The best heavy equipment auction sites for buyers
Ritchie Bros and IronPlanet cover the widest range with the clearest published terms, Purple Wave is strongest for Midwest farm and construction gear at a flat 10 percent premium, and GovDeals and Copart/IAA suit specific niches. Compare buyer fee tiers, inspection reports and loading windows before price, since the invoice rarely matches the hammer number.
Ritchie Bros: the biggest unreserved sales
Ritchie Bros runs live, online and hybrid unreserved auctions of construction equipment, trucks, trailers and farm machinery in more than 190 countries, and it is now part of RB Global alongside IAA and IronPlanet. Registration to bid is free whether you show up in person, bid online, or use PriorityBid. A refundable deposit of roughly 25 percent of the bidding limit you request is typical, though account verification or approved financing can cut or waive it, and Ritchie Bros. Financial Services offers up to 100 percent financing with no money down for qualified buyers.
Payment is due within 7 days of the auction closing. Wire transfers need to clear at least two banking days ahead of the sale, and credit cards can be held for up to 5 days domestically or 45 days internationally; miss the deadline and a 2.95 percent iClosing convenience fee applies. Ritchie Bros does not publish a flat buyer's buyer's premium percentage where we could confirm one this session (checked September 2026), so ask your account manager for the current figure before you set a maximum bid. Selected lots carry an IronClad Assurance condition certification, which is closer to a standardized inspection report than a self-reported listing.
IronPlanet: the clearest published fee schedule
IronPlanet, also an RB Global brand, sells used construction, agricultural, trucking, forklift, crane and mining equipment plus government surplus, through online auctions, buy-now listings, offers and sealed sales. Signing up is free, and IronPlanet is the one platform in this group with an exact, fully published fee table we could verify directly on its own site. Miss the 5 business day payment window after a contract closes and a default fee applies, tiered from $500 on a $2,500 sale up to $6,500 on anything over $100,000, plus a late fee running from $10 to $250 per business day depending on the price tier.
Beyond that, a credit card payment adds a 2.95 percent convenience fee through iClosing, storage runs $25 a day starting on day 9 after the sale, and leaving a machine on the yard past 15 calendar days triggers a relocation fee of the greater of 1 percent of the sale price or $250. IronPlanet's own description of its condition reports is blunt: what you see in the report is meant to be what you get, backed by the same IronClad Assurance certification used across RB Global's brands.
Purple Wave: flat premium, no inspections
Purple Wave specializes in no-reserve farm, construction and transportation equipment auctions concentrated in the Midwest, and its terms are the plainest in this comparison: a flat 10 percent buyer's premium is added to every winning bid, full stop, per its published auction terms. Payment is due by 4 p.m. on the second business day after the auction, by wire, certified check or credit card, and credit card payments are capped at $3,000.
Purple Wave does not perform mechanical inspections. Listings show only what a photo and a spec sheet can confirm, mileage, weight and accessories, and the terms say plainly that cosmetic or body damage may exist even where the listing does not mention it, so the inspection period before bidding is on you. Payment and abandonment disputes are heard under Kansas law in Riley County District Court, which is worth knowing before you skip reading the fine print.
BigIron: broad categories, thin public fee data
BigIron markets itself as a marketplace for equipment, land and even livestock, spanning farm, construction, transportation and industrial machinery alongside real estate and an IronExchange make-an-offer option. Signing up to bid is a simple online form. Where BigIron falls short of the others here is public documentation: its how-to-buy and terms pages did not load for us this session, so we cannot confirm a buyer's premium, a fee schedule or a payment deadline (checked September 2026). Call its customer service line at 800-937-3558 and get the current terms in writing before you commit to a bid.
GovDeals: agency surplus at public-sector prices
GovDeals lists surplus, seized and outdated items from cities, counties, school districts, transit authorities and utilities, and its equipment categories include excavators, loaders and cranes alongside trucks and buses. It really is open to anyone who registers, no dealer license required. We could not confirm a specific commission or payment-processing fee on a govdeals.com page this session, so treat any percentage you see quoted elsewhere as unconfirmed until the checkout screen shows it to you directly.
Copart and IAA: for damaged and lender units
Copart and IAA are primarily vehicle marketplaces, but both move insurance-total-loss heavy trucks and other lender-released commercial units alongside cars and pickups, and IAA also runs a government fleet channel. IAA charges a flat Service Fee of $105 per unit plus a $15 Environmental Fee on top of its tiered buyer fee schedule; Copart's published fee schedule is similarly tiered by sale price and payment method, so treat any single dollar figure you see quoted for either one as a snapshot rather than a permanent rate (checked September 2026). Neither is built around excavators or loaders the way Ritchie Bros or IronPlanet are, so use them here mainly for damaged commercial trucks.
Lender-appointed repo brokers
A smaller class of regional brokers sells repossessed and off-lease equipment on behalf of banks and equipment finance companies, usually through a sealed rather than a live format, so you submit one number instead of watching a live bid ladder climb. Terms vary broker to broker far more than at the national platforms above, so read the sale document for that specific listing rather than assuming any standard fee structure applies; our sealed-bid vs live bidding comparison covers how that format changes your strategy.

Hours, PIN and undercarriage
Before the fee schedule, check the machine itself. The hour meter reading tells you roughly how much life is left on major components, but a meter can be swapped or simply stop working, so cross-check it against service stickers and hydraulic wear rather than trusting the digits alone. The product identification number (PIN) is the equipment equivalent of a VIN; run it against the seller's paperwork and any lien records before you commit money, the same way you would run a VIN on a car. On tracked machines, walk the undercarriage yourself or pay for a report that does, since track and sprocket wear is one of the most expensive surprises a listing photo will not show you. The Association of Equipment Manufacturers publishes general safety and operating standards worth knowing before your first bid, at aem.org, and OSHA's own equipment standards, at osha.gov, cover what you are legally required to do with the machine once it is on your jobsite. Manufacturer sites such as Caterpillar's also carry serial-number-based parts and service history lookups that are worth running against the PIN before you bid.
Where equipment owners compare notes
Auction listings tell you what a seller wants you to see. Working owners tend to be blunter about which platforms actually deliver a machine on time and which fee lines surprised them after the invoice arrived, and the Excavator Owners Forum is a reasonable place to search a specific model or platform name before you bid, alongside whatever service history you can pull yourself.
Common questions
Do I need a dealer license to buy heavy equipment at auction?
No. Ritchie Bros, IronPlanet, Purple Wave, BigIron, GovDeals and Copart/IAA all register private buyers directly. A license mostly matters for wholesale vehicle marketplaces, not equipment auctions.
Which platform is cheapest for a single machine?
There is no single answer, since only Purple Wave and IronPlanet publish a full buyer fee schedule we could confirm. Compare the total invoice, not the headline hammer price, before you bid anywhere.
Can I get equipment financed at these auctions?
Ritchie Bros offers up to 100 percent financing through Ritchie Bros. Financial Services, which can also reduce or waive the usual deposit. The other platforms in this comparison do not advertise in-house financing on their public pages.
