Frequently Asked Questions

What is the difference between a mechanical and hydraulic thumb for a Case excavator?

A mechanical thumb uses a manual pin adjustment that you set by hand, while a hydraulic thumb is cylinder operated so you can adjust it from the cab. Broken Tractor carries both types across the 70, 120, and 160 series, plus a hydraulic thumb kit for 200 series machines. Choose based on how often you need to reposition the thumb during work.

How do I choose the right thumb kit for my Case excavator?

Thumb kits are matched by machine operating weight and bucket width. Broken Tractor offers thumbs for 70 series (15,000 to 22,000 lb, 12" to 40" buckets), 120 series (24,000 to 36,000 lb), 160 series (30,000 to 46,000 lb, 24" to 58" buckets), and 200 series (40,000 to 53,000 lb). Match your excavator weight class and bucket width, or confirm fitment with our parts team before ordering.
