Crop Harvesting, Primarily by Machine (NAICS 115113) — An Investor's Primer

1. Overview

When a wheat farmer in Kansas or a cotton grower in Texas doesn't own a combine, doesn't want to tie up $400,000 to $1,000,000-plus in a machine used only a few weeks a year, or simply can't cover all their acres before the weather turns, they hire someone to bring the machine and cut the crop for them. That hired service — mechanically harvesting, picking, combining, mowing, and baling crops using equipment the service provider owns — is North American Industry Classification System (NAICS) code 115113, "Crop Harvesting, Primarily by Machine." [1] Its most visible practitioners are the itinerant "custom cutters," crews who follow the ripening grain north from Texas to the Canadian border each summer. [7][19]

This is a small, seasonal, equipment-heavy service niche — not a crop-producing industry, and not a place you find pure-play public stocks. It is overwhelmingly a private, family-owned, sole-proprietor business (the official count badly understates it; see Section 3). For a public-market investor, exposure is therefore indirect — through the equipment makers whose combines these operators buy and the diversified agricultural-services names that touch the same customers. For a private investor or operator, this is a real, ownable small business: you buy iron, hire (or import) skilled operators, and sell machine-hours by the acre.

The best operators combine high equipment utilization, reliable crews, strong farmer relationships, and geographic or crop diversification. The weakest are overleveraged, dependent on a single harvest window, or exposed to labor and weather disruption.

2. What it is and how it's structured

Scope. NAICS 115113 covers establishments that provide the machine and the service together: combining grain; machine-picking cotton, fruit, berries, nuts, and vegetables; mechanically harvesting peanuts, sugar beets, and sugarcane; hay mowing, raking, baling, and chopping; silo filling and threshing. The defining feature in the federal definition is that "the machinery used is provided by the servicing establishment." [1]

What it explicitly excludes (and where those activities live instead):

• Providing people for hand-harvesting without the machinery — NAICS 115115, Farm Labor Contractors and Crew Leaders. [1]
• Arranging or contracting harvest as part of managing a farm — NAICS 115116, Farm Management Services. [1]
• Cotton ginning — NAICS 115111. [1]
• Soil preparation, planting, and cultivating services — NAICS 115112. [1]
• Post-harvest crop activities (drying, cleaning, sorting, grading, cold storage) — NAICS 115114. [1]
• A farmer harvesting their own crop is farming (NAICS 111), not this service industry. When a farmer with idle capacity cuts a neighbor's field on the side, that "customwork" income often never surfaces as a distinct 115113 business — a key reason the official establishment count is so small (see Section 3).

Ownership mix. Family-owned and sole-proprietor operators dominate; the industry is small and fragmented, with no company anywhere near a controlling share. [6] Many operators are mixed businesses: a farm may also do custom harvesting, and a harvesting contractor may add planting, hauling, baling, or forage work — classification follows the establishment's primary activity. A crew may run anywhere from one combine to sixty. [7] The trade association, U.S. Custom Harvesters, Inc. (USCHI), founded in 1983, is the closest thing to an industry hub, linking crews with farmers and lobbying on labor and transport rules. [8]

3. How big it is

Our federal figures (employer establishments only). According to the U.S. Census Bureau's County Business Patterns (CBP) for 2023, NAICS 115113 comprised: [2]

The U.S. Small Business Administration (SBA) sets the size standard for this industry at $13.5 million in average annual receipts — below that, a firm counts as "small" for federal contracting and program eligibility. It is a threshold, not an estimate of typical company revenue, and essentially the entire industry sits under it. [3]

What the numbers do not tell you. CBP measures employer establishments, employment, and payroll — not industry revenue, profit, equipment assets, acreage harvested, or market share. Those figures are not published for this code in our source data, and should not be inferred from payroll; we don't state them. [2]

The undercount — and it is enormous here. CBP counts only employer establishments filed under this specific code, which badly understates the real footprint for three structural reasons: most custom operators are sole proprietors or nonemployer businesses (family crews with no year-round W-2 payroll), which CBP excludes by design; many are farmers doing customwork on the side, captured under crop-production codes (NAICS 111) rather than as 115113 firms; and seasonal crews lean on temporary and H-2A visa labor rather than permanent employees. [4]

The scale of the actual machine-for-hire economy shows up on the buyer's side of the ledger. In the USDA's (U.S. Department of Agriculture) 2022 Census of Agriculture, U.S. farms reported spending $10.05 billion on "customwork and custom hauling" — 391,283 farms paying for it, about 2.4% of all farm production expenses — up from $7.56 billion in 2017. [5] That line bundles in custom hauling (trucking) and other custom services, so it overstates machine-harvesting alone; but the gap between it and CBP's ~$206 million of employer payroll is the point. Paying someone to run a machine over your field is a multi-billion-dollar activity that the 338-establishment employer count barely registers. Treat the CBP numbers as the tip; the real industry is a dispersed web of small operators and farmer-to-farmer arrangements.

