   Picked up a Deere 826 yesterday.  The thing crapped out during the last storm with a brunt belt and the guy hurt is back shoveling so it got the boot. 

   Nice old buzzard rig but I can't find anything on it at the Deere site.  Anyone know where I can an exploded view?  I tried the usual places that have them and nothing on this one.   It's ID plate has P826J, 127489.  If I google P826J I get new models.  Nothing on the other number.

   The thing works fine after a belt replacement but it only tosses 3 - 8 feet with lots of low splatter.  I tried a few different belt sizes and tensions, and even over tight to insure no slip.  I can't see any slip with the cover off.  It has good grab, no crud in the V's, no obstruction in the housing.  It does have quite a distance from the arms to the lining, 1/2 inch.  The impleller is a 4 blade 12 inch and it should toss fairly well, 15-25. 

   Does anyone have this model and could tell me what it tosses like?  I can't see any problems so guess it's a design problem but at 3-8 feet hard to imagine they could make something that bad. 

   The motor certainly is not the problem, a Briggs Intek Snow 11hp a couple of years old.  I can drive into any condition snow and toss the same distance without engine sag.  Very impressive.  Anyone have a URL to an exploded view on the engine?  I can find one so I assume it a special for some maker.  It's got a 3/4 shaft.  3BSXS 3422HT 275387.  I can't get anything found at the Briggs site.  Googling I get 275385 which is a 10hp but nothing for 275487.  There are lots of hits for 3BXSX 3422HT but no motor like this.

I have the same exact machine with the same poor  throwing distance. Mine is all stock, including the 8 hp engine which runs strong. Belt is new and tight. I also have the same 1/2 inch gap between impeller blade and tube. I think this gap is the problem. I am considering trying one of those impeller kits.

Shryp, did you come up with a number for ft/sec out?  the impeller case is 12 but the impeller itself 11.  The actual pulley is 2 1/2 in diameter and the belt back is flush with the top of the pulley.  The bottom pulley is 8 inches. 

ahw2698,

   Do you have the part number for the engine pulley?  Do you know of an exploded view on-line?

   Does yours have the same number on the back plate as the number posted up top?

   Does your 8hp have a 3/4 or 1" crankshaft?   Mine is a replacement engine with a 3/4 crank end. 

   The pulley on mine is a double pulley.   Is yours a double pulley?  

   Earlier I figured I could just slap a bigger auger pulley on but since it's a double it will take some time to track down a single double or pair of individual pulleys.

   I'd like to mess with some kits.  I keep forgetting to go to a place for "farm belt".

   

 

I was just guessing on that number.

3600 * 2.5 / 8 =  1125 rpm.  That isn't too bad.  3" would get you 1350 rpm.

Very slow for an 11" impeller. 1350 would be a better speed. That 11hp Briggs could do even more, but you have other parts to worry about if you get carried away.

The model number on mine is slightly different than yours. Mine is P826H.  It looks just like the one in your picture, though. Maybe mine is a year or so older or newer?

I have not  had any luck obtaining parts diagrams. But I can tell you that mine has a 3/4 inch shaft and a double pulley. I'm pretty sure the pulleys are 2 1/2 inches. Engine and pulleys are original.

When I first aquired the machine, it only tossed maybe 4 feet max. After a new belt, it tosses up to 8 feet. Still not far enough. The impeller seems to spin quite nicely. When running without snow at full throttle, I can feel a nice strong breeze coming from the chute.

So it looks like you have the correct factory shaft / pulley combination. Plus you have 3 more HP than original plus the engine is newer.

Put in 826 in the Model Search box in the top left corner. Look at the results, first line: "1250 - 1032, 526, 726, 732, 826 and 832 Snow Blowers - 23Feb05"
I looked under the Sectional Index at the control console and it seems to match, so it's pretty close, if not the exact one.

Want a fast, cheap, and (somewhat) easy way to test out an impeller kit? Go to Home Depot where they sell the driveway sealer. For $5 you can pick up a squeegee head. Cut the length you need for each blade (take the rubber and the steel strip) and screw it on the impellers - drill a small hole and use like a #8 or 10 bolt, nut, and lockwasher. Put it on the top side of the impeller so you don't stress the little screws too much. May not hold up long but it will last long enough for you to decide if you want to invest in something heavier and more expensive. If not, the holes are small enough that you can ignore them. And if so, use those holes as guides for the real ones.

