I recently purchased a building. Most difficult was deciding dimensions. But haven't paid for it all yet, so that might be more painful. A guy wants it big enough to get machinery in for the future but keep cost down on building and heating. I will have a 22' x 50' door in one end. 22' clearance under trusses. My overall sq footage will be less than yours but not by much.
On your combine purchase were you intentionally staying away from the new S series?
How many sep. hrs did you get to on your 60 series?
Sounds like you will have a nice shop too. Lots of height, good choice, lots of room for taller equipment in the future. We have insulation under the floor, in floor heat, R28 in the walls and R40 in the attic. most winter months it costs around 150 dollars to heat it. It has been a very worthwhile addition to the farm.
Yes we did intentionally stay away from the S series. Have heard and seen some not so good things about them. Decided to stick with the 70 series. Not that easy to find two the same with relatively low hours. Our 9660 had 1568 sep hours on it and our 9860 had 1204.
