                  LINDSAY MANUFACTURING CO. REPORTS FISCAL 2006
                        SECOND QUARTER, SIX MONTH RESULTS

OMAHA, NEB., MARCH 22, 2006 -- 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, 2006.
Revenues increased 32 percent from the same period a year ago, and earnings per
diluted share were $0.15 compared with $0.05 in the comparable prior year
period.

SECOND QUARTER RESULTS

Second quarter fiscal 2006 total revenues were $54.9 million compared with $41.5
million for the year-ago period. Net earnings were $1.7 million or $0.15 per
diluted share, versus $600,000, or $0.05 per diluted share, in the prior year's
second quarter. The current period includes a $0.02 unfavorable impact to
diluted earnings per share related to expensing of stock-based compensation.

Total irrigation equipment revenues increased 36 percent to $49.2 million from
$36.2 million in the prior fiscal year's second quarter, as farmer sentiment
improved with stabilized worldwide agricultural commodity prices and input
costs. Domestic irrigation revenues increased 42 percent, while international
irrigation revenues increased 22 percent. Diversified products revenues were
$5.7 million compared with $5.3 million in the year-ago period, an increase of 8
percent.

Rick Parod, president and chief executive officer, commented, "We are pleased
that demand for irrigation equipment continued to rebound from the prior year
when growers deferred purchases. While demand in most markets strengthened, the
markets in Western Europe, South Africa and Brazil remain depressed and we
continued our cost reduction actions in those markets during the period."

Gross margin declined to 18.0 percent from 18.7 percent a year ago. Gross
selling margins in the domestic market were slightly lower compared with the
second quarter of fiscal 2005 as a result of higher zinc and structural steel
costs. International gross margins were impacted by competitive intensity
particularly in the Western European market. The quarter's operating income was
$2.1 million versus $710,000 in the comparable fiscal 2005 quarter, driven by
the higher revenues. Operating expenses rose 10 percent to $7.8 million from
$7.1 million, due principally to inclusion of stock-based compensation expenses
of $421,000 and inclusion of factory consolidation costs in South Africa of
$186,000. Interest and other income totaled



$416,000 in the quarter compared to $363,000 in the fiscal 2005 quarter.

Parod stated, "We continue to take actions to reduce expenses and improve
efficiency across the global organization. I am also pleased with the continued
improvements in our global management of working capital."

Lindsay's order backlog at February 28, 2006, was $23.9 million compared with
$20.9 million at November 30, 2005, and $15.3 million at February 28, 2005.

SIX MONTH RESULTS

Total revenues for the six months were $94.4 million, a 16 percent increase from
$81.3 million for the prior year's six-month period. Total irrigation equipment
revenues of $83.3 million rose 16 percent from a year ago, while diversified
products revenues grew 14 percent, rising to $11.1 million. Net earnings were
$2.2 million, or $0.19 per diluted share, compared with $775,000, or $0.06 per
diluted share, for the first six months of fiscal 2005. The six month results
include a $0.04 unfavorable impact to diluted earnings per share related to
expensing of stock based compensation.

Shareholders' equity at February 28, 2006 was $111.9 million, or $9.70 per
outstanding common share, compared with $110.2 million, or $9.45 per outstanding
common share at February 28, 2005. Cash and marketable securities at February
28, 2006 were $50.9 million compared with $43.8 million at February 28, 2005.

OUTLOOK

Parod stated, "In the United States, the USDA projects net farm income to be
lower in 2006 due to lower production, lower commodity prices and higher input
costs; yet, irrigation equipment demand remains strong due to improved farmer
sentiment and dry conditions. Globally, long-term drivers remain positive as
population growth, the need for productivity improvements and fresh water
constraints drive demand for our irrigation technology."

"Strengthening our margins during a period of rising steel and zinc prices
remains a challenge given the short-term competitive environment. We have taken
actions to tightly control production costs while maximizing our throughput
during our peak selling months. We are also continuing growth initiatives
related to finding accretive acquisitions in infrastructure and water products.
We will continue to pursue our growth initiatives and leverage our strong cash
flow and financial flexibility to create shareholder value through a balance of
organic growth opportunities, accretive acquisitions, share repurchases and
dividend payments."
