Hi,

Glad I found this forum...wow!

I have an 870 JD with a frontier snowblower that used to belong to my father, now to me. I had thought this when he owned it, but wanted to get some input before the snow flies here soon. The snowblower works, but I feel as though it's not turning or throwing the snow as fast or far as it should. Also, when the snow seems to not get eaten up as fast as I think it would. I don't see any gear changes on the rear PTO, so I'm assuming this is just the rpms it runs at. I'm not running it with not enough throttle either I don't believe. Thoughts? I just feel the snowblower itself should be chugging through it better than it does.

Thanks for any input.

Regards,
Bill

First off, :wgtt:

Which Frontier snowblower are we talking about here? Got a model number? Is this a front mounted or rear mounted blower? (I'm guessing rear mounted but just to be sure...)

Welcome to GTT,
If it's rear mounted blower on the 3PH, then the rear PTO needs to turn are 540 RPM, there should be a yellow indicator on the tach for this-probably around 2500ish. If you are running there, then you can check the fan blade clearance, if to much it won't throw very well.

Affirmative. I do run it at 2500 when throwing snow. What do you mean by 'fan blade clearance'?

The "fan" is the second stage, check the clearance between it and the housing. Also, if the PTO shaft has a "slip clutch" on it (optional) it could be slipping if adjusted to loose. Post some pictures and we can help ID exactly what you have.

The distance from the edge of the casing is about 1/4" seems pretty tight.

The slip clutch I did read about in the manual, but I'm can't say I know for sure ours has it. I'll check today bringing over the manual to the tractor.

Thanks!
