For Craftsman model 917274961, the owner’s manual identifies it as a 21.0 HP garden tractor with electric start and a 46-inch mower deck. For the exact engine make, model, and spec numbers, match the engine ID label on your engine to the listings in the 917274961 owner's manual.

How to identify the exact engine on your tractor

We use the engine’s ID tag to pinpoint the correct engine family and service parts (filters, spark plug, fuel parts), because horsepower alone is not enough.

• Park on a level surface, set the parking brake, and remove the key
• Let the engine and muffler cool completely
• Lift the hood and locate the engine ID label (often on the blower housing, valve cover, or near the starter)
• Write down the engine model, type, and code (or spec number)
• Use those numbers when ordering tune-up parts or looking up engine-specific procedures

What the manual confirms for model 917274961

The manual for this specific model calls out the tractor configuration and controls used to operate the engine and deck.

Item	What you can expect on 917274961	Why it matters

For a Craftsman lawn tractor like model 917274961, a full engine replacement typically costs $260 to $1,800 installed, with labor commonly running around 6 hours for a riding mower. Your total depends on the engine price, any wiring or belt parts needed, and shop labor rates.

What drives the total cost

Engine replacement is more than just the engine itself. Plan for these common cost factors:

• Engine price (largest variable; depends on horsepower, shaft size, and charging system)
• Labor time (riding tractors commonly take longer due to hood, wiring, and linkage removal)
• Extra parts you may replace “while you’re in there” (belts, pulleys, hardware)
• Fuel system cleanup if old fuel or debris contributed to the failure
• Electrical/safety interlock checks after installation (seat switch, brake switch, PTO switch)

Typical cost ranges (what most customers see)

These ranges help you budget before you price the exact engine for your tractor.

Cost item	Typical range	Notes
Engine (part only)	$200 to $1,400	Varies by brand/spec and availability
Labor (shop)	$300 to $900	Often based on ~6 hours plus shop rate
Misc. parts/fluids	$20 to $200	Fuel line items, clamps, oil, filters, hardware
Estimated total installed	$260 to $1,800	Matches common industry pricing

Parts you may end up replacing during an engine swap

We often see these related items replaced to prevent repeat issues and reduce downtime:

• Riding lawn mower blade drive belt 532148763 (if the belt is cracked, glazed, or oil-soaked)
• Switch.pto 582107601 (if the PTO circuit is intermittent after reassembly)
• Molded ignition key 532140403 (if the key is worn and causes unreliable starting)
• Lawn tractor ignition harness 532170238 (if wiring is brittle, corroded, or damaged)

Why it matters

A correct engine match and clean installation prevents hard-starting, charging problems, and unsafe operation. Your tractor’s safety system is designed so the engine should not start unless the brake is fully depressed and the PTO is disengaged; after an engine swap, verifying those interlocks protects you and the machine.

Where to confirm specs for your exact tractor

Use the 917274961 owner's manual to confirm the correct engine specifications, safety interlock operation, and service procedures before ordering parts or scheduling labor. For parts shopping beyond the list for this model, search by model number on Sears PartsDirect.

Yes; replacing the engine on your Craftsman lawn tractor model 917274961 is worth it when the deck, steering, and drive system are in good shape and the total swap cost stays well below the cost of replacing the whole tractor. If several major systems are worn, replacement is the better value.

Quick decision checklist

Use these checks before committing to an engine swap:

• Deck shell has no rust-through or cracks
• Blades engage and the deck spins freely (no seized mandrels)
• Drive system moves consistently (no chronic slipping or loss of drive)
• Wiring and safety interlocks work reliably
• You can get the wear parts you need for a complete refresh

For model-specific safety and service procedures, follow the 917274961 owner's manual.

Cost vs. condition: a simple guide

If this is true	Engine swap is usually	Why
Tractor is structurally solid; engine is the main failure	Worth it	You restore reliability without replacing the whole machine
Deck and drive need minor service only	Worth it	Common wear items are manageable alongside the engine
Deck is failing and drive/steering also need major work	Not worth it	Costs stack quickly and downtime increases

Parts that often go with a deck-related repair

If the engine is fine but the deck will not spin or cuts poorly, these common wear items can be part of the fix:

• Riding lawn mower blade drive belt 532148763 (belt wear, glazing, stretching)
• Idler and mandrel components (binding or noise)
• Blades and deck cleaning (grass buildup increases load)

Why it matters

Many “bad engine” symptoms come from fuel, spark, airflow, or excessive deck load. The troubleshooting steps in the manual help you rule out lower-cost fixes before you invest in an engine.
