 LINDSAY MANUFACTURING CO. REPORTS FISCAL 2005 THIRD-QUARTER, NINE-MONTH RESULTS

OMAHA, NEB., JUNE 22, 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 third quarter and nine months ended May
31, 2005.

THIRD-QUARTER RESULTS
Third-quarter fiscal 2005 total revenues were $56.0 million, a 10 percent
decline from $62.3 million for the year-ago period. Net earnings were $4.0
million, or $0.34 per diluted share, versus $4.3 million, or $0.36 per diluted
share, in the prior year's third quarter.

Total irrigation equipment revenues declined 15 percent to $50.0 million from
$58.7 million in the prior fiscal year's third quarter, as lower worldwide
agricultural commodity prices reduced demand for irrigation equipment globally.
Domestic irrigation revenues declined 22 percent, while international irrigation
revenues increased 4 percent from the prior-year's quarter due to revenues from
Stettyn, Lindsay's South African subsidiary that was acquired in the last
quarter of fiscal 2004, and growth in export sales. Diversified products
delivered a very strong performance with revenues of $6.0 million compared with
$3.5 million in the year-ago period, an increase of 70 percent.

Rick Parod, president and chief executive officer, commented, "Demand for
irrigation equipment worldwide continues to reflect the combination of higher
costs for energy, fertilizer, and other agricultural inputs, as well as lower
crop prices, which have caused farmers to continue to defer their irrigation
equipment purchases. On the other hand, our diversified products business again
delivered strong revenue gains, reflecting our strategic decision to invest
additional resources into this business."

Gross margin improved to 22.4 percent from 20.9 percent a year ago, primarily on
pricing that fully reflected the steel cost increases of fiscal 2004. Operating
income was $5.7 million versus $6.1 million in the comparable fiscal 2004
quarter, and operating expenses were flat at $6.8 million, as savings due to
cost-reduction actions and lower insurance costs were offset by higher
Sarbanes-Oxley compliance expenses. Net earnings were $4.0 million, or $0.34 per
diluted share, compared with $4.3 million, or $0.36 per diluted share, in the
third quarter of fiscal 2004.

Lindsay's order backlog at May 31, 2005, was $11.1 million compared with $15.3
million at February 28, 2005, and $20.2 million at May 31, 2004.

NINE-MONTH RESULTS
Total revenues for the nine months were $137.2 million, a 9 percent decrease
from $150.3 million for the prior year's nine-month period. Total irrigation
equipment revenues of $121.5




million declined 14 percent from a year ago, while diversified products revenues
grew 78 percent, rising to $15.7 million. Net earnings were $4.8 million, or
$0.40 per diluted share, compared with $8.9 million, or $0.75 per diluted share,
for the first nine months of fiscal 2004.

Cash from operations for the nine months was $8.8 million, an increase of $9.5
million from the year-ago period. In the third quarter, Lindsay repurchased
approximately 186,000 shares of common stock at an average price of $18.69 per
share, for an aggregate cost of approximately $3.5 million. During fiscal 2005,
the company has used $6.6 million of internally generated cash to repurchase
approximately 324,000 shares. At May 31, 2005, the remaining amount authorized
under the company's current share repurchase program was approximately 881,000
shares.

Cash and marketable securities at May 31, 2005 were $53.7 million compared with
$57.2 million at May 31, 2004. Shareholders' equity at May 31, 2005, was $110.0
million, or $9.55 per outstanding common share, compared with $111.8 million, or
$9.50 per outstanding common share, at May 31, 2004.

OUTLOOK
Parod stated, "The softness in demand in the worldwide agricultural irrigation
market continues to adversely affect short-term demand and will impact our
performance in the fourth fiscal quarter. However, we have taken action to
prudently reduce costs and improve capacity utilization while maintaining our
strong competitive position. 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 continue to 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."

Lindsay's third-quarter fiscal 2005 investor conference call is scheduled for 11
a.m. ET today. This call will be simulcast and available over the Internet via
