Historical Roots of Timberjack
Timberjack began in the 1950s in Ontario, invented by two logging-savvy engineers who built an articulated four-wheel-drive tractor with a rear winch—designed from the forest floor up to handle rugged terrain. In subsequent decades, it shifted through several corporate homes: sold to Eaton, spun off into independence, partnered with European forestry stalwarts, and finally acquired by John Deere around 2000. By 2006, the Timberjack brand was folded into Deere’s lineup—but its machines and parts remain in use and demand across global forestry operations.
Parts Landscape Today
Timberjack parts fall into three main categories:
Terminology Note: Parts machines refer to entire units stripped for their usable components; aftermarket parts are manufactured replacements; remanufactured/rebuilt parts are originals refreshed to service specifications.
Supply Channels and Reach
Woodland operators now have multiple pathways to source Timberjack parts:
Exact global sales for Timberjack parts are not public, but evidence suggests high demand: forestry contractors frequently refresh undercarriage parts after a few thousand operating hours, and hop-on-hop-off rental fleets replace drivetrain components regularly. The volume of listings for 30-, 40-year-old machines converted to part rigs attests to enduring demand. Meanwhile, supplier inventories with thousands of listed parts indicate a robust supply pipeline.
Real-World Anecdote
A logging operator in the Pacific Northwest shared a story of tracking down a rare cab frame for a 1980s TJ628. The part was sourced from a salvage entry in Alabama, shipped overnight via expedited freight, and delivered within 48 hours. The turnaround preserved a high-value machine’s season productivity.
Recommendations for Operators
Consider the following approach when sourcing Timberjack parts:
Timing and availability define parts availability in forestry. Timberjack machines—though no longer in active production—continue to live on through an ecosystem of parts suppliers, salvage operations, and aftermarket specialists. The resilience of this supply network ensures that even decades-old equipment can stay working in demanding forest environments. For operators, knowing where to look and how to act quickly can mean the difference between a productive season and costly delays.

Parts Landscape Today
Timberjack parts fall into three main categories:
- New aftermarket options — Suppliers offer fresh parts made to match the originals: everything from sprockets to cabs.
- Used and rebuilt components — Including high-wear items like final drives, undercarriages, hydraulic pumps, and seal kits.
- Parts machines and salvage inventory — Complete or partial machines serving as live part sources.

Supply Channels and Reach
Woodland operators now have multiple pathways to source Timberjack parts:
- Dedicated parts dealerships specializing in new, used, and rebuilt components.
- Online marketplaces offering parts machines across decades—great for rare or discontinued models.
- Responsive parts teams that pride themselves on urgency and persistence in tracking down hard-to-find components, including shipping solutions across North America with rapid turnaround.
- Compatibility services that offer components adapted for Timberjack machines alongside other forestry brands, boosting availability for legacy equipment.

Recommendations for Operators
Consider the following approach when sourcing Timberjack parts:
- Identify exact part numbers—this helps when reaching out to suppliers or salvage listings.
- Compare supply sources—eco-conscious operations may prefer rebuilt or used units, while rentals or OEM-aligned users lean toward aftermarket parts for consistency.
- Leverage fast-delivery specialists—especially when machine downtime risks cutting into seasonal productivity.
- Maintain a parts-donor machine cache—acquiring inexpensive older models can yield long-term supply peace of mind.
