Pre season snow blower check

[CalG]

I was doing a pre-season look at the Kubota B2789 snow blower this afternoon.
One of the impeller blades was binding on the housing. Pessimistic me, was all in a worry about a bent shaft or impeller (4 blade)

I removed the discharge chute thinking to get a pry bar in. But even that top port didn't really give leverage access to the rubbing blade.

Then I got to looking hard at each blade gap to the housing. There was a stone lodged against the back side of the blade OPPOSITE of the blade that was rubbing. It took some real hammer blows on some sheet material used as a drift to get that stone to drop out.
Sure, that stone would have rubbed it's self away in short time, leaving a groove and damage until it did. Or, I would have made a mess of the impeller trying to bend the blade that wasn't at fault.

Sure made me glad to be a "what IS the real problem" kind of mechanic. And the discharge chute has never run more easily! ;-)

Let it SNOW!

Good find. I just did a checkup on my blower also, and greased / lubed the drivetrain.
It has sat for the last 5 years without use.

Good Morning CalG,

I was doing a pre-season look at the Kubota B2789 snow blower this afternoon.

Always a good idea to check out the equipment before the season starts ! Grease , oil change and filter along with general maintenance! Good catch !
