Frequently Asked Questions

What dipper stick fits a Komatsu PC170-10 or PC170-11 excavator?

Broken Tractor carries two dipper sticks for the Komatsu PC170-10 and PC170-11: a 9 foot 6 inch stick, part number 21K-70-00720, and an 8 foot 7 inch stick, part number 21K-70-00610. Both are new take-off units. Choose the length that matches the stick currently on your machine or the reach configuration you want.

What dipper arm fits a Komatsu PC220-8 or PC240 excavator?

We offer a 10 foot dipper arm, part number 206-70-00402, that fits the Komatsu PC220-8, PC240-10 and PC240-11. It is a new take-off assembly pulled from a new machine, not a rebuilt or used field unit.

What does new take-off mean for a Komatsu excavator dipper arm?

A new take-off dipper arm has been removed from a new Komatsu machine, so it has not been rebuilt or used in the field. These sticks offer OEM-quality fitment at a lower cost than buying new from the dealer.

How do I make sure a dipper stick fits my Komatsu excavator?

Match the Komatsu part number on your current stick, such as 21K-70-00720, 21K-70-00610 or 206-70-00402, and confirm your exact model and serial number. Fitment can depend on the serial range of your machine, so check it before ordering. If you are unsure which stick you need, call (800) 909-7060 and our parts team can confirm the right one.
