    Who builds the best hydraulic thumb for a mini excavator. I have a customer wanting one to fit a 50D and wondering what better options are available than the Deere thumb. I was looking at CP, but it looks like a Deere thumb. They may build them for Deere.

    JD, what kind of thumb does he want? Two or three pronged or a solid thumb with a thumb nail? Does he want standard linkage or a progressive link set up? I have looked at thumbs and manufacturers for the last 1 1/2 years and I think the way I am going to go when I replace mine is Peck Weld in Washington State. I think I found out about them from MiniMax.......and I think he has one of their set ups.

    He just asked for a thumb. Deere's is a 2 prong, but is not very heavy built. I would like to explore options and make a recommendation to what I feel will best fit his needs. We kicked the snot out of a Kubota U45 hands down, with the exception of the back fill blade and price we were superior in all other categories with a 36" bucket. We had to put side by side and show them the price difference. Like I always say, demo, demo, demo. 50D really performed better than I even thought it would. Spec sheets were close demo was not. I do not want to go cheesy on the thumb.

    i would suggest werk brau[not sure of spelling]if they want a true thumb not a cover plate,Ive found these to be the best especially for rock work.

    I have a werk-brau thumb on my machine and have liked it alot. It folds flat against the stick. It is about time to replace it. KSSS, I believe has the same set up. Mine is an older version with only 90 degree rotation. New standard thumbs are 123 degree. I like werk-brau's E-Z Grip thumb design for what I do. Werk-brau progressive link will give you 131 degree rotation. PSM series 2 Magnum progressive link will give you 162 degree rotation. CWS progressive link claims 180 degree rotation. HPF pro-link will give you 172 Degree rotation. Amulet makes a nice set up also. There is still Dymax and Central Fabricators to look at. I have looked at all of these and more, talked to their sales reps/engineers, have spec sheets and drawings in front of me as I speak and will still choose Peck Weld in Tacoma Washington. I have talked with Steve Peck (owner), his left hand man, Don, their engineer and these guys can give you what you need/want and then some for a better $$ than what I have seen from the others.

    As far as stock Deere thumbs go........they are notorious for being crap and bending. Almost everyone I have spoke to prefers to not get a Deere thumb and get something else.......anything else.....but their stock product. I set rock and for me werk brau's e-z grip thumb with thumb nail design
    allows me more versitility in what I do, so I will stick with that design instead of the "prongers" that are coming out on thumbs.

    I like the Werk Brau easy grip thumb. The one I just put on my TK has 128 degrees of rotation in a direct link thumb. The best thing is it folds flat and does not extend beyond the width of the stick and it costs less than half what a progressive link does. I wanted a Prog link but I could not justify the money. JD if your looking at the WB line perhaps you may also want to look at their mech. coupler. It is an excellent coupler. The JD coupler is anything but quick. I wont argue that it is secure but who has time to unscrew the wedge coupler?

    He will mostly be working with brush and general lifting. No rocks.

    CWS hands down, we've got a bunch of excavators here with anything CWS on it and their thumbs are top notch.