For a wider frame, industry researcher IBISWorld pegs the broader "Farm Management & Crop Services" grouping — which includes machine harvesting alongside soil prep and other support services — at about $32.4 billion of revenue in 2025, highly fragmented with no firm above roughly 5% share. That grouping is much larger than 115113 alone, so read it as context, not a market size for this code. [6]

4. The investable universe

There is no meaningful pure-play public company in custom crop harvesting; the activity is private, small-scale, and fragmented. [6][26] Public-market exposure is therefore indirect — you own the pick-and-shovel suppliers, not the harvesters themselves. Tickers and prices below are provided only to locate the securities, not as recommendations.

These names benefit when farmers and custom operators replace or upgrade equipment, but their earnings are driven by global equipment cycles, financing, dealer inventory, and manufacturing — not custom-harvesting fees. Their valuations should not be used as direct benchmarks for a private harvester.

Private players. More direct exposure is available but requires proprietary diligence. Representative operators — examples, not a ranking — include Parker Harvesting, a multigenerational Kansas custom harvester; Friesen Harvesting, a family grain-harvesting business working across the Great Plains; and Jay Procter Farms, a Texas farm and custom-forage operator. [24] On the equipment side, CLAAS is a large, family-owned German combine maker with North American production. [25] None is a security you can buy on an exchange; they are businesses you would acquire, finance, or build. No authoritative national league table of custom-harvesting companies exists.

Bottom line: to "invest in custom harvesting" through the stock market is really to bet on farm capital-expenditure cycles via the equipment names. To invest in the service itself, you go private.

5. How the money works

The unit of sale is machine-hours converted into acres. Operators price work several ways — a flat rate per acre, a per-bale or per-unit price, an hourly rate, a share of the crop (a percentage of the grain harvested), or a bundled harvesting-plus-hauling package. [7][10] Grain harvesting is usually per-acre, often with add-ons: an extra per-bushel charge above a yield threshold (heavier crops take more time and fuel) and a separate hauling charge to move grain to the elevator or bin.

Recent per-acre rates from state extension surveys give the revenue line: combining corn averaged roughly $42–$48 per acre in 2024 (Iowa about $44, irrigated Nebraska about $48), and wheat around $32 per acre in Kansas. [10]

Against that revenue, the cost stack is what makes or breaks an operator:

• The machine. A self-propelled combine runs from roughly $400,000 to well over $1,000,000 new, and a header adds more. [12] Because it is used only weeks per year, utilization — acres cut per season per machine — is the single most important economic lever. Extension analyses put a farmer's own variable cost of combining at only about $12–$25 per acre (fuel, repairs, labor), below the typical custom rate — which is why custom hiring is a scale decision: small farms (under ~500 acres) usually hire; large operations (1,500+ acres) usually justify owning. The custom operator's edge is spreading that six-figure machine over many farms' acres. [11]
• Fuel and repairs. A variable field cost of roughly $20–$25 per acre; diesel-price swings hit margins directly. [11]
• Labor. Skilled combine operators are scarce and increasingly imported under the H-2A temporary-worker visa, whose mandated Adverse Effect Wage Rate (AEWR) ran from about $14.83 to $22.23 an hour across states in 2025 (national Farm Labor Survey average about $17.74), and has more than doubled over two decades. [14]
• Financing. With machines costing what a house costs, interest rates on equipment loans and leases are a real line item; higher-for-longer rates raise the ownership hurdle for farmers (good for custom demand) but also raise operators' own carrying costs.
• Travel and logistics. Itinerant crews absorb fuel, permits, lodging, grain carts, trucks, and dead-mileage moving hundreds of machine-miles up the harvest trail. [7][19]

The profit engine, in one line: buy expensive iron, keep it running across as many acres and as many farms as possible in a short season, and price the acre above your variable cost while your fixed cost per acre falls with volume. Weather that compresses the harvest window is the enemy of utilization; a long, dry, staggered ripening season is the friend. Metrics that matter for diligence: contracted and harvested acres, acres per machine-day, realized price versus all-in cost per acre, equipment uptime, labor retention, customer concentration, fleet age and debt service, and how much off-season work (planting, forage, baling, hauling) absorbs fixed costs. If you use Earnings Before Interest, Taxes, Depreciation, and Amortization (EBITDA), normalize it for owner labor, deferred maintenance, and unusually strong harvest conditions.

