              LINDSAY MANUFACTURING CO. REPORTS FISCAL 2004 SECOND-
                   QUARTER, SIX-MONTH RESULTS; UPDATES OUTLOOK

OMAHA, NEB., MARCH 23, 2004--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 29, 2004.
Revenues grew 7 percent from the same period a year ago, and earnings per
diluted share were $0.29 compared with $0.42 in the year-ago period, as rapid
increases in steels costs led to lower gross margin. The company also reported a
58% increase in its order backlog over the year-ago period.

SECOND-QUARTER RESULTS

Second-quarter fiscal 2004 total revenues were $51.5 million, up 7 percent from
$48.1 million for the prior-year period. Irrigation equipment revenues were up 8
percent to $48.7 million as domestic irrigation revenues increased 3 percent
while international revenues, including exports, grew 24 percent. Diversified
products revenues were unchanged from the fiscal 2003 second quarter, but rose 8
percent sequentially.

"U.S. farmers are enjoying good profitability, worldwide agricultural commodity
prices are strong, and awareness of the need to make efficient use of existing
water resources is growing. These factors are driving continued strong order
flow from both domestic and international customers, even with pivot price
increases due to escalating steel costs," said Rick Parod, president and chief
executive officer. "Additionally, we are pleased to see the sequential upturn in
diversified products. We have been working diligently to bring in new business
from various industrial sectors and this quarter, we won a new project for a
division of a Fortune 500 company."

Gross profit was $11.6 million compared with $12.3 million and gross margin
decreased to 22.6 percent from 25.5 percent year-over-year, reflecting the
significant increases in steel costs. Operating expenses increased, as planned,
primarily reflecting increases in domestic and international irrigation sales
personnel costs, general corporate and group health insurance costs, and
incremental legal and professional fees required to support Sarbanes-Oxley
initiatives. Operating income of $4.8 million compared with $6.5






million during the same period last year. Net earnings were $3.5 million, or
$0.29 per diluted share, compared with $5.0 million, or $0.42 per diluted share,
in last year's second quarter.

Commenting on the margins, Parod said, "While we instituted a 3 percent price
increase on orders received on or after December 1 and another 3 percent
increase as of February 1, steel costs have continued to rise with unprecedented
speed, and we have not been able to pass on the increased costs quickly enough
to maintain our margins. As of March 1, we have instituted a steel surcharge on
all orders."

Lindsay's order backlog at February 29, 2004, improved significantly to $32.3
million compared with $21.9 million at August 31, 2003 and $20.4 million at
February 28, 2003.

SIX-MONTH RESULTS

Total revenues for the six months were $88.0 million, an 8 percent increase from
$81.6 million for the prior year's six-month period. Irrigation equipment
revenues of $82.7 million grew 9 percent from a year ago, while diversified
products revenues were $5.3 million, or 5 percent less than the previous year.
Net earnings were $4.6 million, or $0.38 per diluted share, compared with $6.1
million, or $0.52 per diluted share, for the first six months of fiscal 2003.

Shareholders' equity at February 29, 2004, was $108.3 million, or $9.21 per
outstanding common share, compared with $98.0 million, or $8.35 per outstanding
common share, at February 28, 2003. Cash and marketable securities at February
29, 2004 were $50.3 million compared with $41.2 million at February 28, 2003.

OUTLOOK UPDATE

Lindsay continues to expect that revenues will grow approximately 8 to 10
percent for fiscal 2004. "On the domestic front, we are still seeing strong
commodity prices and good farmer profitability, which are driving demand for our
products. International commodity prices, especially for soybeans, are also
strong, and our overseas operations will benefit from these factors. We have
just completed the move into our new facility in Brazil, which will more than
double our capacity there," Parod said.

"However, given the unprecedented and continued increases in steel costs, we no
longer expect growth in earnings and earnings per share in fiscal 2004. Earnings
are now projected to be between the levels achieved in fiscal 2002 and fiscal
2003," he added.

Parod continued, "We are also taking action to more tightly control operating
expenses at each of our operating units and we expect to see operating expense
leverage during the full fiscal 2004 year. We are making progress toward our
goal of leveraging our international operations by increasing volume and
improving efficiencies to bring their margins up near the levels earned in the
domestic market.

"We have the strong cash flow and financial flexibility to create shareholder
value by pursuing a balance of strategic acquisitions and organic growth to
support our mission to






be the worldwide leader in providing intelligent water and plant nutrient
management systems that improve productivity and result in efficient utilization
of natural resources," Parod said.

Under Lindsay's share repurchase plan, management has an existing authorization
to purchase up to 1.3 million shares of the company's stock, depending on market
conditions and other considerations.
