NOTE 1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Interim Financial Information

     The accompanying unaudited, consolidated financial statements have been
prepared in accordance with generally accepted accounting principles for interim
financial information.  Accordingly, they do not include all of the footnotes
required by generally accepted accounting principles for complete financial
statements.  In the opinion of management, all adjustments (consisting of
normal, recurring adjustments) considered necessary for a fair presentation have
been included. Results for the interim periods are not necessarily indicative of
the results for an entire year.

Reclassification

     Certain 1998 amounts have been reclassified to conform with the
presentation in the 1999 financial statements.

NOTE 2.  CONTINGENCY

     The Year 2000 issue relates to limitations in computer systems and
applications that may prevent proper recognition of the Year 2000.  The
potential effect of the Year 2000 issue on the Company and its business partners
will not be fully determinable until the year 2000 and thereafter.  If Year 2000
modifications are not properly completed either by the Company or entities with
whom the Company conducts business, the Company's financial condition and
results of operations could be adversely impacted.

For the three months ended September 30, 1999 and 1998.

     Net Sales. For the three months ended September 30, 1999, net sales were
approximately $8,781,000, compared with approximately $11,398,000 for the same
period in 1998. The main factor for the decrease is the overall decrease in
Posi-Track related sales which is the net effect of three primary items. First,
ASV's sales were affected by the continued transition of selling the Company's
Posi-Track products to the Caterpillar dealer network. It is the Company's
belief that Caterpillar dealers, due to their large size and extensive
geographic coverage, follow a more deliberate, structured approach to taking on
new product lines such as the Posi-Track than ASV's independent dealers.
However, the Company believes these larger dealers are capable of placing
greater unit orders than ASV's independent dealers. Second, during the third
quarter of 1999, the Company experienced unexpected production delays as it
began manufacturing its newest model Posi-Track, the 4810. These production
delays prevented a greater number of these units from being manufactured in
third quarter, thereby reducing net sales for this product. Third, the Company
had net sales of approximately $1.7 million on a military contract for the sale
of specially equipped Posi-Tracks during the third quarter of 1999. The Company
had no similar sales during the third quarter of 1998.

     Gross Profit. Gross profit for the three months ended September 30, 1999
was approximately $1,586,000, or 18.1% of net sales compared with approximately
$2,804,000, or 24.6% of net sales, in 1998. The decreased gross profit was
attributable to decreased sales volume and a lower gross profit percentage for
third quarter 1999. The decreased gross profit percentage was attributable to
two main factors. First, the Company experienced production inefficiencies
during the start up of the production line for the 4810, which resulted in lower
unit production. Second, gross profit percentage was reduced due to the large
subcontract costs on the military contract completed in the third quarter of
1999. The gross profit percentage on the contract was as expected, approximately
12%.

     Selling, General and Administrative Expenses. Selling, general and
administrative expenses increased from approximately $833,000 for the third
quarter of 1998 to approximately $1,388,000 for the same period in 1999. As a
percentage of net sales, selling, general and administrative expenses increased
from 7.3% of net sales in third quarter 1998, to 15.8% of net sales in third
quarter 1999. The increased dollar volume was due to several items. First,
during third quarter 1999, the Company had increased start up, training and
market development costs relating to new dealers. Second, the Company had
increased compensation costs as sales and administrative personnel have been
added to support expanded sales and customer service roles. Third, the Company
had increased costs related to the commission paid to Caterpillar Inc. for sales
of products to Caterpillar dealers, which accounted for one third of the
increase in selling, general administrative expenses. Consequently, the
increased expenses combined with the decreased sales caused an increase in
selling, general and administrative expenses when expressed as a percentage of
net sales.

     Research and Development.  Research and development expenses increased from
approximately $77,000 in third quarter 1998 to approximately $149,000 in 1999.
The increase was due mainly to the development of the Company's new, smaller
concept vehicle and work on the development of a rubber tracked agricultural
tractor.
<PAGE>

     In order to maintain its competitive advantage over other manufacturers of
similar products, the Company believes it will increase the level of spending on
research and development activities.  It is expected the main thrust of these
activities will be directed towards extensions of the Company's current product
lines and improvements of existing products.

     Interest Expense.  Interest expense decreased from approximately $128,000
for the third quarter of 1998 to approximately $63,000 for the third quarter of
1999.  The decrease was due to the elimination of the interest expense in 1999
for the Company's convertible debentures, which were exchanged for common stock
in the fourth quarter of 1998, offset in part by increased interest expense due
to greater line of credit usage.