6. What drives demand

Demand for hired harvesting follows physical acres, crop mix, harvest timing, and how many farms are willing to outsource machinery-intensive work:

• Planted acreage and yields. More acres and bigger crops mean more machine-hours to hire. USDA's National Agricultural Statistics Service (NASS) estimated 2026 U.S. plantings of 95.3 million acres of corn, 85.4 million of soybeans, 42.7 million of wheat, and 9.85 million of cotton, with corn-for-grain harvest area of 87.4 million acres and soybean harvest area of 84.4 million. These are demand indicators, not the size of NAICS 115113. [9] The long-run headwind is structural: wheat acreage sits near historic lows, squeezing the wheat-harvest circuit that historically defined the business. [13]
• The own-vs-hire decision. Set by farm size, combine prices, and interest rates. Rising machine prices and financing costs push more farmers toward hiring; falling ones pull the other way. [11][12]
• Farm income and crop prices. When corn, wheat, and cotton prices are soft (as in 2025), farmers cut discretionary spend and negotiate harder on custom rates, pressuring operator margins. Strong prices can also cut the other way — flush large farms may buy their own iron. [6]
• Labor availability. Fewer domestic operators and reliance on H-2A make labor supply — and its cost — a demand-shaping constraint. [14]
• Weather and timing. Compressed or overlapping windows (corn and soybeans ripening in the same short fall stretch) create acute, hard-to-serve demand spikes that a shrinking pool of crews struggles to cover. [13]
• Technology. Automation, telematics, sensors, and precision systems can raise throughput and reduce the number of operators a fleet needs. [20][22]

7. Regulation

Custom harvesting is lightly regulated as an activity — there is no dedicated licensing regime — but it sits at the intersection of several federal regimes:

• Labor / immigration. The H-2A visa program (administered by the U.S. Department of Labor, DOL) lets employers facing seasonal shortages hire temporary foreign agricultural workers, subject to certification, recruitment, wage, housing, and transport requirements; employers must pay the AEWR. A significant methodology change took effect October 2, 2025, shifting AEWR wage-setting from the Farm Labor Survey (FLS) toward Bureau of Labor Statistics Occupational Employment and Wage Statistics (OEWS) data — a change that alters, and in many places is expected to lower, mandated wages, directly affecting operator labor cost. [14]
• Worker safety. Occupational Safety and Health Administration (OSHA) agricultural standards (29 CFR 1928) cover equipment and field operations; field-sanitation rules apply when an agricultural establishment has at least 11 employees engaged in hand-labor in the field, so their relevance varies by crop and work process. [16]
• Transportation. Crews moving oversize combines and support vehicles across state lines deal with commercial-driver, permitting, weight, and hours-of-service rules. Federal Motor Carrier Safety Administration (FMCSA) hours-of-service exemptions can apply to agricultural-commodity transport within a 150-air-mile radius during state-defined planting and harvesting periods — but a for-hire custom operation should not assume it qualifies as a "covered farm vehicle." USCHI advocacy has long focused on these agricultural exemptions. [8][17]
• Emissions. Environmental Protection Agency (EPA) standards apply to the nonroad diesel engines used in tractors, combines, and other agricultural equipment. [18]
• Pesticides. The EPA's Agricultural Worker Protection Standard (WPS) can affect harvest crews working on farms where pesticide applications, restricted-entry intervals, or contaminated equipment are in play. [18]

State rules on wage-and-hour, workers' compensation, commercial-driver licensing, vehicle weights, road permits, and environmental compliance can materially change operating costs.

8. Competitive dynamics and consolidation

This is a fragmented, low-concentration industry — no player holds meaningful share, and the SBA size standard tells you the ceiling for a "small" firm sits above almost everyone in it. [3][6] Competition is local and relationship-driven: custom harvesters tend to work the same farms year after year, so reputation, dependable equipment and mechanics, the ability to move quickly between regions, and simply showing up when the crop is ready matter more than price alone. [7] Competition comes from other custom operators, large farms harvesting in-house, farm-management companies, cooperatives, and dealers offering rentals or used machinery.

