        LINDSAY MANUFACTURING CO. ANNOUNCES VOLUNTARY REPAIR CAMPAIGN AND
                         ESTABLISHES CHARGE TO EARNINGS

OMAHA, NEB., AUGUST 3, 2005--Lindsay Manufacturing Co. (NYSE: LNN) today
announced a voluntary repair campaign of the end gun solenoid valves on certain
Zimmatic irrigation systems manufactured after 1993.

The campaign involves the grounding of the end gun solenoid valves to eliminate
the risk of electrical shock. The end gun solenoid valve is field-installed on
new Zimmatic irrigation systems. Lindsay has learned that, over time, as the
valve deteriorates, water may enter the valve body causing it to become
electrically shorted creating the risk of electrical shock during repair or
servicing. As part of the repair campaign, Lindsay is reminding the owners of
the affected Zimmatic irrigation systems and its dealers that they should follow
all manufacturers' instructions, which include turning off power to the system
before repairing or servicing any electrical component on a Zimmatic system.

"The safety of our irrigation systems is our top priority," said Rick Parod,
president and chief executive officer of Lindsay. "We are moving quickly to
voluntarily repair the affected Zimmatic end gun solenoids."

The company will record a pre-tax charge of $1.5 million, or approximately $0.09
per diluted share after-tax, during its fiscal 2005 fourth quarter for estimated
costs associated with the repair campaign.