     Net Income.  Net income for the third quarter of 1999 was approximately
$21,000, compared with approximately $1,122,000 for the third quarter of 1998.
The decrease in 1999 resulted primarily from decreased sales, decreased gross
profit percentage and increased operating expenses, offset in part by decreased
interest expense.

For the nine months ended September 30, 1999 and 1998.

     Net Sales.  Net sales for the nine months ended September 30, 1999
decreased 14.9%, to approximately $26,308,000 compared with approximately
$30,911,000 for the same period in 1998.  This decrease was due primarily to the
decreased sales of the Company's Posi-Track products, offset in part by
increased sales under military contracts.  The decrease is attributable to the
continued transition of selling the Company's Posi-Track products to the
Caterpillar dealer network and production delays related to the model 4810 Posi-
Track as discussed above.   The Company had increased net sales of specially
equipped Posi-Tracks of approximately $2,365,000 related to military contracts
during the nine months ended September 30, 1999.

     Gross Profit.  Gross profit for the nine months ended September 30, 1999
was approximately $6,242,000, or 23.7% of net sales compared with approximately
$7,623,000, or 24.7% of net sales, for the nine months ended September 30, 1998.
The decreased gross profit was due to decreased sales and a lower gross profit
percentage for 1999.  The decreased gross profit percentage in 1999 was due
primarily to the production inefficiencies experienced during the start up of
production of the model 4810 Posi-Track and the lower than average gross profit
realized on the military contracts as discussed above.

     Selling, General and Administrative Expenses.  Selling, general and
administrative expenses increased from approximately $2,584,000, or 8.4% of net
sales for the nine months ended September 30, 1998, to approximately $3,754,000,
or 14.3% of net sales, for the nine months ended September 30, 1999. The
increased dollar volume was due to increased marketing costs, including dealer
start up costs, as well as training and market development costs.  In addition,
the Company experienced increased compensation costs as sales and administrative
personnel have been added to support expanded sales and customer service roles.
In particular, the commission paid to Caterpillar Inc. accounted for slightly
over one-half of the increase in selling, general administrative expenses. The
combination of increased expenses and decreased sales resulted in an increase in
the percentage of selling, general and administrative expenses when expressed as
a percent of net sales.

     Research and Development.  Research and development expenses increased from
approximately $280,000 in 1998 to approximately $412,000 in 1999.  The increase
was due mainly to the development of the model 4810 Posi-Track which went into
production in third quarter 1999, a smaller concept vehicle, and a rubber
tracked agricultural tractor as well as continuing improvements to the Company's
existing models.

     Interest Expense.  Interest expense decreased from approximately $384,000
for the nine months ended September 30, 1998 to approximately $189,000 for the
same period in 1999.  The decrease was the net effect of two factors.  First,
the Company's convertible debentures were exchanged for common stock in the
fourth quarter of 1998, eliminating future interest expense on the debentures.
Second, the Company increased its line of credit borrowings during 1999 to fund
operations.

     Net Income.  Net income for the nine months ended September 30, 1999
decreased to approximately $1,359,000 from approximately $2,841,000 for 1998.
The decrease resulted primarily from decreased sales with lower gross profit
percentage and increased operating expenses, offset in part by decreased
interest expense.  In addition, the Company also recorded a $50,000 income tax
benefit for amended income tax returns for prior years.

Liquidity and Capital Resources

     At September 30, 1999, the Company had working capital of approximately
$36,447,000 compared with working capital of approximately $17,416,000 at
December 31, 1998, an increase of approximately $19,031,000. This increase was
due to the sale of common stock and a warrant to Caterpillar Inc. in January
1999 for $18 million.  The Company used these proceeds primarily to reduce its
line of credit and fund current operations. Inventory levels increased 77%
compared with December 31, 1998 due to several reasons.  During the transition
to Caterpillar dealers, the Company chose not to reduce its production levels,
but instead, increased its finished goods, primarily its 2800 and 2810 model
Posi-Tracks.  It is the Company's intent to market these finished units to its
current dealers, as well as additional international Caterpillar dealers. Other
reasons for the inventory increase include the delay in the start of production
of the 4810 Posi-Track, the general increase in inventory needed to begin
production of the new model, the long lead times to purchase certain inventory
items, and the repurchase of certain inventory from current and former dealers.
Accounts receivable increased due to increased sales to governmental agencies
and the offering of extended finance terms to certain dealers.  Accounts payable
increased due to amounts owing to subcontractors for the Company's governmental
agency sales and the general increase in raw materials.

