American Built
I bought a Diamond and have used it one summer  on a Equip program ( NRCS pasture renovation program .It is a 60" mounted on a Case CX240 trackhoe My neighbor has a smaller one on his skid steer. He said he has problems with the motor mount bolts working loose.I checked mine and they need tightened also. Is this an issue with Diamond or all this type cutters ? I know they take a lot of shock load .Maybe I just need to keep on eye on this area.What are your thoughts. I think mine has in the 40 to 45 GPM flow. I usually start at the top of larger trees at an angle and work down.Larger to me is 10" to 12" base. Mostly 4" to 6" limbs overhanging the perimeter of fields.It works great on smaller brush 6" and smaller.I purchased from a major construction company dealer in the mid west.Never again !! Had an inexperienced person install it.
Thanks for your earlier input.
