    I was wondering if anyone here has chnaged their factory KX series thumb for something different. The factory thumb on my KX121-3 is too small for my liking. Anyone who has one, do you feel the same? I feel it pivots long things while pinching and could be wider. I had a custom hyd. thumb put on L48s and it is great, almost wide enough to close a 24" bucket and the plate is solid as opposed to tines with most thumbs. This is what I want, any suggestions?:usflag:

    Will post pics tommorrow.

    Curtisfarmer, I saw a guy here who had a 161 and he had a pro. link thumb by HPF on his machine (like minimax's thumb). I personally would get rid of the kubota thumb and get one from HPF or PSM here in WA; whenever I end up picking a mini up. I like pro link thumbs and wider thumbs which both companies offer. They are a tad spendy but IMO worth it. I'm sure mimimax on here could vouch for that.

    The HPF pro-link mini thumbs are awesome. I was quoted $3,400 I believe about 14 months ago for my dad's 303CR, which included a new, longer cylinder and all the installation.

    Check out www.northsaw.com

    He built ours for our Kobelco 70SR, it's a great thumb, and a great price. He is a super nice guy to work with too.

    If you go to his website look under more pics, under the first link (029A) he has pics of a thumb he built for a KX121.

    I want something like Nedlys style....large and wide, I may go without the serated edges as I do alot of rock work which may cause scratches. I just realized I have the QA to deal with as I was sitting in bed last night. I don't want to spend big dough ($500+). I was wondering if some fabrication could be done to widen it....and if it would hold up. If not, get a new thumb plate without the piston and such, don't want to send big dough again. I guess I am wondering about radius, clearance, and other measurments I should be aware of ....or woul someone who does this for a living obviously know everything I am worrying about. It would be nice if I could get an off the shelf replacement, unbolt piston and replace? It is snowing again, back to back plow days but I will post pics today.

    Nedly, that is a great link, EXACTLY what I was thinking. I am going to call him and see if he has an off-the -shelf solution. Thanks

    I will try and find it but on a site somewhere maybe HEF there was a kubota where they took the stock thumb and just added a prong on each side to widen it so on a 36" bucket 4 prongs that when closed they were all in between the teeth.

    I seen on Ironplanet I believe someone had a 161 that they modified the factory thumb like NEUSWEDE said and had 4 finger thumb and it looked good. Your already wide enough back by the pin just have two more finger welded on with bracing in between, I would think be alot cheaper.

    Thats a good idea. You can make a template of your tines and go to a steel shop and have some pieces burnt out, then get the appropriate size steel to widen it and weld the tines on the out side. That would be more in the area of $500. Check out my pic thread. I had some new tines burnt out and replaced the tines on our Deere 27.
