TheFlatlander,
I certainly appreciate your feedback. We purchased a used Kubota this summer that was equipped with turf tires (foamed in rear). So far I have not had anything that I could not do with the turfs although I do rely on the dif-lock for steep terrain when failure is dangerous and, today, FEL work with 70 yards of red clay that we had brought in.
While our rears are foamed, the fronts are air only. While lifting and erecting heavy steel, I had to max out the pressure at 30 psi. I would have preferred 30 psi in a tire rated for 35+psi since I was spooked by the warning that explosion may occur with pressures over 30psi.
I really enjoy how easy the turfs are on our irrigated areas. I can run all day across grass with heavy loads, turn on the sprinklers at night, and the grass looks the same by the next evening. The other day, I let a tractor-style ditch witch that was working in the ROW cut across the property to save him a long drive around, and his R4s did damage to the lawn.
Before having any experience with turf tires, I assumed that R4s would be perfect for our property and am still interested but unsure. Your post helps. I certainly would not want to tear up my lawn, would not want to be restricted by a lack of traction. My fingers are crossed that these turfs keep impressing me as they have every day that I have used them. :thumbsup:
