Nice job Joe. Looks like you got the 36" too. My main use of the thumb will be with my forks. Just thought why not buy a second base for the bucket. That gives me a dual purpose thumb.

Thanks! Yup, 36" of grabbing goodness. I like your thumb/forks mash-up. I can see where that can be a very handy combination. And the extra mounting base gives you tons more usefulness with the second bucket for a fraction of the cost of another thumb. You know you'd be kicking yourself if you didn't do it.

Joe

Did you add a smaller piece of angle on the very front edge of your bucket, where your chain hook is welded? It looks like in your pictures that it has more metal on the front edge compared to my R4041 bucket. I know that I will have to add the 3" angle to mount, like what you had done.

Yes I did add a piece of 2" angle to the top of my bucket and welded my hooks to that. The top of the bucket is boxed but I didn't know how thick it was.

Ok, thank you. I was looking into beefing up my bucket before adding a thumb also.

George2615, I followed what you did with mounting and all; but I have a couple of questions per your thumb. I got mine and while to the naked eye it appears flat and straight, once placed on the level metal of bucket the brace bracket (both that I received) seems slightly warped. Was yours just slightly off also? I believe that when I bolt it down - if I start in the middle and work towards the outside - it "might" squeeze down flat?

Also, the pins (with holes for slip in lock pin) provided for the out most holes of the brace need to be "forced" in and out? They are "way" to tight to be just simply pull three pins and switch from forks to bucket!! Did you do any modifications to the hole to enlarge them slightly? Or is it just my luck to get the one that is poorly made? I am looking for some 3"x1" top link pins to replace those provided but am not having any luck finding any. My local TSC has a slot on their wall for some 1"x3 & 13/16" pins but of course they are out and don't know when they may be restocked! n They have 6" lengths and I may need to buy those and just cut them down to fit. But that's at the end of my mounting process to worry about.

I also saw the extra holes for the hydraulic ram that you added to yours. Any problems with the lower set as for contacting the thumb cross-bar? Do you ever even use the others? Your pictures don't show it mounted in other than the original holes, so I wonder if it is worth it to have him drill some in mine or not? I would "probably" only use it for when the thumb is on the bucket as it seems that my bucket is "way" smaller than yours. Mine is approx 55" wide but narrow to the top and that 36" thumb has a "very" long reach!

For now I'm just trying to find out about the quality levels that others have received with their Greens Thumb. I'm currently questioning mine as is my welder/fabricator whom has pointed out these deficiencies to me -- repeatedly! Any further guidance you could offer as per your mounting experience would be greatly appreciated. Thanks, Greg

A local steel shop in San Diego will have 1.00" round steel rod for reasonable prices. If you need 25mm, it is harder to find locally. Don't go smaller than that, or you risk bent pivot pins.

Questions answered by paragraph. Perhaps since I posted this 5 years ago quality control may have suffered in production of the mount.
1) Both my mounting plates where flat, not warped. Depending on how warped yours are the bolts might squeeze it down. It's a pretty thick mount plate though.
2) My three pins slide in / out easily. Remove your pins and take a file or die grinder to ream the holes slightly or you can replace them with cut down pull pins from TSC or pull your pins and clamp in a vise and sand them down with some emory or sandcloth so they fit easier.
3) No, I don't use the other holes. I drilled the extra holes to be able to change the full open / full close position of the thumb. You may not need to drill additional holes.
4) Just an FYI, so far I have found my thumb most useful with my forks and have used it very little on the bucket.

Thanks for the reply George,
#1 - Neither of my base plates are warped "all that bad" and I do think I can squish it flat working from the middle out, and using an impact to bolt it down. I was just curious, since they both are identical including the minor warp.
#2 - Yes, I am going to have to grind down the insides some because it takes a punch and hammer to remove the pins now. But, I will also try your other ideas like using emory on the pins some too.
#3 - That's what I wanted to hear about your added holes and I don't think I'll need them; but while the thumb is at the fabricators I'll probably have them added anyway, just for an in case situation.
And for #4, that was my original main intention for the thumb. To use with my forks for my annual limb cleaning around my small property. Making 1 or 2 trips hauling brush vice my current many, many trips. I just thought why not get another base plate and be able to use it on either. But, after seeing just how heavy it actually is - I'll probably end up leaving it on the forks for the most part.
George, have you experienced any problems with the thumb pins getting rusted at all? That's another item my fabricator brought to my attention -- there are "no" grease fittings at the pin holes [like on every other backhoe or grapple I've looked at] and they are a swivel item? I'm debating whether it would be wise to drill, tap, and install grease fitting also?

dfkrug, Thank you for the useful suggestion and that will be a viable resort if needed. But, since I'd have to cut and grind anyway with steel rod I might as well just get the longer pins from TSC (local shop, about 2 miles away) and cut them short enough to fit and drill a keeper hole in.

Greg,
I just went outside and looked at my pins. (Brrrrrrrr 21 degrees out there) 5 years old and only have a couple spots of minor surface rust. They still spin freely without grease fittings. Plus they are stored outside all year. I think if you ream / file the holes slightly and grease the pins before installing them you'll be fine.

Okay, thanks for that additional info -- even tho it sounds "very cold" to me!! I appreciate you confirming about the rust and need for grease fittings. Get u back inside with a cup of hot cocoa or cider! Thanks.
