Poulan 917447620 gas lawn mower Parts

If your Poulan 917447620 gas lawn mower needs a major repair that costs more than about half the price of a comparable new mower, replacing the mower is usually the cheaper long-term choice. For smaller fixes (blade, cables, wheels, hardware), repairing is typically the better value.

A practical rule we use

• Repair it when the issue is a wear item or a simple adjustment (blade, control cable, height adjuster, wheel parts).
• Replace it when the repair is a major drivetrain or engine-level cost, or when multiple big issues stack up.
• Decide fast if the deck is rusted through or the mower has structural damage; those repairs rarely pay off.

Common repairs that are usually worth it

These are typical on walk-behind mowers and often restore performance quickly:

• Replace a dull or bent blade such as the lawn mower 22-in deck 3-in-1 blade 532420463
• Replace a stretched or broken operator cable such as the lawn mower zone control cable 532420939
• Fix self-propel problems caused by a worn cable such as the lawn mower drive control cable 532420562
• Replace damaged height hardware such as the husqvarna lawn mower height adjuster knob 532701037
• Replace worn wheel components such as the craftsman lawn mower drive wheel 581009202

Repairs that often push you toward replacement

Major repairs can approach the cost of a new mower, especially when labor and multiple parts are involved:

• Engine replacement or internal engine repair (low compression, heavy smoking, severe knocking)
• Transmission replacement (for self-propel models) such as a full lawn mower transmission assembly 589600601
• Deck replacement or extensive deck rust-through

Quick cost comparison

Situation	Typical best choice	Why
One worn part (blade, cable, wheel)	Repair	Low parts cost, fast turnaround
Self-propel slips but engine runs strong	Repair first	Often cable, wheel, or transmission wear
Engine has major internal damage	Replace	High parts and labor cost
Multiple major issues at once	Replace	Costs add up quickly

Why it matters

A walk-behind mower like the Poulan 917447620 is designed for routine maintenance and common wear-part replacement. Putting money into the right repair keeps cut quality and safety high, while avoiding oversized repairs prevents sinking money into a mower that will still be unreliable.

The most common repairs on a Poulan gas walk-behind mower like model 917447620 involve basic tune-up and drive or cutting issues: getting the engine to start and run smoothly, restoring cutting performance, and fixing self-propel problems. Many fixes come down to routine maintenance plus replacing a worn blade, cable, or drive parts.

Most common repairs we see

• No-start or hard-start: old fuel, dirty carburetor passages, fouled spark plug, clogged air filter
• Runs rough or surges: restricted fuel flow, dirty carburetor, air leak, partially clogged filter
• Loss of power under load: dull blade, heavy/wet grass, dirty air filter, fuel restriction
• Poor cut quality: bent or dull blade, deck packed with grass, incorrect cutting height
• Self-propel not working or weak: stretched/broken drive cable, worn belt, transmission or drive wheel wear

Quick checks before you buy parts

1. Drain old fuel and refill with fresh fuel (use the correct oil level as well).
2. Inspect and clean the underside of the deck (built-up grass reduces lift and power).
3. Check the blade for damage and sharpness; replace if bent or badly nicked.
4. Verify the control cables move freely and fully engage when you squeeze the handle.

Parts that commonly solve these problems (model 917447620)

If your symptoms point to a worn cutting or control component, these model-matched parts are common fixes:

Symptom	Likely area	Example part for this model
Ragged cut, vibration	Blade	Lawn mower 22-in deck 3-in-1 blade 532420463
Blade will not stay tight	Blade mounting hardware	Husqvarna lawn mower lock nut, 3/8-in 532409149
Engine stops when releasing handle or won’t stay engaged	Operator presence/zone control	Lawn mower zone control cable 532420939
Self-propel won’t pull	Drive control	Lawn mower drive control cable 532420562
Weak or no drive	Transmission/drive	Lawn mower transmission assembly 589600601

Why it matters

Catching small issues early (dull blade, dragging cable, loose hardware) prevents bigger failures like damaged crankshafts, stripped fasteners, and premature transmission wear. It also improves cut quality and reduces engine strain.

Poulan Pro lawn mowers are made under the Poulan brand family, which is part of Husqvarna’s outdoor power equipment group. For your Poulan walk-behind mower model 917447620, that means many replacement items and hardware cross over with Husqvarna-style mower parts.

What this means for parts and compatibility
