A grower can simply run his pivot as he normally does. ConstantDrive utilizes a patented method of integrating analog alignment sensors with VFDs (variable frequency drives) to precisely control the output speed of each AC motor in order to maintain string-straight system alignment. A single VFD independently adjusts the center drive motor speed at each wheel tower and, if needed, a service switch allows the operator to manually select between VFD mode and start-stop mode as a failsafe backup for further prevention of irrigation system downtime. ConstantDrive is a disruptive innovation that completely eliminates the start- stop movement at every center pivot wheel tower to achieve faster, more efficient variable-speed irrigation. Wilcox anticipates a 5 percent increase in Russet Burbank No. 1s just from the uniform distribution of water using ConstantDrive in combination with LESA (low elevation spray application) for mitigating wind drift. In this way, water is essentially being applied like a paintbrush. Improved distribution uniformity equals increased irrigation efficiency that, in turn, results in higher quality and yield. "We believe in adapting technology to our farming practices," said Boardman, Ore., grower Vern Frederickson, Grower Tyler Cranney sees uniform water distribution and reduced wear on drivetrain components as the greatest benefi ts.
