Newly purchased and professionally installed blower consistently throws belt. Throws off main drive after running for two minutes. As you can see on video, due to the angle of the belt it is being forced off the main drive. Trying to get back to dealer but looking for suggestions.

Welcome to GTT!

Do you not have any belt gaurds/guides near the engine sheave?

No I don't. It was dealer installed but there are not any guards on the main drive pulley. There are guides on the two smaller pulleys. I believe they are called shieves.
Should the blower have come with a belt guide on the main drive?

I'm not an expert on these machines by any means, but I did some poking around in JDParts.com and found this. It's the front implement drive for a 2015 x300 (SAB10022)

Does yours look like this?

From your video it looks like the engine drives a belt directly to the blower. This diagram shows a jack-shaft and a shorter belt. This has another pulley/sheave that drives your snowblower. See the two belts? one is dramatically shorter than the one that goes to the blower.

Again, I'm not familiar with your machine and I could be looking up the wrong stuff on JDParts. Your dealer should be involved so they can correct the issue.

Understood
There is only one belt that drives the blower. It is driven by the main pulley off the engine. That is the same pulley that the belt keeps coming off. I agree that it needs a belt guide to keep it on that pulley when the angle of the belt changes.

I also have a JD 44 blower on my 2013 X310. I have had lots of problems with the belt on mine to. Mine doesn't throw the belt off, but the belt wears out prematurely like in about 10 hours of use. JD is having problems with this blower and my local dealer gave me about 5 pages of "Tips" from JD to possibly fix the problem. I don't have them with me now as my manual is at my hobby farm. I kind of fixed mine by bending the bracket that holds one of sheave pulleys so it better lines up with the drive pulley on the engine. Looking at your video, it seems that when you drop the blower, it is at too much of an angle. Have you checked that the blower is mounted correctly. I don't think mine runs at that much of an angle when the blower is lowered. Since your unit is new and installed by the dealer, I would go back to them and see if they can correct it. Also, ask your dealer to make a copy of the newsletter tips JD send out to their dealers last year. I would also be interested in what your dealer has to say. Also, I can maybe scan these documents if you can't get them. Let me know. Al

Thanks Al,

I took it back to the dealer and they offered great service. They looked at it and attempted repair the same day. They came to a similar conclusion re the plate that holds one of the pulleys requiring a bend to better line up with the drive shaft pulley. I brought it home and used it for 10 minutes before the belt came off again. The dealer is investigating for me now. I trust they will come up with a solution. I wonder if the blower unit I have is faulty and needs to be replaced? Or maybe it needs to be taken off and re installed with a new belt at a better angle? My concern is that its gets fixed temporarily an then I am stuck in the middle of a snowstorm after 10 hours or less.

I realize you spent your hard earned money on this setup. After years of problems with belt driven blowers. I dug deep and bit the bullet and went to pto drive blowers. No more belt driven blowers for me. I'm not much help with your situation, but in my area when the snow needs to be be removed it's gotta work

I can't believe Deere would expect that belt to run at an angle that extreme. The jack shaft diagram looks ideal to solve the issue, although costly with the extra parts required. Could they maybe add a bell shaped pulley to the drive end that would lower the sheave?

The dealer has been great. They came to pick it up today and will try to repair again. This time they will have the time to give it a good test before they return it to me. Yesterday we were against the clock with a big snow storm coming.
I think it does require some sort of a belt guide to keep the belt on.

There should be a product improvement program on this setup that requires a plate and different idlers to better align the pulleys off the engine so that it quits jumping off. A guy I work with did one the other day to correct this problem your local Deere dealership should be able to find that pip for you

Thanks for the valuable information

Of course, the temps here in deep South Jersey are more like April than December, but I was thinking about a front-mounted blower for my 2012 X310 rather than a PTO model on my 1026R. The smaller tractor would be more useful doing the five driveways (two with L- shaped parking areas and a couple of nooks and crannies) at my home and rental property across the street. There is also a shrink-wrapped boat to negotiate. But after reading this thread, I would have some doubts...
I had a nice little L176 with a 38" blower that was PERFECT for the job, but I sold it when I bought the two new ones. Talk about regret!
Well...maybe it will be an early spring.

Tim,

The document I got from my JD dealer last year was titled "//dtac.deere.com/Solutions/English/75064.htm" published Feb. 20, 2014. It is labeled "Solution Number 75064". Solution Summary States: "Belt Jumps Off On 44-in or 47-in Snow Blowers- X3/X5 Select Series".

The solution says order "1 M154563" Belt Guide, "1 M78494" spacer, and "1 03M7095" Cap Screw. Install per 75064 1.jpg photo. Basiclly the photo shows adding a 2nd spacer on the left hand sheave pulley. The cap screw just replaces the original sheave pulley cap screw as it is about a 1/2 inch longer. I think my dealer gave the extra spacer and cap screw last year. If your dealer can't print a copy of this "DTAC", let me know and I can scan or mail you a copy of mine.

The belt guide listed above may all ready be on your blower if it was built in the last couple of years. Mine had it. It is the guide that is attached to left hand side of blower to keep the belt on the large gear box pulley.

I ran my blower about 3 hours this morning trying to move a 3 ft. drift on my hobby farm. I checked the belt several times and didn't notice any belt shredding like last year. And this belt was one that I turned around after I did the suggested fix on the idler pulley. I think this is the longest time I have seen a belt go without starting to shred.

It also states at the bottom of this solution, "If the this recommendation does not resolve the issue, then replace both sheave pulleys with AM132764 pulleys". I think these might be larger pulleys as my dealer had one of these on hand as they are for another application. Also in the solution it states to change the plate alignment to be lower in the back so the sheave pulleys best align with the engine pulley when the blower is in its down position. In this solution it does not indicate that there is a replacement plate available. But since this is a year old document, JD could have made one available.

Hope this helps and they get your blower fixed. Let me know what your dealer has to say.

Al

This is helpful. I will pass it along to the dealer and will let you know what happens.
