QR Code Link to This Post
The “HYMUS ERIE” marking you see on the blade arm is almost certainly a misspelling, misreading, or weathered version of “BUCYRUS ERIE” — a very common brand from the mid-20th century. Bucyrus-Erie (later Bucyrus International) was a major American manufacturer of heavy equipment, especially cable-operated blades, winches, and attachments for crawler tractors. They made dozer blades, angled blades, bull graders, and cable control units that were factory-fitted or aftermarket-added to many brands of tractors, especially International Harvester (IH) models.
Key features from the photo
• Red paint — Strongly points to an International Harvester (IH) crawler tractor. IH was famous for their “red” construction and industrial machines (Farmall farm tractors were red too, but crawlers like the TD series were bright red in that era).
• Crawler tracks — Full tracks instead of wheels, typical for dozers/bulldozers used in earthmoving, logging, land clearing, or construction.
• Cable-operated blade — The big arched arms, hydraulic or cable cylinders, and rigging are classic Bucyrus-Erie style from the 1940s–1950s. These were often cable-controlled (via rear winch) rather than fully hydraulic.
• Exhaust stack — Tall, straight stack with a rain cap, common on older diesel/gas crawlers.
• Front blade with “4” marking — Likely a fleet number or ID painted on by a previous owner (logging company, construction outfit, etc.).
• Overall condition — Abandoned/yard art/sitting for years in a wooded area (moss, rust, overgrown), which is very common for these 60–80-year-old machines.
Most likely model
This is probably an International Harvester TD-6, TD-9, TD-14, or TD-18 series crawler (from roughly 1940s–1950s), equipped with a Bucyrus-Erie dozer blade attachment.
• These were workhorse machines for logging, road building, land clearing, and general dirt work, especially in rural/forested areas like parts of California.
