Question Leaves trail on clean side

Hi All, New member with a question. I have a 28" Troy-bilt and it's on it's 4th season. We just had a 16-18" snow storm. And after making the initial cut down the middle of the driveway, the next cuts I can only take about a 6" cut, and even after that it leaves a trail of snow 3-4" tall on the clean side that I have to clean up with an additional pass. The depth doesn't have a lot to do with it because this also happens with as little aas 4" to 6" storm. After reading through some threads, I have verified the augers are correct, and the skid plate and shoes are adjusted right. Any other thoughts? I'd attach a pic of the augers but don't see where to do it.

Welcome!

I've had 3 blowers, I know I've had this issue on 2 of them at times, and I think on the third as well.

(Edit- sorry, this was confusing. I mean they will sometimes leave some snow on the clean side. But that's with taking either a full-width cut, or close to full width. Not using just 6" of a 28" machine)

Check the easy stuff, make sure all your shear pins are intact. With the engine off, you should be unable to rotate the auger sections on the shaft.

If that checks out, then I think it has to do with your ground speed, and how fast the blower can process the snow.

Sometimes I have to slow down, or take narrower cuts, to avoid snow overflowing onto the area I've already cleared.

Other times, I'll go at a quicker ground speed, allowing it to leave an overflowed trail of snow. Then I'll make a last set of passes in top gear, quickly going up & down the driveway to clear off the overflow trails. Sometimes this method is actually quicker, since 6th gear on my machine is pretty quick, and it lets me also clear faster during the first passes. It can also help get down to bare pavement, since the second pass gives it another chance to scrape lower.

Can someone operate the machine while you watch the augers & bucket? Maybe that would help show something.

Have you verified that both augers are rotating?

Yes they are both rotating, no sheared pins.
Another point, all this is at lowest forward speed (1).

I would have someone in front of the machine looking at to see if both augers are turning at the same speed.

Check to see if both augers are turning at same speed while under load (blowing snow). If they are not then you have a broken shear pin. I had that problem when one of the shear pins was broke but did not dislodge from auger. As a result both augers would turn when clear. But under load the auger with the broken shear pin did not turn.

Appears they both turn under load.

Something is wrong if you can only be effective using 6 of 28 inches. I may drop to 2/3s of a bite to avoid spillover but like others will usually opt for a nearly full bite and a clean-up pass.

I had the first reaction of a slipping auger but you have confirmed that's OK over and again.

Do you get the same situation working either side? Are you running the engine at full throttle?

Leaving a small windrow is common on newer machines where the augers are set back from the front of the bucket. Augers extending out in front of the bucket are cutting and pulling the snow inward before reaching the bucket edge which provides a neater once only clearing pass.

I would suspect a slower than designed auger/impeller speed due to a slipping/misadjusted belt in the OP's case.

i would check the impeller/blower to see if there is any play ( bearing ) and also check the belt for slipping.
