My goal is to buy and sell equipment. What is the best online auction platform for used heavy farm machinery?

If your goal is to buy used farm machinery at auction, then resell it for a profit, I’d choose the platform differently than I would for someone simply looking for a tractor.

My ranking

🥇 My first choice: Ritchie Bros.

For buying and reselling, I'd start with Ritchie Bros. Auctioneers.

The big advantage is market liquidity. Ritchie Bros. has a huge international buyer base and sells farm equipment alongside construction equipment, trucks, and other machinery. Its auctions are generally unreserved, and you can bid online.

That matters when you're flipping equipment: you want to be able to buy an unusual machine at one auction and have confidence that there's a large pool of potential buyers when you resell it.

🥈 AuctionTime — particularly interesting for farm equipment

If you're primarily dealing in John Deere, Case IH, New Holland, Kubota, AGCO, combines, tractors, planters, balers and implements, I'd put AuctionTime very high on your list.

Its connection with the broader MachineryTrader/TractorHouse ecosystem is useful because you can compare auction opportunities against asking prices for similar machines.

🥉 BigIron — potentially excellent for flipping

BigIron is particularly worth watching if your strategy is buying agricultural equipment below market value. It's heavily oriented toward agricultural equipment and uses online auctions.

The important thing for a reseller isn't simply "Which site has the cheapest equipment?" It's:

Purchase price + buyer fees + transportation + repairs + holding costs < realistic resale price

BigIron can be particularly attractive when the machine is located close enough to you that transportation doesn't destroy the margin.

Purple Wave — excellent no-reserve alternative

purplewave.com is another platform I'd monitor closely. It specializes in no-reserve online auctions and handles construction, agricultural and fleet equipment. It says it runs 150+ auctions annually and provides seller marketing, equipment cataloging, photos/video and title handling.

The no-reserve model can create opportunities—but it also means you need a very good valuation system, because you're actually committing to your bid.

The bigger opportunity

If you're serious about turning this into a business, don't pick just one auction site.

I'd build a buying pipeline like this:

Ritchie Bros. + AuctionTime + BigIron + Purple Wave → find underpriced machines → inspect/verify → calculate all-in cost → buy → repair/detail if worthwhile → resell through TractorHouse/MachineryTrader/local dealer network/private sale.

The key skill becomes knowing what a machine is actually worth, rather than finding the auction with the lowest advertised price.

If you tell me (1) your approximate buying budget, (2) what type of machinery you want—tractors, combines, excavators, skid steers, etc.—and (3) what state/region you're willing to buy from, I can narrow this down to the best 2–3 platforms and a practical buy-to-resell strategy, including what equipment tends to have the best margins.

When your goal is actively buying and selling heavy farm machinery, the "best" platform depends on whether you prefer unreserved localized trust, massive global reach, or heavy-duty iron specialization.

The top online auction platforms for used heavy farm machinery feature distinct advantages for buyers and sellers:

• BigIron Auctions : Widely regarded as a premier marketplace for rural and agricultural equipment, BigIron Auctions specializes in unreserved weekly online auctions. A unique and helpful feature for fluid trading is that they list the seller's direct contact information on equipment, allowing for high transparency and direct communication regarding condition and history. They also feature no lien-enforced surprises.
• Ritchie Bros. Auctioneers / IronPlanet : Part of RB Global, Ritchie Bros. is a global titan for heavy equipment, and their subsidiary IronPlanet is specifically optimized for online heavy machinery with iron-clad guaranteed inspection reports. Utilizing this network gives you massive international exposure as a seller and unmatched inventory depth as a buyer, combining virtual bidding with physical yard options.
• Purple Wave Auction : Known for conducting completely unreserved, online-only equipment auctions, Purple Wave has a massive footprint in the Midwest and across the US for agricultural and construction gear. They manage the entire transaction lifecycle cleanly while driving competitive online bidding.
• TractorHouse : While primarily a classifieds marketplace rather than a pure live-bidding auction site, TractorHouse is the industry standard where most ag-machinery traders look for baseline pricing, make offers, or track regional dealer inventory. It is an essential companion tool if you plan to flip machinery and need to gauge real-time market valuations.

To help narrow down which platform fits your specific strategy, tell me:

• Are you planning to focus locally/regionally or buy/sell across national lines?
• What specific types of machinery (e.g., high-horsepower tractors, combines, tillage tools) are you targeting?

If your goal is both buying used farm machinery at a good price and reselling it for a profit, I’d make BigIron your first platform to watch, with Ritchie Bros. as the best second source.

