Frequently Asked Questions
What log arch fits a Cat D5K with a Carco PA40 winch?
Broken Tractor carries a log arch built for Cat D3K, D4K and D5K dozers equipped with a Carco PA40 winch (SKU PV4409). PA40 winch fitment is confirmed for all three of these models. If your D3K, D4K or D5K has a different winch, confirm fitment with our parts team before ordering.
Which winch log arch kit fits a Cat D6K or D6K2 dozer?
The Winch Log Arch Kit for Caterpillar Dozers (SKU PV4412) fits the Cat D6K, D6K2 and the Next Gen D4. It comes as a complete assembly, so you are not piecing parts together for the install.
Will the roller log arch head fit my Cat dozer?
The Dozer Log Arch Head with Rollers (SKU PV497A) fits dozers under 15,000 lbs. It is a roller-equipped arch head made in the USA. Check your machine's operating weight against that limit before ordering.
What is a winch log arch used for on a Cat dozer?
A winch log arch is used for winch-assisted log skidding and arch extraction on Cat crawler dozers. It is common on forestry and land clearing jobs, where it helps the winch line pull and control logs behind the machine.
How do I choose the right log arch for my Cat dozer?
Pick the log arch by your exact dozer model and, for the D3K, D4K and D5K, by winch: PV4409 is for machines with a Carco PA40 winch. PV4412 covers the D6K, D6K2 and Next Gen D4, and PV497A fits dozers under 15,000 lbs. If you are unsure, call (800) 909-7060 with your model and winch details so our parts team can confirm fitment.
