Tough to say Kevin. Remember too that your decking will need to be able to take the point load from the tractor wheels.

How much does the tractor and implements way? I imagine somewhere between 4 and 8k?


I just finished some drawings with 150 psf load for the hay loft.
Thankfully the first floor is @ grade. Cows are heavy!

My guess is that you'll be looking at 150 to 200 psf to start. Likely 3x decking if you are bringing in vehicles.
