I recently posted about my decision to purchase a grapple and I decided on the R.H. LONG OBG2 for my NH T1530 45hp.
It was the best decision I had ever made after deciding to by a tractor. I have been working with it since the july 4 weekend I have moved large piles of brush, logs of increasing size and rocks and boulders. I ordered the grapple with the additional bars added to the bottom and back so I could use it as a rock and stone bucket.
There is no 1 perfect grapple since all the jobs are very specific but I feel this strong product, 56" size and added metal will meet all of my needs.
I also used it to clear a road. I had to walk with a chain saw and precut the area but after that I pushed, picked up and bullied my way through and in 2-3 hours cleared a level 200ft long x 10 woodland road.
So back to the original question of rocks and boulders a grapple is the way to go.
Now I will say that brush hogging HEAVY overgrown areas are still best done with my 72" bucket attached pushing all the growth down ahead of the tractor. The grapple is narrower then the read wheel base and mower and I started to get caught on large saplings. Also the tines on the front of the grapple would catch brush and start to pull it out vs pressing it down with the lowered, up tilted bucket.
I have tried to attach some pics and this was just my 1st and 2nd weekend learning how to use it.
