The short rubber blade is the smaller of the paired lengths in a PowerSmart single stage auger set, stock number 302110091. Buying one is straightforward. Knowing whether you should be buying one or four is the part worth reading about. This listing is a short rubber blade, and everything below is written about that specific configuration.

Where a short rubber blade fits
A single stage auger is not fitted with four identical rubber paddles. It carries blades of different lengths arranged along the spiral, so that the snow is swept progressively toward the centre of the housing and up into the chute rather than all at once.
The short rubber blade is one element of that arrangement. Because the lengths are not interchangeable, the position each one occupies is fixed by the parts diagram for your model, and fitting a long blade where a short one belongs will foul the housing. Photograph the auger before you dismantle anything. That single habit prevents the most common reassembly mistake on this job.

Why the set beats one short rubber blade
Here is the arithmetic nobody does before ordering. Every blade on the auger has run the same hours, over the same surface, against the same grit. They do not wear at identical rates, but they wear on the same schedule.
Replace one short rubber blade and you have a new blade reaching the ground alongside three that no longer do. The new one now carries a disproportionate share of the load and the ground contact, so it wears faster than the one you replaced did, and the machine still under performs because three quarters of the auger is still short. You will be back for the others inside a season, paying shipping a second time.
| Approach | Up front | Result |
|---|---|---|
| Replace one worn blade | Lowest | Machine still under performs, uneven load, second order later |
| Replace the full set | Higher | Full throw and traction restored, blades wear evenly |
The exception is real: if one blade has been torn by a buried object while the rest are still good, replace the one. Damage is not the same as wear.
Measuring short rubber blade wear properly
Most owners eyeball the rubber and guess. There is a better test, and it takes a minute.
With the power disconnected, rotate the auger by hand until the short rubber blade is at the bottom of its travel. Sight along the bottom edge of the housing. A serviceable blade reaches the ground line. Measure the gap if there is one: more than about three millimetres and the machine is skimming rather than clearing, and its self propulsion has largely gone.
Then compare that gap across all the blades in the set. If they differ by more than a millimetre or two, the auger is running out of true and you should check the shaft and bearings before you spend money on rubber. Our snow blower repair guide covers that inspection, and the general seasonal checks are in the maintenance checklist.
Fitting the short rubber blade
Disconnect the power source before anything else: plug lead off, cord unplugged, battery out. An auger holds stored energy and can rotate as a jam releases, which is exactly how hands get hurt. Our snow blower safety guide covers the wider habits, and Canadian Centre for Occupational Health and Safety publishes the general guidance on de energising powered equipment before service.
Tip the machine onto its housing. Free the bolts holding the blade and its steel backing strip, expecting salt seizure. Fit the short rubber blade in the same orientation and position it came out of, with the backing strip on the original side. Tighten progressively from the centre outward so the rubber beds flat rather than pinching at one end.
Turn the auger a full revolution by hand before restoring power, listening for contact with the housing. It should sweep close without binding.
Ordering the right short rubber blade first time
Order by stock number. The short rubber blade, the small blade and the standard blade are different part numbers and photograph almost identically, which is how people end up with a part that does not fit and a machine in pieces during a storm.
Order early too. Wear parts sell out in December and January across the whole country at once, because everyone discovers the same problem during the same storm. Buying the set in October costs the same as buying it in January and is far more likely to be in stock. The seasonal pattern is covered in our snow blower price guide, and the full range is in parts and accessories.
Related parts on the same machine
If you are ordering the set rather than the single blade, these are the two items most often bought with it.
Long Rubber Blade (Curved): the curved blade in the same set, and the one that must go back the right way round.
21 inch Shave Plate: the scraper bar under the housing, which wears against the same surface as the blades.
Common questions
Is the short rubber blade the same as the small rubber blade?
No. They are separate stock numbers in the same auger set and they are not interchangeable. Order by number rather than by the photograph.
How many short blades does my auger need?
It depends on the model. Check the parts diagram, or photograph your auger before dismantling it and count them. Machines in the same family can use different arrangements.
Should I buy the whole set?
Usually yes. All the blades have run the same hours over the same surface, so replacing one leaves you with a new blade doing the work of four and another order to place within weeks.
What if only one blade is damaged?
Then replace the one. A blade torn by a buried object is damage, not wear, and the rest of the set may have plenty of life left.
How much of a gap is too much?
More than roughly three millimetres between the blade tip and the ground and you have lost most of the throw and most of the self propulsion. At the point where the steel backing strip shows, stop using the machine.
Do the blades need to be a matched set from the same batch?
Not from the same batch, but they should be at similar wear levels. Mixing a new blade with heavily worn ones puts the auger out of balance and you feel it through the handlebar.
Can I trim a longer blade to fit?
No. The lengths are matched to positions on the spiral and the moulded profile is not uniform, so a trimmed blade will not seat or sweep correctly.