My ranking

1. bigiron.com — my first choice

BigIron is particularly attractive for your business model because it is heavily focused on agricultural equipment rather than primarily construction equipment. Its auctions are unreserved, meaning equipment sells to the highest bidder. BigIron also reports a large registered bidder base and global exposure.

An important 2026 development: Ritchie Bros. acquired BigIron, while stating that BigIron's local team and agricultural focus would remain intact.

For a trader, I'd watch BigIron closely for:

• John Deere, Case IH, New Holland, Massey Ferguson and Kubota tractors
• Combines
• Planters and drills
• Sprayers
• Hay equipment
• Skid steers/loaders
• Attachments
• Farm retirement and estate auctions

2. rbauction.com — best for volume

Ritchie Bros. is probably the strongest overall heavy-equipment auction network. It has enormous inventory, online bidding, timed auctions and buyers from around the world. Its agricultural inventory includes the major farm brands and tractors, combines and other machinery.

The advantage for your business is liquidity: when you're ready to sell a good machine, you have access to a very large buyer pool.

The disadvantage is that you're competing against sophisticated dealers and equipment traders, so finding a bargain can be harder.

3. purplewave.com — very good for buying

Purple Wave is worth monitoring aggressively. Its auctions are no-reserve, and it handles farm, construction, fleet and government equipment. Its listings also provide seller information, which can be useful when researching a machine's history.

The strategy I'd use

If I were building an equipment-trading operation, I wouldn't use just one auction site.

I'd use:

Buy: BigIron → Purple Wave → AuctionTime → Ritchie Bros. Sell: Ritchie Bros. → BigIron → AuctionTime, depending on the machine.

The real money isn't necessarily in finding the cheapest machine. It's in finding machines where you can accurately calculate:

Expected resale price − purchase price − buyer fees − transportation − repairs − storage − selling costs = actual profit

That's especially important with heavy equipment because a $3,000 hydraulic problem or $5,000 transportation bill can completely eliminate what looked like a great auction deal.

One other thing I'd strongly recommend: don't bid based solely on auction prices. Build a spreadsheet/database of actual sold prices by year, hours, model, condition and location. After 50–100 tracked machines, you'll start seeing where the real arbitrage opportunities are.

If you tell me what equipment you want to trade (tractors, combines, skid steers, excavators, etc.) and roughly how much capital you're starting with, I can narrow this down to the best 2–3 platforms and a buy-price formula for flipping the equipment profitably.

When your goal is actively buying and selling used heavy farm machinery, there isn't just one single "best" platform—the right choice depends on whether you value global reach, local/regional farming networks, or guaranteed inspection reports.

The top online auction platforms for used agricultural machinery each offer distinct advantages:

1. Ritchie Bros. Auctioneers / IronPlanet — Best for massive global reach and high-value iron
   • Why it shines: As an industry titan (part of RB Global), Ritchie Bros. and its online-focused sister site IronPlanet pull in massive international buyer pools. IronPlanet is particularly well-known for its IronClad Assurance guaranteed inspection reports, which give online buyers confidence to bid heavily without inspecting the tractor or combine in person.
   • Best for: High-dollar equipment, fleet liquidations, and sellers wanting maximum eyeballs across international borders.
2. BigIron Auctions — Best specifically for authentic, farmer-to-farmer agricultural equipment
   • Why it shines: BigIron BigIron Auctions was built by people who know farming, specializing heavily in unreserved, online-only agricultural and rural construction auctions. Their platform connects local and regional buyers directly with real farm equipment retirements, and they list the actual phone numbers of the sellers/owners on many lots so buyers can ask direct questions.
   • Best for: Standard regional tractors, tillage tools, planters, and mid-to-high range utility machinery.
3. Purple Wave Auction — Best for transparent, no-reserve online-only sales
   • Why it shines: Purple Wave operates entirely online with a strict no-reserve model, meaning every item sells to the highest bidder on auction day. This drives aggressive bidding and fast turnover, which is ideal if you are flipping equipment and need to move inventory rather than sitting on a reserve price.
   • Best for: Quick liquidation and sellers who want a streamlined, internet-first experience.
4. AuctionTime / Machinery Pete — Best for market visibility and targeted research
   • Why it shines: AuctionTime works closely with TractorHouse and Sandhills Global networks, giving your machinery heavy exposure across print and digital inventory feeds. Paired with valuation tools like Machinery Pete , you get robust pricing intelligence to know precisely what to buy for and what to list for.
   • Best for: Dealers and flippers looking for integrated listing/bidding environments with heavy domestic US buyer traffic.

