What's the average lifespan of a riding lawn mower?
Most riding lawn mowers, including the Craftsman 917287242 front-engine lawn tractor, typically last 10 to 15 years with normal residential use and consistent maintenance (oil changes, blade care, belt checks, and proper storage).
Typical lifespan ranges (what we see most often)
Lifespan depends mainly on hours of use, terrain, and maintenance habits.
- Light use (flat yard, maintained regularly): 12 to 15 years
- Moderate use (weekly mowing, mixed terrain): 10 to 12 years
- Heavy use (large acreage, hills, dusty conditions): 7 to 10 years
- Neglected maintenance or poor storage: 5 to 8 years
What usually wears out first
These are common wear items that affect performance long before the tractor itself is “done.”
- Deck drive components (blades, mandrels, pulleys)
- Belts that stretch, glaze, or crack
- Battery and starting circuit parts
- Steering and front axle wear points
- Tires and wheel hardware
Quick maintenance habits that extend life
Use the maintenance schedule and specs in the owner's manual as your baseline.
- Change engine oil and filter on schedule
- Keep the air filter clean (especially in dusty mowing)
- Sharpen or replace blades; avoid mowing over rocks and roots
- Keep belts properly routed and tensioned; replace when worn
- Store with clean deck, stabilized fuel, and a charged battery
Common parts that support long service life (examples)
If you are refreshing the deck or drive system on model 917287242, these are frequently replaced items.
| System | Example part | What it affects |
|---|---|---|
| Mower deck | Lawn tractor mandrel housing 587819701 | Smooth blade rotation, reduced vibration |
| Blade drive | Husqvarna lawn tractor blade drive belt 584453101 | Blade engagement and cut consistency |
| Ground drive | Lawn tractor ground drive or blade drive belt, 1/2 x 92-2/5-in 592855201 | Forward motion and traction under load |
Why it matters
A riding mower’s “lifespan” is mostly about keeping cutting and drive systems efficient. When belts slip, blades dull, or deck parts loosen, the tractor works harder, runs hotter, and wears faster. Staying ahead of routine service keeps your Craftsman tractor reliable season after season.

Is it worth fixing a riding lawn mower?
Yes, fixing a riding lawn mower is worth it when the tractor is structurally sound and the problem is limited to common wear items (belts, blades, electrical starting parts). For Craftsman model 917287242, many frequent repairs are straightforward and cost far less than replacing the tractor.
Quick way we decide: repair vs replace
- Repair if it needs routine parts like a deck belt, blade, pulley, or solenoid
- Repair if the engine runs well and the frame, steering, and deck are solid
- Replace if the tractor has major drivetrain damage, severe rust-through, or repeated failures across multiple systems
- Replace if repair cost is close to the price of a comparable replacement tractor
- Repair if you can do the work safely and follow the procedures in the 917287242 owner's manual
Typical “worth fixing” repairs for model 917287242
These are common, high-impact fixes that usually restore performance quickly:
- Replace a worn deck belt such as the husqvarna lawn tractor blade drive belt 584453101
- Replace a worn ground drive belt such as the lawn tractor ground drive or blade drive belt 592855201
- Replace a no-crank electrical part such as the lawn tractor starter solenoid 582042802
- Correct poor cut quality by leveling the deck, sharpening blades, and cleaning buildup under the deck (the manual calls out deck leveling, blade condition, and debris buildup as common causes of poor cutting)
Cost comparison (simple rule-of-thumb)
| Situation | What it usually means | Typical recommendation |
|---|---|---|
| One failed wear part (belt, blade, pulley) | Normal maintenance | Repair |
| Starting issue (clicks, no crank) | Often battery, wiring, solenoid | Repair |
| Loss of drive plus multiple worn components | Higher parts and labor | Compare total cost before repairing |
| Major transaxle or engine failure | High-cost repair | Replace unless you are restoring it |
Why it matters
A riding mower that is kept safe and maintained (tight fasteners, working safety devices, clean deck, proper tire pressure) cuts better and lasts longer. The troubleshooting guidance in the manual also shows that many “big” symptoms trace back to basic maintenance items, not catastrophic failures.
If you are ordering parts
We recommend ordering by exact model number (917287242) so you get the right belt length, blade style, and electrical connectors. You can order parts from the list for this model, or search by model number on Sears PartsDirect.