Bill_H,

   Nice, and thank you.  That's a match for mine.  OK on the squeegee head.  That's funny and I'll check out HD as it seems like it could be a possibility.

ahw2698,

    The hub has 4 short arms sticking out.  The drawings show that to be the handles for changing the differential.  Kind of a surprise.  It's won't move so probably rusted in place.  It has some external rust but otherwise in excellent shape.   It's feels ok to drive around and will probably make a nice machine when fixed.   The 11hp OHV is too nice for that but I have and 8hp and some spare pulleys.   The auger support is a bearing not a roller bearing.   The impeller shaft is tight but a surprise to see a bearing there. 

   Have you owned that since new?

   The pulley number is M45490.  Googling that I found a picture of one which is a double pulley.  In the picture the front auger pulley seems to be larger than the back drive pulley.  The two on mine are the same size. 

   I counted the RPM of the augers and they run at 100 RPM at 3600 engine RPM.  The ratio is usually around 10:1 so the impeller 1000 or around there 900-1100. 

Shryp: >>>600 * 2.5 / 8 =  1125 rpm.  That isn't too bad.  3" would get you 1350 rpm.

    When I checked the pulley yesterday I did it without a coat and too fast a check.  I rechecked today and it's 8.5 inches. 

2.5   = 1058, 3052 ft/sec

3      = 1270, 3664 ft/sec

3.25 = 1376, 3969 ft/sec

3.5   = 1575, 4543 fr/sec

A 3 inch pulley would get it up more in the range of a modern machine but the low end.  A 3.25 gets it in with Ariens numbers.  A 3.5 gets a good boost. With a 3.25 and some impeller arm extenders the thing could probably do 30-35 with good snow.  Snowmann is probably right about 1350 and not going too far.  With the bearing instead of a roller bearing much higher would probably take a toll. 

The auger clutch is a dash mounted throw lever so one hand is free all the time for changing chute direction.   With a 3.25 pulley and a taller chute this would be a nice machine.     

Checked the pulley stash and found a double pulley, 3/4 inch hole, 2 1/2 drive diameter, 3 auger, both for 1/2 in belts, with proper spacing.  Lucky find. 

The new pulley upped the auger rotation to 125 RPM determined by counting turns.  Hard to judge the start and finish but I think it might be a turn or two higher.  

The machine tosses exactly the same, 7-8 feet.  It can go through 2" or full bucket of four day old snow that's been double thrown onto, 8 feet.  No hesitation no belt slip.    I've tried 3 belts yesterday and a new belt today.  All had good tension and at times set to tighter than proper tension.  This machine is such a dog it's hard to believe.  At that speed with a short chute it should be capable of 15-25.     

Trouts, I see you are from MA. I am from So. NH. We had 6 inches of fairly heavy snow today. I only got about a 6 to 8 foot toss out of my 826.

Today there was a very heavy and deep EOD. Got about a 4 foot toss there. The machine never bogged down, even in the heavy stuff, just does not throw snow far. My auger pully is 2 1/2 inches.

It would be interesting to know what  throw distance these things were rated for when new. 

   It's a decent machine overall.  The linkage rods are not rusted, the tractor internals in great shape, good metal, great cast gearbox, cuts through tough conditions every well but just can't throw. 

  It's an 11 inch impeller in a 12 inch hole.  Ariens has a 10 inch impeller on some machines and if I remember right it it runs at 1410 and the rakes 140.  That is a 4 blade like our machines.  They run it that high to keep up the ft/sec rate out of the chute.  It does very well but the wall space is not like our machines.  On our machines it pretty wide.   Whatever other improvements can be done they will be wasted without first filling the space.  If that alone was done the machine would probably toss well enough to be minimally acceptable.

>>>It would be interesting to know what  throw distance these things were rated for when new. 

    Right.  What bothers me is how could they sell something like this.  It make me think I am missing something because I can't square how they could have sold what we have.
