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.

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.
