Wheat Combine Harvester: History, Sizes and Costs

A wheat combine harvester cuts the crop, threshes the grain from the heads, cleans it and stores it in a tank, all in one pass. New large combines are expensive: the 2026/2027 Manitoba machinery guide uses purchase prices of CAD 600,000 for a Class 6 rotary combine up to CAD 1,150,000 for the largest class, and University of Illinois cost estimates used a $741,000 list price for a new combine in 2023.

This guide covers how the machine works, how it grew from a 20-horse prototype into today’s 700-plus horsepower models, which models sell for what at auction, and what custom hire charges. It includes dated price data from extension services and auctions, three charts and a calculator that gives a rough example estimate of a used combine’s value on your own numbers.

Wheat combine harvester sizes at a glance

Combines are grouped into classes by engine power. The table uses the classes and purchase prices from the Manitoba government’s farm machinery cost guide, plus its custom rate per acre. Prices are guide values in Canadian dollars for 2026/2027, not dealer quotes, and the guide prices exclude the header.

How a wheat combine harvester works

The name comes from combining three jobs that once needed separate machines and crews: reaping, threshing and winnowing. A modern machine does them in this order.

• Header: a cutter bar and reel cut the standing wheat and feed it to the centre. Draper and flex headers are common in wheat.
• Feeder house: a chain conveyor carries the cut crop up into the machine.
• Threshing: a rotor or a drum rubs the grain out of the heads. Rotary machines use one or two long rotors; conventional machines use a cylinder and straw walkers.
• Cleaning: sieves and a fan blow chaff away and let clean grain fall through.
• Grain tank and unloading auger: clean grain goes to the tank and is unloaded into a grain cart or truck.
• Residue: straw and chaff are chopped and spread, or dropped in a row for baling.

Settings matter more in wheat than many growers expect. Rotor speed, concave clearance, fan speed and sieve openings all change how much grain is lost out the back and how much is cracked. Operators check losses behind the machine and adjust as moisture changes through the day.

From horse teams to self-propelled machines: a short history

The first combine harvester is credited to Hiram Moore in Michigan. He built and patented a machine in the 1830s that reaped, threshed and winnowed grain, and his full-scale version was pulled by about 20 horses, according to the history summary of the combine harvester.

By the early 1900s, horse-drawn combines worked the wheat plains of the American West, often with teams of 20 or more horses. Self-propelled machines followed: Holt Manufacturing in California built one in 1911, and in 1937 Thomas Carroll, working for Massey-Harris in Canada, perfected a self-propelled model that the company sold widely from 1940. In Europe, Claeys launched a self-propelled combine in 1952 and Claas followed in 1953.

Later decades brought rotary threshing, enclosed cabs, yield monitors and GPS steering. Engine power kept climbing. The Case IH AF11, for example, is listed at 775 horsepower with a 567-bushel grain tank on the Case IH AF11 product page (checked October 2026).

Vintage combine harvesters today

Old combines have a second life with collectors, museums and farm shows. Restored machines show visitors how harvest moved from crews of workers to one operator in a cab.

Vintage machines also sell at auction. In July 2026, Machinery Pete previewed an upcoming vintage tractor auction in Penfield, Illinois, featuring 1970s Massey Ferguson models; the auctioneer said he had never turned down so many pieces of equipment, as reported by AgWeb. Prices for vintage equipment depend on rarity, condition and paint, not on harvest output, so no single price range fits them. If you are buying one to work, check parts supply first.

What a wheat combine harvester costs to buy

Prices depend on size, age, hours and the header. Three kinds of price data are useful, and they measure different things.

• Guide or list prices for new machines. The Manitoba guide values new rotary combines from CAD 600,000 (Class 6) to CAD 1,150,000 (Class 10+) for 2026/2027, header not included. The University of Illinois used a list price of $741,000 for the combine in its 2023 estimate, up from $587,000 in 2021, a 26% rise, according to farmdoc daily (October 2025).
• Auction results for used machines. At a June 30, 2026 auction in Minnesota, a 2024 John Deere S780 with 476 hours sold for $414,000. At another auction the same day in Illinois, a 2013 John Deere S670 with 2,316 engine hours sold for $103,500; the average auction price for that model in 2026 to that date was about $75,125 (AgWeb, July 2026).
• Dealer asking prices. These are often above auction results and can include trade-ins, warranty and financing. Treat them as a starting point for talks.

Used prices move with supply. Machinery Pete said in 2022 that used combine prices had risen over the previous 18 months, as reported by AgWeb in September 2022, and in 2026 he pointed to a shortage of five- to 12-year-old machines pushing buyers toward newer used units.

