I vote either upright or the choice not given.
Some of the Row Crop (and a few of the standards) Masseys had an exhaust that ran under the tractor and came out just under the rear axel on the right hand side.
I've always wanted to do this with Ryan's 10, but there isn't enough clearance with the 12" rears if he wants to plow.
My son votes for the upright also. I have aflapper for it I just didn't put it on. The farm store told me I could return it if it didn't look good on it as long as I did not scuff it up so it is just sitting there. I kind of like the clean look but the upright makes it look more like a big tractor.
Upright it will be.
I wish I had what they use to refer to as 3/4 cam in it. It would make that flapper go crazy. And NO even if they make such a thing I am NOT going to tear it apart and put it in.:smile1:
