Irrigation uniformity can be reduced by wheel track rutting because of tire slippage (Meyer & Hoffman, 1983). These impacts can result in costly repairs to equipment, including gear boxes (about $700 each) and center-drive motors (about $550 each), or hydraulic pumps and motors on certain makes of pivot. Labor and crop damage associated with freeing or repairing a pivot or caused by downtime can also be a great expense to the farmer. This guide covers different strategies for managing wheel track rutting for center pivots and lateral-move systems.
