Agricultural & Farm Equipment Appraisal
Tractors, implements, irrigation infrastructure and full equipment lines — valued to a stated premise, for a stated user, on a stated date.
Why the premise decides the number
The single most common defect in farm equipment valuation is not a wrong model year or a missed hour meter. It is a report that never says which premise of value it used, or uses one premise while the reader assumes another. The same tractor, in the same condition, on the same day, carries four defensible and materially different numbers depending on what is being assumed about the sale.
| Premise of value | What it assumes | Who asks for it |
|---|---|---|
| Fair market value in continued use | The asset keeps working where it stands, as part of an operating whole. Includes transportation and installation. | Going-concern sale, buy-sell, some insurance |
| Fair market value installed | The asset is valued in place, considering market conditions for that asset, but independent of the earnings of the business around it. | Purchase price allocation, property tax, insurance |
| Orderly liquidation value | A liquidation sale with a reasonable period to find buyers. Seller is compelled to sell; assets go as-is, where-is. | Secured lenders, Chapter 11, workout |
| Forced liquidation value | A properly advertised public sale under distressed conditions and with a sense of immediacy. Buyer bears removal and transport. | Chapter 7, foreclosure, auction |
Condition matters. But across a real equipment line, the spread produced by changing the premise is routinely wider than the spread produced by changing the condition grade, because the premise changes who the buyer is, how long they have, and who pays to get the machine off the property.
A worked example
Illustrative arithmetic, not market data. The figures below are invented to show the mechanism. They are not a price list, not a quotation, and not evidence of what any particular machine is worth. A real conclusion comes from researched market evidence for the specific asset on the specific date.
| Premise | Illustrative figure | What changed |
|---|---|---|
| Fair market value in continued use | $100,000 | Baseline. Machine stays in the operation; transport and install included. |
| Fair market value installed | $88,000 | Still valued in place, but detached from the earnings of the farm around it. |
| Orderly liquidation value | $62,000 | Compelled sale, reasonable marketing period, as-is where-is, buyer removes. |
| Forced liquidation value | $41,000 | Distressed sale with immediacy. Fewer bidders, buyer bears removal. |
A ~59% spread across premises on one unchanged machine. Move the condition grade one step instead and the movement is typically far smaller. This is why the engagement letter has to fix the premise before the research starts, not after.
Read the table the other way and the practical point appears: a lender who asks for “the value” and receives fair market value in continued use has been handed a number that will not survive the day they need to act on it. That is not the appraiser being clever; it is the premise doing exactly what it says.
Auction evidence versus dealer asking prices
Two sources of market data are available for farm equipment, and they are not interchangeable.
| Auction results | Dealer asking prices | |
|---|---|---|
| What it is | Completed transactions at public sale | Offers to sell, before negotiation |
| Records | Price achieved, date, location, hours, condition notes | Asking price, specification, dealer location |
| Bias | Reflects a compelled or time-bound seller | Reflects the seller's hope, and often includes reconditioning and warranty |
| Best used for | Liquidation premises; establishing a floor | Continued-use and installed premises, adjusted downward for the spread |
Neither is 'the' market. A report that uses only dealer listings will overstate a liquidation conclusion; one that uses only auction results will understate a continued-use conclusion.
The honest method is to use both and to say which carried the conclusion and why. Where auction comparables are thin for a specific implement — which happens constantly with specialised or older equipment — the report says so and explains what was relied upon instead, rather than presenting a thin sample as though it were a deep one.
Irrigation infrastructure: the item handled worst
Irrigation is where farm equipment appraisals most often go wrong, because it sits on the boundary between equipment and real property improvement. Wells, pumps, mainline, pivots and drip systems can be valued as removable equipment or as an installed component of the property, and the two produce materially different numbers.
The question is not aesthetic. It determines whether the asset belongs in a personal property schedule at all, whether it travels with a sale, and whether a secured lender's filing actually attaches to it. Where the answer is genuinely ambiguous the report states the ambiguity, values on the stated assumption, and discloses that the conclusion moves if the assumption is wrong.
In Arizona this is not a marginal issue. Yuma County alone farms roughly 230,000 acres, all of it irrigated with Colorado River water delivered through seven irrigation districts, and USDA's 2022 Census of Agriculture put the county's agriculture at about $1.3 billion in direct sales. Irrigation is not an accessory in that setting; it is the productive asset.
