       LINDSAY MANUFACTURING CO. REPORTS FISCAL FIRST QUARTER 2006 RESULTS

OMAHA, NEB., DECEMBER 21, 2005--LINDSAY MANUFACTURING CO. (NYSE: LNN), a leading
manufacturer of center pivot, lateral move, and hose reel irrigation systems,
today announced results for the fiscal 2006 first quarter ended November 30,
2005.

FIRST QUARTER RESULTS
First quarter fiscal 2006 total revenues were $39.5 million as compared to $39.8
million for the year-ago period. Net earnings rose to $511,000, or $0.04 per
diluted share, compared with $175,000, or $0.01 per diluted share, in the prior
year's first quarter.

Total irrigation equipment revenues declined 4 percent to $34.1 million from
$35.4 million in the prior fiscal year's first quarter. Domestic and
international irrigation markets experienced similar percentage declines.
Diversified products continued to grow with revenues of $5.4 million compared
with $4.4 million in the year-ago period, an increase of 23 percent.

Gross margin improved to 18.8 percent from 16.5 percent a year ago. Improved
factory performance along with lower material costs were primary contributors to
the higher margins. Operating expenses of $7.1 million were essentially flat
compared with the prior year period, even with higher audit and Sarbanes Oxley
compliance related expenses and inclusion of $317,000 of pre-tax expenses
related to the adoption of the new accounting standard requiring the current
expensing of stock-based compensation. Operating income for the quarter was
$363,000 compared with an operating loss of $467,000 in the fiscal 2005 first
quarter. Interest and other income totaled $429,000 in the quarter compared to
$645,000 in the fiscal 2005 quarter. Net earnings of $0.04 per diluted share in
the first quarter of fiscal 2006 were negatively impacted by $0.02 related to
expensing of stock based compensation.

Rick Parod, president and chief executive officer, commented, "We are pleased
with the improved factory performance and the relatively steady market demand
while crop commodity prices remain depressed and with little relief in energy
and other farm input costs."

"Diversified products again turned in a very good performance," he continued.
"Revenues were up, and we saw continued improvements in that segment's margins.
While South Africa and Brazil irrigation sales have seen significant reductions
from currently depressed commodity prices, we are seeing improving markets for
irrigation equipment in the Middle East and Central America."

Lindsay's order backlog at November 30, 2005, was $20.9 million, up 58% from
$13.2 million at




November 30, 2004. The higher ending backlog for the first quarter of fiscal
2006 was influenced by earlier seasonal ordering by the Company's customers
compared with last year.

Shareholders' equity at November 30, 2005, was $109.8 million, or $9.53 per
outstanding common share, compared with $113.2 million, or $9.62 per outstanding
common share, at November 30, 2004. Cash and marketable securities at November
30, 2005, were $49.3 million compared with $43.6 million at November 30, 2004.

OUTLOOK
Parod added, "While short-term results are affected by agricultural commodity
prices and farm input costs, the long-term drivers for our business remain very
strong. The growing world population, demand for improvements in diet and the
need to conserve precious fresh water resources will continue to drive demand
for irrigation technology. In addition, our ongoing acquisition process
continues to yield prospects, which we are actively pursuing."

"In fiscal 2006, our most significant challenge will be to continue
strengthening our margins. The recent opening of our new galvanizing facility
will both improve the quality and efficiency of that operation. Our on-going
cost reduction programs will continue to improve the overall effectiveness of
our operations. Recently we have seen upward pressure on the price of steel and
some other raw materials which may put short-term pressure on margins, but
nothing like we experienced in 2004. We believe the competitive environment will
continue to allow us to pass through the increases realized."

Parod concluded, "Our long-term goals of sustainable revenue growth of 8 percent
to 12 percent, gross margin of 23 percent to 27 percent, operating margin of 10
percent to 13 percent and return on beginning equity of 14 percent to 20 percent
remain the same. 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."
