2305 with 47" 2 stage snowblower question

Thanks for the descriptive write-up. Since we cannot hear your blower, we'll have to assume you are correct and the noise level is more than normal. My 2210 has the same driveshaft arrangement, and I don't notice any more noise than on my old 425. Perhaps the bearings on the intermediate hitch are faulty. As I mentioned above and Shawk reconfirmed, more grease may help (I've never heard a pto failing from too much grease)

There aren't many zirks on the 47SB - seems there are a couple on the auger (so it'll spin free if you break a shear bolt) and that's about it.

Are there any by the chain or the short PTO knuckle?

Also - make sure you have a few shear bolts on hand. Never fails that you'll break one right after the JD dealer closes. Putting regular bolts in is a bad idea - bad things can happen in the gearbox. I've been told that there is a spot for a few of these to be stored right on the 47SB - anyone know where that is?

Hey Scott...Take a peak at these... Let me know if they don't come through clear enough. I didn't see anything regarding storage... I'd be interested as well though.

Look at the lower right in the first picture; see those 4 bolt heads lined up? Those are you spare shear bolts.

Hello

I have 2210 and 47" snowblower and this is my 2 year with it. I use it snow blow about 300 ft of sidewalks. The first year with only about 3 hours of uses the snowblower died! It ran very loud and I ask the dealer if this was ok. He said it's ok.

I was almost finished. It sounded like bomb went off. So I turned off the 2210. Looking at the snowblower the inter auger arm (the arm that holds the auger to the shaft) was broken. I need the snowblower, so installed parts myself. During the repair I notice that all the set screws for arm were loses. (No marks on the shaft from the set screws). I completely check the snowblower and found that it was not ready for uses. Nothing was right. Lose bolts, chain, etc. It's like the unit was put together for display. I put the new arm in. I tighten all bolts, chain, and used threadlocker for set screws for all arms. The unit is loud, but nothing like it was. I say it's about 50% less. So I would check unit complete before using it again. The only other thing I can think of is to make sure the PTO shaft is not rubbing up against the steering control rod.

Went back for a visit today,they now believe it is a bad driveshaft(the 4 foot long telescoping shaft from the mid-pto to the front). The shaft on the unit had quite a bit of run-out they said. They have a shaft on order to try now,seems most likely the cause. Thanks to all that responded,I will update later on with results.

Oh, that's no fun. You want me to actually READ my manual?

Thanks!

Okay Scott... There are 3 on the drive shaft... 2 on the knuckles and one in the center. Then you have two on the auger shaft... there how's that.

I just examined one of those shear bolts. Looks like as standard 1/4-20 grade 5 bolt.

I did a little research on the shear bolts simply because I usually go through several in a season. (On my walk behind snow blower, this is the first year for the Deere)

I checked the web page of Norm who makes the shear bolts on my 47 blower but had no luck.

I measured the Rockwell hardness and found it to be 25, slightly less than the hardness of other grade 5 bolts I had in my parts bins which measured Rockwell 31. Ungraded bolts ran around Rockwell 17. Grade 8 around R 36.

Norm did not show the three dash symbol on my bolt which is not the standard grade 5 layout which shows three dashes equally spaced around the bolt head. Instead they showed three dashes spaced off one side of the bolt. I finally found a picture of bolt gradings and it showed the Norm bolt as a grade 5.2

Third bolt down on this web page:

Hex Bolt Identification Guide - Engineers Edge

You will notice it is a low carbon steel bolt and not a medium carbon steel bolt all though the Tensile strength is the same.

My thinking is that a grade three to five bolt will work for this blower, I imagine much cheaper then Deere sells them for but I have not priced the bolts from my dealer.