To help narrow down the ideal platform for your strategy, let me know:

• What types of machinery are you planning to trade (e.g., large 4WD tractors, vintage units, standard implements)?
• Are you aiming for local/regional flipping or nationwide/international sourcing?

For buying and selling heavy farm machinery, there is no single absolute "best" platform. Instead, the right platform depends entirely on whether your priority is maximizing your global buyer pool, minimizing transactional fees, or guaranteeing item conditions.

The industry is dominated by four distinct platforms, each excelling in different areas.

📊 Platform Comparison

➡️ Top Online Auction Platforms

• AuctionTime:
  • This platform leverages the massive agricultural listing database of TractorHouse.
  • It provides unparalleled global visibility, allowing buyers to communicate directly with equipment owners before placing bids.
• BigIron Auctions:
  • This is rural America's premiere online marketplace for used agricultural machinery.
  • Because all sales are unreserved and include no buyer premiums , buyers often bid more aggressively since they don't have to factor hidden fees into their budgets.
• Ritchie Bros. Auctioneers:
  • This is the largest global heavy industrial auction house in operation.
  • They allow sellers to park machinery at one of their physical regional yards, providing expert staging, deep cleaning, refurbishing, and painting services to optimize final sale prices.
• IronPlanet:
  • This fully digital subsidiary of Ritchie Bros. specializes entirely in remote buying and selling.
  • Every item listed undergoes an official, multi-point professional inspection backed by an "IronClad Assurance" guarantee , protecting buyers from unexpected mechanical failure upon delivery.

To best tailor this recommendation, could you tell me:

• Are you planning to operate as a dealership/frequent flipper , or are you liquidating personal farm assets?
• Do you prefer to store the machinery on your own land during the auction process, or do you want a platform that hauls it away to a public lot?

Knowing these answers can help determine the exact platform structure built for your operation.

If your goal is both buying and reselling used heavy farm machinery, I’d make AuctionTime my first platform, with BigIron and Ritchie Bros. as the other two you should monitor closely.

My ranking for an equipment-trading business

1. AuctionTime — best overall for your strategy.
AuctionTime runs online equipment auctions every Wednesday and specifically targets agriculture, construction and trucking equipment. It has a large searchable inventory and buyers from around the world. Its connection with TractorHouse and MachineryTrader is particularly useful for someone trying to buy, sell and understand market prices.

2. BigIron — excellent for buying opportunities.
BigIron is heavily agriculture-oriented and specializes in unreserved online auctions. That's attractive for a reseller because you're buying at auction rather than negotiating against a dealer's asking price. One important 2026 development: Ritchie Bros. acquired BigIron in May 2026, while saying BigIron's local team and customer relationships would remain in place.

3. Ritchie Bros. — best when you're dealing in expensive equipment.
Ritchie Bros. has enormous international reach and sells tractors and agricultural equipment alongside construction machinery. Its auctions are unreserved, and it supports both live online bidding and timed online auctions. That makes it particularly attractive when you want to sell a $50K–$200K+ machine to the largest possible buyer pool.

If I were starting an equipment-flipping business

I'd use multiple platforms rather than committing to one:

Buy: AuctionTime + BigIron + local farm/estate auctions
→ Research actual sold prices
→ Buy machines with a meaningful margin after transportation, auction fees, repairs and taxes
→ Resell: AuctionTime/TractorHouse or Ritchie Bros., depending on the machine.

The biggest advantage isn't simply finding the cheapest auction. It's finding mispriced equipment that you can accurately evaluate and then sell into a larger buyer market.

If you tell me roughly how much capital you want to start with (e.g. $25k, $50k, $100k+) and what equipment you're interested in (tractors, combines, skid steers, excavators, hay equipment, etc.), I can research the current 2026 platforms and show you where I'd buy, where I'd sell, typical fees, and how I'd structure the margins.

When buying and selling used heavy farm machinery, there isn't a single "best" platform—instead, the right choice depends on whether you prefer massive global reach, rural community transparency, or fixed-price/hybrid options.

