How long does a center pivot irrigation system take to make a rotation?

The speed of rotation (time it takes to complete one circle) of a center pivot system will depend upon the system size (length), pump capacity and the amount of water to be applied.

The time required to complete one revolution increases as the length of the system increases. A limited pump capacity or water supply can also increase the time to complete one revolution.

Each center pivot irrigation system has a percentage timer equiped that regulates machine speed. This controls the end drive unit to operate the stated percent of one minute. The rotation speed of the last tower will depend too upon tires size and gearmotors specifications.
