What is my International Harvester tractor worth?
IH and Farmall tractors still pull wagons, run augers and bale hay across the Midwest. Condition and originality set the price.

What International Harvester tractors bring used
Typical asking ranges for sound machines. Hours, a loader, a cab and where you are standing move every one of these.
How International Harvester holds value
The letter-series Farmalls (H, M, Super M) are collector tractors first and working tractors second. Original paint and straight tin move the number more than anything mechanical.
The 66 and 86 series — 806, 1066, 1466 — are the ones still doing real work. A 1066 with good tin, tight hydraulics and duals is one of the most sought-after used tractors in the country.
Parts availability is excellent and the market knows it, which keeps a floor under even rough examples.
What this estimate cannot see
- Dealer distance. Buyers pay more when parts and service are close by.
- Service records. A folder of receipts is worth real money to a cautious buyer.
- Photos. Clean pictures from all four sides regularly add more than any option on the machine.
- Timing. Tractors sell best ahead of hay season and planting. The same machine brings less in the wrong month.
Common questions
- Put the horsepower, model year, hours and condition into the calculator on this page and it returns two ranges: what to ask selling it privately, and what it would likely bring at auction. Then type your exact model into the comparables box to check it against what machines like yours ask on the wider market.
- The letter-series Farmalls (H, M, Super M) are collector tractors first and working tractors second. Original paint and straight tin move the number more than anything mechanical.
- Hours only matter against age. A tractor puts on roughly 200 hours a year, so a 10-year-old machine with 2,000 hours is average. Half that adds value; double it takes value off — usually 15 to 25 percent at the extremes.
- A standard equipment listing is free. Equipment auctions carry a 4% seller fee ($75 minimum) and a 5% buyer premium ($75 minimum), both capped at $2,500, and no subscription is required to start one.
