I have a Rankin mechanical thumb mounted on my GC2310. I have used it almost every time I've used the backhoe, and wouldn't think of having a backhoe without one now.
The Rankin is manufactured in Yakima, WA - here's a web link: Rankin Equipment Co.
I'm also curious about this so if you don't mind, keep us posted in here. I'm also curious if an hydrolic thumb would be an option for this little machine...
(BTW, on the Rankin Web Site, look for Thumbs on the left menu)
Since I'm trying to keep costs down I will not be purchasing a hyd thumb. I'm sure I'll be sorry since I'm tearing down a house, wrecking a large concete patio, concrete basement walls and then building a new house. Penny wise and pound foolish? ;-(
Wow, jetwoz- for all that work, I'd agree with two_bit-- I also think you should invest in a hydraulic thumb! I doubt you'd regret it.
jaybrad-- those pics were at the door end- of course they look good, I gotta be able to get the cars in! Other end of the garage is a whole different story.... You'll notice that grandson helps kepp the "clutter factor" right up there. There- feel better?
