Craftsman 917377553 rotary lawn mower Parts

Common problems on the Craftsman rotary lawn mower model 917377553 include no-start conditions (old fuel, dirty air filter, fouled spark plug, fuel restriction), loss of power from heavy grass or deck buildup, excessive vibration from a worn or loose blade, and self-propel issues from a worn drive belt or drive control. Use the 917377553 owner's manual troubleshooting chart to match symptoms to the most likely cause.

Most common symptoms and what usually causes them

• Won’t start: stale gas, dirty air filter, spark plug issue, fuel not reaching the carburetor
• Starts then dies or surges: restricted fuel flow, dirty carburetor passages, contaminated fuel
• Loss of power: cutting too much grass, deck packed with clippings, dirty air filter
• Poor cut or uneven cut: blade worn or bent, deck buildup, wheel heights set uneven
• Excessive vibration: blade loose/bent, blade adapter damage
• Starter rope hard to pull: blade dragging in grass, brake not releasing, possible crankshaft or adapter issue

Quick checks we recommend first (fast, no parts guessing)

1. Fuel: Drain old fuel and refill with fresh gasoline if it has been sitting.
2. Airflow: Clean or replace the air filter; restricted airflow is a top cause of power loss.
3. Spark: Inspect the spark plug and boot connection; replace the plug if fouled.
4. Deck condition: Tip the mower safely and remove packed grass from under the deck.
5. Blade and hardware: Check for a loose blade bolt, bent blade, or damaged adapter.

Parts that commonly solve the problem (when symptoms match)

Symptom	Common wear item	Example part for 917377553
Self-propel won’t move or slips	Drive belt	Belt 532157769
Vibration, poor cut	Blade or adapter wear	Lawn mower mulching blade 532406713 and lawn mower blade adapter 581547901
General seasonal performance drop	Tune-up items	Briggs & statton tune-up kit 5140B

Why it matters

Running with a loose or bent blade can damage the blade adapter, crankshaft, and deck. Keeping the underside of the deck clean and staying on top of tune-up items helps the mower cut cleaner, start easier, and last longer.

A Craftsman 54-inch deck mower belt size depends on the exact tractor model and deck configuration; it is not the same as the belt used on the Craftsman 917377553 walk-behind mower. For model 917377553, the drive belt is listed as a V-belt in the parts breakdown; confirm the correct belt by matching your model and part listing in the owner's manual.

What we can confirm for Craftsman 917377553 (walk-behind mower)

This model is a 22-inch rear-discharge rotary lawn mower, and its drive system uses a V-belt (not a 54-inch deck belt).

• Model: Craftsman 917377553 (22-inch walk-behind)
• Belt type shown in the parts list: V-belt (drive belt)
• Common related drive parts you may also inspect:
  • Belt 532157769 (drive belt kit)
  • Drive control and linkage (cable, control assembly)
  • Pulleys and belt guides

If you actually have a 54-inch deck mower

A “54-inch deck” typically refers to a riding mower or lawn tractor deck belt. The correct belt is chosen by:

• The tractor model number (from the frame tag)
• The deck model or deck part number (if separate)
• Whether it is a deck belt (blade drive) or a transmission belt (ground drive)
• Idler pulley and routing style (varies by deck)

Quick comparison

Mower type	Typical belt you are asking about	How to identify it
54-inch deck rider	Deck (blade) belt	Tractor model plus deck size and routing
Craftsman 917377553 walk-behind	Drive V-belt	Walk-behind model parts list and belt routing

Why it matters

Using the wrong belt length or profile can cause slipping, poor self-propelled performance, thrown belts, or premature pulley and bearing wear.

Ordering the right belt

For Craftsman 917377553, we recommend ordering by the exact part listing for your model, such as the belt 532157769. For a 54-inch deck rider, search by the tractor model number on the parts list for that machine, or use Sears PartsDirect to look up the correct deck belt by model.
