My experience with my Bobcat 643, which I've had for nearly 5 years, has been excellent. It was barely used prior to being purchased by me from a dealer that sold business equipment. I take care of most of my own house and lawn maintenance tasks as a homeowner (including concrete work). I transport dirt around the property, dig holes for posts, etc. using the machine to excavate basements. On each of these tasks, it has done well. Ford gas engine with 32 horsepower is inside. It has the great dirt-digging ability. It also possesses the dynamism needed to push successfully. I use it to build things for and around the house.