     On October 14, 1998, the Company entered into a Securities Purchase
Agreement (the Agreement) with Caterpillar Inc. (Caterpillar).  The Agreement
was approved by the Company's shareholders on January 28, 1999 and closed
January 29, 1999. Under the terms of the Agreement, Caterpillar acquired, for an
aggregate purchase price of $18,000,000, one million newly issued shares of the
Company's common stock and a warrant to purchase an additional 10,267,127 newly-
issued shares of the Company's common stock at a price of $21.00 per share.
Also under the terms of the Agreement, the Company's board of directors was
increased from eight to ten with the additional two members appointed as
designated by Caterpillar.

     In connection with entering into the Agreement, the Company and Caterpillar
have entered into several ancillary agreements.  These agreements provide the
Company access to Caterpillar's dealer network and also make various management,
financial and engineering resources from Caterpillar available to the Company
following the closing.  One of these agreements is a Marketing Agreement which
provides, among other things, that the Company will pay Caterpillar a commission
equal to 5% of the dealer net price for complete machines and 3% for replacement
parts and Company-branded attachments for all sales made to Caterpillar dealers.
Should the Company manufacture products that are sold under the Caterpillar
brand name, the Company will pay Caterpillar a trademark license fee equal to 3%
of the net sales of these products to Caterpillar dealers.

     It is the intent of the Company and Caterpillar to introduce the Company's
Posi-Track products to Caterpillar's North American dealers as soon as
practicable.  With the signing and announcement of the Agreement with
Caterpillar, certain of the Company's existing, non-Caterpillar dealers have
been hesitant to place orders for the Company's products. Management believes
these dealers are uncertain of their future status as Posi-Track dealers.
Between the time of the announcement of the Caterpillar transaction and
September 1999, approximately 55 dealer locations decided to no longer carry the
Company's products. These 55 locations are comprised of 18 dealers who will no
longer carry the Company's products and two dealers whose Posi-Track trade area
has been reduced.  One dealer whose trade area has been reduced was the
Company's largest customer for 1998.  This dealer accounted for approximately
21% of the Company's net sales in 1998. This dealer is a Caterpillar dealer and
its Posi-Track trade area was reduced as it was selling into the trade area of
approximately nine other Caterpillar dealers.  During that same time period, the
number of Caterpillar dealers selling and servicing the Posi-Track product line
has increased from six to 35, representing dealers in the United States, Canada
and Australia with a total of over 250 locations.  The Company is also actively
pursuing distribution through additional Caterpillar dealers in Australia, as
well as Central and South America.

     The Company believes that since the signing of the Agreement its sales have
decreased due to the factors discussed above, along with several other factors.
First, the Company believes certain Caterpillar dealers were waiting for the
introduction of the model 4810 Posi-Track before placing orders.  The 4810
incorporates more Caterpillar components than any previous Posi-Track and
utilizes a Caterpillar engine.  As of October 31, 1999, the Company had an order
backlog of approximately $2.8 million for the 4810.  The Company believes this
order rate will increase as more dealers and customers are exposed to the 4810.
Second, certain Caterpillar dealers have chosen to wait until they have received
training on the Posi-Track from factory representatives before placing
significant orders.  The Company is continuing the comprehensive training
program it started in the second quarter to educate the Caterpillar dealers on
the Posi-Track's unique undercarriage. In connection with that program, ASV
increased its number of technical field reps in the third quarter.  These field
reps will provide training and support to ASV's dealers on an ongoing basis.
Third, the Company believes certain Caterpillar dealers are waiting to place
orders until non-Caterpillar Posi-Track dealers are no longer carrying the
Company's products in that
<PAGE>

Caterpillar dealer's trade area. The Company is working with these dealers to
provide a smooth transition to the Caterpillar dealer network. Finally, the
Company believes certain Caterpillar dealers were waiting to place orders until
they could utilize Caterpillar's computer system to order Posi-Tracks. In the
third quarter, the interface between ASV and Caterpillar's computer system was
completed. This interface will allow Caterpillar dealers to order ASV Posi-
Tracks and parts, as well as process warranty claims, on-line in the same manner
they do for Caterpillar products. The Company believes the slow-down in sales is
temporary and expects the order level to increase as additional Caterpillar
dealers receive training and begin carrying the Posi-Track models.

     In connection with the decision of certain of the Company's independent
dealers to no longer carry the Posi-Track product line, the Company has made
arrangements with certain of these dealers to repurchase their existing
inventory of Posi-Track products and transfer it to the new Caterpillar dealers.
In some instances, it has been necessary for the Company to take possession of
the inventory, rather than transferring it directly to the new Caterpillar
dealer.  In these situations, the Company will be responsible for re-marketing
this inventory.  The Company does not currently anticipate a material loss from
the re-marketing of this inventory.

