I was looking for a bucket truck. Have been looking hard at a used am 855 but found a low miles local am900 it is 72' I think I understand the non over center boom but it says 37' side reach. The only buckets I have used were forestry and over center you could do pretty much everything. Would a am900 b good for tree work or am855 b better. Any down falls I would need to know about? 72' would b sweet yes I climb. It has two buckets I would remove one. I have used a bucket once in 10 yrs and thought this would make my days much better.
