Nice looking fab work. I like the segmented rollers. I'll throw out another idea for a roller. Many years ago I helped a buddy build one for our grass runway. The rollers were a little smaller than yours, maybe 12"-14" but there were 4 of them in tandem. So the rolling area was about 8' wide by 6' long. the axles for the rollers were in bearings on heavy channel down each side. The idea was to carry each roller over small low spots and more weight on high spots. Filled with water it took a good size tractor to pull and we had to get well off the runway to turn around because of damage to the turf. Going straight down the runway it was amazing, smoothest grass I have ever landed on.
