I bought a Kruckman dust fan a few years back, its mechanically driven and has dual fans and is worth its weight in gold.
The problem is I don't know if he is still in business? I called last yr for parts (bearings) and the phone # was no good, and no one seems to know of him. His name is Harold Kruckman, company name was Kruckman products.
There are a few others, the johnson diverter being the most popular, however 2 local combines that run them have had the hyd motor start leaking during harvest and had to unhook them.
Its a problem with all conventional machines. The screw design of a rotor creates enough of a vacuum that it draws air into the feeder house thus greatly helping with visability. Like other rotaries, the Deere rotary does not have a dust problem out front.
Currently is $1250. One is ordered and should be here in a few days. If I have time, I'll take pictures of the kit with before and after pics while running.
I don't know about other makes of combines, but I think the cylinder machines carry some chaff over the cylinder and throws some back into the feeder chain. Then out the front it goes. I imagine the feed accelerator on the STS's does some of the same. A straight rotor machine like the TR/CR's and others don't have any forward rotating components behind the feeder to create that situation. Seems like rotor machines also draw air from the feeder bacause of the augar cones on rotor(s).
Edit: oops, kinzepower already answered while I was typing.
Have you installed your EZ-View Dust Diverter? Do you have any pics? I was wondering what you thought of the install process, since it is fresh on your mind. I have been considering buying one of these. Milo harvest is rapidly approaching, and MAN, the dust can get BAD!
You guys that have these...are they really worth the cash? Do they really do the job? Go with the EZ-View Dust Diverter
Thanks for the reply; and yes, I did read your comment(s). I was wanting to get other people's opinions, too, regarding the blower/diverter. It's been my experience that things usually work & turn out better when a bunch (or at least more than one) of people like it. I was hoping about 6 people would jump in and say they like it....That would make me more comfortable....I don't doubt your word...I was just wanting others, too.
