The PowerSmart auger blade assembly in this listing is stock number 303180424, the right hand flighting. There is a second right hand flighting in the same catalogue at a different price, and choosing between them is the whole job on this page. A powersmart auger blade assembly is the subject of this page, and the notes below are specific to it.

The case for this powersmart auger blade assembly
Our catalogue carries two right hand auger flighting assemblies: this one at stock 303180424 and another at 303180409. Both are right hand. They are not interchangeable.
Manufacturers run several housing widths and auger diameters off one product family, and the flighting changes with both. A wider housing needs a longer flighting, and a larger auger diameter needs a taller spiral. The PowerSmart auger blade assembly you need is decided by your specific machine, not by the brand name on the handlebar.
The price difference between the two reflects size and construction rather than quality. Neither is an upgrade on the other.

Choosing the right PowerSmart auger blade assembly
There is one reliable way to pick the correct PowerSmart auger blade assembly, and several unreliable ones that account for most wrong orders.
Reliable: take the old flighting off and measure it. Length along the shaft and outside diameter of the spiral are the two numbers that matter. Compare against the listing for each part number and order the match.
Also reliable: find your machine on the manufacturer parts diagram and read the stock number straight off it. The diagram is the authority.
Unreliable: matching on the photograph. Both parts look near identical in a listing image, because they are the same shape at different sizes with nothing in frame for scale.
Also unreliable: matching on the model name alone. Model codes mix series numbers, engine sizes and widths inconsistently between families, which is exactly how people end up with a PowerSmart auger blade assembly that is right handed and still will not fit.
| Method | Reliable |
|---|---|
| Measuring the old part | Yes |
| Manufacturer parts diagram | Yes |
| Comparing listing photographs | No, no scale reference |
| Matching on model name | No, codes are inconsistent |
Confirming the PowerSmart auger blade assembly side
Before choosing between the two part numbers, confirm the side. A two stage auger uses opposite hand spirals either side of the gearbox so that one direction of rotation feeds snow inward toward the impeller from both ends.
Stand behind the machine in the operating position: the right hand flighting is to your right of the gearbox. Parts diagrams are usually drawn from the front, which mirrors everything, so check the view before trusting a diagram on this point.
Fitted on the wrong side, a right hand flighting drives snow outward and packs it against the end plate. The machine runs, throws badly and jams repeatedly at one end.
Why a PowerSmart auger blade assembly usually outlives the machine
Steel flighting is not a wear part in the way rubber paddles or belts are. On most machines it is still serviceable when everything around it has been replaced twice, and understanding why helps you judge whether yours actually needs replacing.
The flighting never touches the ground. On a two stage machine the housing rides on adjustable skid shoes and the scraper bar takes the contact, holding the auger clear of the pavement by design. That is the whole reason two stage machines can work on gravel while single stage machines cannot.
It is also protected from impact. The flighting pins to the shaft through shear pins that are meant to break at a load well below what would bend steel. When the auger meets a buried kerb the pins go, the flighting stops, and everything expensive survives.
So a PowerSmart auger blade assembly that has genuinely failed has usually had that protection defeated: somebody fitted a bolt in place of a shear pin, and the next impact went straight into the flighting and the gearbox instead. Three things end one honestly: impact damage that has bent the spiral out of true, corrosion perforating the steel at the welds, and shear pin holes worn oval so the pin can no longer shear at its designed load.
Surface rust is not one of them. Flighting works in salted water for its whole life and looks it. Judge on shape and thickness, not colour.
Fitting the PowerSmart auger blade assembly
Power disconnected first. The flighting pins to the auger axle with shear pins, so drive the old pins out and slide the flighting off.
It will very likely be seized to the shaft. That joint sits in salted meltwater for its whole life, so allow penetrating oil real time to work rather than reaching for heat, which distorts flighting easily.
Clean the shaft and apply anti seize before the new part goes on. Fit genuine shear pins, then turn the auger a full revolution by hand and watch the flighting pass the housing at every point. It should sweep close without contact. Our snow blower shear pins explained piece explains why the pins matter, and Canadian Centre for Occupational Health and Safety covers de energising powered equipment before this kind of work.
Parts to order with a PowerSmart auger blade assembly
Two parts to have in front of you before committing to this one.
Auger Blade Assembly RIGHT: the other right hand flighting in the catalogue, and the one to compare against before ordering.
Auger Axle: inspect the shaft and its shear pin holes while the flighting is off.
Common questions
What is the difference between stock 303180424 and 303180409?
Both are right hand auger flighting, but they suit different housing widths and auger diameters. Measure your old part or read the stock number off the manufacturer parts diagram.
Can I tell them apart from the photographs?
No. They are the same shape at different sizes with nothing in frame for scale, so the listing images look near identical. Measure instead.
Is one PowerSmart auger blade assembly better quality than the other?
No. The price difference reflects size and construction, not quality. Neither is an upgrade on the other.
How do I confirm I need the right hand side?
Stand behind the machine in the operating position. The right hand flighting sits to your right of the gearbox. Parts diagrams are usually drawn from the front and mirror everything.
The flighting is seized to the shaft. What now?
Penetrating oil and patience. That joint lives in salted meltwater. Avoid heat if you can, because it distorts the flighting and then nothing lines up.
Should I fit anti seize on the shaft?
Yes. It is the one step that makes the next replacement possible without cutting the old part off.
