Verdict: Choose the auger side parts if the gathering stage needs spares: shear pins that give way under strain and a clutch cable that engages the auger. Choose the impeller side kit if the throwing stage clogs and the gap between blade and chute needs narrowing.
A driveway after a storm sets the job: snow piled where the cars go, packed where tires crossed it, and a machine that has to move it without clogging. The auger vs impeller snow blower question is about the stages inside a snow clearing machine, and this comparison looks at them through parts listings for each side, so the mechanism choice comes before any single part.

Figures are as stated in the listings, collected 2 November 2026.
How the auger side works
The auger is the gathering stage: it meets the snow first, gathers the snow and feeds it onward. The shear pin kit exists because that meeting can go wrong: when the auger hits excessive resistance from packed snow, ice or debris, the pin shears instead of passing the full stress into the auger drive components. The auger cable is the other half of the side: a clutch cable that engages the auger, with a Z bend on one end and a spring on the other.
How the impeller side works
The impeller is the throwing stage: it takes the snow the auger feeds it and throws it out through the discharge chute. The impeller kits here are modifications, not machines: rubber paddles and metal straps that narrow the gap between the blade and the chute, so the machine clogs less after working a while. Both kits use 1/4 inch thick rubber paddles and grade 5 steel hardware, and both are described as universal for 2-stage machines.
Parts, not whole machines
All four listings here are parts, and the comparison is honest about that. No listing here is a complete snow blower, so no side wins on clearing width, throwing distance or engine size: none of those specs is stated for a whole machine in these listings. What can be compared is the job each part does, what it is made of, and what it fits.

Matching It to Your Property
- Match part numbers before ordering: the shear pin kit replaces 738-04124 and 714-04040, and the cable replaces 946-0897.
- Keep spare shear pins on hand: the kit provides 10 matched sets for compatible machines.
- Check cable length against the old cable: 47.3 inches of cable and 40 inches of conduit, with a Z bend rod adjustable from 4.8 to 6.7 inches.
- Impeller kits fit 2-stage machines; check the blade count the kit covers, 3 blades or 4 blades.
The Acre Score explained
The Acre Score weighs performance, build, value, safety and warranty, using only what each listing publishes. For these parts, safety means a stated protective function, like a shear pin designed to break before the auger drive does; only the shear pin kit states one, so only it scores for safety. No listing states a warranty term: the 3-blade impeller kit states a 30-day money-back policy, which is not a warranty, so every warranty score is zero.
| Product | Acre Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| Wilsnsun Shear Pin Kit | 9.6 | 29 | 21 | 21 | 7 | 0 |
| Huthbrother 3-Blade | 9.4 | 28 | 20 | 21 | 0 | 0 |
| Huthbrother 4-Blade | 9.4 | 28 | 20 | 20 | 0 | 0 |
| Quanaoo Auger Cable | 9.4 | 28 | 20 | 19 | 0 | 0 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.
Many owners keep spares for both stages: shear pins and a cable for the gathering stage, and an impeller kit for the throwing stage. If the machine itself needs work beyond these parts, see our mower maintenance guides.
Read the manual, keep children and pets out of the yard while you work, wear eye and hearing protection and sturdy footwear, and never exceed the slope rating of your machine. Refuel only with the engine off and cool. See CPSC lawn mower safety. Read our Safety Disclaimer.
FAQ: mowing large lots
What does an auger shear pin do?
It breaks on purpose. When the auger meets excessive resistance from packed snow, ice or debris, the pin shears so less stress reaches the auger drive components.
What does an impeller kit change?
It narrows the gap between the blade and the snow discharge chute. Both kits are designed to minimize that gap to reduce the chance of clogging after working a while.
Do these parts fit any 2-stage snow blower?
No. The impeller kits are described as universal for 2-stage machines, but the shear pins and the cable fit only the models their listings name, so match part numbers before ordering.
Which side needs more upkeep?
The auger side listings are spares and replacements: 10 matched shear pin sets and a replacement cable. The impeller side listings are modification kits installed on the machine.
Can an impeller kit stop all clogging?
No listing promises that. The kits are designed to reduce the chance of clogging after working a while, not to end it.
