5' kabota 3 pt snowblower

[steviep]

I have a 5 ft wide Kubota snowblower on the back of my jd 4300. It seems to blow only about 5 or 10 ft. It seems to me it should blow further than that. I have the pot a full speed , is there something I might be missing

Well, when I had a snow blower - how far it would throw the snow depended almost totally on the condition of the snow. Wet, heavy snow will not throw at all or at best only a very short distance. I found the frozen "crunchy" snow - the kind the auger has to chew up - would go the furthest. Light, dry, powder snow goes quite a ways too but usually a lot drifts back on you.

I had a 5 foot snow blower/thrower - snow is actually thrown, not blown - on a Ford 1700 with 28 engine hp. With crunchy frozen snow this unit would throw the snow 40-60 feet. At times with wet, heavy snow - all it would do was plug the discharge chute.

What is the diameter of the impeller and how many paddles does it have ?

I have a John Deere Frontier 64" wide 3pt. snow blower behind my Kubota B7800 with 22 HP pto. at 540 rpm pto,
It will blow snow over 35 feet. The impeller diameter is 24" with four paddles.
Prior to that I had a Pronovost Puma 64" wide rear mount which had a 20" diameter impeller with 4 paddles, it would blow snow at least 20 feet.

The larger the impeller diameter, the greater the snow throwing distance and as the gap increases between the end of the impeller paddle and the impeller housing, snow throwing distance decreases.

This impeller gap distance is not always uniform and can vary with in the housing at different clock points, check at 12 - 3 - 6 - and 9 o'clock positions.
There are impeller modification procedures to decrease this gap using mudflap material.
Do a search on youtube - impeller modification

It should definitely throw further than 5 - 10 ft.
How big is the gap between the impeller and the housing?
Over time the gap can open up, due to abrasive wear from dirty snow and gravel/stones.
As DHD mentioned, there are kits & DIY fixes to close the gap up and restore performance, if that's the problem.

I have a Kubota 50 inch rear mounted blower on my BX (snowblower model B2789). Just checked the clearance impeller gap and it averages about 3/16 inch. The blower quit blowing just once and that was in very heavy and wet snow. (But I have had pto shear pin break a couple of times). This video (was posted on TBN earlier) gives some idea about its performance with deep snow and fairly cold temp (-9 C). http://youtu.be/PjBw4M82KUQ

I will have to check that out guys at the present time work has me away from my tractor. It seems to me that this idea might also help out with not breaking as many shear pins.reducing the gap means less places for rocks to jam in.

You can compare blowers right in the shop too. If it don't blow air...it won't blow snow. Good blowers will clean the dust off the lights in the shop while wimpy blowers hardly move any air.

Is your blower maybe a B2782 ???
I have a B2781, same as B2782 but only 51" wide. These blowers are typically used as front mount on B series Kubotas, using a gear reduction to reduce mid pto down to about 800 or 900 rpm. Google Image search will show what they look like with gearbox. My unit is direct drive from the 540 pto, so max 540 rpm on the impeller, and does not throw snow very far, clogs easily with wet heavy snow. Also, the impeller housing is fairly small, about 17".

Don't bother. No offense to the earlier poster, but reducing the fan/housing gap does nothing, with the 2nd order exception of making the fan blades slightly longer. Any fan/housing gap packs in with snow almost instantly, so the actual fan/housing gap is generally zero or close to it at all times. Improving blower performance by minimizing of this gap is a popular myth.

You have to prep to run a blower. Clean up your driveway and throw the sticks and big stones out of the way BEFORE the snow flys - that's how you avoid breaking shear pins.

Your B2789 is a 540 PTO blower, so relative speed should be OK. Are you sure your BX is actually running at proper full-blast PTO speed? Even a little less RPMs makes a significant difference. Also, if you really pack up the blower, it will reduce the throw substantially. With all of the snow we've been having the last few weeks, it is possible that you are simply driving too fast to keep the blower clearing itself out. Try going a little slower and see if it makes a difference.

I don't think we know that the OPs blower is a B2789... another TBNer mentioned he had one.

Fan blade gap is not a myth. The longer your blades are, the faster the tip speed is which equals more blowing power. As far as the housing packing with snow to fill the gap, that is exactly what you DO NOT WANT. That packed snow creates more friction which reduces blowing power. Packed snow has much more friction than smooth metal. Performance of a blower can be improved greatly by having the blower fan set up properly.

I believe my snowblower is a 2563. I will find out for sure later.

 

[steviep]

My snowblower is a B/L 2563 . I talked to a friend of mine and he asked if this blower is suppose to be hooked up to a 2 speed pto . He tells me that some Kubota ran a higher speed pto .
