I am still using it, after I broke it and Jerry sent me new heavier duty bolts. It was down a few weeks till the parts came and I got the job done repairing it. Then I bent one of the arms and the frame but was able to bend the arm back till it could close on the tree. My tractor has around 39 HP and the weight to go with it. It does a great job for small trees 2" to 3" in my soil and doing it the way Jerry shows on his video of gripping it and then rocking back and forth until it comes out. I was curling my bucket which was putting more pressure on the grapple arms and pin/bolts and it isn't strong enough to handle that obviously. Again, used with care and maybe reasonable diligence it does a fine job. I have cleared a lot of trees. I also had curled it pointing down to pick up a bundle of trees and maybe got it in the ground which is what Jerry said probably bent the arm. So, straight on with proper size of trees and a back and forth with tractor while lifting bucket has produced great results for me.
Jerry has two sizes of hydraulic rams which gives more or less gripping power and I have the bigger one.
I had a BX2200 and am skeptical whether it will work on your tractor unless the ground is very loose and the trees fairly small. Traction or the lack there of is the problem with the sub compact tractors and probably all tractors. 20HP in a tractor can do a lot but if you can't get traction and your doing more than lifting your usually coming up short. I'd want feedback from someone that owns one and using it on a BX before I'd make this big of an investment. Ask Jerry how many he has sold to BX owners and if they have said they have any issues and sure he'll be straight with you. Titan has one for half the price but it just opens/closes one arm while one arm stays in a fixed position. It indicates it weighs more but I think the hyd ram is smaller. It looks like it will remove small trees in a similar manner.
Mine is working fine now even though the frame is bent across the bottom and have a couple of hours use after I made the repairs with the parts Jerry sent me and I was able to bend the arm back into working position. Your BX probably doesn't have the power and weight to cause the damage I was able to do with the power and weight and aggressive use I was doing.
