I have a John Deere MX5 on my 3720. I needed a 5 footer for going between trees. It is heaveier duty, but it makes the front of my 3720 light, even with the bucket.
The MX series is rated for 2" saplings... The LX 1". IF I was looking for something to cut real brush with all the time, I would get the heaviest duty one I could afford, or be welding supports on a lighter duty one.
My neighbor has a light duty 6' hog and I weld on that thing every week when he uses it at his deer hunting property.
You will also NEED a slip clutch, not sheer bolts.
