Didn't know if anyone on here would have any experience with the old Timberpro 620E (aka Timbco on wheels) or the newer 630/B/C/D series of 6 wheeled feller bunchers or processor machines. I guess the 8 wheeled machines, 830/840, would probably share a lot of components or similarity as well... maybe...not sure I've ran a handful of regular track bunchers, including Timberpro and Timbco. I see advantages (and disadvantages of course) to the wheels, but just poking around to see if there's any first hand experience to share. I've got a guy who might want to sell his, tilting cab version, and it has my interest.

The tire situation is complicated. https://www.customtruck.com/blog/what-you-need-to-know-about-the-current-tire-shortage/ Tigercat has made a fixed processor head (depending on tree size) that could be mounted to an old hot saw levelling 822 or 830, 855 etc. 18K hour old Tigercat 830 with SP head in Scotland Timberpro 830B (8x8) and Logmax 9000 which needs a new saw chain (Germany) Old 830 with waratah 624 super
