 LINDSAY MANUFACTURING CO. REPORTS FISCAL 2005 SECOND-QUARTER, SIX-MONTH RESULTS

OMAHA, NEB., MARCH 23, 2005--LINDSAY MANUFACTURING CO. (NYSE: LNN), a leading
manufacturer of center pivot, lateral move, and hose reel irrigation systems,
today announced results for its fiscal second quarter ended February 28, 2005.
Revenues declined 19 percent from the same period a year ago, and earnings per
diluted share were $0.05 compared with $0.29 in the year-ago period.

SECOND-QUARTER RESULTS
Second-quarter fiscal 2005 total revenues were $41.5 million compared with $51.5
million for the year-ago period. Net earnings were $600,000, or $0.05 per
diluted share, versus $3.5 million, or $0.29 per diluted share, in the prior
year's second quarter.

Total irrigation equipment revenues declined 26 percent to $36.2 million from
$48.7 million in the prior fiscal year's second quarter, as lower worldwide
agricultural commodity prices and increased equipment prices reduced demand for
irrigation equipment globally. Domestic irrigation revenues declined 31 percent,
while international irrigation revenues decreased 11 percent. Diversified
products delivered a very strong performance with revenues of $5.3 million
compared with $2.7 million in the year-ago period, an increase of 94 percent.

Rick Parod, president and chief executive officer, commented, "Demand for
irrigation equipment in the second quarter was impacted by several global
factors that caused farmers to defer purchases. Domestically, while agricultural
commodity prices are still good, we have seen them come off of their highs from
last year, and grower input costs, particularly energy and fertilizer, have
risen. Additionally, each of our international operations has seen similar
conditions."

Parod added, "Conversely, our diversified products business delivered a strong
performance. Our relationship with GE Transportation Systems, Global Signaling
is progressing nicely and we are continuing our efforts to expand this
relationship, as well as develop new customers."

Gross margin declined to 18.7 percent from 22.6 percent a year ago. Gross
selling margins in the domestic market improved over the first quarter of fiscal
2005, however, they continued to be negatively impacted by higher overhead
allocations per unit due to lower production levels. International gross margins
remain lower than domestic margins, but they continued to improve, rising
slightly above those recorded in the first quarter of fiscal 2005. The quarter's
operating income was $710,000 versus $4.8 million in the comparable fiscal 2004
quarter. Operating expenses rose 3 percent to $7.1 million from $6.8 million,
due principally to higher insurance and compliance costs, and inclusion of
Stettyn, the South Africa acquisition completed during the fourth quarter of
2004. Net earnings were $600,000, or $0.05 per diluted share, compared with $3.5
million, or $0.29 per diluted share, in the second quarter of fiscal 2004.





Parod stated, "We have initiated actions that stabilized our steel costs.
However, our margins still need to improve, and we have taken action to increase
efficiency throughout the organization. We have reduced our manufacturing
overhead and SG&A costs to reflect current capacity utilization and near-term
demand for our products. At the same time, we are continuing investment in
growing our diversified products business and in expanding our acquisition
activity."

Lindsay's order backlog at February 28, 2005, was $15.3 million compared with
$13.2 million at November 30, 2004, and $32.2 million at February 29, 2004.

During the second quarter, Lindsay identified a material weakness in internal
controls over financial reporting related to the review of manual journal
entries, which occurred due to vacancies in two financial management positions
at November 30, 2004. The Company filled these positions during the second
quarter. In addition, the Company has reasserted its policy over review of
manual journal entries. There were no other significant changes in Lindsay's
internal controls during the period and the Company believes it is progressing
on the internal control review generally according to the plan for fiscal 2005.

SIX-MONTH RESULTS
Total revenues for the six months were $81.3 million, an 8 percent decrease from
$88.0 million for the prior year's six-month period. Total irrigation equipment
revenues of $71.6 million declined 13 percent from a year ago, while diversified
products revenues grew 83 percent, rising to $9.7 million. Net earnings were
$775,000, or $0.07 per diluted share, compared with $4.6 million, or $0.38 per
diluted share, for the first six months of fiscal 2004.

Shareholders' equity at February 28, 2005, was $110.2 million, or $9.45 per
outstanding common share, compared with $108.3 million, or $9.21 per outstanding
common share, at February 29, 2004. During the second quarter, Lindsay
repurchased 138,500 shares of common stock at an average price of $22.93 per
share, for an aggregate of approximately $3.2 million. At February 28, 2005, the
remaining amount authorized under the company's current share repurchase program
was approximately 1.1 million shares. Cash and marketable securities at February
28, 2005 were $43.8 million compared with $50.3 million at February 29, 2004.



OUTLOOK
Parod stated, "In the United States, farm income hit record levels last year and
while farm income will be strong during the current year, farmers are
anticipating lower earnings due to the drop in commodity prices and rise in
input costs. Normally, we would expect to have some offset from our
international operations, but lower commodity prices and a weak dollar are
dampening demand worldwide.

"While the near-term environment has softened, the long-term drivers of our
business remain robust. Water continues to become more valuable and farmers are
seeking ways to reduce costs and increase productivity," he added. "We will
pursue our growth initiatives and leverage our strong cash flow and financial
flexibility to create shareholder value by seeking a balance of organic growth
opportunities, accretive acquisitions, share repurchases, and dividend payments.
Through these initiatives, we will continue to pursue our previously stated
long-term goals of sustainable growth in revenues, gross margins, operating
margins, and return on beginning equity."
