Snowblower Help with Snowblower!!!

[JJZ 109]

Just an observation from looking at the pictures ...... isn't the angle of the pto driveshaft extreme ?

The left side view which shows the chute motor looks a little radical.

Exactly what I was thinking. Looks like a sure universal joint killer in this pic:

Looks like the top link is undone. Is the unit hooked up completely in that pic?

Looking at your picture I can see that your blower is turning the wrong way.I had the same problem with a blower and had to put in a reversing gear case.Here's what I know standing at the back of your tractor your pto turns clockwise which will make the impeller turn clockwise as well so its running backwards.Another thing to look at is that if you look at the chute you'll see its more to the right side of the blower but if you look at other 3pth blowers the chute is more to the left side.Thats why I know its turning backwards because mine is like that. As for the double shafts I'am not sure but if there's gears inside or behind that plate then one shaft will turn on way and the other one will turn the other way.Again I had the same problem with the one I mounted onto my newer tractor just this fall,So if the chute is closer to the right side it turns counterclockwise and if the chuts closer to the left side its clockwise rotation.Remeber this is looking at the snowblower from where the snow goes in.Hope this helps. As always Larry.

It sounds like its turning the wrong way, but your description has it turning the right way. My interpetation of the pics is the shaft youre driving is geared to the actual blower spindle [that other shaft], turning it the opposite direction that your pto turns. According to the pics and your description that is the right way and it should work...but it doesnt.

No... or...yes. As I noted in post 9 and as some have noted since, the pto is driving the spindle thru a gearset, reversing its rotation wrt the pto.

OP, Check that gearset to see if the 2 gears are different sized and have been interchanged. That could account for your observation of its slow speed.

After looking at the pics again I wonder if that thing was a front mount unit. It looks like all the 3ph mounts were added..

That may account for the severe driveline angles.

If not that then maybe the speed increaser is missing.

A little aside about Olathe Mfg. gleaned from a Google search:

In 1972 Buck and Steve Rogers started Olathe Manufacturing. Olathe started by building brush and tree chippers. Later they designed and built a professional turf care line with distributors and dealers across the country and worldwide. Steve and Buck owned and operated Olathe until 1994 when the Toro Company of Minneapolis, MN bought Olathe Manufacturing.

Seems like it was designed for a 2000rpm input speed. At least something much higher than 540rpm. The thought that this may have originally been a front mount sounds reasonable.

 

[etcallhome]

I'm like someone else said It looks like it might have been a front mount blower.

If so wouldn't pto speed be different ??

Have fun and be safe !!

As I see it that blower is for a reverse rotating PTO as found on early imports and many greys.
The shute would need to be on the left (looking from rear) for a standard rotation unit.
Since the impellor is on the PTO shaft which drived the augers via uger gear box.
For normal hook up on reverse PTO the center shaft would be used (the one not used in pix) and for reversing the blower for a nornal rt turning PTO you should be hooked up OK.

I presume that there are a pair of gears where the PTO shaft connects, one that provides direct coupling and the other reverses rotation.
If the gears are both same size then I would presume that the input is designed for 550RPM.

Since you are shearing pins a lot I'd suspect some bad bearings or other mechanical interferance.

Blowers generally turn the fan at or about PTO RPM's or 550 and the augers fairly slow or just enough to keep the fan full of snow.

Also I'd suggest you slightly offset your blower to try to center the PTO a bit better since you need to use the offset input. Otherwise said your PTO turns right and that blower needs to turn left.

Other than the gearbox and the reverser gears, everything else on that blower should be 'off the shelf' components found at any bearing supplier.

Good luck!

Your post reminded me that some of the small tractors have a 1000 rpm rear PTO. I think my B7500 is 960 rpm.

Both of mine are front mount and the 3940 turns the main shaft at 2000 rpm and the little one turns the main shaft about 2500 with a reduction to about 1500 on the fan shaft.

Ok, something is wrong there.

The chute on your blower is on the wrong side; all but 2 tractors in the world have a clockwise turning pto. So that blower looks like I am seeing it in a mirror, it is a reflection of a normal blower.