Why new combine prices rose

New equipment prices rose by more than 20% between 2021 and 2023, the farmdoc daily analysts note. The list price of the combine in their cost model went from $587,000 in 2021 to $741,000 in 2023. Interest rates and diesel prices rose over the same years, which made each machine dearer to finance and run.

Higher new prices push buyers toward used machines. That is one reason late-model used combines have sold for record sums at auction, and why the supply of five- to 12-year-old machines matters so much to price.

What to check on a used wheat combine

Hours alone do not set the price. Buyers look at separator hours, the condition of the rotor, concaves and feeder chain, the header type and width, and whether the yield monitor and guidance are included or need a new subscription. A machine set up for corn may need a new header and concave changes for wheat, which adds to the real price.

The Manitoba guide assumes a combine keeps about one third of its purchase price after a 12-year service life, losing value evenly after the first year, at about 250 separator hours a year. The calculator below uses that rule for a rough first estimate before you compare real auction results.

Owning or hiring a custom harvester

Owning is not the only way to get a wheat crop cut. Custom harvesters bring their own machine, operator and fuel and charge per acre, often with extra per-bushel charges. Survey results from extension services give a sense of the rates for wheat and small grains.

• Texas (2026 survey): the per-acre part of combining and hauling wheat averaged $31.30 across 34 responses, from $20 to $45, plus about $0.28 per bushel for hauling, according to the Texas A&M AgriLife Extension custom rates survey. Some operators add an overage charge on yields above a set level.
• Wisconsin (2025): straight combining of small grains averaged $37.12 per acre, from $25 to $50, and wheat with grain cart and local hauling averaged $48.18, from the University of Wisconsin custom rates report.
• Mississippi (2024 survey): combining wheat averaged $41 per acre across five responses, from $35 to $50, according to Mississippi State University Extension.
• Manitoba (2026/2027 guide): custom rates of CAD 31 to 40 per acre, falling as combine size rises.

Rates vary by region, yield, field size and distance. Survey numbers are averages of reported rates, not quotes. Get written prices from local operators before you decide, and get professional advice on financing and tax before a large purchase.

To put the rate in context, US farmers received $6.23 per bushel for all wheat in August 2026, according to USDA’s Agricultural Prices report (September 2026). At that price, a $35 per acre harvest bill equals about 5.6 bushels of wheat per acre.

How to choose a wheat combine

1. Count your acres. Add wheat to other crops the same machine will harvest. Fewer acres point toward a used machine, shared ownership or custom hire.
2. Check your harvest window. Divide acres by the days you can safely harvest. The Manitoba guide’s work rates (10 to 24 acres an hour by class) help you size the machine.
3. Match the header. Wheat growers often choose a draper header. Header width should suit the combine’s power and your field size and terrain.
4. Compare total cost per acre. Include depreciation, interest, insurance, repairs, fuel and labour, not just the price. Our guide to the cost of a combine covers cost per acre.
5. Inspect used machines. Look at separator hours as well as engine hours, rotor and concave wear, the feeder chain, bearings and service records.
6. Check dealer support. Parts and service close to your farm reduce downtime during a short harvest.

Modern technology on a combine

Most new large combines come with tools that were rare 20 years ago. Common features include GPS auto-steering, yield monitors that record yield and moisture as you drive, automatic header height control, camera or sensor checks on grain quality, and telematics that send machine data to the office. Brands such as John Deere, Case IH, New Holland and Claas each sell their own versions.

Yield maps are useful after harvest. Comparing them with in-season crop maps shows which parts of a field were weak all year and which lost yield late. Some features carry subscription fees, so ask the dealer what is included and for how long.

Smaller combines and plot harvesters

Not every farm needs a Class 8 machine. Smaller and older combines, including Class 5 and below, are common on mixed farms, research plots and hilly ground. They cost less to buy and fit narrow gates and small fields, but they cover fewer acres an hour.

For small acreages, a used mid-size combine or custom hire is often cheaper per acre than a new machine. Our guide to small-scale farming tools covers other equipment for smaller farms.

Using satellite crop maps before harvest

Crop condition maps help plan harvest order. Fields or zones that matured early, or that lodged or ripened unevenly, show up in vegetation index maps in the weeks before harvest. Farmonaut Satellite + AI Farm Monitoring System provides these maps for fields you draw on the web or in the mobile app, and developers can pull the same data through the Farmonaut API and its developer documentation. Satellite maps show crop change, not its cause, so check fields on foot before acting.

How we checked the numbers

We used extension service surveys and cost studies from Illinois, Texas, Wisconsin, Mississippi and Manitoba, USDA price data and auction results reported by AgWeb. Each price is labelled as a guide price, a cost estimate, a survey average or an auction result, with its date. Costs from Illinois are for corn and soybeans, and we say so where we use them. Prices in Canadian dollars are not converted.
