International Harvester 915 Combine Harvester
The International Harvester 915 was IH's largest conventional combine of the late 1960s and 1970s and was a serious high-capacity machine in its day. It is remembered for its five-walker layout, hydrostatic drive, DT-414 diesel power, and strong presence in maize and grain country.

What the 915 is used for
The 915 was designed for large farms of its era harvesting maize, soybeans, wheat, and other cereals. It gave operators more capacity than smaller IH conventional combines and was available with crop-specific heads for broad Midwestern use.
Today, it is primarily a collector, hobby-farm, or limited-acreage machine. A well-kept 915 can still harvest economically where downtime is acceptable and the owner is comfortable maintaining vintage equipment.
Why the International Harvester 915 stands out
The 915 is notable as a flagship conventional IH combine and as one of the last large IH walker machines before the Axial-Flow era. Its straightforward mechanical construction and historical importance make it appealing, although parts sourcing requires more planning than with later combines.
Buying a used International Harvester 915
Check the DT-414 for cooling, fuel-system, and turbo condition, then inspect the cylinder, concaves, walkers, walker cranks and bearings, shoe, augers, elevator chains, and hydrostatic drive. Look for structural corrosion, worn header-drive parts, and evidence of long outdoor storage; verify parts availability for the exact serial number before committing.