     As a result of the transaction with Caterpillar, the Company's near term
net sales, profitability and other financial results are expected to be lower
than if the transaction were not entered into.  The decline is related to a
number of factors, including (i) the commission to be paid to Caterpillar for
sales made to Caterpillar dealers, (ii) start up, training and market
development costs related to new dealers (iii) transition issues affecting
orders from the preexisting non-Caterpillar affiliated dealers, and (iv) certain
other costs of implementing the transaction and the ancillary agreements.  Over
the longer term, however, management believes that the Company will be able to
achieve improved financial results due to the transaction, including the
ancillary agreements.

     The Company believes its existing cash and marketable securities, together
with cash expected to be provided by operations and available credit lines, will
satisfy the Company's projected working capital needs and other cash
requirements for at least the next twelve months. However, should the Company
find it necessary to offer extended terms on the sale of a large percentage of
its products, the Company may need to finance the related accounts receivable
from these sales.  The Company believes it can obtain this financing, although
it cannot be guaranteed.

     Impact of the Year 2000 Issue. The Company has established a team to assess
and address the possible exposures related to the Year 2000 ("Y2K") issue.  The
areas under investigation include business computer systems, production
equipment, vendor readiness and contingency plans.  The Company does not use
internally developed computer software and is therefore not anticipating major
reprogramming efforts.  The Company's primary financial and operational system
has been assessed and is certified Y2K compliant.  The Company is currently in
the process of upgrading to Y2K compliant versions of several ancillary
applications that are not currently Y2K compliant, the cost of which is not
expected to be material. The majority of the Company's personal computers are
currently Y2K compliant.  Those computers that are not currently Y2K compliant
are in the process of being replaced as part of the Company's technology update
strategy. None of these replacements have been accelerated in response to the
Y2K issue and are not anticipated to have a material effect on the Company's
consolidated financial statements. Equipment used for production or quality
control does not use dates to control operations. The costs of this examination
and upgrading to date have been expensed as incurred and have totaled less than
$5,000.

     The Company believes its most significant year 2000 risk relates to year
2000 compliance of the Company's suppliers and customers, particularly because
the Company is dependent on third party suppliers for certain components of its
products. The Company has mailed questionnaires to its significant vendors to
determine the extent to which the Company may be vulnerable to those third
parties' failure to remedy their own Y2K issues. The Company has reviewed and
evaluated the responses to the returned questionnaires and believes its major
vendors are Y2K compliant.  The Company does not expect it will need to seek new
vendors for its major production components as a result of Y2K noncompliance.
However, there can be no assurance that the year 2000 issue will be properly
addressed by customers, vendors and other third parties.  The efforts of third
parties are not within the Company's control, and their failure to remedy year
2000 issues successfully could result in business disruption, loss of net sales
and increased operating costs.

     Although the Company does not at this time expect a significant impact on
its consolidated financial position, results of operations and cash flows, there
can be no assurance that the systems of other companies will be converted on a
timely basis and will not have a corresponding adverse effect on the Company.

     The statements set forth above under "Liquidity and Capital Resources" in
this Form 10-Q which are not historical facts are forward-looking statements
including the statements regarding ASV's future order rate for its model 4810
Posi-
<PAGE>

Track, the Company's expected net sales, profitability and other financial
results in 1999 and beyond, the Company's capital needs and the impact of and
the Company's plans with respect to the year 2000.  These forward-looking
statements involve risks and uncertainties, many of which are outside the
Company's control and, accordingly, actual results may differ materially.
Factors that might cause such a difference include, but are not limited to, lack
of market acceptance of new or existing products, inability to attract new
dealers for the Company's products, unexpected delays in obtaining raw
materials, unexpected delays in the manufacturing process, unexpected additional
expenses or operating losses, the activities of competitors or the failure of
the Company or third parties to adequately address issues relating to the Year
2000.  Additional factors include the Company's ability to realize the
anticipated benefits from the relationship with Caterpillar and the factors set
forth in the Risk Factors filed as Exhibit 99 to the Company's Report on Form
10-Q for the three months ended June 30, 1999. Any forward-looking statements
provided from time-to-time by the Company represent only management's then-best
current estimate of future results or trends.

     ITEM 3.    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

     The Company has no history of, and does not anticipate in the future,
investing in derivative financial instruments, derivative commodity instruments
or other such financial instruments.  Transactions with international customers
are entered into in US dollars, precluding the need for foreign currency hedges.
Additionally, the Company invests in money market funds and fixed rate U.S.
government and corporate obligations, which experience minimal volatility.
Thus, the exposure to market risk is not material.
