PowerSmart Lawn Garden Buying Guide — Part 5: Models and Features Compared

Start here: how to confirm the exact PowerSmart part

PowerSmart uses Stock#/SKU identifiers in each model’s parts diagram. To get the right item on the first try:

• Find your equipment’s model number decal, then open the parts list/exploded view in the manual.
• Copy the exact Stock#/SKU from the diagram (example format: 303xxxxx, T65.xxxx, E65.xxxx).
• Match that number to the product listing. If your manual calls out a side (left/right), a width (21/22/24 in.), or an engine family (161cc/170cc/209cc), verify those details.
• If your original is damaged beyond recognition, compare photos and drawing callouts in the manual before ordering.

Snow blowers: auger drive and chute control parts compared

These are the high‑impact replacements shoppers ask about most often on two‑stage machines.

• Worm GearBox Right, Stock#303090031: Right‑hand worm gear case used on many 24–28 in. two‑stage units. There is a distinct left‑hand case (different Stock#) — do not mix sides; order the side your manual specifies.
• Auger Axle, Stock#303160370: Called out for multiple 24 in. models. Some manuals list different 24 in. axle Stock#s for revisions; use the exact number from your model’s diagram to avoid length/shoulder mismatches.
• Chute Deflector Cable for HB7108A/DB7108B/PSSAM24, Stock#303200151: Fits the listed models per the manufacturer. Confirm your chute style (crank vs lever) so the sheath length and end fittings match. After install, verify full up/down deflection without kinks and set tension with the deflector fully closed.

Lawn mowers: cutting system and bag hardware

Blade hubs, springs, and bag brackets vary by deck family. Cross‑check your model’s diagram before you buy.

• Blade Connector, Stock#303181407: Blade‑to‑crank hub shown in several 21 in. mower diagrams (e.g., DB2194PH/PSM2521PH families). Some models use a different connector (e.g., 303180808); order the Stock# your manual lists.
• Mower Blade, Stock#30400275: Replacement blade used on select PowerSmart decks. Match by deck size and Stock# in your parts list.
• Torsional Spring for DB8621SH/DB2194SH, Stock#303130379: Side‑discharge door return spring for DB8621/PSM2521‑series layouts. Don’t confuse it with rear cover or bail springs that use different Stock#s.
• Collector Holder V8622S, Stock#303181599: Grass‑bag holder bracket specific to V8622S/B8622S layouts; it’s not a universal 22 in. bracket.

Engine service parts: 161cc vs 209cc

PowerSmart engine families use different SKUs. Mixing them leads to poor fit or performance.

• 161cc Spark Plug, Stock#E65.2160.001.00.00: Listed for 161cc mower engines in multiple exploded views. Do not substitute 170cc-family plugs.
• 161cc Air Filter Assembly, Stock#T65.2280.001.00.00 vs Air Filter Cover, Stock#T65.2280.001.00.01: Choose the full square‑style assembly if the housing or element stack is damaged; choose the cover‑only when the base and element are fine. The cover page lists fit models including DB2194P and DB8621P.
• Fuel Tube Clamp, Stock#90685-1000-01: Specified fuel hose clamp in several 161cc/170cc engine schematics; use to secure the line at the tank and carb nipples.
• 209cc Recoil Starter Assembly, Stock#9528960901: For PowerSmart 209cc engines. Verify your engine family in the manual’s engine schematic before ordering.

String trimmers: guard, head spring, and line length

Handheld and walk‑behind trimmers use different consumables and guards.

• Trimmer Line 470mm for DB6222, Stock#306040043: Precut line segments for the 22 in. walk‑behind trimmer DB6222. Each piece is 470 mm (~18.5 in). The DB6222 product page lists ~0.16 in (~4.0 mm) line diameter.
• Safety Guard for PS4532/AM4532, Stock#BG430.2.6: Replacement guard called out in the PS4532 guard assembly. Use the correct guard to maintain the cut‑off knife function and line length control.
• Trimmer Head Spring for PS4531/PS4532/AM4532, Stock#PS4532-J-002: Replacement compression spring for the PS453x/AM4532 nylon head. Match the Stock# from your head assembly diagram.

Fit‑check checklist (before you add to cart)

• Confirm model and serial on your machine’s data label; open the parts list/exploded view for that exact model revision.
• Match the Stock#/SKU from the diagram to the listing (examples in this guide use formats like 303xxxxx, E65.xxxx, T65.xxxx).
• For snow blowers, order by side (left/right) and auger width (e.g., Worm GearBox Right, Stock#303090031, Auger Axle, Stock#303160370). Left and right gear‑case halves are not interchangeable.
• For mowers, verify deck family and hardware style (e.g., Blade Connector, Stock#303181407, Torsional Spring, Stock#303130379, Collector Holder, Stock#303181599).
• For engines, confirm 161cc vs 170cc vs 209cc before ordering parts like Spark Plug E65.2160.001.00.00, Air Filter Assembly T65.2280.001.00.00, or 209cc Recoil Starter 9528960901.

FAQs from shoppers (answered briefly)

• How do I tell if Worm GearBox Right, Stock#303090031 fits my unit? Check your snow blower’s exploded view: it will label right‑hand vs left‑hand cases by Stock#. Order the side your diagram lists.
• What’s different about Auger Axle, Stock#303160370 vs other 24 in. axles? Small changes in length, shoulders, or hole placement can exist across revisions. Use the exact Stock# from your model’s list to avoid misfit.
• Does Chute Deflector Cable, Stock#303200151 fit my machine? The manufacturer lists HB7108A, DB7108B, and PSSAM24. If you have a different chute style or model, match your cable’s Stock# in the manual.
• My blade hub is stripped—do I need Blade Connector, Stock#303181407? Many 21 in. decks use it, but some families moved to a different connector. Check your deck’s parts page for the exact Stock#.
• Do I need the full 161cc Air Filter Assembly or just the Cover? Replace the full assembly when the housing/element stack is damaged or missing; replace the cover when only the cap is broken.
• What torque should I use when reinstalling the blade with Blade Connector, Stock#303181407? Use the blade bolt torque specified in your model’s manual. Block the blade with wood, install with the cutting edge oriented correctly, and re‑check torque after first use.
