Shear pins

In my experience it did get stuck only when it was dealing with deep snow. Driving forward. Finding too much of the snow. Slowing up and thinking it’s great idea to lift the blower a bit higher to get less snow that way to blow. Then not surprisingly it finds out that the snow it left is too deep for the core and can’t find enough traction. Then it reversed and that’s when it gets stuck. I don’t know why it thinks it’s ok to lift the snowblower even more. Maybe it would be good idea when it is set at 0 hight. It is however a stupid thing to do when I already have it at 2cm high. Core has anyway low clearance to begin with so there is not much room to play with.

When it makes the zero turns then the unit has already cleared the snow in that spot. I have never witnessed it to back up to some uncleared snowy area and then start to make its zero turn dance.

I think the low ground clearance is a design flaw. I understand the need for low ground clearance due to the wireless charging, but I think more ground clearance would have been better.

That said, it means it’s super critical to ensure the auger is as low as possible when clearing snow to avoid backing up (or zero turning) onto a mound of un-cleared snow.

Could you try increasing the auger height in that trouble spot to see if it helps?

It lifts the Blower because it thinks it has hit an edge on the ground so that is why the tracks slip. Then it lifts the snowblower so that it can get free. It shouldn’t keep doing that when it has lifted the snowblower an inch.

So, to follow up! Indeed, I found the cause! I’ve tried every possible angle, and there’s actually a tiny design flaw (but that’s just my opinion): the screws and threads of the screws on the four front bars shouldn’t be facing inwards from the outside, and the metal part should be facing outwards. Because the auger sometimes touches these screws and causes the pins to break ;-( This happens when there’s too much snow or heavy snow ;-( Unfortunately, I removed these four bars that prevent large objects from entering to see if it would solve the problem, and indeed, it completely solved it! Except that!!! I blew up my Auber gearbox because of a damn big rock that got stuck in the auger, and I think that with the multiple times it jammed, it finally cracked my Auber gearbox and made it release its last piece of rock ;-( So there you have it! I hope this will help solve this problem and put this part outside the blower!

take care everybody :wink:

I had already tried, but there was nothing on the ground and it never broke near me :wink: but read my post further down, I found the problem, unfortunately for me :wink:

Oh wow. I am so sorry to hear about your Yarbo’s premature demise!!

I haven’t heard of this happening before. You might be the first. Hopefully Yarbo (the company) takes care of you and gets you back in business soon. Please keep us in the loop.

Seems like using 8.8 grade bolts as shear pins is not a good idea…hitting a rock should shear the pins😬

Do most of you typically have extra shear pins on hand? Not to hijack the thread but anything else you recommend having as a better to have it and not need it than need it and not have it? I saw a thread in general talk about toolboxes for Yarbo but wondering if there is anything else snowblower related I should stock as backups?

My Yarbo snow blower history is very short. But I did purchase extra shear pins before the snow started flying. (Haven’t broken any yet. (Knock on wood.)

My previous experience with snow blowers says that at some point, a new scrapper bar will be needed. It’s not likely to just give up the ghost though I suspect it will wear over time.

I’ve seen one occurrence on the forums for the belt breaking. I haven’t bought one of those yet.

Other than that, I defer to those who have more experience with Yarbo snow blower.

As for the core, I keep extra antennas and antenna cables on hand. If you catch an antenna and break it off, it will likely take the cable connector with it. At least that is my experience.

Plowing a gravel driveway for a messy weekend of wet and freezing snow, I also went through a couple sets of sheer pins, which seem a bit to weak for the task at hand.

I’d definitely support changing the design to use standard size pins available everywhere for a fraction of the price.

I broke two sheer pins on my first time using the snowblower. Suffice it to say, I immediately ordered more.

Knock on wood, but I haven’t broke any pins since! Hopefully it stays that way.

That’s just a guarantee you won’t break any more. At least that’s my luck.

I had this happen, because the sides flex. When I tested the auger before the season, I could hear a tick tick tick sound each revolution. I then noticed it was hitting these screws. It didn’t break a pin but then again there was no snow yet. I bent the side a bit with a pliers and it seems to be ok, but I could see how this could be an issue longterm.

Are you referring to the screws that hold the “fence” on the front?

1 Like

yes, the bolts are rather “high profile”

I guess I never saw that issue as I removed the fence before the first snow.

Same here. I took that fence off as soon as I unboxed the snowblower in the summer!

I keep one bar only for safety, but maybe if I changed the bolts with low profile the problem will go away