What size belt do I need for a Craftsman 42 inch deck?
For Craftsman model 917287242, the belt you need is identified by the belt’s part listing (not just deck width). On this model’s parts list, one belt is specified as 1/2 x 92-2/5 in; use the belt routing and callouts in the 917287242 owner’s manual to confirm you are replacing the mower (blade) belt versus the ground drive belt.
Pick the correct belt type first
A “42-inch deck” description is common across many tractors; belt length changes with pulley and idler layout. Before ordering, confirm which system you are servicing:
- Mower (blade) drive belt: turns the deck mandrels and blades
- Ground drive belt: drives the transmission from the engine
- Deck configuration: idler and keeper positions affect belt length
- Old belt markings: check for a printed part number on the belt’s outer edge
- Routing match: compare your routing to the diagram in the manual
Belt options shown for Craftsman 917287242
Use the part listing to match the correct belt; only one belt on this page includes a published size.
| Belt listing on this model page | What it’s used for | Size shown |
|---|---|---|
| Lawn tractor ground drive or blade drive belt, 1/2 x 92-2/5-in 592855201 | Ground drive or blade drive (as listed) | 1/2 x 92-2/5 in |
| Husqvarna lawn tractor blade drive belt 584453101 | Blade drive belt | Not specified in the listing |
Why it matters
A belt that is the wrong length or routed incorrectly slips, jumps off pulleys, and accelerates wear on idlers, belt keepers, and mandrel bearings. The correct belt keeps blade speed steady for a clean, even cut.
Practical replacement checks
Follow the belt replacement steps in the manual and verify these items during install:
- Belt fully seated in every pulley groove before raising the deck
- Idler pulleys spin freely and are not wobbling
- Belt keepers are not bent and have proper clearance
- Deck top is cleaned so debris does not push the belt out of alignment

What is the best 42 riding mower?
A 42-inch riding mower is the best choice when you need easier maneuvering around trees and beds but still want faster mowing than a walk-behind. Your Craftsman 917287242 is a front-engine lawn tractor that commonly uses a larger deck size; use the 917287242 owner's manual to confirm your exact deck and setup.
How we recommend choosing the best 42-inch rider
Focus on fit for your yard and long-term serviceability, not just brand name.
- Yard size: 42-inch decks fit most small to mid-size lawns efficiently
- Obstacles: tighter spaces favor a smaller deck and better turning control
- Terrain: slopes favor stable traction and a deck that can be leveled correctly
- Cut quality: easy cutting-height adjustment and consistent blade speed
- Maintenance: simple access to belts, blades, and spindles (mandrels)
- Parts support: choose a model with readily available wear parts
42-inch vs 46-inch deck: what changes
Many riders that look similar differ mainly by deck width; that affects time, trimming, and how often you scalp on uneven ground.
| Deck size | Best for | Tradeoffs |
|---|---|---|
| 42-inch | More obstacles, narrower gates, tighter turns | Slightly longer mow time on open lawns |
| 46-inch | More open lawn, fewer obstacles | Needs a bit more room to trim and turn |
If you already own Craftsman 917287242: what makes it cut “best”
Even a great tractor cuts poorly when the deck is out of level or the drive components are worn. These are the most common cut-quality contributors we see on riding mowers:
- Worn mandrel or deck hardware: can cause vibration and uneven cutting
- Worn blade-drive belt: can slip in heavy grass and reduce blade speed
- Dull or damaged blades: leave ragged tips and uneven discharge
If you are troubleshooting cut quality on this model, common related parts include the lawn tractor mandrel housing 587819701 and the husqvarna lawn tractor blade drive belt 584453101.
Why it matters
Choosing the right deck size prevents frustration: 42-inch decks reduce trimming and improve maneuverability, while larger decks reduce mowing time on open areas. Proper setup and timely belt and mandrel service usually make the biggest difference.
