I saw this big truck with a huge grinder in two outside my neighbours yard, and decide to ask them about trimming my trees. They are very professional , and the price is not too bad.
Most of the time the gardners show up with saws to just trim, these guys come equiped with the big grinder/mulcher and lots of other equipment. I had 4 of my tall palm trees trimmed, as well as some other trees rounded and a root dug up.
The price was cheaper than some of those that weren't as well equiped. The other guys just pile the stuff into the back of a truck and haul it off. These guys actually look like they are pros.