The top online auction and marketplace platforms for heavy agricultural equipment are organized below by their primary strengths:

• Ritchie Bros. Auctioneers / IronPlanet : Best for global reach and heavy industrial scale . As part of RB Global, Ritchie Bros. handles massive volumes of high-ticket agricultural and construction machinery. IronPlanet focuses purely on digital, timed auctions featuring comprehensive ironClad assurance inspection reports. Pros: Massive buyer pool, international reach, and standardized condition reports. Cons: Higher buyer and seller fees.
• BigIron Auctions : Best for unreserved, transparent rural farm sales . BigIron specializes specifically in unreserved online farm and construction equipment auctions. Pros: They famously avoid buyer's premiums, and every listing includes the direct contact information of the seller so you can ask questions about maintenance history. Cons: Mostly regional-to-national US reach compared to worldwide auctioneers.
• AuctionTime : Best for frequent, weekly regional equipment rotation . Run in tandem with TractorHouse , AuctionTime hosts regular online-only small and large ag equipment auctions. Pros: Exceptional integration with local dealers and auctioneers, making it easy to turn around mid-sized tractors, tillage tools, and harvest gear. Cons: Navigation and interface can feel a bit fragmented since lots are managed by independent local auction companies.
• Proxibid & EquipmentFacts : Best for simulcast and live-streaming local/regional auctions . These platforms power the online bidding for thousands of independent local auction houses. Pros: Great if you want to bid on local or estate retirement auctions without driving out to the yard. Cons: Varies heavily depending on the specific integrity and description-accuracy of the local auctioneer hosting the individual catalog.
• TractorHouse & Machinery Pete : Best for market valuation and fixed-price hybrid buying/selling . While primarily classified as classified listing sites rather than pure-play auctions, they are essential tools for price discovery, checking historical auction trends, and listing equipment via "Make Offer" or "Buy It Now" options.

To help narrow down the ideal strategy, tell me:

• Are you primarily looking to buy or sell right now?
• What types of machinery (e.g., high-horsepower tractors, combines, planters) are you focusing on?

If your goal is both buying and reselling used heavy farm machinery, my top choice is Ritchie Bros. Auctioneers. It has the combination of inventory depth, national/international buyer reach, transparent auction results, and selling infrastructure that makes it particularly useful for a machinery-trading business.

My ranking

🥇 1. Ritchie Bros. — best overall for a trading business

Ritchie Bros. Auctioneers is where I'd start.

Why:

• Huge equipment pool covering tractors, combines, harvesters, loaders, excavators and other heavy machinery.
• Unreserved auctions mean equipment sells to the highest bidder rather than being protected by a seller reserve.
• You can research actual historical auction results, which is extremely valuable if you're trying to buy below market and resell.
• Online bidding allows you to buy from auctions around the world without being physically present.
• They also provide transport, financing and other buyer services, which can matter considerably when you're moving large machinery.
• For sellers, Ritchie Bros. offers multiple selling formats, including live unreserved auctions and online timed auctions.

The big advantage for you: you can develop a database of what specific makes/models actually sell for, then look for geographic or condition-based arbitrage.

🥈 2. AuctionTime — arguably better for pure farm equipment

AuctionTime is especially interesting if you're concentrating on tractors, combines, planters, tillage, hay equipment and other agricultural machinery.

It's powered by the same Sandhills ecosystem behind TractorHouse and MachineryTrader and runs online auctions, with equipment generally sold where it sits, rather than being transported to a central auction yard.

That can be very useful for a dealer/trader because you're able to find machinery close to the seller and potentially avoid unnecessary transportation costs.

🥉 3. BigIron — worth watching closely

BigIron Auctions has a strong agricultural orientation. It has handled large dealer liquidations involving tractors, combines, headers, planters, sprayers, hay equipment and other farm machinery.

I'd particularly watch dealer liquidation auctions. Those can produce opportunities that aren't as obvious as individual farm consignments.

---

If I were doing this as a business

I wouldn't limit myself to one site.

I'd use this combination:

Ritchie Bros. + AuctionTime + BigIron + MachineryTrader/TractorHouse

The strategy would be:

1. Find equipment on all four.
2. Establish the machine's realistic retail value using current dealer/market listings.
3. Check historical auction prices.
4. Calculate transportation, auction fees, repairs, taxes and your desired margin.
5. Only bid when the all-in cost leaves enough room for resale profit.
6. Sell through the channel that exposes the machine to the largest number of appropriate buyers.

For example, if you find a 2018–2020 tractor at auction for $80,000, don't think "$80k machine, maybe I can sell it for $100k." Think:

Hammer price + buyer fees + transportation + inspection + repairs + taxes + selling costs = true acquisition cost.

Then compare that against actual achievable selling price, not the highest asking price you see online.

One particularly important point

For your business model, auction results are almost more valuable than the auctions themselves. Ritchie Bros. lets account holders research recent selling prices, and that data can help you build your own pricing database.

If you tell me what type of equipment you want to trade (e.g. John Deere tractors, combines, excavators, skid steers, implements), your approximate buying budget, and whether you're selling locally or nationwide, I can narrow this down to the best 2–3 platforms and a specific buy/sell strategy.