The structural story is contraction, not roll-up. Declining wheat acreage, an aging operator base, rising machine and labor costs, and rural depopulation have thinned the ranks of custom cutters, with trade coverage repeatedly framing the classic "wheatie" circuit as struggling to stay relevant. [13] Zoom out to the broader ag support sector and the pattern is scale-up-by-attrition: USDA's Economic Research Service (ERS) reports that inflation-adjusted receipts for agricultural services rose 263% between 1978 and 2022 while the number of active establishments fell 10% — bigger businesses, fewer of them (that figure covers the broad support sector, not 115113 specifically). [15]

There is little evidence of financial-buyer consolidation in custom harvesting itself; the barriers that keep it fragmented (seasonal, capital-heavy, labor-constrained, geographically dispersed) also keep it unattractive to a one-size-fits-all national roll-up. The more likely long-run path is selective, regional consolidation — fewer, larger, more mechanized crews serving more acres each, adding fleets, mechanics, and succession solutions — rather than a single scale player.

9. Risks

• Utilization / operating leverage. This is the dominant operating risk: a short or weather-disrupted season leaves six-figure machines idle while equipment and labor costs still come due; fixed cost per acre spikes. [12]
• Commodity-price and farm-income cycles. Weak crop prices compress what farmers will pay for custom work and can push marginal operators out. [6][13]
• Labor cost and availability. Dependence on scarce skilled operators and H-2A labor exposes operators to wage-rule changes and visa-processing friction. [14]
• Input and capital costs. Diesel volatility, equipment-price inflation, and interest rates all hit margins and the own-vs-hire calculus. [11][12]
• Secular acreage decline in the crops (notably wheat) that anchor the traditional harvest circuit. [13]
• Concentration and collections risk for any single operator whose book is a handful of repeat farms.
• Operational hazards — machinery breakdowns at peak season, fires, dust, road-transport accidents, and liability claims.
• For public-market investors, diffusion risk: with no pure play, the "custom harvesting" thesis is really a farm-capex thesis expressed through equipment makers whose fortunes also depend on tractors, tillage, precision ag, and global markets — the link to custom harvesting specifically is loose. [26]

10. How to invest, and the outlook

Public-market routes (indirect). There is no listed custom-harvesting company, so exposure runs through the equipment supply chain — Deere (DE), CNH Industrial (CNH), AGCO (AGCO), Kubota (KUBTY), the equipment-distribution proxy Titan Machinery (TITN), plus diversified The Andersons (ANDE) and micro-cap Art's-Way (ARTW). [26] A broad agricultural-equipment or ag-sector fund captures the same driver — farm capital spending — with diversification. Analyze these as cyclical industrials: equipment orders, parts-and-service revenue, dealer inventory, financing losses, net farm income, crop prices, and the replacement cycle for big iron — not custom-harvesting margins as such.

Private routes (direct). This is fundamentally a private operating business. The realistic ways in are to buy or start a custom-harvesting operation (acquiring the machines, customer relationships, and crew — ideally from an aging owner with strong repeat farms), to finance or lease equipment (combines, forage harvesters, trucks, grain carts) to operators, to fund fleet upgrades tied to contracted acres, or to build a regional platform around shared mechanics, purchasing, dispatch, and logistics. USCHI membership and the used-combine market are the practical entry points. Diligence should prioritize normalized utilization, customer concentration, equipment condition, debt maturities, repair history, booked acres, labor arrangements, insurance, environmental compliance, and succession plans. [8]

Near-term outlook (forward-looking judgment). The reported backdrop is soft: low crop prices and a farm-income squeeze into 2025–2026, wheat acreage near historic lows, and a shrinking, aging operator base. [6][13] Set against that, a few forces plausibly support the hiring side even as the number of operators falls: combine prices well into six and seven figures plus elevated financing costs keep raising the bar for farmers to own, pushing work toward custom crews; and the October 2025 shift in H-2A wage methodology could relieve some labor cost for operators who use the program. [12][14] The most likely shape of the industry — analyst judgment, not reported fact — is consolidation by attrition: fewer, larger, more mechanized crews covering more acres, serving a farm economy that still needs the machine-hours even as fewer people want to supply them. The strongest operators will be those with high uptime, disciplined financing, multi-crop or multi-region capacity, and enough off-season work to cover fixed costs. For public-market investors, the cleanest expression remains the equipment ecosystem; the service itself stays a private, localized, diligence-intensive operator's game.
