Ol' George is right. Think about a piece of threaded rod. Twist it right to screw in... Turn it around it still turns the same way. Flipping the fan is not the answer.

I understand now what you guys are saying about the blade, you guys just saved me from buying the adaptor cuting it etc.
I guess I will look into removing the blade and install an electric fan blowing out.

About the threaded rod though, if you turn the nut to the right the nut turns on , if you flip it over and countinue turning it in the same direction it turns off.

If the fan was like a threaded rod it would work. But its not I see that now. Thats what thru me with the blade, the fins will be the wrong angle.

I'll post back if I get the electric fan working, any good ideas where to get the power for the fan from?

don't own a cab but have you tried running with the system set for fresh air instead of recirculation the fresh air setting should make a slightly positive pressure in the cab and keep the dust out.

where is the intake for the ventilation system on the b3030 might be easier to relocate that.

Thanks for your reply jonsstihl

.
That is the theory but does not work well. I think the engine fan is too much to compete with the cab a/c fan for that theory to work well. The cab has too many other holes in it and the air takes the path of the least resistance.
I have pretty much tried everything at this point but the fan.
The intake is up on the roof in the rear the best place it can be up high with a good size filter. Others will say they don't have this problem with the B3030cab but they either are not sensitive to the engine fumes or they don't do a lot of grading in dirt back and forth over and over. That is where most of the dust comes from.

Your problem is really negative pressure in your cab. Fooling with the fan will do nothing. You have to introduce outside air into your cab to keep dust from entering. Keep the cap slightly positive will keep dust from entering.

How do you do that?
If you stop the engine air from blowing into the cab you will have positive pressure from the a/c in the cab. Right now there just isn't enough of it.(I think anyway)
Any ideas on how to increase the blower 2 fold in the cab just to keep it positive.

The engine 12 inch fan blade vs 6 inch squirrel cage in the roof.
I am open to any and all suggestions.
but I think stopping engine air from coming in is worth a try. If the engine fan is sucking the air from the holes etc. in the firewall wouldn't that help the a/c /heater blower in keeping it positive inside the cab?

Here is a picture of the a/c fan from last year when I had it all apart to try and solve the problem. as you can see not much compared to the power of the engine fan.
Any ideas to help solve this problem would be greatly appreciated.

I was going to make the same suggestion and it works for me. The other simple solution that you might try first is to adjust the door and window latches to get a better seal. In any event, I have worked in really dusty conditions for a while this summer and got no dust inside.

I checked those windows before, no leaks, its not only the dust its the engine fumes also, it also doesn't happen right away it takes time I would be very surprised if your tractor is any different then mine it's just how we use them that is different. If you had to do a big job it will get pretty dusty.

I think DELInstallations, and DanD78 are right something like this may be the way to go. Can't hurt to try. I'll order another shroud and get this fan, mount it up then I'll just swap the shrouds and remove the factory blade the same time. it will fit right inside the fan shroud, It pulls or pushes.

I have plan that may work well for you in the pursuit of a pressurised cab solution for your B3030.

First
It would would require you to buy a high output Kubota alternator

Second.

Purchasing of a large donaldson two cartridge diesel engine air filter assembly with mounting brackets.
Third.
Purchasing a 12 volt squirrel cage fan to blow outside air into the air filter and then into the cabin at some desired entry-perhaps the roof with some flexible rubber hose from the clean air side of the air filter unit.

It would be possible to mount everything on the roof but I do not know what your vehicle clearances are for the tractor to enter covered storage etc.
the finding s suitable place to mount the air filter could allow placing it upon the right fender and using flexible hose to follow the corner of the tractor cabin to the roof line.

Operating in winter woukld require some planing as far as installing a restrictor in the out let to not let too much cold air in to keep the cabin pressurised.

I thought the exhaust was coming in my cab too, the first thing I did was make a stack to get the exhaust up and away it worked for the exhaust. But I found out that it was not only the exhaust coming into the cab it is the air running across the hot dirty smelly motor coming into the cab. After plowing snow for an hour with the heat on it's sickening ,for me anyway. The stack is nice you never smell diesel around the tractor at all.
It's either dust , dirt and the smell from the motor in the summer, and in the winter the smell across the motor. One way or another I'm either going to stop it or sell the tractor.

I'll be more than willing to swap my 2620 TLB for ya, problem solved!
