John Deere 1330se Snowthrower – Repairing a bent impeller blade

Today, I’m sharing a tale that’s a bit more embarrassing than usual, and it’s not just because of the snow.

Picture this: another beautiful winter day, but we have been slammed with snow so it is a perfect for building something with snow with my young kids. Armed with dreams of an icy snow ramp, I fire up my trusty snowblower and set out to conquer the snowy landscape.


But as it turns out, my snowblower had other plans. Spoiler alert: it decided to take an unexpected ‘snow day’ of its own.

So, grab a cup of hot cocoa and join me as I recount the frosty fiasco of how I managed to turn a simple snow project into a comedy of errors – and, of course, some unexpected DIY lessons learned along the way!


We’ve been having a brutal winter with lots of heavy snow so I figured I’d make some lemonade out of lemons by building a monstrous, 6 feet high snow tubing slope with 45 ft of runway for my kids.

Well, I was successful but at the cost of breaking my John Deere 1330 Snowthrower.

While piling up the snow, I apparently neglected to see a large rock and my snowblower decided to chew on it. Of course my snowblower lost, ending up with a bent rotor fin on my high-speed impeller.

The bent fin was actually sticking straight up, rubbing against my cowl and hitting my right auger every other turn, making 1330se useless (see good fins vs bad fin). So I:

  • tried to bend it back by hitting it with a hammer but I had an awkward angle so it did not work;
  • tried using my propane torch, thinking I can soften up the steel enough to bend it back the propane just could not make the steel hot enough;

With another snow storm approaching, I made a quick run to Home Depot and picked up a pseudo-acetylene torch kit as a last desperate attempt at fixing the bent impeller.

After spending 15 minutes to heat up the impeller fin (it was 10 below at the time), I was finally able to (somewhat) bend it back into original shape.

Heating Tip
Periodically stop while heating to see if you can bend the steel. The steel should be malleable when you start to see red flicks. DO NOT overheat the steel!

Although I ended up ruining the inside paint job (see the after-repair fin), I had my blower back (albeit with slight vibrations and the impeller belt jumping off, stopping the blower every 20 minutes or so).

When the snow season is over, I would like to take the 1330se apart and:

  • see if I can balance the impeller to make the vibration go away. Otherwise, I may have to replace it
  • make sure the impeller shaft is not bent
  • replace the shaft bearing since it probably got damaged

I will post a follow up article when I get it done.

There is a shear pin (bolt) behind gearbox on shaft in front of impeller.

My impeller on my JD 1330SE doesn't catch and turn. It will occasionally spin but has no power. The snow just clogs.... I can reach in... turned off... and just spin the impeller by hand.

I have changed the auger shear pins many times (I have a gravel driveway, and the occasional dog toy left out before a snow... Is there a shear pin for the impeller?

There is one lug that crimps on the shaft. there aren't any shear pins.

Ironically, my JD snowthrower broke during last snow storm (exactly the same problem as yours). I will need to tear it down..

Thx with your detailed info. I find my local JD dealership less than useful. Can't even get parts. Thx again.