You say the impeller spins counter clockwise tho.

As someone else said, what is the deal with the 2 sharfts? There is no way, no way at all, that a short pto shaft should run at that much of a side-angle. It should be a straight shot to the impeller shaft. Your is off to the side. That whole angle thing and double shaft is - odd.

Looks like Torro bought out the manufaturer in 1994. Probably tough to get any documentation or info any more.

Would love to see what is up with that gearbox/ double shaft setup, and why the blower spins reverse to all normal blowers.

I am no expert in 3-pt snow blowers, so take this with a grain of salt.

In my opinion based on others comments and your pictures this was probably a front mount blower modified to a 3-pt mount. This would explain the chute on the wrong side and the 3-pt mount looking modfied. The second shaft was probably added off center to reverse the direction, but not geared for the pto speed difference between a front and rear pto.

As I said this is only my opinion hope this helps.

It looks like the impeller should be spinning counterclockwise as viewed from the auger side (rear) That is opposite from the design of my puma so, unless there are reverse gears in there, it may be running backwards. The impeller should be lifting snow up into the chute at high speed. Never seen one built like that before.

[Nick Danger]

OK, I think I did a poor job of explaining. Everything seems to be moving ok when hooked up. The auger turns and the blades (impeller) spin. It's when we put any snow at all in there, even with a shovel, it just spins around where the blades are until it just plugs up and we lose another shear pin. In the picture looking in the blower, the impeller spins counter-clockwise which seems to make sense because there are curved edges that would throw the now up and out of the shute. Let me know what you guys think. Also, what is the other shaft on the back of the blower for? It was obvious that the one we are hooked up to because it was the only one with any signs of use. We did hook up to that one but it didn't seem to make a differance.

Thanks all!

OK, here is my take...on my 560 looking at the back from behind the blower, the PTO spins CW. If yours spins the same way, according to your pic, it would be spinning backwards if hooked up to the center shaft. It looks to me by the housing, the 2 shafts have gears mated to each other. If you would hook it up to the center one, the blower would be spinning backwards if your shaft spins like mine. If you hook it up to the RH shaft (which you do) and again, if your shaft spins the same as mine, it would turn the other shaft in the correct direction for the blower...

When you have it running, do both shafts spin? or do they need to be engaged? also, if its hooked up this way, do your augers spin the correct way?

I am guessing that you need to move the drive shaft, unless the one is for a 1000 pto and the other a 540. Does your hitch get in the way of the shaft?

Hi everybody I do not know how come that snow blower has 2 shafts . I got a front snow blower on a kubota b7510hst . The front one got a chain reduction ( big gear on impeller shaf and smaller gear that is connect to the mid pto because the mid pto run over 2000 rpm . So if i want to put it at the back i have to by a 3 pt hicth kit and connect the pto direct to the impeller shaft . And i think for your blower 540 rpm not enough i had one on my other kubota i was running it at 900-- - and doing a perfect job. NOEL

 

[Steve_Miller]

I'm somewhat confused on direction of rotation on some models. Here are two links, one for a front mount and one for rear yet they both appear to have the chute ejecting from the same side with what looks like a direct drive on the fan unless the Kubota one feeds from the rear PTO which it doesn't state.

So Generalbegg... any more diagnosis? Does it need a gear up speed increaser or a front mount mid PTO bracket? Could be a whole new thread in the modification forum Or is it running OK now?

If you swap a blower end for end, direction of rotation stays the same. So, front or rear mount, the only issue is pto speed on the different ends of the tractor....

There is something going on with the gearcase of that blower, odd setup, that reverses direction. I suspect it is set up as a front mount & 1000 or 2000 front pto speed. Many tractors have a 1000 rear pto option, and it may be set up to work with those, but will be too slow at 540rpm.

But - that is all specualtion on my part.

[hdbikercouple]

the easy way to see if it is running backwards. start it up and throw a shovel of snnow into the auger's end. if it pulls it to the fan then it is running correct. the pto shaft still is angeled harded then any i seen. hope this helps and good luck.
