On flat ground, a center pivot is subjected to certain stresses in certain proportions, all of which it is
designed to easily handle . However, when the machine is subjected to various slope conditions, stresses
and their proportions to each other change dramatically .
In a longitudinal slope situation as shown in Figure 1-6 .a ., the spans are placed in either tension on a
descending slope (as shown) or compression on an ascending slope . Exceeding the slope limitations set
forth could create excessive tension and compressive forces in both spans, and especially the pivot point .
