FOR IMMEDIATE RELEASE
THURSDAY, JUNE 30, 2005

          LINDSAY MANUFACTURING CO. ADJUSTS 2005 FISCAL THIRD-QUARTER,
                NINE-MONTH FINANCIAL RESULTS FOR SUBSEQUENT EVENT

OMAHA, NEB., JUNE 30, 2005--LINDSAY MANUFACTURING CO. (NYSE: LNN), a leading
manufacturer of center pivot, lateral move, and hose reel irrigation systems,
issued a press release on June 22, 2005 detailing the Company's financial
results for the third quarter and first nine months of fiscal 2005.
Subsequently, the Company settled a pending lawsuit through mediation on June
23, 2005. Under generally accepted accounting principles, the settlement of this
litigation requires that the Company increase the estimate of settlement costs
related to this matter as of May 31, 2005 by approximately $0.3 million. This
revised estimate is recorded as an increase in other current liabilities in the
accompanying consolidated balance sheets at May 31, 2005, and a reduction of
other income, net, in the accompanying consolidated statements of operations for
the three and nine months ended May 31, 2005. The Company previously reported
diluted net earnings per share of $0.34 and $0.40 for the three and nine months,
respectively, ended May 31, 2005. Including this adjustment, diluted net
earnings per share for the three and nine-month periods were $0.32 and $0.38,
respectively.
