TB108

With its ultra-compact design and an undercarriage that can be retracted to less than 30 inches, the TB108 can easily work on job sites with narrow or limited access; areas that would otherwise require manual hand labor.  This makes the TB108 ideal for the rental and construction markets, and makes it an outstanding choice for compact excavation, interior demolition, landscaping, and utility installations.
