1/2 X 101-1/6-in | Turns blades or drives system (by routing) |
Why the “right name” matters
Using the correct part name helps you match the right diagram, troubleshoot faster, and avoid ordering the wrong item. For example, “blade won’t spin” often points to the mower drive belt, idler pulley, or a frozen mandrel, while “engine clicks” points you toward the battery, solenoid, or wiring.
Quick tip: match the symptom to the system
- Blades will not rotate: check belt routing/tension, idler pulleys, mandrels
- Poor cut or uneven cut: check blade condition, deck level, debris buildup under deck
- No crank or clicking: check battery connections, solenoid, safety interlocks
- Loss of drive: check freewheel control position and drive belt condition

What model number is a Craftsman 6.75 lawn mower?
A “Craftsman 6.75” is usually a walk-behind mower, not our Craftsman riding tractor model 917276641. For the common 21-inch Craftsman 6.75-hp rotary walk-behind mower, the model number is typically 917.377911; confirm by matching the ID tag on your mower to the 917276641 owner’s manual.
Where to find the model number on your mower

- Check the rear of the deck near the discharge chute
- Look under the seat area (on some units) or behind the engine
- Check the handle support brackets or frame rail
- Write down the entire number, including dots and suffixes
- Use the model number (not engine HP) to choose parts like blades and belts
Quick comparison: 6.75 mower vs 917276641 tractor
| Item | Walk-behind “6.75” mower | Craftsman 917276641 tractor |
|---|---|---|