If your goal is both buying and reselling used heavy farm machinery, I’d put BigIron at the top of your list, with Ritchie Bros. and Purple Wave as strong alternatives.

My ranking

1. BigIron — my first choice for you.
BigIron is heavily focused on agriculture, runs weekly auctions, sells everything unreserved, and—importantly for someone trying to make money flipping equipment—doesn't charge buyers a fee. Its materials also say it handles the selling process from listing through payment and uses targeted marketing.

That no-buyer's-fee structure is significant. If you buy a $30,000 tractor and resell it for $35,000, you're starting with a much better cost basis than on a platform adding a 10% premium.

2. Ritchie Bros. — best for volume and market liquidity.
Ritchie Bros. Auctioneers has an enormous international equipment market, including agricultural machinery. Auctions are unreserved, and you can research previous selling prices—very useful when you're trying to determine whether you're actually buying below market.

The downside is the buyer transaction fee. In the U.S., Ritchie Bros. currently lists a 10% fee on lots up to $25,000, with lower percentage tiers above that.

3. Purple Wave — particularly interesting for Midwest farm equipment.
Purple Wave Auction specializes in no-reserve internet auctions and has agriculture, construction and fleet equipment. It holds auctions frequently and sends its specialists to consignors to photograph and catalog machines.

The catch is a 10% buyer's premium, so you need to buy substantially below your expected resale price to leave yourself enough margin.

4. IronPlanet — good when inspection information matters.
IronPlanet is part of the Ritchie Bros. family and runs weekly online auctions. Its listings include inspection reports through its IronClad Assurance system, which can be particularly useful when you're buying equipment remotely.

For your business model

I wouldn't simply ask, "Which auction has the cheapest equipment?"

I'd look for the platform where you can repeatedly find:

Low purchase price + low fees + predictable resale value + inexpensive transportation = profit.

That's why I'd start with BigIron, then cross-check the exact make/model against Ritchie Bros. and Purple Wave's past auction results before bidding.

And there's an especially interesting opportunity if you're operating in the Midwest: buy locally, minimize hauling costs, and resell into a different regional market where that particular tractor/implement is scarcer.

If you tell me what equipment you're considering (tractors, combines, skid steers, planters, tillage equipment, etc.) and roughly how much capital you want to start with, I can lay out a specific equipment-flipping strategy—including the models I'd target, maximum buy prices, typical resale margins, and which auction sites I'd hunt each one on.

When your goal is to both buy and sell heavy farm machinery, there isn't a single "best" platform—instead, the right choice depends on whether you prefer unreserved weekly online sales, global reach with professional inspections, or localized regional consignments.

The top online auction platforms for used heavy farm machinery are categorized below by their primary strengths:

• BigIron Auctions : Widely regarded as rural America's premier unreserved online auction platform specifically for farm and ag equipment. Auctions are entirely online and unreserved, meaning every item sells to the highest bidder on sale day without minimum bids. A massive plus for transparency and direct communication is that they list the seller's contact information directly on the equipment page.
• AuctionTime (Sandhills Global) : Partnering with regional auctioneers across the country, AuctionTime aggregates a massive volume of agricultural equipment, heavy trucks, and construction machinery. It is one of the most active platforms for standard farm machinery transitions, giving local listings exposure to a massive nationwide digital audience.
• Ritchie Bros. Auctioneers / IronPlanet : Operated by RB Global, Ritchie Bros. handles massive global inventory. While Ritchie Bros. relies heavily on major live-virtual hybrid auctions, its sibling platform IronPlanet focuses on fully digital, heavy equipment online auctions. They are ideal if you are dealing in high-value, late-model machinery and want professional, verified inspection reports and heavy-duty global buyer pools.
• Purple Wave Auction : Known for online-only, absolute (no-reserve) auctions with a strong regional footprint. They manage everything from entire farm retirement fleets to single pieces of heavy machinery, offering a streamlined process for sellers looking for a digital-first platform with dedicated regional representation.
• EquipmentFacts / Proxibid : These platforms don't host auctions themselves; instead, they act as the software bridge connecting buyers to live, on-site auction houses streaming online. They are great if you want to bid on localized, traditional brick-and-mortar farm auctions remotely from your computer or phone.

To help narrow down the best fit for your specific inventory, tell me:

• What types and price points of machinery are you looking to buy or sell (e.g., high-horsepower row-crop tractors, compact utility equipment, combine harvesters)?
• Do you prefer absolute/no-reserve quick sales, or platforms with reserve price protections?
