Smalltown, here are some pics and video of using the Bro-Tek thumb with my JD 990 and JD 8B BH. The bucket on the 8B is 18". The boom lift is almost 900 lbs. One of these rocks was far more than that and I found that if you drag it up close and then use the dipper you can swing it up and then move it. I have rocks all over my property this size. I am impressed what I can move with the 8B. It has an 8.5' reach. some of these rocks I realize I will not be able to move with the BH but hopefully I will be able to move them with the 990 and the 300CX FEL.

This link is just with the Bro-Tek mounted and also a bunch of pictures for changing out the thermostat and the radiator fluid on the 990.
