Don't know much about them other than the company is located not far from me. The phone number from the book is 574-255-4746 /forums/images/graemlins/smile.gif
There was one at auction last summer, so I called the company to find out info on that model - seemed like very nice, live, helpful people. Ended up too big & too much $$$ for me...
Kelley and Koyker are the same company. The backhoes are sold under both names. I believe Kelley mfg. makes them for both companies. I had a Koyker KB65 on a Massey Ferguson 1020 and I liked it very much. When I bought my Kioti LK3054 I traded up to a KB75 which I use commercially and it too preforms quite well. You can do a web search for Koyker and find their web site.