The Pinal County corridor
The corridor between the two metros is where Arizona agricultural equipment work concentrates, and it is changing underneath the farms. Casa Grande now hosts vehicle manufacturing at scale, and Pinal County has projected tens of millions in tax revenue to the city and county over the facility's first two decades. Industrial and distribution development follows that kind of anchor.
For valuation the consequence is specific rather than general. Land in transition carries equipment in transition: an operation that is winding down agricultural use and selling into a market where the buyers are no longer farmers is a different assignment from one replacing a tractor. The buyer pool determines the premise, and in a converting corridor the buyer pool is the thing that has moved.
It also affects classification. Agricultural land moving toward commercial use can hold a classification on the assessor's roll that no longer matches what happens on it, and classification is appealable on the same clock as value. That is a real-property question rather than an equipment one, but it arrives in the same conversation often enough to be worth flagging.
What is needed to do the work
The quality of the conclusion is mostly decided before any research starts, by how complete the asset information is. For an equipment line that means:
| What | Why it matters | If it is missing |
|---|---|---|
| Year, make, model and serial for each unit | Identifies the exact configuration; serial ties to build specification | The unit is valued on a stated assumption about specification, disclosed |
| Hour or acre meter readings | The primary condition proxy buyers price against | Condition is assessed on inspection alone and the report says so |
| Attachments and implements, listed separately | They frequently carry value independent of the prime mover | Risk of them being absorbed into a single figure and effectively lost |
| Maintenance records where they exist | Distinguishes a well-kept machine from a superficially similar one | Not fatal; the absence is noted rather than assumed either way |
| Whether items are owned, leased or financed | A leased unit is not the owner's asset to sell or pledge | Must be resolved before the schedule can be relied upon |
Blanks are better than guesses. An honest “not known” on a serial number produces a disclosed assumption; an invented one produces a report that is wrong in a way nobody can see.
Who orders these, and what the report has to carry
| Who orders it | Why | Premise usually required |
|---|---|---|
| Agricultural lender | New facility, annual review, collateral monitoring | Orderly liquidation, sometimes forced |
| Chapter 7 or 11 trustee | Schedules, sale motion, adequate protection | Orderly or forced liquidation |
| Seller or buyer | Whole-farm or line sale, partnership exit | Fair market value in continued use |
| Insurer or insured | Scheduling, or proving a loss after the fact | Installed, or replacement cost depending on policy |
| Court | Dissolution, partnership dispute, damages | Set by the matter, not by preference |
Machinery and equipment is personal property, so development is governed by USPAP Standard 7 and reporting by Standard 8. In practice that means the report must identify the client and any other intended users, state the intended use, state the type and definition of value with its source, state the effective date, describe the scope of work performed, and disclose any extraordinary assumptions or hypothetical conditions relied upon. A report that omits the definition of value has not merely been informal; it has left out the thing that makes the number mean something.
Where an element does not apply — a cost approach on a line of twenty-year-old implements, for instance, where reproduction cost tells you nothing a buyer would pay for — the report says the approach was considered and explains why it was not developed. Silence and dismissal are not the same thing.
Where this sits
Agricultural equipment is one lane inside machinery & equipment valuation, which is itself a personal property discipline. Lenders taking equipment as security will also want loan collateral work; trustees and counsel will more often be looking at bankruptcy or litigation support. If the assignment is a whole-business sale rather than an equipment line, the question is probably a business valuation one. Lending institutions may prefer to start at what we do for banks and lenders.

What the work actually looks like
Real assignments, client details removed — what each engagement actually turned on, rather than how it felt.
A house, a workshop of machine tools, a forty-year firearms collection and a stake in the family company — four disciplines that three appraisers had only partly covered. One engagement, one effective date, one set of assumptions.
A donation the regulations would have aggregated past the appraisal threshold, which the donor had assessed item by item. One qualified appraisal covering the group, itemized, signed inside the window the regulations allow.
An opposing report whose number was not obviously wrong — which is what made it dangerous. It failed on its own certification, and was answered section by section with an independent valuation to the correct definition of value.
