ECOTRIC Backhoe Thumb Excavator Attachment Boom Width Compatible with Woods

So I love the thumb, but unless you want to modify it, pay attention to the 3.5" width for your boom. Mine was a half inch over and it would not fit. I did not want to return it because it seemed like it would do the job. So let the modifications begin.....lol. 1. Bolt On (First 3 pics): So I cut it in half and bolted it on with longer bolts and one longer pin. The longer bolts and one longer pin would not allow me to put the thumb in the storage position but i was able to test it out. Whoooo yeah loving it!!! But not being able to put in in the storage position was bugging me and would be in the way when digging. 2. Weld On: So had a welder come out and weld it in place. It was already bolted where I needed it and I knew it worked, so he welded it right where it was. Then I took the bolts out. You can see where he welded it across the top and sides of each side bracket. I may cut the excess metal off later, but for now they serve as a good protector for the hydraulic hose connection (already took a hydraulic fluid bath since owning the excavator...lol). Any way, no I can use all the positions of the thumb and it works great. Already moved several large branches and rocks. Great quality product....just pay attention to the size details and measure twice unless you are willing to modify it like I did. Hope my modification will last forever, but if not.....it was worth it in my opinion. Modify at your own risk but you will love it. Note: I have a Bobcat Mini-Excavator 418.

Works great with my New Holland Tractor. You don't realize how important a thumb is until you don't have one. I have a small tractor so the thumb didn't exactly fit tight, but shimmed it with some metal and welded the metal to the thumb not the tractor, so it wouldn't weaken the backhoe arm (or cancel any warranty). I've picked up things so heavy with it the front came off the ground. I am not disappointed at all. Helped tear down a house, pull stumps from the ground you name it.

I have not yet installed it , however it comes with everything needed to in stall and is very rugged. It should work well for what it was designed to do .

I mounted the thumb on my Harbor Freight trencher/back hoe and it fit fine. While the instructions are a waste of paper, mounting it was easy. The instructions consist of an exploded view and parts list and even that was messed up. It arrived 2 days early and was in good condition. Well constructed. It will pick up everything, as advertised. I’m very happy with the purchase.

For you HarborFreight Trencher/Backhoe owners This fits perfect, most likely made for it! I have parts of a EBay 18” weld on thumb. ( couldn’t get the hole thumb delivered, packaging Sucks) This thumb is completely on a different level many more thumb settings and it’s out of the way self containment. The part that bolts on is thicker than the weld on piece. Weld on thumb has to be removed or strapped on somehow if you want to dig, no out of the way self containment! and If you could feel the weight, you will get tired of that quick. This one, pull the pin shove both arms up and pin them! Super nice out of the way Design and 10 pound lighter! No loss in performance and much better quality. No question witch one I would buy after seeing both side by side! And there’s no welding, unless you want too.

No instructions were really included with the product. I should have known this was going to be a difficult install because they never even show a picture of this attached to the boom of a tractor. No matter what we tried, short of permanently welding it to the boom, we could not get it to not slip down and come in contact with the bucket's joint, which means the claw is way to close to the bucket for me to grab anything, let alone a log. This product might work with some tractors but I suspect they all have a similar issue. The company needs to come up with a lever clamping system that doesn't interfere with the top hydraulics and these things will sell like hot cakes. I love the powder coating and the thickness of the steel. I really wanted to like this product but its missing that one feature, that for me, drastically changes its usability. Thanks!

Installing this on my backhoe took about an hour and added a lot more ability to my machine. I installed this on my 9hp Harbor Freight towable backhoe and it worked with no issues. I love how adjustable it is, as long as it mounts onto the boom, you can pretty much position this thing anyway you need it. The rear pin is easy to remove and allows fast re-positioning for machines that don't have a control for the thumb. Shipping was fast and no packaging issues. Kinda hard to hurt this thing in shipping as it is designed to take a beating.

The price was right. I had to do it. The New Holland boom is about a 1/4" wider than the unit. The least confusing way to explain what I did is I cut the boom mount in half (not as bad as it sounds!) By doing this the thumb will now mount inside the boom mount, not outside. This means that once cut in half. The "knubs" left on the pivot hole of the thumb will have to be cut and ground flush for it to swing into the stow position. This was actually the longest part. The pin that the support arm for the thumb pivots on will have to be cut to allow the thumb all the way up. Remember the thumb used to come up on the inside. Once cut you will have to mark and drill holes on the inside & insert cotter pins on either side to hold it in place (see picture.) Last I drilled and bolted a 1/4 piece of stock to support the back side. (see picture.) I know all of this sounds deep. But it's not bad. You need a 4" cut wheel, a drill, a couple cotter pins, and 3 longer bolts for the top of the boom mount. My boom mount sets where it's at to cover clearances with the bucket as well as the bucket cylinder. You'll see as you get into it what needs to be tweaked. I picked up some really heavy boulders. Maybe 3' x 2'. A few hundred pounds. It did mess up the some teeth tips on the thumb. I wished they were harder. But for the price it did good. You can always pull the thumb off and throw it on the bench to beef it up. This could have been welded and saved some time and purchasing the 3 bolts. I wanted to be able to remove it if need be. Good Luck. Be careful. You know both the manufacture and Amazon won't be liable & not recommend mounting this any other way than instructed by the manufacture.

I liked the product but would not fit on my back hoe arm. To bad that it was not made to be adjustable.

Basically no instructions so lots of experiments. Installed it on a 3" Kubota B21 hoe Good fit. Likely going to be a long lasting and very useful addition.

The product image installed show a different product (or partial product). I got it installed in my TYM T25 TB65 back hoe. It slide perfectly in there, perfect size, but it took me a bit to understand that it hold in place by SIDE pressure of the plate, because the bolt doesn't align perfect to hold it from the top and bottom. I tried it just a little bit so far, and it worked ! I wish it could extend further, and I really wish it was hydraulic power already ! I'll do more test with it, but I feel it could extend a bit further, but I put it to the maximum it can be on the boom. So for the price, I think it really reasonable to start with ! The manual thumb from TYM was 5x the price of this one ! But a hydraulic thumb might be in my future if I don't go get a full size excavator which I really wish I had.

Very well built. Just needs a little bit of adjustment when installing and shims to make tight on boom.
